Plant Growth Regulators: know your region.
P
lant Growth Regulators (PGRs) can be either naturally occurring plant
hormones or synthetic compounds. PGRs have long helped fruit
growers promote, inhibit or modify the physiological traits of their crops.
Some (such as MaxCel®) chemically thin apples to optimize crop load
and reduce stress on the tree. Others (ReTain® and ProGibb®) help
manage maturity… extending the growth window and enhancing quality.
Meanwhile, a product like Promalin® can alter fruit shape to meet
market expectations.
Using a Plant Growth Regulator is as much an art as it is a science. Your
climate, weather conditions and growing season will be determining factors
in deciding optimum rates and timing. What works in the Okanagan will
likely be different from practices in Ontario and the Annapolis Valley.
For advice on how to get the best results from these Plant Growth
Regulators, talk to your local retailer. They have extensive experience
knowing what tips and tricks will give you the best results in your region.
If you have a question they can’t answer, call Nufarm toll-free to speak
to one of our technical representatives: 1-800-868-5444. We’d be
happy to help!
Murray crops apples, sour cherries, peaches and pears on his 750 acre
orchard. They are one of the preferred suppliers to Chudleigh’s and their
Blossom line of individual sized apple pies.
Not surprisingly, Murray Porteous is always among the first to try a new
product if it has the potential to help him grow a better, more profitable
crop. He estimates that he has participated in over 200 research trials
since he joined the family business as a partner in 1989.
“I’ve used every one of Nufarm’s horticultural products since the year it
was registered,” Porteous reveals.
With that being the case, we thought who better to ask about his
thoughts on our line of Plant Growth Regulators:
The importance of
innovation.
ReTain: “I’ve used it for years. It helps reduce ethylene production in
more advanced fruits. You’re colouring a higher percentage of fruit in
the tree, which helps with labour efficiency. Don’t use if there is stress
on the tree.”
Murray Porteous is President of the Canadian Horticulture Council.
He strongly believes that access to new technologies is critical to the
success of the Canadian orchard industry. Particularly since Canadian
growers are competing directly with foreign producers who stand to leave
us behind if we are not diligent.
This year, Porteous helped launch a new project called The Legacy
Initiative. The goal is to partner with industry to create a healthier, stronger
fruit and vegetable sector.
“We’re very committed to proprietary products… and are trying to make
a more efficient, cost effective system to bring new products into this country.”
Porteous comes from a long line of orchard growers on both his mother
and father’s side. As owner of Lingwood Farms in Simcoe, Ontario,

Promalin: “I’d look at it on Red Delicious. It makes sense for growers
who are marketing their own apples and can get a premium for typiness.”
MaxCel: “I really like it. I consider it a safe and very effective thinner.
I also think I get more size response and consistency with MaxCel than
I do with NAA. You get a better price per apple and it improves your
labour efficiency.”
ProGibb: “It helps trees overcome
damage from Cherry Yellow Virus and
helps establish the fruit bed for the
following year. Even if we don’t have
a crop we’ll use ProGibb.”

Plant Growth Regulator
Cherries with crunch.
Bob Troupe
BC and Ontario growers know the value of firm fruit.
“C
herry growers learned a long time ago that firm, crunchy
cherries do well in the marketplace,” Hank Markgraf says with
a twinkle in his eyes.
Markgraf is the Field Service Manager for the Okanagan Tree Fruit
Cooperative (and is a grower himself). Over a third of all cherries grown
in BC are shipped to the grower-owned cooperative for packaging. This
year, they brought in 9 million pounds of sweet cherries for the fresh
market.
“Our job is to assist the growers with whatever horticultural questions
they have so they can grow the best crop.”
One of the pieces of advice that every cherry grower gets is the
importance of using a gibberellic acid (GA3) plant growth regulator,
such as ProGibb (the most widely used GA3 in the world).
“It’s primarily used as a fruit firmness enhancer,” Markgraf explains.
In other words, it is the secret ingredient that provides the crunchy
cherries that customers demand.
Typically applied at pit hardening, ProGibb offers many other advantages.
Cherries stay on the branches longer, which increases fruit size. It
extends the harvest window. And since it makes the fruit harder, ProGibb
cherries stand up better once they are picked, packaged and transported.
Finally, it can increase resistance to postharvest disorders.
“I don’t think we could grow sweet cherries without some form of
gibberellic acid being applied,” admits Markgraf.
ProGibb is relatively new to Canada, but it has become an immediate
hit with growers. As the only soluble granular on the market, it is easier
to handle than other formulations. ProGibb is much more soluble than
products that come in the tablet formulation or those that are sold as
technical grade gibberellic acid. Better solubility means better
bioavailability of the active
ingredient. ProGibb is also safer
to handle and store than liquid
products, which are classified as flammable.
Bob Troupe was an immediate convert. Troupe, whose orchard is
located on the southern shore of Lake Erie (in Jordan Station), says it is
a pleasure to work with because it mixes and measures extremely well.
“We think ProGibb is a good product. It is easier than the products
we used to use.”
On his orchard ProGibb is applied a minimum of 21 days before
harvest, when the cherries turn straw coloured.
Unlike BC, gibberellic acid isn’t used by all sweet cherry growers
in southern Ontario. For Bob Troupe, it’s his secret weapon.
“We’ve gained a reputation for having better, harder cherries. It’s
turned into a bit of a sales advantage. We’re able to demand more
dollars for the end result,” he beams.
ProGibb also performs in sour cherries.
Firmness is not a factor in sour cherries. But ProGibb offers another key
benefit. It improves the fruiting of trees infected with cherry yellows virus.
ProGibb promotes spur formation and reduces the occurrence of blind
nodes. Applied as a maintenance spray every year at 14 to 28 days
after bloom, it keeps sour cherries productive for years.
Tip:
Apply ProGibb during
warming trends. Three days
at 15°C to 26°C is ideal!

