Transform™ insecticide for cucurbits
What is Transform insecticide?
A systemic foliar insecticide with extended residual control
of aphids and greenhouse whitefly in a wide range of
vegetable crops. With a novel mode of action and no
cross-resistance to any other chemistry, Transform is the
only Group 4C insecticide on the market.
Transform contains 240 g/L Isoclast™ active as a
suspension concentrate.

Cucurbits1 including:

DIRECTIONS FOR USE in Cucurbits
Monitor crops for pest species by regular field scouting.
Target sprays against insect populations when they exceed
threshold levels. Make repeated applications at 7 day
intervals as new infestations occur.
Restraints: DO NOT apply more than 4 times to any cucurbit crop in any one season. DO NOT use Transform in protected cropping situations (greenhouses, glasshouses, etc.)
RATE
CRITICAL COMMENTS
200 to 300 mL/ha
400 mL/ha
Use higher rate under heavy aphid infestations or if
longer residual control (>7 days) is required.
Ensure accurate species identification.
Pest names: Green peach aphid (Myzus persicae), Greenhouse whitefly (Trialeurodes vaporariorum), Melon aphid (Aphis gossypii).
1 Field grown only.
* Including green peach aphid populations resistant to other insecticides.
Where does Transform fit in the spray
program?
Applications should target pest populations before they build to
damaging levels. Transform is not affected by temperature so
can be used with confidence in both warm and cold conditions.
Ideally, if a Group 4A product has been used as a seedling
drench or soil treatment (e.g. imidacloprid), Transform should
NOT be the next aphicide used (acceptable alternatives include
pirimicarb and Movento®).
Compatibility
Transform is a robust suspension concentrate formulation and is
compatible with most commonly used crop protection products
used in vegetable production. Always conduct a bucket test with
any proposed tankmixture to confirm physical compatibility. Take
special care when making tank mixtures that require the addition
of adjuvants.
Adjuvants
Addition of a non-ionic wetting agent is not required in
cucurbits. If a wetting agent is to be added, ensure it is from a
reliable source, e.g. Agral® or Chemwett 1000.

Spray application
Apply a medium quality spray in a minimum of 250 L/ha water.
Increase water volumes for applications to large leafy crops.
Use the cleanest water available within a pH range of 5-9.
Thorough crop coverage is essential, especially when targeting
whiteflies. Transform is approved for application by aircraft in
vegetables.
Selectivity to crops
Transform is very safe to all crops. Transform is approved for
use in a range of fruit crops and vegetables at higher rates than
are required for aphid control in cereals so crop selectivity has
been very well established.

Selectivity to crops
Transform is approved for use in a range of fruit crops and
vegetables so crop selectivity has been very well
established. Caution is urged whenever tankmixtures are
made, especially those that require addition of adjuvants.
Consult your Dow AgroSciences representative before
making tankmixes with these combinations.
Withholding periods (WHP)
Harvest WHP: 1 day.
NB. For cucurbits grown for export markets, consult your exporter
before using Transform. Many overseas markets do not yet have
MRLs established for Transform.
Safety to predators and parasitoids and pollinators
Using Transform in preference to older broad-spectrum
insecticides will help preserve lacewings, ladybeetles and
aphid parasitoids in the crop.
Pest biology
Aphids deprive plants of nutrients and, as a by-product, they
excrete honeydew which becomes covered in sooty mould,
making the produce unmarketable. Furthermore, the
presence of aphids (dead or alive) in produce is highly
undesirable. Possibly their worst feature is their ability to
vector virus diseases which are untreatable and can virtually
decimate the crop. Aphids can invade at any time from crop
emergence onwards.
DO NOT apply Transform to flowering crops while bees are
foraging. Spray applications made early in the morning or
late in the afternoon/evening when bees are not foraging
should be safe. Bees generally do not forage while
temperatures remain below 12°C.
