Embodiment 1

[0033] In chemical control, use the fungicide spraying made of cloclostrobin, difenoconazole and difenoconazole as the active ingredients. 1g of ester, 5g of polyoxyethylene fatty alcohol ether, 20g of ethanol, 2g of resorcinol, 1g of propylene glycol, 1g of hydroxymethylcellulose, and 20g of water.

[0034] Mix Chloroprexate, Difenoconazole, Difenostrobin, Polyoxyethylene Fatty Alcohol Ether and Ethanol together to dissolve it into a homogeneous oil phase, add Resorcinol, Propylene Glycol, Carboxymethylcellulose Mix the element and water together to dissolve it into a uniform water phase, add the oil phase to the water phase while stirring at high speed in the reactor, add water slowly until the phase inversion point is reached, and turn on the shearing machine for high-speed shearing. Cut for 20-40 minutes to form an oil-in-water emulsion to obtain a fungicide. Dilute the fungicide with water 500-1000 times and spray.

Embodiment 2

[0036] In chemical control, fungicide spraying is made of the active ingredients of cloclostrobin, difenoconazole and difenoconazole. 3g of ester, 5g of polyoxyethylene fatty alcohol ether, 20g of ethanol, 2g of resorcinol, 1g of propylene glycol, 1g of hydroxymethylcellulose, and 20g of water.

[0037] See Example 1 for the preparation method and usage method.

Embodiment 3

[0039] In chemical control, use the fungicide spraying made of cloclostrobin, difenoconazole and difenoconazole as the active ingredients. 3g of ester, 5g of polyoxyethylene fatty alcohol ether, 20g of ethanol, 2g of resorcinol, 1g of propylene glycol, 1g of hydroxymethylcellulose, and 20g of water.

[0040] See Example 1 for the preparation method and usage method.

Abstract

The invention provides a preventing and treating method for the grape gummy stem blight for solving the problem that in the prior art, the use of more than ten kinds of bactericides causes high residue. The preventing and treating method for the gummy stem blight is carried out in the following manners: (1) soil ecological management; (2) agricultural prevention and treatment: additionally applying an organic fertilizer to promote grapes to grow robustly and improve the disease resistance of the plants; intensifying cultivation management and protecting branches and tendrils from various damages; doing field sanitation well, immediately removing hydrops and reducing the quantity of overwintering germs; (3) biological control; (4) biological prevention and treatment; (5) physical prevention and treatment; and (6) chemical prevention and treatment: preparing a bactericide from effective components: tricyclopyricarb, difenoconazole and 2-[2-(2,5-dimethyl-phenoxyl)-phenyl]-3-methoxylmethyl acrylate in a mass ratio of 1 to (2-5) to (1-3). According to the method provided by the invention, the bactericidal ability is strong, the active compounds are safe and efficient, the preparation is environmental-friendly, and the three components which are compounded have a synergistic effect and are free of cross-resistance.

Description

technical field [0001] The invention relates to the field of agricultural sterilization bureaus, in particular to a method for preventing and treating grape vine blight. Background technique [0002] Grape vine blight is also called vine cut disease. Mainly damage vines or new shoots. The base of the vine near the surface is susceptible to disease. The initial disease spot is reddish brown, slightly sunken, and then expands into a dark brown spot. In autumn, the epidermis of the diseased vines is longitudinally fissured and becomes filamentous, which is easy to break. There are many small black dots on the surface of the diseased part, which are the fruiting bodies of the fungus. Leaf margins are curled, new shoots are withered, and leaf veins, petioles and tendrils often have black streaks. [0003] Grape vine blight is an important disease of grapes. It is mainly distributed in the northwest grape producing areas, and also occurs in Henan, Shandong and other provinces....
