example 1

[0064] Example 1: In the most serious year of agricultural pests in the country, aphids and borers were rampant, coupled with drought, high temperature and no rain, aphids reproduced rapidly and the damage was rampant, especially on fruit trees, wheat, tea, pepper, corn, and cotton, such as: 3,000 mu of peach trees in Zhiyang Town, Shousi San Village, and Dongxizhao Village, Hancheng City, Shaanxi Province were severely damaged. The majority of fruit farmers sprayed pesticides almost every day to no effect. Almost all insecticides used could not control the pests. Under the situation that the fruit grower is at a loss, the applicant uses the botanical insecticide of embodiment 1 to test, after adopting two 300-fold dilutions, the disease and pest situation has been controlled, and continues to use the botanical insecticide 350 times, continuously After spraying 2-3 times, the fruit trees regained their vitality and reduced the losses caused by pests. The test results were prais...

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a botanical insecticide preparation and a preparation method thereof. Background technique [0002] At present, in the field of pesticides in our country, the insecticides used for a long time are mainly various chemical synthetic preparations, and there are a series of problems that are difficult to eliminate, such as polluting the environment, destroying ecological balance, and affecting the soil structure and water quality. The enrichment of pesticide and pesticide residues cannot guarantee the "food safety" of food and agricultural products, and further endangers human health and human living environment and other major issues. The pollution and harm caused by chemical pesticides in agricultural production have cost our national economy a high price, and have restricted the development of modern ecology and green organic agricultural land. Therefore, it is very...