Not your type?
Promalin® helps growers shape
apples to meet expectations.
C
harles Stevens likes to tell the story of how Washington
State growers came up with a unique way to market their
Red Delicious apples. Wanting to establish a reputation for the
perfect unique apple, they began using a plant growth regulator
called Promalin® to manipulate the apple’s shape.
It was a brilliant move. They changed the consumer’s expectation. Ever since, the public is convinced that a Red Delicious is
supposed to be elongated (even though this is not the natural
shape).
“So in order for me to compete against Washington apples,
I have to do the same thing,” the Newcastle, Ontario grower says
with a chuckle.
Stevens has had great success using Promalin over the years.
It gives him the “typiness” the buyer is looking for. It also helps his
apples get a little denser – so they weigh more and don’t bruise as
easily.
Promalin is a combination of two PGRs: 6-benzladenine and the
gibberellins (GA4 and GA7). It can be applied between early king
bloom to early petal fall.
Currently in Canada, Promalin is registered to “improve the shape
of Red Delicious.” Nufarm, together with Valent is working to get the
label expanded to include other varieties and applications.
And while it elongates Red Delicious apples, Promalin won’t
stretch your finances!
Promalin for enhanced
branching and russet
control?
In the United States, Promalin is registered to enhance
branching in nursery trees. Currently, this application is not on
the Canadian label. John Cline of the Ontario Agricultural
College in Guelph would like to see this change, and is
supportive of Nufarm/Valent’s efforts to expand the label.
“Growers are looking for it. There are some varieties that
don’t branch enough. We’ve done some preliminary studies that
show these trees will respond to Promalin.”
Stan Swales, General Manager of Grower Supply Company
Ltd. in British Columbia has worked extensively with Promalin.
He points out that Promalin is widely used in Europe for
providing russet control in Golden Delicious… something
he hopes will be added to the Canadian label.

