Abstract
The invention belongs to the technical field of pesticide preparations, and particularly relates to a flonicamid-containing pesticide composition and application thereof. Multiple indoor and outdoor bioassay tests show that the pesticide composition provided by the invention has an obvious synergistic effect, and the control effect on the virus diseases on crops is remarkably improved by controlling vector insects which propagate the virus diseases and the synergistic effect on the treatment of the virus diseases.
Description
Technical Field
The invention belongs to the technical field of pesticide preparations, and particularly relates to a pesticide composition containing flonicamid and application thereof.
Background
Plant virus diseases are called plant cancer, which form serious threats to the yield and quality of food crops, garden crops, medicinal materials and the like worldwide for a long time, the yield is reduced by 10-30% each year, and the economic loss is about 200 hundred million dollars. China is a big agricultural country, and economic losses caused by virus diseases to grain crops, garden crops, economic crops and the like are about billions of yuan each year. Because the epidemic of the virus disease is mainly caused by the virus-carrying insects such as aphid, leafhopper, plant hopper, whitefly and other virus-carrying vector insects, the single medicament for preventing and treating the virus disease has not ideal prevention and treatment effect and can not fundamentally control the virus disease on crops.
Flonicamid is a novel low-toxicity pyridylamide pesticide and has the effects of contact poisoning and stomach poisoning. After sucking plant juice with flonicamid, aphids and other sucking mouth parts are sucked, juice sucking is rapidly stopped, no excrement appears within 1 hour, and finally death is caused by hunger. It can permeate from root to stem and leaf, but the permeation from leaf to stem and root is relatively weak, so that it has high safety to human body, livestock and environment.
Copper hydroxide is one of the oldest varieties of fungicides. The bactericidal activity of copper preparations (mainly copper sulfate) is discovered as early as 1807, and the copper preparations have obvious effects on preventing and controlling fungi and bacterial diseases, particularly bacterial diseases, and are widely applied to agricultural production. The copper bactericide is a multi-site action mechanism, and is mainly chelated with amino acid with-SH in pathogenic bacteria to denature the pathogenic bacteria so as to hinder and inhibit metabolism to cause death of the pathogenic bacteria. These amino acids are necessary for pathogenic bacteria and are multi-site, so that resistance is not easy to occur.
The research on the compounding of the flonicamid and the copper hydroxide is less, and the compounding of the flonicamid and the copper hydroxide is really not available for practical application.
