Picoxystrobin and prochloraz containing sterilization composition and application thereof

Abstract

The invention discloses a picoxystrobin and prochloraz containing sterilization composition and application thereof. The sterilization composition employs picoxystrobin and prochloraz as main active components, wherein the weight ratio of picoxystrobin and prochloraz is 1-90:1-90. The sterilization composition is applicable to control on diseases of cereal, fruit trees and vegetables, has relatively high synergistic effect, helps to overcome and delay drug resistance of pathogens, is fast in sterilization speed and long in persistent period, helps to reduce application cost, and has obviously more excellent control effect than the control effect when picoxystrobin and prochloraz are respectively independently used. The sterilization composition provided by the invention is applicable to control on fungal diseases of crops, especially applicable to control on fungal diseases such as powdery mildew, rust disease, septorianodorum, net blotch, bakanae disease, anthracnose, epidemic disease, brown patch, leaf spot disease and the like, and has relatively good effect than the effect when picoxystrobin and prochloraz are respectively independently used.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with picoxystrobin and prochloraz as main active ingredients and its application. Background technique [0002] Picoxystrobin, chemical name: (E)-3-methoxy-2-{2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl}methyl acrylate, Molecular formula: C 18 h 16 f 3 NO 4 . The structural formula is as follows: [0003] [0004] Mechanism and characteristics: Mitochondrial respiration inhibitor, that is, to inhibit mitochondrial respiration through electron transfer between cytochrome b and C1. It is effective in controlling strains resistant to 14-demethylase inhibitors, benzamides, tricarboxamides and benzimidazoles. Once taken up by the leaves, picoxystrobin moves in the xylem, following the water flow in the transport system; it also flows in the gas phase on the leaf surface and flows in the xylem after being absorbed into the leave...

AI Technical Summary

Problems solved by technology

[0008] 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
