Abstract

The invention provides a pesticide film forming agent used for controlling diseases and insect pests of forest trees, and its preparation method. The pesticide film forming agent comprises 0.5-10% of an active component, 0.5-10% of a film forming aid, 5-15% of a solvent, 5-15% of an aid and 50-80% of water; and the active component is one of or a mixture comprising several of tebuconazole, difenoconazole, propiconazole and emamectin benzoate. The drug film forming agent has a good control effect on the diseases and insect pests of the forest trees, has a low price, is convenient to use, and has a good control effect on the dry rot diseases of hickory trees, the canker of various trees, stalk longhorn beetles and bark beetles, leaf aphids, red spider mites and the like especially; the drug film forming agent reduces the active component volatilization and loss possibility and changes the release performance, so the residual period is prolonged, the drug dose and the dosing frequency are reduced; and the drug film forming agent reduces the toxicity of highly toxic pesticides, reduces the acute toxicity of pesticides, reduces the drift of the pesticides, and mitigates the pollution to the environment and the hazard to crops.

Description

technical field [0001] The invention relates to the technical field of preventing and controlling forest diseases and insect pests, in particular to a pesticide film-forming agent for preventing and controlling forest diseases and insect pests. Background technique [0002] my country is one of the countries where forestry pests occur and cause the most serious harm. During the "Eleventh Five-Year Plan" period, the average annual occurrence area of ​​forestry pests is 170 million mu, and there are 295 main types of forestry pests. According to the data recorded by the State Forestry Administration, more than 40 million trees are killed each year due to forest diseases and insect pests in my country, causing an average annual loss of 11 million More than 100 million yuan. In 2010 and 2011, the average annual area of ​​moderate and severe occurrence of forestry pests across the country was 53 million mu, accounting for 59% of the afforestation area in the same period. In rece...
