Sterilizing and disease preventing suspended seed coating and application

Abstract

The invention belongs to the field of pesticide, and relates to a sterilizing and disease preventing suspended seed coating and application, in particular to a sterilizing and disease preventing suspended seed coating formed based on azoxystrobin, fludioxonil and metalaxyl-M and application. The sterilizing and disease preventing suspended seed coating is prepared from an original medicine A, an original medicine B and an original medicine C according to the weight proportion of (0.5-4):(4-8):(10-14). The original medicine A is a fludioxonil original medicine; the original medicine B is a metalaxyl-M original medicine; the original medicine C is an azoxystrobin original medicine. The sterilizing and disease preventing suspended seed coating wide in bacteriocidal spectrum, low in effective ingredient use amount and capable of effectively relieving and treating resistance and application are provided.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a bactericidal and disease-preventing suspension seed coating agent and its application, in particular to a bactericidal and disease-preventing suspension seed coating agent based on azoxystrobin, fludioxonil and mefenaxyl and its application. Background technique [0002] Azoxystrobin is a new, highly effective, broad-spectrum, systemic methoxyacrylate fungicide, which can be used for stem and leaf spray or seed treatment, and can also be used for soil treatment. It has a good effect on almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes), such as powdery mildew, rust, glume blight, net spot, downy mildew, rice blast, etc. activity, and no cross-resistance with existing fungicides. It is used in cereals, rice, grapes, potatoes, vegetables, fruit trees and other crops and is safe for these crops. [0003] Metalaxyl belongs to phenylamides. It is a broad...

AI Technical Summary

Problems solved by technology

[0007] 1) The combination of the two, the dosage is relatively high, it is easier to produce resistance, and it wastes resources;

[0008] 2) The action spectrum is narrow and the control range is small;

[0009] 3) The effect is relatively poor;

[0010] 4) Some of the non-seed treatment agents compounded by the two have a short duration of effect, and the drug effect is easily affected by the environment such as high temperature and rainfall.
