Sponsoring Multiple Studies for Disease and Insect Control
Biorationals For Sustainable Agriculture
Our focus with biorational products provides sustainable solutions for agriculture, including biological fungicide for the control
of both fungal and bacterial diseases. They not only reduce disease pathogens, but also decrease crop stress, enhance plant
physiology benefits (ISR & SAR), stimulate root growth and maintain higher quality postharvest shelf life.
Three Modes of Action
Companion® Liquid Biological Fungicide contains a unique strain of Bacillus subtilis GB03 that has three different modes of
action to fight disease-causing pathogens. By releasing a broad-spectrum antibiotic (Iturin), it disrupts the pathogens cell wall
causing desiccation. Forming a protective zone around the roots, it boosts the plant’s immune system to fight disease, Induced
Systemic Resistance (ISR), restricting the development of diseases. It also reduces the potential of the pathogen to develop resistance. In all studies crop yield was increased.
Research trials evaluated the efficacy of Companion® Biological Fungicide and “TKO” Phosphite 0-29-26, in combination
with commonly used fungicides, and alone, for the control of disease and yield increase. They focused on improving cucumber
and squash crops yield, fighting the diseases Downy Mildew (Pseudoperonospora cubensis) in cucumber and Powdery Mildew
(Podosphaera xanthii) in squash.
Trials with “TKO” Phosphite, in combination with the pesticides, improved the overall disease control when compared to the
stand alone chemical. Companion Biological Fungicide in combination with chemical fungicides also realized improved efficacy
of the pesticide. Additionally, there is a zero-day, pre-harvest interval to control late season diseases. Companion is an ideal
addition to resistance management programs, as its complex modes of action greatly reduce the ability of the pathogen to
develop resistance.

DISEASE EVALUATION:
Foliage / Disease severity rating began on 18-Apr. Severity was evaluated
using the overall area of diseased foliage. 5 representative plants, per replicate, per commodity were evaluated (means calculated using Horsfall-Barrett Scale (1-10)). Trial was inoculated on 8-Apr, following the first
applications, by placing infected leaves at the ends of each commodity, in
each plot. Similar inoculations continued on a weekly interval until disease
pressure was established.
DISEASE RATING DATES:
18-Apr, 25-Apr, 2-May, & 9-May
APPLICATION DATES:
7-Apr, 14-Apr, 18-Apr, 21-Apr, 25-Apr, 29-Apr, 2-May, & 6-May
APPLICATION METHOD:
CO2 Backpack Sprayer
TRIAL LENGTH:
Seeds sown on 25-Mar. Weekly applications began on 7-Apr. On 14-Apr
application interval was shortened to every 4 days. A total of 8 applications
were made. Applications were of either single product or 2 products in tandem.

Downy Mildew can develop at any stage of
crop development, including the cotyledon
stage, affecting plants of all ages, especially
foliage which directly impacts the plant’s
photosynthetic ability, resulting in stunted
growth. The application of TKO Phosphite
and Bravo reduced the disease incidence
over the control by 68% and improved the
overall performance of Bravo by an additional 31.4%.

COMPANION+ BRAVO WEATHER STIK
It is a matter of scientific record that there is
a synergy with certain biologicals when used
both as tank mix with chemical pesticides, or
in rotation. Since Companion is a grampositive bacteria, it is not effected by chemical fungicides and will facilitate their
efficacy. The results of this trial demonstrate
that Companion Biological Fungicide improved efficacy of the Manzate Pro-Stick by
28.4%, adding even more certainty to avoiding resistance problems. Over all disease
control over the untreated control was 65%.

Preventive sprays are essential in the control
of Downy Mildew, before spores blow in.
Overall improved efficacy compared to the
untreated control was 57.6%. Companion
improved the performance of the Bravo by
an additional 8.5%.

Powdery mildew can over winter. Cucurbits
are very susceptible to Powdery Mildew. Resistance to fungicides have been found in
all parts of the US. Biorationals alternating
or in combination with fungicides can reduce resistance problems. TKO Phosphite
and Bravo reduced the disease incidence
over the control by 76% and improved the
overall performance of Bravo by an additional 9.3%. Ranman was ineffective in controlling the disease.
