Weeding composition containing mesotrione and propanil

Abstract

The invention provides a weeding composition containing mesotrione and propanil, the active ingredients of the weeding composition comprise mesotrione and propanil, and the mass ratio of mesotrione to propanil is (0.1-10): (1-100); and preferably, the ratio is (0.1-10): (1-60). The weeding composition can be used for preventing and removing annual and partial perennial weeds in paddy fields, and has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition containing mesotrione and propanil and its application. Background technique [0002] In recent years, the resistance of weeds in rice fields has been increasing, and the need for weeding has increased. At the same time, the development of new compounds for pesticides requires high efficacy, high safety, and high selectivity, which is not only time-consuming, but also expensive and difficult. In this case, we can solve this problem by rationally compounding and combining the existing compounds. [0003] Mesotrione, also known as mesotrione, chemical name: 2-(4-methylsulfonyl)-2-nitrobenzoyl)cyclohexane-1,3-dione. Mesotrione, a triketone compound, is a preemergence and postemergence broad-spectrum selective herbicide capable of inhibiting hydroxyphenylpyruvate dioxygenase (HPPD), which can effectively control major broadleaf grasses and some Poaceae...

AI Technical Summary

Problems solved by technology

[0005] Long-term single use of herbicides is likely to cause serious resistance to weeds, thereby increasing the dosage of herbicides and causing pollution to the environment. It is a research and development hotspot to find a synergistic composition that can improve the weeding effect and reduce the dosage of active ingredients.

In the prior art, there is no relevant literature report on compounding mesotrione and propanil
