Abstract

The invention relates to an insecticide for tea. The insecticide is prepared from the following ingredients: radix sophorae, Celastrus angulatus roots, red-knees herb, Azadiraelita indiea seeds, sodium alkylbenzenesulfonate, butyl glycidyl ether, alkyl carbonate, ascorbic acid and plant ash. The invention further discloses a preparation method of the insecticide for tea. The method comprises the steps of cleaning the radix sophorae, the Celastrus angulatus roots, the red-knees herb and the Azadiraelita indiea seeds, then, performing crushing, then, subjecting the powder to heated refluxing bytaking ethanol as a solvent, extracting effective ingredients, then, carrying out mixing with the sodium alkylbenzenesulfonate, the butyl glycidyl ether, the alkyl carbonate, the ascorbic acid and theplant ash, and carrying out uniform stirring, thereby obtaining the insecticide for tea. When in use, the insecticide is diluted by 200 to 500 times and then is sprayed around stems, leaves and rootsof the tea. The insecticide can be used for rapidly and effectively killing Empoasca vitis, Aleurocanthus spiniferus, tea aphids and pink tea rust mite of the tea and also has the advantages of no toxicity, harmlessness, no pollution and the like.

Description

technical field [0001] The invention relates to an insecticide and its preparation method and application, in particular to an insecticide for tea, its preparation method and application, and belongs to the field of pesticide processing. Background technique [0002] my country is a big tea-producing country with the largest planting area in the world. For convenience and speed, most tea farmers use insecticides, which are mainly a type of pesticides used to prevent agricultural pests. At present, organophosphorus insecticides are the most widely used insecticides with many kinds of products, ranking first in the output of insecticides. These insecticides are usually made by chemical synthesis, although they have The advantages of rapid insecticide, but the large amount of pesticide residues, long-term consumption of food that has been treated with such pesticides will cause chronic toxicity to the human body, posing a threat to the human living environment. In recent years...
