Abstract

The invention relates to a bactericidal composition containing active ester and dithianon. The effective components of the composition comprise active ester and dithianon, the weight ratio of active ester to dithianon is 1:80-60:1, and assistants can be added to the effective active components to prepare a wettable pulvis, a water dispersible granule, a suspension, a suspension emulsion, an emulsion in water, a microemulsion, a microcapsule suspension, and a microcapsule suspension-suspension. The composition can be used for controlling the rust disease, downy mildew, the mildew disease, scab, phytophthora blight, anthracnose, ring spot, brown patch, brown rot, leaf curl, shot hole, Alternaria Leaf Spot and leaf spot on rice, wheat, peaches, oranges, bananas, watermelons, pears, grapes, flours, capsicums, cucumbers and apples. The composition has the characteristics of wide bactericidal spectrum, small drug dose, rain wash resistance, and obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing activated ester and dicyanoanthraquinone on crop diseases. technical background [0002] Activated ester (Acibenzolar) chemical name: methyl 1,2,3-benzothiadiazole-7-thiocarboxylate, molecular formula: C 21 h 16 CIF 3 N 4 o 5 . Activated ester is a kind of plant disease resistance activator. It has no bactericidal activity and therapeutic effect, but it activates the plant's resistance mechanism after being absorbed by the plant, and activates the plant's own defense and resistance response, thus making the plant resistant to various Fungi, bacteria, nematodes and diseases develop broad-spectrum self-protection and long-lasting resistance. [0003] Dicyanoanthraquinone (dithianon) chemical name: 2,3-dicyano-1,4-dithioanthraquinone, molecular formula: C 14 h 4 N 2 o 2 S 2 . Dicyanoanthraquinone decomposes under al...
