Fluazifop-P-butyl

Type: Herbicide

Mode of Action: Inhibiting the enzyme ACCase (acetyl-CoA carboxylase)

Common Product Names: Fusilade II & Fusilade DX

What is it?

Fluazifop-P-butyl is a selective post-emergent herbicide primarily used to control annual and perennial grass weeds in a variety of broadleaf crops, such as soybeans, cotton, and vegetables. It is absorbed by the foliage of the grass weeds and translocated throughout the plant, where it accumulates in the meristematic tissues (areas of active growth). Once there, it disrupts essential metabolic processes, ultimately killing the weed. Visible symptoms on treated grass weeds typically appear within 7-14 days after application, with complete weed control occurring within 2-4 weeks.

How does it work?

Fluazifop-P-butyl is absorbed by the leaves of target grass species. After absorption, it is translocated throughout the plant, concentrating in the actively growing regions, such as the shoot tips and root tips. By inhibiting the ACCase enzyme, it disrupts the synthesis of fatty acids, which are essential components of cell membranes and other cellular functions. This disruption leads to the cessation of growth and eventually the death of the weed.

Benefits

  • Selective Weed Control: Highly effective against grass weeds without harming broadleaf crops.
  • Post-Emergent Application: Targets weeds that have already germinated and are actively growing, allowing for precise control.
  • Systemic Action: The herbicide is translocated throughout the weed, ensuring complete kill, including the root system.
  • Flexible Use: Can be applied to a wide range of broadleaf crops, making it versatile in different agricultural settings.
  • Residual Control: Provides long-lasting control of grass weeds, reducing the need for frequent reapplication.
  • Compatibility: Can be tank-mixed with other herbicides for broader weed control.
