Herbicide Fl is a selective herbicide designed to control a wide range of broadleaf weeds in various crops, including corn, soybeans, and wheat. The active ingredient in Herbicide Fl is flumetsulam, a triazolopyrimidine sulfonamide herbicide that works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for plant growth and development. This comprehensive manual will provide detailed information on the usage, application, and safety precautions of Herbicide Fl.
Product Description and Specifications
Herbicide Fl is a water-soluble liquid formulation that contains 30% flumetsulam by weight. It is available in various package sizes, including 1-gallon and 2.5-gallon jugs. The product has a low viscosity and high water solubility, making it easy to mix and apply. Herbicide Fl is compatible with a wide range of adjuvants and fertilizers, allowing for flexible application options.
Mode of Action and Weed Control Spectrum
Herbicide Fl controls weeds by inhibiting the ALS enzyme, which is involved in the synthesis of branched-chain amino acids. This leads to a rapid cessation of plant growth and eventual death of the weed. The product is effective against a broad range of broadleaf weeds, including common lambsquarters, velvetleaf, and morningglory. It is also effective against certain grassy weeds, such as crabgrass and foxtail.
| Weed Species | Control Rating |
|---|---|
| Common lambsquarters | Excellent |
| Velvetleaf | Excellent |
| Morningglory | Good |
| Crabgrass | Good |
| Foxtail | Fair |
Application Instructions and Rates
Herbicide Fl can be applied pre-emergence or post-emergence, depending on the crop and weed species. The recommended application rate ranges from 0.25 to 0.5 oz/A, depending on the specific use pattern. It is essential to follow the label instructions and take note of the maximum seasonal use rate to avoid crop injury or residue issues.
Pre-Emergence Application
For pre-emergence applications, Herbicide Fl should be applied within 3 days of planting, prior to weed emergence. This application timing provides excellent control of early-emerging weeds and helps to reduce weed competition during the critical crop establishment phase.
Post-Emergence Application
For post-emergence applications, Herbicide Fl should be applied when weeds are less than 4 inches tall. This application timing provides effective control of emerged weeds and helps to prevent seed production.
What is the recommended application rate for Herbicide Fl in corn?
+The recommended application rate for Herbicide Fl in corn is 0.25 to 0.375 oz/A, depending on the specific use pattern and weed species.
Can Herbicide Fl be applied with other herbicides or fertilizers?
+Yes, Herbicide Fl can be applied with other herbicides or fertilizers, but it is essential to follow the label instructions and take note of any compatibility restrictions or recommended use rates.
Safety Precautions and Environmental Considerations
Herbicide Fl is a relatively low-toxicity herbicide, but it is still essential to follow the label instructions and take necessary safety precautions to minimize exposure. The product should be applied in a well-ventilated area, and applicators should wear protective clothing, including gloves, long sleeves, and eye protection.
Environmental Fate and Transport
Herbicide Fl is moderately mobile in soil and may leach into groundwater under certain conditions. It is essential to follow the label instructions and take necessary precautions to minimize environmental exposure, including avoiding applications near water sources or areas with high water tables.
In conclusion, Herbicide Fl is a selective herbicide that provides effective control of a wide range of broadleaf weeds in various crops. By following the label instructions, taking necessary safety precautions, and considering environmental factors, growers can minimize risks and maximize benefits from using this product.
