Bactericidal composition containing azoxystrobin and fenaminstrobin

Abstract

The invention discloses a bactericidal composition containing azoxystrobin and fenaminstrobin and application thereof. The bactericidal composition uses the azoxystrobin and the fenaminstrobin as main effective ingredients, wherein the mass ratio of the azoxystrobin to the fenaminstrobin is (70:1) to (1:50). The bactericidal composition can be applied to prevention and control of cereal, fruit tree and vegetable diseases, has a higher synergistic interaction effect, overcomes and delays the drug resistance of pathogenic bacteria and is high in sterilization speed and long in lasting period, the application cost is reduced, and a prevention and control effect is obviously superior to the effects of single chemical pesticides in use. The bactericidal composition can be used for preventing and controlling fungous diseases of crops, especially can be used for preventing and controlling powdery mildew, wheat glume blotch, wheat rust, wheat powdery mildew, rice sheath blight disease, powdery mildew of cucumbers, downy mildew of cucumbers, plasmopara viticola, apple powdery mildew, tomato early blight, pear scab and other fungal diseases and is better than the single chemical pesticides in effect in use.

Description

[0001] Technical field: [0002] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxastrobin and enoxastrobin as main active ingredients and its application. Background technique [0003] Fluoxastrobin (Fluoxastrobin) is a mitochondrial respiration inhibitor. Its mechanism of action is to inhibit mitochondrial respiration through electron transfer between cytochrome b and C1. Good compatibility and appropriate processing can further improve its penetration into the leaves through the cuticle. Although it has poor absorption capacity through seeds and roots, when used as a seed treatment agent, it has good killing and persistent effects on seedlings and seed-borne and soil-borne diseases, and it has a good effect on almost all fungi (Ascomycetes). , Basidiomycetes, Oomycetes and Deuteromycetes) diseases such as rust, glume blight, net spot, powdery mildew, downy mildew and other dozens of diseases have...

Problems solved by technology

[0005] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge
