Lactofen
Type: Herbicide
Mode of Action: Inhibiting the enzyme protoporphyrinogen oxidase (PPO)
Common Product Names: Cobra & Boa
What is it?
Lactofen is a post-emergent herbicide primarily used in soybean, cotton, and peanut crops to manage a variety of broadleaf weeds. Its chemical formula is C17H11ClF3NO7, and it is known for its rapid action and effectiveness. Due to its specific mode of action, lactofen is a valuable tool for managing herbicide-resistant weed populations.
How does it work?
Once applied, lactofen is absorbed by the plant's foliage. It inhibits the PPO enzyme, disrupting chlorophyll synthesis and causing oxidative stress within the plant cells. This results in the formation of toxic compounds that damage cell membranes, leading to the rapid death of the targeted weeds. Visible effects can often be seen within hours of application, with complete weed control achieved within a few days.