Thin to win!
No thinner offers more upside than MaxCel®.
I
t’s common knowledge that thinning an apple crop at the right time will
result in less fruit, but higher returns per acre.
While it seems counter intuitive, by removing the smaller, weaker fruit
you are ensuring the apples that remain will receive more of the tree’s
energy. And therefore, grow larger.
With high labour costs and tight time lines, hand thinning is usually not
a practical option (although many orchards still do some manual thinning).
Fortunately, growers have plant growth regulators such as MaxCel® to
handle the bulk of their thinning needs.
Over the past 15 years research biologist Doug Nichols has observed
a dramatic increase in the use of chemical thinners by apple growers on
the east coast – a trend reflected right across the country.
He and the rest of the team at the Nova Scotia Fruit Growers
Association have been very active in educating growers on the value of
thinning agents.
“When you reduce crop load, there are a whole lot of positive
benefits,” Nichols explains.
“First, you have larger fruit size. For fresh and process markets, there is
a demand for fruit that is greater than 2 ¾”… apples that weigh between
180 to 200 grams. Coupled with increased size, fruit tend to be better
coloured if there is less of it on the tree. Therefore, more marketable fruit
can be harvested.”
“I find MaxCel is awesome for return bloom,” Kemp says.
He thins 90% to 100% of his orchard. As many growers will tell you,
thinning is as much an art as a science. Crop load differs from year to
year, which will affect how much MaxCel to apply.
Kemp follows a basic rule of thumb.
“For every 10 blossoms they say you only need one apple.”
Torrie Warner says that the blossoms for the following season typically
start to form in July. If the tree is stressed at that time, these blossoms won’t
develop – and the tree won’t bear as much quality fruit the following
season.
“MaxCel prevents the tree from going into biennial bearing. If you
have too many fruits, the tree is stressed.”
Warner says thinning with MaxCel not only reduces stress, but the
remaining fruit are larger and of better quality. As a result, they command
a higher price.
“With the larger size, you get reduced yield per acre… but you get
consistent production year to year. And a higher price per bushel.”
Now that’s sound logic an experienced grower can appreciate!
Reduce stress to prevent biennial
bearing.
Like other thinners, ensuring return bloom is a key reason for using
MaxCel.
Because thinning reduces the stress on a tree, it is a valuable tool for
promoting healthy, productive blossoms year after year.
Kirk Kemp of Algoma Orchards (Newcastle, Ontario) and Torrie
Warner of Warner Farms (Beamsville, Ontario) have both used MaxCel
on their apples.

The only thinner that
promotes cell division.
A
All thinners will promote some additional growth by reducing
competition.
However, to see how innovative and advantageous MaxCel is…
you have to compare apples with apples.
If you did the same amount of thinning using MaxCel and naphthalene
acidic acid (NAA) based thinners, the MaxCel apples will be bigger. That’s
because 6-benzyladenine (6-BA) – the active ingredient in MaxCel – is the
only thinner that gives you the added benefit of stimulating cell division.
MaxCel’s unique 1.9% formulation of 6-BA is also best-in-class for
absorption and plant uptake.
In the words of Charles Stevens, co-owner of Wilmont Orchard in
Newcastle, Ontario: “Size is everything.”
Stevens believes than anybody can grow a mediocre apple. But in order
to be a top grower who can compete with international producers, it is crucial
to adopt every new technology that can provide a competitive edge.
MaxCel is a product that immediately attracted his attention.
“I use MaxCel not only for thinning, but to enhance the size of the apple.
If I can put MaxCel on and make every apple 1/8” bigger, the return is huge!
I’ll have more apples paying at the higher price at sell back – and they will
cost me less to pick.”
MaxCel increases cell division in that critical growth period 30 days after
bloom. According to Stevens, if you have a small apple after that 30 day
period it will never get big: no matter how much you water it.
Stevens uses MaxCel on 80% of his apples. This includes Galas, Ambrosia
and Red Delicious. Typically he will spray MaxCel twice. First at 5 mm and
then for thinning at 10 to12 mm. Often he will tank mix with Sevin® (which is
believed to further enhance the effectiveness of MaxCel).
Stevens says that his pickers can immediately tell the difference between
apples that were sprayed with MaxCel and those that weren’t. The size and
weight is that noticeable.
On the other side of the country, Grower Supply Company serves 2,500
customers through its five locations in the BC interior. They are
a commercial wholesale supplier of orchard, vineyard and farm
products. As the company’s General Manager, Stan Swales has
observed the size difference at grading.
“When we started applying it and then measured thousands
and thousands of apples, we found that we got a 2 mm
difference in fruit size. It’s something you can’t see visually,
but when it goes over the grader you see that ‘one box size’
change. That gives you 8% more fruit.”
Tip: Like any Plant Growth
Regulator, MaxCel works
best in warm weather.
For best results, apply
MaxCel ahead of a
warming weather trend.
Two to three days where
the daily maximum
temperature reaches
at least 18°C following
application is ideal.
Premium returns.
Back in southern Ontario, Charles Stevens says many growers
prefer to use a lower priced thinner. However, he says the
biggest decision should be based on how you can increase
your profits by using a new technology.
“If it can give me a greater return on investment, I don’t
care if it costs a little more.”

