FAQ Section 1
Q: What crops can Quizalofop-P-ethyl Technical be used on?
A: Quizalofop-P-ethyl Technical is primarily used in broadleaf crops including soybeans, cotton, peanuts, sugar beets, oilseed rape, vegetables, and fruits. It provides excellent selectivity in these crops while effectively controlling grassy weeds.
Q: How does Quizalofop-P-ethyl Technical work?
A: Quizalofop-P-ethyl Technical inhibits acetyl-CoA carboxylase (ACCase), a key enzyme in fatty acid biosynthesis. This disruption prevents the formation of cell membranes in susceptible grass weeds, leading to growth inhibition and eventual plant death.
Application Recommendations
| Crop | Target Weeds | Application Rate | Growth Stage |
|---|---|---|---|
| Soybeans | Foxtail, Barnyardgrass | 50-100 g ai/ha | 2-4 leaf stage of weeds |
| Cotton | Johnsongrass, Crabgrass | 60-120 g ai/ha | Post-emergence |
| Oilseed Rape | Wild oats, Ryegrass | 50-75 g ai/ha | 2-6 leaf stage |
FAQ Section 2
Q: What is the rainfast period for Quizalofop-P-ethyl Technical?
A: Quizalofop-P-ethyl Technical requires approximately 2 hours for adequate absorption after application. Rainfall occurring within this period may reduce effectiveness. For optimal results, apply when rain is not expected within 4-6 hours.
Q: Can Quizalofop-P-ethyl Technical be tank-mixed with other herbicides?
A: Yes, Quizalofop-P-ethyl Technical can be tank-mixed with many broadleaf herbicides. However, compatibility tests should be conducted before large-scale mixing. Avoid mixtures with strongly alkaline products as they may reduce efficacy.
