Embodiment 1

[0029] The preparation of embodiment 1 compound emulsifiable concentrate

[0030] 50% chlorothalonil EC (1:12): 4.01 parts of 96% chlorothalonil, 50.17 parts of 92% chlorothalonil, 10 parts of OP emulsifier, 35.82 parts of xylene. Put most of the solvent into the preparation kettle first, and then put the original drug, emulsifier and remaining solvent in order under stirring. In order to speed up the dissolution, it can be heated appropriately. After the original drug is completely dissolved, stop heating, and enter the Filtration process to get the finished product.

Embodiment 2

[0031] The preparation of embodiment 2 composite water suspension concentrate

[0032] 30% difenoconazole · chlorothalonil water suspension concentrate (1:5): Take 5.26 parts of 95% difenoconazole and 27.17 parts of 92% chlorothalonil, add 4 parts of ethylene glycol monobutyl ether, silicon 3 parts of magnesium aluminum acid powder, 10 parts of mixture of polyoxyethyl alkyl ether, nonylphenol polyoxyethylene ether and sodium alkylbenzene sulfonate, 50.57 parts of water. After the ingredients are mixed, they are mixed and pulverized by a ball mill, and then put into a sand mill for pulverization to obtain the finished product.

Embodiment 3

[0033] The preparation of embodiment 3 compound dry suspensions

[0034] 50% phenoxystrobin · chlorothalonil dry suspension (1:11): take 4.33 parts of 96.21% phenoxystrobin, 49.82 parts of 92% chlorothalonil, add 40.85 parts of nitrous acid pulp waste liquid (calculated as solid matter) parts, 5 parts of OP emulsifier. After mixing and dispersing the original drug, pulp concentrate and auxiliary agent, it is dried by a drum, coarsely pulverized, and then packaged.

Abstract

The invention relates to a pesticide for preventing vegetable anthrax, wherein the invention comprises active component, stuff and agent; the active component is formed by methyl acrylate pesticide or triazole pesticide and protector. The invention has 91. 42% effect, with low cost.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound fungicide for preventing and treating fruit and vegetable anthracnose. Background technique [0002] Anthracnose is an important disease in the production of fruit trees and vegetables. When the conditions are suitable, it will be serious, causing the plants to die or the fruits to rot. In my country, due to the annual cultivation of fruit trees and vegetables, the source of anthracnose bacteria has been continuously accumulated, which has a tendency to increase year by year, and has constituted a serious threat to its normal production. At present, there are few research reports on anthrax. The prevention and control of anthrax in production mainly relies on the benzimidazoles such as carbendazim and thiophanate-methyl. However, the long-term use of a single agent can easily lead to drug resistance. Induced resistance of plants can also reduce the damage of diseases, but it...