ReTain
®
Plant Growth Regulator
Time is on your side.
G
rowers have a lot of reason to be stressed out at harvest time.
Fortunately, there is one product that puts your mind at ease during
this critical period of production.
ReTain® is a unique Plant Growth Regulator that helps optimize crop
maturity and quality. It delays apple maturity by seven to ten days.
Unlike NAA, ReTain is not just a stop drop product that simply “sticks”
apples onto the tree. ReTain actually inhibits ethylene production. This
offers several advantages that can directly contribute to improved profit
margins.
Because ReTain delays the maturation of apples, it can be used as a
powerful harvest management tool. When you have an extra week to
pick each variety, you can ensure that each block is picked in prime
condition. As well, you can harvest the crop with fewer pickers.
ReTain also enables additional late season growth. Leaving the
apples on the tree for an extra week can have a very significant
impact on the final size and improve colour.
“We’re getting growers to use ReTain to make their lives easier,”
reveals Hank Markgraf, the Field Service Manager for the Kelowna
office of the Okanagan Tree Fruit Collective.
He notes that ReTain is especially popular with the Okanagan’s
larger-scale growers who are producing 200 to 300 bins of McIntosh,
Gala and Spartans. The picking can be staggered so nothing is left
behind. Because smaller crews are required, the labour savings add up.
“If you’re trying to take off 1,000 bins in a 10 day period, giving
yourself five extra days is a huge advantage.”
Markgraf gets very animated when he talks about ReTain’s impact
on sizing, particularly in a Gala apple, which is probably the most
responsive.
“By giving the fruit 5 or 7 more days on the tree, you gain a box
size,” he says with a smile.
Based on experience, Markgraf has seen how ReTain can easily
help a grower go from 100 apples per box to 88 per box.
“When you look at a size 100 and you go to a size 88, there’s a
huge price difference the grower will receive from the packing house.
That extra box size can mean a 5¢ to 8¢/lb difference. That easily pays
for the ReTain!”
There are numerous other advantages related to fruit quality.
ReTain also helps:
• Enhance firmness
• Improve colour
• Reduce water core
• Reduce stem bowl splits and cracking
• Improve post-harvest quality
The ReTain label calls for application 4 weeks prior to the anticipated
harvest date of the untreated fruit. Many of Hank Markgraf’s customers
will go in earlier, which is not uncommon for Okanagan growers.
With all of these advantages, it is no wonder that ReTain growers
across the country can rest a little easier at harvest time.

A conversation with John Cline.
John Cline
N
ufarmer recently caught up with John Cline at the Ontario Agriculture
College, University of Guelph. Cline is an Associate Professor of
Tree Fruit Physiology in the Department of Plant Agriculture.
Nufarmer: Why use a stop drop?
In addition to getting his thoughts on Canada’s apple industry, we
asked Cline to explain some of the science behind ReTain®.
Cline: Some apples drop prematurely before they are ready to be
commercially harvested (such as McIntosh and Honeycrisp). If the fruit
drops, growers can’t sell it for fresh market. So there is an immediate
benefit in terms of having more fruit.
Nufarmer: Have you noticed a change in the Canadian
apple industry over the years?
Nufarmer: How long does ReTain extend the life of
McIntosh?
Cline: Acreage is declining, production per hectare is increasing and
overall value of the industry is increasing. We’re seeing new varieties
like Gala, Ambrosia, Honeycrisp and others becoming more important.
Primarily because they’re high value, fresh eating apples.
Cline: Generally 7 to 14 days.
Nufarmer: What does it take to be a successful grower?
Cline: It’s an intensive, long-term learning endeavor. By the perennial
nature of growing apples, they require patience, planning, hard work
and foresight. But when it comes down to it, there is not just one way
to grow an apple. A keen observation of what works and what doesn’t
is something you can’t learn in a textbook. Expertise is acquired through
experience and time.
Nufarmer: ReTain is a relatively new PGR that was
introduced to Canada in 2005. It is a stop drop product.
It helps with harvest management. And it has a positive
impact on sizing in the late growth stage. How does it
work?
Cline: AVG, the active ingredient in ReTain, is effective by blocking the
production of ethylene in the plant tissue. Ethylene affects several aspects
of plant development, including fruit maturation and ripening and
abscission. ReTain also acts on the abscission layer on the fruit stem,
which holds the apple to the tree. By slowing this process down, fruit
do not drop as readily.
Nufarmer: What about varieties that don’t have this
problem?
Cline: The other thing ReTain allows a grower to do is to manage
the crop and harvest schedule. They may not spray the entire crop;
they might spray half. This way they can pick the unsprayed half first
and the sprayed half later.
ReTain is also very useful in “Pick Your Own” orchards where the crop
is not harvested all at. Growers rely on the public to pick, usually over
an extended period of time.
Nufarmer: For many growers, the biggest advantage is
the boost in size they get by using ReTain.
Cline: As long as the apple is on the tree it continues growing. If you
leave it a week to 10 days longer, you can expect an extra 5% gain
in weight.
Nufarmer: Does it help with quality?
Cline: Because it slows maturity it can help with quality. If you compare
an apple picked at day zero (of harvest) and one that was sprayed
(and picked) 7 to 10 days later, ReTain would improve the quality of
the later sprayed fruit.
New pricing structure on ReTain puts Canadian and US costs on par.
Good news. Nufarm has recently lowered the price on ReTain to bring it in line with what
American customers are paying. Now ReTain offers growers on both sides of the border the
same great value.

