Fruit tree biopesticide

Abstract

Belonging to fruit tree pesticides, the invention discloses a fruit tree biopesticide, and aims to provide a pollution-free fruit tree pesticide without residue. The biopesticide is prepared from fresh red capsicum annuum, garlic, sodium carbonate and water in a weight ratio of 10:7:3:100. The method includes: pulping fresh red capsicum annuum, mashing garlic into mashed garlic, then mixing the substances with water evenly, conducting standing for 10-12h, adding sodium carbonate into filtrate, and mixing the materials evenly.

Description

technical field [0001] The invention relates to an insecticide for fruit trees, in particular to a biological insecticide for fruit trees; it belongs to insecticides. Background technique [0002] As we all know, when apples enter the expansion period, it coincides with the high temperature and rainy weather in the middle and late July. While promoting fruit expansion, it is also very conducive to the spread of diseases and insect pests. Repeated infection, occurrence and prevalence of early leaf defoliation, ring spot, anthracnose and other diseases; the formation of the bark layer of apple trees is the right time for the invasion of rot disease bacteria, and the disease begins a new round of infection and disease; peach borer The first-generation eggs hatch and bore fruit; pests such as spider mites, aphids, and leaf tortrixes are mixed in different stages in the field, and the damage is aggravated. Therefore, it is of great significance to do a good job in the prevention...

AI Technical Summary

Problems solved by technology

However, the application of chemical pesticides during the fruit expansion period is likely to pollute the fruit, cause pesticide residues, and endanger health. Moreover, long-term use will also cause insecticide resistance, which will eventually lead to a decrease in the insecticidal effect and aggravation of insect damage.
