Abstract

The invention relates to a bactericidal composition. The effective components of the composition comprise (A) captan and (B) methoxyl acrylic ester bactericide comprising kresoxim-methyl, azoxystrobin, enestroburin, alkene oxime amine, and the like; the mass proportion of the A to the B is 50:1-1:50, preferably 20:1-1:20; and the balance is auxiliary components which are allowable to be used in pesticide and can be acceptable. The captan and the methoxyl acrylic ester bactericide after compounding have obvious synergy, and are mainly used for controlling diseases on crops such as cereals, fruit trees, vegetables, and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing captan and methoxyacrylate fungicides. Background technique [0002] In the actual process of agricultural production, chemical control is the main effective means of disease control. However, in recent years, many types of pathogenic bacteria have developed resistance to some frequently used pesticides, such as powdery mildew, spotted deciduous fungus, anthracnose and other plant pathogens. The problem of resistance to pesticides is very common and has become a major problem in chemical control. Due to the resistance of the bacteria, frequent application of pesticides, increased burden on farmers and increased environmental pollution. In areas where certain diseases occur seriously, conventional pesticides are difficult to prevent and control alone, and the effect is very poor. Therefore, there is an urgent need to find efficient, safe and environme...
