Abstract

The present invention discloses a compound weed-killing preparation using pretilachlor and isoproturon as effective component. It is a wettable powder preparation, in which the pretilachlor content is 10%-60% and the isoproturon content is 10%-60%. Said compound weed-killing preparation also contains other adjuvant and filling material.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a compound herbicide preparation with pretilachlor and isoproturon as active ingredients. Background technique [0002] Isoproturon substituted urea selective pre-emergence and post-emergence herbicides for upland fields. It is mainly absorbed by the roots of weeds, less absorbed by the stems and leaves, and the water in the ducts is conducted upwards to the leaves. It is mostly distributed on the tip and edge of the leaves, and plays a role in the green cells. It is an inhibitor of light and electron transfer, and interferes with photosynthesis. Under the light, oxygen and carbon dioxide cannot be released, the formation of organic matter stops, and sensitive weeds die due to starvation. Sufficient sunlight, high temperature, and high soil humidity are conducive to the efficacy of the medicine, and the efficacy of the medicine is poor during drought. After spraying, the tips and edge...
