AI Technical Summary

⚠Technical Problem

Herbicides used alone in existing farmland can easily lead to weed resistance and have a single herbicidal effect, making it difficult to effectively control multiple weeds at the same time. Especially in rice areas, there are problems with excessive application times and dosages.

⚗Method used

Three herbicides, nicosulfuron-methyl, ametrione and dimethyltetrachloroisooctyl, are compounded according to a specific mass ratio to form a dispersible oil suspension. Their different mechanisms of action are used to achieve synergistic effects and expand Improve herbicidal spectrum and delay the development of resistance.

🎯Benefits of technology

It significantly improves the weeding effect, reduces the cost of medication and environmental pollution, extends the service life of the agent, ensures the safety of crops, and reduces the number of medication applications.

Abstract

The invention discloses a nicosulfuron-containing herbicidal composition and application thereof. The herbicidal composition is prepared from the following components: nicosulfuron, amicarbazone, and dimethyltetrachloroisooctyl ester as well as a dispersant, an emulsifier, a wetting agent, a thickening agent, an antifreeze, and a dispersion medium, wherein the dosage form belongs to a dispersed oil suspension agent. Through the combination of the three active ingredients, the herbicidal composition has an obvious synergistic effect, the use amount of pesticides is reduced, the cost and environmental pollution are reduced, the drug resistance of corn field weeds can be delayed by the application of the composition, and the control spectrum is expanded.
