Medicinal composition containing amisulbrom, pesticide and application thereof

Abstract

The invention relates to the technical field of pesticides, and in particular relates to a medicinal composition containing amisulbrom. The medicinal composition comprises the following active ingredients by weight: 0.5-5 parts of pyraflufen-ethyl, 3-30 parts of the amisulbrom and 40 to 120 parts of a high fat film. In the active ingredients of the medicinal composition, the pyraflufen-ethyl playsa defoliation effect, and after application, the growth environment of cotton bolls in the middle and lower part of a cotton plant can be improved, and an environment which is not conducive to the infection and growth of pathogenic microorganisms can be created; the amisulbrom can effectively prevent the occurrence of cotton boll rot caused by oomycetes; the high fat film can effectively controlthe expansion of infected lesions and reduce the incidence of the cotton bolls infected by other weak pathogenic pathogens. After compounding of the pyraflufen-ethyl, the amisulbrom and the high fat film, by adjustment of the external environment of the cotton bolls and inhibition of the pathogen activity and the infection probability of the cotton boll rot, the development of the cotton boll rotcan be effectively controlled, and the incidence of the cotton bolls infected by other weak pathogenic pathogens can be reduced after the medicinal composition is applied in the initial stage of the cotton boll rot.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a medicament composition containing indazole sulfastrobin, pesticides and applications thereof. Background technique [0002] Cotton boll rot (Cotton Boll Rot) is a general term for diseases that occur on cotton bolls, mainly including blight, red rot, anthracnose, angular spot, black fruit, red powder and other diseases, and is an important disease in cotton production in my country. Cotton bolls generally begin to occur in the lower part of the cotton plant in August. In the early stage, the epidemic disease is the main disease. The occurrence and development of the epidemic disease can not only directly damage the cotton bolls, but also open the way for the invasion of other pathogenic bacteria, which can cause symptoms such as stiff valves and rot, which seriously affect the cotton bolls. Cotton quality and yield. The rate of rotten bolls can reach 100% in the year when b...