Canada prepares for arrival of
Brown Marmorated Stink Bug.
I
n a proactive move to prepare for the impending arrival of
Brown Marmorated Stink Bug (BMSB), the Pest Management
Regulatory Agency (PMRA) has approved Clutch® 50
WDG insecticide for suppression of BMSB on pome fruit, stone fruit
and grapes in Canada. Clutch is the second Canadian minor use label
expansion for this invasive pest.
Hannah Fraser, Entomology Program Lead (Horticultural Crops) for
Ontario Ministry of Agriculture, Food and Rural Affairs is one of Canada’s
leading authorities on this impending problem. She says BMSB has proven
to be incredibly difficult to control in the United States. Having insecticides
such as Clutch will be key components in a multi-pronged IPM approach
that will eventually include: monitoring, biological controls, trap cropping
and attract & kill solutions.
“I think all those strategies will be important for managing this pest,”
Fraser predicts. She says more information on the biology of BMSB is
required to optimize pest management solutions.
Originally from Asia, this species was introduced to North America
in the mid-90s. It is already a significant problem in Mid-Atlantic States
south of the border. In 2010, it caused $37 million of damage in apple
crops and wiped out nearly half of the US peach crop. BMSB is an excellent
hitchhiker. To date, it has been detected in 39 states and has been
intercepted coming into several Canadian provinces on imported goods
and in vehicles.
The news gets worse. The first established Canadian population was
recently discovered in Hamilton, Ontario. Fraser suspects it is also present
in Burlington, Toronto and Newboro, based on homeowner finds. This is
a concern, as BMSB often is found in urban areas before it migrates to
the countryside.
Hannah Fraser indicates there is a great deal of research and learning
yet to be done. Here are a few of the things we do know:
•BMSB attacks a wide variety of plants (up to 300 hosts have been
reported), including tree fruit, berries, grapes, vegetables, corn,
soybeans, plus ornamental trees and shrubs.
•As a foreign invader, it has no effective natural enemies in North
America.
•Woody hosts such as Tree of Heaven and Catalpa are preferred
hosts, and support population build-up through the season. In
Ontario, Buckthorn (also invasive) appears to be a suitable
reproductive host.

Topping Ontario’s
Least Wanted List:
Brown Marmorated
Stink Bug
•Damage is caused by both nymphs and adults.
•Crops that mature later in the season (such as apples) are
particularly susceptible to economic injury.
•BMSB are highly mobile and readily move between a number
of host plants and crops throughout the season.
•They often spread to crops in waves, which makes it tough to
control them in a timely manner.
If you suspect you may have a problem with BMSB, the first thing to
do is to report it to your local provincial agriculture authorities. In the
meantime, spraying a product such as Clutch is a preventative measure
orchard growers can take in areas where infestation is a concern.
Consult provincial specialists for more information on recommended
pest management programs for BMSB in your area.

