Bactericidal composition and application thereof

Abstract

The invention relates to the technical field of pesticides, in particular to a bactericidal composition and application thereof. The effective components of the bactericidal composition provided by the invention are fluindapyr and meptyldinocap, and the mass ratio of fluindapyr to meptyldinocap is (6-10): (13-17). The invention also discloses an application of the bactericidal composition containing fluindapyr and meptyldinocap in prevention and treatment of diseases in crops. The fluindapyr and meptyldinocap are compounded, the fluindapyr and meptyldinocap can generate a synergistic effect, and the fluindapyr and meptyldinocap are prepared into the micro-capsule suspending agent taking the melamine formaldehyde resin as an encapsulating material, so that the formed bactericidal composition has a good sterilization effect, and particularly has a good prevention and treatment effect on the cherry tomato late blight. Compared with single dosages of fluindapyr and meptyldinocap, the bactericidal composition has the advantages of low dosage, low cost and low side effect, and does not influence the safety, the yield and the like of crops.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition and its application. Background technique [0002] In recent years, fungal diseases of the lower flagellar subphylum, represented by late blight, have occurred on a large scale and caused severe crop quality decline and yield reduction. Cherry tomato late blight is caused by Phytophthora infestans and occurs in cherry tomato diseases. Occurs throughout the growth period of the fruit, the adult stage is more susceptible, leaves, stems and fruit may be injured, leaves and green fruit are most severely damaged. Infected leaves are mostly in the lower part. Dark green irregular water-soaked lesions first appear on the edge or tip of the leaf, which expand and turn brown. The lesion area is large and the outline of the lesion is not obvious. Finally, the entire diseased leaf hangs from the petiole. In high humidity, sparse white mold can be seen on lea...
