Abstract

The invention relates to a bactericidal composition and a preparation method thereof. The bactericidal composition is characterized by containing a copper-containing agent and strobilurin, wherein the dosage of the copper-containing agent is 20-80 parts by weight and the dosage of the strobilurin is 1-30 parts by weight; the copper-containing agent is selected from at least one of the copper oxychloride, copper hydroxide, cuprous oxide, copper calcium sulphate, Bordeaux mixture and basic chrome sulphate; the strobilurin is selected from at least one of pyraclostrobin, azoxystrobin, fluoxastrobin, dimoxystrobin, kresoxim-methyl, picoxystrobin, enestroburin, fenaminstrobin, pyraclostrobin, phenylatestrobin, nitrobenzenestrobin, phenamacril, tricyclopyricarb, coumoxystrobin, pyrametostrobin and pyraoxystrobin. By adopting the bactericidal composition, the crop canker, the scab, the downy mildew, the angular spot, the epidemic disease and the gray mold can be simultaneously prevented and treated, particularly the red spider can be effectively prevented and killed; due to the synergistic effect of all components, the total controlling effect is greater than 80% and the drug resistance cannot be generated.

Description

technical field [0001] The invention relates to a plant fungicidal composition and a preparation method. Background technique [0002] During the growth and development of crops, they are vulnerable to various diseases and insect pests, which are seriously harmful. For a long time, chemical control has been the main and effective means of disease control. However, in recent years, single drug use and unscientific drug use have caused a variety of pathogenic bacteria to develop resistance to the currently used pesticides, such as canker, scab, downy mildew, angular spot, blight, gray mold, etc. Commonly, it has become a major problem in chemical control. Due to the resistance of bacteria, frequent application of pesticides has increased the burden on farmers and environmental pollution. In some areas where the disease has occurred seriously, the use of conventional pesticides alone has been unable to achieve satisfactory control effects, seriously affecting the benefits of ...
