Method for preventing and controlling fruit and forest tree diseases and insect pests by dry method in medicine bag

Abstract

The invention relates to a method for preventing and controlling fruit tree and tree diseases and insect pests by using a medicine bag dry method. The principle is: make the medicine liquid penetrate into the xylem conduit of the tree, diffuse into the transpiration flow and evenly transport it to the leaves of the tree crown, so as to prevent and control the crown and tree leaves. For pests and diseases on the trunk, the implementation steps are: ① At the base of the trunk, scrape off the old skin and warped skin with a scraper to form a ring-shaped belt with a width of 15-20 cm; The proportion of the appropriate liquid medicine is prepared; ③ select a long strip medicine bag with strong adsorption force, pour the medicine liquid evenly on it, make it absorb enough medicine liquid, and stick the medicine bag close to the ring shape of the trunk. Put it on and wrap it in a circle; ④Wrap the medicine bag and the trunk tightly with plastic film tape from top to bottom, untie it after one and a half months, and then effectively achieve the purpose of preventing and controlling pests and diseases. The method for preventing and controlling the diseases and insect pests of fruit trees and forest trees not only has a good control effect, but also saves labor and cost, has long-lasting efficacy and is not affected by weather changes.

Description

technical field [0001] The invention relates to a method for preventing and controlling fruit tree diseases and insect pests, in particular to a method for preventing and controlling fruit tree and forest tree diseases and insect pests by using a medicine bag dry method. Background technique [0002] At present, crown spraying is commonly used to prevent tree diseases and insect pests. Due to the tall crown and dense leaves, it is not only difficult to operate, but also difficult to spray evenly and thoroughly. The control effect is often not ideal, which seriously affects the growth and yield of fruit trees. Contents of the invention [0003] In order to solve the problem that the effect of the traditional spraying method on preventing and controlling tree diseases and insect pests is not ideal, the present invention proposes a method of preventing and controlling fruit and forest diseases and insect pests by using the medicine bag dry method. It not only has a good contr...
