Abstract

The invention relates to a synergistic weeding composition containing clodinafop-propargyl. The composition is composed of the following active components: clodinafop-propargyl, carfentrazone-ethyl and MCPA-sodium (2-methyl-4-chloro-phenoxyacetic acid-sodium) that are in a weight ratio of 1-40:1-40:10-80. The composition can be prepared into wettable powder, water dispersible granules, oil-based suspensions, suspension emulsions, microemulsions, and emulsions in water. The weeding composition provided in the invention can be used for prevention and treatment of broadleaf weeds, gramineous weeds and cyperaceae weeds in corn field and wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition containing clodinafop-propargyl, which is used for preventing and controlling common weeds in corn fields and wheat fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can ...
