- Avoid applications under drought stress or when plants are growing slowly
Lactofen FAQ - Common Questions Answered
FAQ Section 1: Application Questions
Q: What is the best time to apply Lactofen?
A: The optimal application window for Lactofen is when soybean plants have 1-3 trifoliate leaves and weeds are actively growing, typically 4-8 inches tall. Avoid applications during periods of extreme heat (above 90°F) or drought stress as this may increase crop injury potential.
Q: Can Lactofen be tank-mixed with other herbicides?
A: Yes, Lactofen can be effectively tank-mixed with glyphosate, clethodim, or sethoxydim for expanded weed control. Always conduct a jar test before mixing large quantities and follow all label recommendations regarding compatibility and application restrictions.
FAQ Section 2: Safety and Handling
Q: What personal protective equipment (PPE) is required when handling Lactofen?
A: Applicators should wear long-sleeved shirt and pants, chemical-resistant gloves, shoes plus socks, and protective eyewear. A NIOSH-approved respirator with organic vapor cartridge is recommended when mixing and loading in confined spaces or during prolonged exposure.
FAQ Section 3: Performance Factors
Q: How quickly does Lactofen work on weeds?
A: Lactofen typically shows visible effects on susceptible weeds within 24-48 hours after application, with complete control achieved within 7-14 days depending on environmental conditions. The rapid action is due to its contact activity and light-activated mechanism of action.
