Reduced Aphids from 19 Aphids/Leaf to 4 Aphids/Leaf

Cotton Aphid Control on Cucumber

HYDROVANT and Brigade (Bifenthrin) for Cotton Aphid control on Cucumbers in San Joaquin Valley, California. The graph shows the untreated check, the Brigade alone at the standard rate and the .1% HYDROVANT and Brigade at the standard rate.

Conclusion: 14 days of excellent control were obtained with HYDROVANT at .1% and Brigade at the standard rate. Note that Bifenthrin, a member of the Pyrethroid family, typically struggles to maintain acceptable levels of Aphid populations for more than 5 or 6 days.

Very Effective with Switch Fungicide for Gray Mold Control

Mold Control on Blueberry

Visalia, CA (San Joaquin Valley); Blueberry (var. ‘Emerald’); Applications made by CO2 powered experimental sprayer at 96 gallons/acre. Spray was directed from each side of the blueberry row; plants were completely wet from the spray. There was no crop injury observed on leaves, buds or developing berries. Wetting was excellent on leaves and stems with Hydrovant-fA + Switch. There was no mixing or spraying issues with the tank-mixture of Hydrovant-fA + Switch. Hydrovant-fA + Switch resulted in significant reduction in the number of berry shoots infected with Botrytis spp. compared to Switch applied alone.

Excellent Protection with Abound Fungicide for Brown Rot Control on Almonds

Disease Control on Almond

Reedley, CA (San Joaquin Valley); Almond (var. ‘Nonpareil’); Applications made by a handgun sprayer at 189 gallons/acre. Trees were sprayed to run-off. There was no crop injury observed on leaves, flowers or developing nuts. The Hydrovant-fA + Abound did an excellent job of wetting the tree branches, flowers and leaves. There were no mixing or spraying issues observed with the Hydrovant-fA treatments. The brown rot infestation was low whereas the shot hole infestation was high.

Significant Increase in Weed Control

Glyphosate plus Hydrovant

Results show that by combining glyphosate at a 50% rate with Hydrovant-fA, efficacy increased significantly in controlling broadleaf weeds and grasses. Weeds and grasses tested included: Hairy Crabgrass, Thistle, Grass, Argentine Fingergrass, Jungle Rice and Common Purslane.

  • All treatments applied with Hydrovant-fA resulted in a 128% – 152% increase in weed control.
  • 50% rate of Glyphosate + Hydrovant-fA performed significantly better than Glyphosate alone.
  • Evaluation after 8 days saw the fastest and greatest weed control.

Gets Systemics into the Plant

Triadimenol plus Hydrovant

This study objective was to determine level of residues of triadimenol in pumpkins following seven foliar applications of BAYFIDAN 250 EC Fungicide. In the analytical phase of the study, samples of the pumpkin (whole fruit) were analyzed for residues of Triadimenol. The study conducted under the OECD Principles of Good Laboratory Practice, consisted of one field site at Glenore Grove in the Lockyer Valley of Queensland, Australia.

Conclusion: Seven days after the last foliar application, the pumpkins treated with Triadimenol + Hydrovant-fA resulted in 2.8 times the Triadimenol in the tissue of the pumpkins than those treated with Triadimenol alone. No symptoms of phytotoxicity were observed during the study.
