Abstract

The invention discloses application of triazol pyridine derivative shown in formula (I) in preparing a monocotyledon-resistant pesticide. The triazol pyridine derivative has inhibiting effect on barnyard grass, green foxtail and crabgrass, and the inhibition rate on the barnyard grass, the green foxtail and the crabgrass is over 80%. A novel variety is provided for screening of monocotyledon-resistant pesticides; R in the formula (I) is C1-C4 alkyl or substituted phenyl, trifluoromethyl, pyridyl and hydrogen; and substituent on the substituted phenyl is alkyl, methoxyl and chlorine atoms.

Description

(1) Technical field [0001] The invention relates to the application of a triazolopyridine derivative in the preparation of anti-monocotyledonous medicine. (2) Background technology [0002] Among the newly developed pesticide compounds, about 90% of the pesticide species contain heterocyclic compounds, and nitrogen-containing heterocyclic rings account for the majority, which opens up a broad space for the development of pesticides. Nitrogen-containing heterocyclic compounds have little toxicity to warm-blooded animals, especially to birds and fish, and have excellent biological activities, such as super-efficient herbicidal activity, insecticidal activity, and bactericidal activity. Among the many nitrogen-containing heterocyclic compounds, triazole rings and pyridine rings are of great significance in the research and development of new pesticides because of their unique structural characteristics, excellent biological activity and low toxicity to the human body, and have ...
