Pre & Post-Emerge Herbicide Research

Improved Chateau Pre-Emerge Herbicide Weed Control

Replicated Trial – Weed Control Mixed with Chateau 51 WDG / University of Florida, SWFREC Dr. Ramdas Kanissery


*Spray Application Date – April 2, 2019

Summary:
This replicated study aimed to compare flumioxazin weed control with and without Hydrovant. Row middles commonly seen in fruit and vegetable crops in Florida in between raised beds were treated with flumioxazin. The same labeled rate of flumioxazin was applied alone and with Hydrovant at 0.1% v/v at U/Florida’s SWFREC research facility. The beds and middles were prepared per standard commercial growing operations and the soil type was sand.

Conclusion:
Results show that combining Chateau 51 WDG with Hydrovant at a rate of 0.1% resulted in significant efficacy gains in the final 60 days of the 120-day trial.

Improved Prowl Pre-Emerge Herbicide Weed Control

Replicated Trial – Weed Control Mixed with Prowl H2O / University of Florida, SWFREC Dr. Ramdas Kanissery


*Spray Application Date – April 2, 2019

Summary:
This data was part of a large, replicated pre-emerge herbicide trial. The objective of this part of the trial was to evaluate whether the addition of Hydrovant to Prowl H2O (pendimethalin) improved weed control. The same rate of Prowl H2O was sprayed on sandy soils at the U/Florida’s SWFREC research center with and without Hydrovant at 0.1% v/v.

Conclusion:
Results show that combining Prowl H2O with Hydrovant at a rate of 0.1% resulted in significant efficacy gains in the final 74 days of the 120-day trial.

Improved Spartan Pre-Emerge Herbicide Weed Control

Replicated Trial – Weed Control – Spartan Herbicide (Sulfentrazone) | University of Florida, SWFREC Dr. Ramdas Kanissery


*Spray Application Date – April 2, 2019

Summary: This data was part of a large, replicated pre-emerge herbicide trial. The objective of this part of the trial was to evaluate whether the addition of Hydrovant to Spartan herbicide improved weed control. The same rates of Spartan were sprayed on sandy soils at the U/Florida’s SWFREC research center with and without Hydrovant at 0.1% v/v.

Conclusion:
Results show that combining Spartan herbicide with Hydrovant at a rate of 0.1% resulted in significant efficacy gains in this trial.

Significant Increase in Weed Control

HYDROVANT-fA WEED CONTROL REPLICATED TRIAL
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.