Curbing plum curculio with Clutch .
®
P
lum curculio is a major pest in Ontario. Clutch® insecticide is helping
control this ugly critter in cherries, plums, peaches, nectarines, apples
and pears.
The insect migrates into the orchards at bloom through petal fall and begins
to cause damage after the petal fall stage. A telltale sign of infestation is a
crescent-shaped entry mark on the fruit. Once inside it lays eggs. Larva
will feed on the fruit, which remains on the tree – scarred and malformed.
Applied at the shuck split/shuck fall stage (post bloom), Clutch provides
long residual activity and is highly lethal to plum curculio via contact and
ingestion. Clutch is a systemic compound with translaminar movement
(meaning it penetrates leaf tissues and gives protection of the entire leaf)
when applied foliar. This enhances the protection of the tree’s canopy
and fruit. Clutch delivers plum curculio control in two ways: first, causing
mortality of adults by contact and second, providing residual control for
migrating adults. In addition, Clutch can reduce oviposition (egg-laying)
and fertility of eggs when fertilized females are exposed to the compound.
Clutch’s length of control lasts 10 to 14 days (depending on the
rate). Sometimes a second application is required (something grower
Bob Troupe of Jordan Station, Ontario humorously refers to as “Double
Clutching”).
“Clutch is working really well. I don’t know if there’s another product
as effective,” Troupe concludes.
Clutch delivers plum curculio control in
two ways: first, causing mortality of
adults by contact and second, providing
residual control for migrating adults.
DiPel insecticide meets changing demands
of export and organic markets.
®
D
iPel® is the world’s leading biological insecticide. This is no
coincidence. It is one of the most effective products for controlling a
broad spectrum of worms and caterpillars (Lepidoptera). Plus, DiPel is safe
for growers, pollinating bees and animals; it’s easy to use; it stores well;
and it offers superb value.
Equally important, its creator, Valent BioSciences Corporation (VBC) has
been very active in working with governments and regulatory bodies around
the world to ensure the product is recognized for its organic nature…
and for meeting strict standards involving residue.
John Hren, VBC’s Global Business Manager, has helped lead the
charge.
“In order to attain the maximum value for your harvest, you need to be
able to target higher-value market segments and you need to have flexibility
in your plans for distribution.
“Regulators and fruit processors instantly understand there is not a
residue issue with DiPel,” Hren explains. He says this helps Canadian fruit
growers export to lucrative markets such as Taiwan or Japan, where there
are strict MRL standards.
Because DiPel is an insecticide that is derived from naturally occurring
elite strains of bacteria, it is universally approved for meeting organic
farming guidelines as well.
Bt toxins and Bt spores form the active ingredient, and are produced
naturally by these bacteria. When ingested by the worm, the Bt toxin
freezes its gut and will stop the caterpillar from feeding. The Bt spores
act as a synergist in the process.
DiPel is applied at the early juvenile stage after egg hatch – before
the caterpillar grows, gets mobile, and starts chewing the plant leaf
and damaging the crop. Rates are flexible, depending on the level of
infestation. This insecticide can be safely used on a wide variety of
orchard fruits, including apples, pears and stone fruits.
More modes of action to prevent
resistance.
There is growing evidence that overuse of Group 28 insecticides may
lead to resistance as caterpillars evolve to fight insecticides with this mode
of action.
Valent Biosciences’ John Hren feels that DiPel can play an important
role in a grower’s overall resistance management strategy, and help stave
off resistance to a particular chemical Group (such as the Group 28s).
“If you start losing efficacy due to pest evolution, you’ll also incrementally
start losing yield as well,” Hren says.
“DiPel can stop that. It has multiple modes of action. It has different
types of crystal toxins, each with its own unique receptor site in the insect
gut. So not only is it hard for caterpillars to develop resistance to DiPel,
DiPel also helps growers keep other products viable, longer.”
Whatever market you are aiming for, DiPel gives you the assurance
of effective worm control and greater flexibility in marketing your fruit.
And any time you can help fight resistance, it’s worth the effort!

Chateau
®
Herbicide WDG
Not seeing is believing!
New residual herbicide keeps
broadleaf weeds out of sight.
I
t takes a lot of energy for a tree to produce fruit. So the last thing you
need is to have a carpet of no-good, freeloading broadleaf weeds
competing for water and nutrients.
Chateau® is a pre-emergent herbicide that provides season-long
residual control of pigweed and other tough broadleaf weeds that are
common in tree crops.
Growers will typically tank mix Chateau with glyphosate. The
glyphosate will control any emerged weeds, while the Chateau will
prevent future weeds from poking up.
“Chateau is the first new residual herbicide we’ve had in years,”
says Charles Stevens of Wimont Orchards in Newcastle, Ontario.
According to Stevens, pigweed, lambsquarters and many of the
weeds in their part of the province have developed resistance to the
older chemistries, such as simazine. So this makes Chateau a welcome
addition.
After trying Chateau for the first time, he was very happy with its
ability to keep that vital three foot perimeter under the tree, free of
broadleaf weeds. He felt the product delivered as promised for
controlling pigweed.
Chateau can be applied up to two times per growing season. It can
be sprayed in the spring before bud-break, either on its own or tank
mixed with glyphosate. Or it can be used once the crop has been
harvested. Contact with green bark or foliage should be avoided.
All applications to pears, or within 100 metres of pears, must be
made two months before bud-break in the spring or after final harvest.
Apply to dormant pears only.
