Lactofen

Lactofen is the ISO common name for an herbicide belonging to the diphenyl ether class. It is used primarily as a post-emergent herbicide to control broadleaf weeds in various crops, including soybeans, peanuts, and cotton.

Mechanism of Action:

Lactofen works by inhibiting the enzyme protoporphyrinogen oxidase (PPO), also known as PROTOX. PPO is essential for the synthesis of chlorophyll in plants. Inhibition of PPO leads to a buildup of protoporphyrinogen IX, which, when exposed to light, generates highly reactive oxygen species (singlet oxygen). These reactive oxygen species cause rapid cell membrane disruption and ultimately plant death.

Use and Application:

Lactofen is typically applied as a foliar spray. The application rate and timing depend on factors such as the crop, target weed species, and environmental conditions. It is important to follow label instructions carefully when using lactofen to ensure effective weed control and minimize the risk of crop injury or environmental impact.

Environmental Fate:

Lactofen's persistence in the environment depends on factors such as soil type, temperature, and moisture. It generally has a relatively short half-life in soil.

Safety and Regulatory Information:

Lactofen is regulated by governmental agencies in various countries, including the United States Environmental Protection Agency (EPA). These agencies establish maximum residue limits (MRLs) for lactofen in food and crops to ensure consumer safety. Safety data sheets (SDS) provide detailed information on the handling, storage, and potential hazards associated with lactofen.
