Introduction | Post-emergence stem and leaf selective herbicide for soybeans. It has a broad spectrum of herbicides and a fast action, and can control amaranth, commelina, nightshade, amaranth retroflexus, pigweed, amaranth, piloseroot, cocklebur, and shepherd's purse in soybean fields. It is quickly absorbed by weed leaves after use, causing the leaves to turn yellow and quickly wither and die. Rainfall within 4-6 hours after spraying will not affect the weeding effect. |
Technical and Preparations | Original drug: 95%, 98%. Commonly used preparations: 10%, 20%, 25% emulsifiable concentrate; 25%, 48%, 250 g/L aqueous formulation; 12.8%, 20%, 30% microemulsion; 75% water-dispersible granules. |
Use type | herbicide |
Main targets & applications | Summer soybean annual broadleaf weeds, 187.5~225 g/hm2; spring soybean annual broadleaf weeds, 222~375 g/hm2 spray. |
The way of action | Selectivity |
Mode of action | Inhibit protoporphyrinogen oxidase (PPO) |
Resistance | International Herbicide Resistance Action Committee/Weed Science Society of America HRAC/WSSA Group 14 |
Toxicity and antidotes | China's pesticide toxicity classification: low toxicity. World Health Organization pesticide hazard classification: II (moderate hazard). Globally Harmonized System of Classification and Labeling of Chemicals (GHS) Acute toxicity hazard category of chemicals: 4 (harmful if swallowed). |
