Problems solved by technology

[0006]Chemical methods are mainly used to prevent and control diseases caused by these pathogenic bacteria, but the biggest problem in chemical control at present is the single chemical agent, which is likely to cause bacterial resistance and weaken the control effect Even completely ineffective, so it is urgent to develop new control agents

Abstract

The present invention mainly provides a hydroxylamine compound and its preparation method which have inhibitory effects on Fusarium oxysporum, Fusarium moniliforme, Fusarium solani and anthracnose. Its chemical structural formula is: The plant disease caused by Fusarium oxysporum, Fusarium moniliforme, Fusarium solani and Anthracnose provides a new way, and the preparation method is simple, convenient and operable.

Description

【Technical field】 [0001] The invention relates to a compound and a preparation method thereof, in particular to a hydroxylamine compound and a preparation method thereof. 【Background technique】 [0002] Fusarium moniliforme is an important plant pathogen that can infect more than a dozen families of plants and cause many important diseases, such as corn seedling blight, ear rot, cotton red rot and rice bakanae disease, etc. And it can produce fumonisin to contaminate cereal products, causing livestock and human poisoning. [0003] Solanum disease Fusarium solani (Fusarium solani) causes root rot in eggplant, pea, Satawan, alfalfa, gerbera, saffron, and Phalaenopsis, causing serious damage. [0004] Anthracnose (Colletotrichum) is an important class of plant pathogenic fungi, widely distributed in tropical, subtropical and temperate regions, can cause many plant diseases, especially harmful to timber forests, special economic forests, seedlings and fruit trees. my country i...
