Abstract

The invention relates to a botanical pesticide, particularly to a plant extract composition for preventing and treating apple tree canker and a preparation method thereof. The plant extract composition solves the problems of single material, ideal effect and the like of the existing pesticide for preventing and treating apple tree canker. The plant extract composition is composed of 0.5 to 1.5 parts of kuh-seng fruits, 1 to 3 parts of radix sophorae flavescentis fruits, 0.5 to 1.5 parts of melia toosendan fruits, 0.3 to 0.7 parts of euphorbia fischeriana roots, and 0.2 to 0.4 parts of tobaccos. With repeated testings, the technical scheme provides a novel botanical pesticide with high effect, low toxicity, low residue and environment friendliness. The botanical pesticide has profound significances for protecting environment, avoiding the apple tree canker as a devastating disease in growth of the apple tree and reducing arsenic content in the soil.

Description

technical field [0001] The invention relates to a botanical pesticide, in particular to a combination of plant extracts for preventing and treating apple tree rot and a preparation method. Background technique [0002] Apple rot is a destructive disease that occurs in serious orchards, with scarred trees, incomplete branches, and even dead trees and garden damage. According to the survey, the average incidence rate of young trees aged 2-3 is 9.5%, that of trees aged 4-10 is 14.1%, that of trees aged over 10 years is 23%, and is as high as 51.4%. For a long time, domestic control of apple rot has mainly used chemical agents, among which thiram series thiram is the main agent. Although the effect is relatively ideal, continuous use will increase the content of arsenic in various parts of the fruit tree and in the orchard soil to varying degrees. It even causes dead bark and dead trees to occur in the tree body. Therefore, in 2002, the country has banned the use of thiram. T...
