Emamectin benzoate-chlorfenapyr injection for preventing pine wilt disease

Abstract

The invention relates to an emamectin benzoate injection to prevent pine wilt disease, which is characterized in that, the components of the invention are 0.5% to 2% emamectin benzoate, 10% to 15% tween 80 or tween 60, 15% to 20% butyl glycol ether and 65% to 72% organic solvent; the components are arranged in an injection container; the percentage is mass percentage. The emamectin benzoate injection has the advantages that, compatibility composition is more reasonable and more pertinent; through proper surface-active material and addition agent, the conduction of emamectin benzoate in pines is easier, therefore pine wood nematode can be eliminated; the form of the pharmaceutical preparation is more reasonable and more scientific; the invention has convenient use and practicality; active substance is added; combined with injection, the invention has better killing effect.

Description

technical field [0001] The invention relates to an injection for preventing pine wood nematode disease. Background technique [0002] Pine xylophilus disease caused by pine xylophilus is a major disease of pine forests. The disease first became popular in Japan, causing a large number of pine forests in the country to die, causing a huge ecological disaster. my country began to develop the disease in Nanjing in 1983, and now it occurs on a large scale in the southern forest areas of the country, causing great harm. In order to curb the prevalence of pine wood nematode disease, plant pathologists and entomologists, forest protection workers and governments in various countries are trying to find ways to deal with it, but so far there is no targeted control method. [0003] The epidemic law of pine wood nematode disease is that in spring and summer every year, the vector insect (Pine Beetle) carrying the pathogenic nematode pine wood nematode (hereinafter referred to as the ...

AI Technical Summary

Problems solved by technology

The reason is that pine wood nematode is a kind of worm, not an arthropod. Whether emamectin benzoate can be used to prevent pine wood nematode disease is uncertain, and the preparation form is not suitable for killing pine wood nematode. The nematodes are in the branches. With spray, the drug cannot touch the pine wood nematode, the effect is very poor, and the substantive killing effect is not achieved; the components are also unreasonable, and there is no good solvent to cooperate with the surfactant. It is difficult to conduct in the pine body, so it is not used in the prevention of pine wood nematode; similar problems also exist in the Chinese patent that the patent application number is 200510011428.7, and
