Novel oxime derivative and application thereof in agriculture

Abstract

The present invention relates to a novel oxime derivative and application thereof in agriculture. The novel oxime derivative has a structure represented by formula (I), wherein R<1>, R<2>, R<3>, R<4> and R<5> are each independently hydrogen, fluorine, chlorine or the like, A is shown as the specification, wherein R<11> and R<12> are each independently hydrogen, C1-4 alkyl group, phenyl group or the like, R is C1-4 alkoxy group or the like, and R is hydrogen or C1-4 alkyl group. The novel oxime derivative disclosed by the invention is novel in structure and simple in synthesis process, and has an excellent control effect on plant diseases, particularly cucumber downy mildew.

Description

Technical field[0001]The present invention relates to the field of pesticide fungicides, and in particular, the present invention relates to a novel derivative and its preparation method thereof and its application in agriculture as a fungicide.Background technique[0002]Plant fungal disease has always been one of the constraints in the growth and storage of food crops, affecting the development, nutritional value, and shelf life of the product. At present, the prevention and treatment of plant disease is mainly based on the use of chemical pesticides. Because of its small amount, it is favored by people, but because farmers use drug technology, it is not allowed to pursue the effect of the effect, leading to "resistance , Rampant, pesticide residue, etc., etc., etc. The problem is becoming more and more serious, so research and development can effectively control the efficient, low-toxic, low-residual new pesticides of hazardous organisms, have become the primary goal of current pes...

AI Technical Summary

Problems solved by technology

At present, the prevention and control of plant diseases mainly depends on the use of chemical pesticides, which are favored by people because of their small dosage and quick results. , more rampant, pesticide residues" and other problems are becoming more and more serious, so the research and development of new pesticides with high efficiency, low toxicity and low residue that can effectively control harmful organisms has become the primary goal of pesticide creation
