Embodiment 1

[0049] According to parts by weight, take 0.5 parts of pyraclofen, 5 parts of pyraclostrobin, 25 parts of high-fat film, 5 parts of N-methyl fatty acyl taurate, 2 parts of cetyl betaine, 5 parts of White carbon black and 57.5 parts of kaolin were crushed to 325 mesh respectively, and then ground to a particle size of 0.044mm by a grinder, and mixed to obtain 25.5% wettable powder containing pyraclostrobin.

Embodiment 2

[0051] According to parts by weight, take 1 part of pyraclofen, 5 parts of pyraclostrobin, 35 parts of high-fat film, 5 parts of alkyl phosphate, 2 parts of sodium dinonyl phosphate, 5 parts of white carbon black and 47 parts of kaolin , the above-mentioned substances were crushed to 200 meshes, and then ground to a particle size of 0.035mm with a grinder, and after mixing, 41% wettable powder containing pyraclostrobin was obtained.

Embodiment 3

[0053] In parts by weight, take 0.5 parts of pyraclofen, 10 parts of pyraclostrobin, 50 parts of high-fat film, 5 parts of GY-D06, 2 parts of ammonium lauryl sulfate, 5 parts of white carbon black and 27.5 parts of kaolin , respectively pulverize the above substances to 400 meshes, and then grind to a particle size of 0.05mm with a grinder, and mix to obtain 60.5% wettable powder containing pyraclostrobin.

Abstract

The present invention relates to the technical field of pesticides, and specifically provides a pharmaceutical composition containing pyraclostrobin, which comprises the following active ingredients in parts by weight: 0.5-5 parts of pyraclostrobin, and 8-30 parts of pyraclostrobin And high lipid film 40 ~ 120 parts. Among the active substances of the medicament composition of the present invention, pyraclofen plays a role in defoliation, and after application, it can improve the growth environment of cotton bolls in the middle and lower parts of cotton plants, and create an environment that is not conducive to the infection and growth of pathogenic microorganisms; Pyroxystrobin can effectively prevent the occurrence of cotton boll disease caused by oomycetes; high lipid film can effectively control the expansion of infected lesions and reduce the probability of cotton bolls being infected by other weak pathogenic bacteria. The combination of the three can adjust the external environment of cotton bolls, inhibit the activity of pathogens of cotton boll disease and the probability of infection, and can effectively control the development of the disease and reduce the risk of cotton bolls being infected by other weak pathogenic bacteria after application at the initial stage of cotton boll disease. probability.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pharmaceutical composition containing pyraclostrobin, pesticides and applications. 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 boll disease...
