Problems solved by technology

[0013] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the emergence of pest resistance
Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution.

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to an ultra-low volume liquid containing cycloxaprid and a carbamate pesticide. According to the ultra-low volume liquid, cycloxaprid and the carbamate pesticide are compounded to form an active component, and other components are a surface active agent and a solvent; and the carbamate pesticide is one of carbosulfan, fenobucarb, triazamate, tsumacide, methomyl and thiodicarb. The ultra-low volume liquid is convenient to process and has long duration of efficacy and high work efficiency, a target has low probability of drug resistance, the environment pollution is little, pesticide and water are saved, the pesticide utilization rate is increased, and through ultra-low volume spray, low volume spray or ultra-low volume electrostatic spray, various pests of rice, wheat, corn, vegetable, tobacco, tea trees, fruit trees and sugar canes can be controlled.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an ultra-low volume liquid containing cyclopyrid and carbamate insecticides. Background technique [0002] Cyclopyrid is a new generation of ultra-high activity and ultra-low toxicity agricultural insecticide researched and developed by East China University of Science and Technology. Chemical name: 9-((6-chloropyridin-3-yl)methyl)-4-nitro-8-oxa-10,11-dihydroimidazo(2,3-a)bicyclo(3,2 ,1) Oct-3-ene, English common name: cycloxaprid, chemical molecular formula C14H15ClN4O3, chemical structural formula is: [0003] [0004] Cyclopyrid has systemic, stomach poisoning and contact killing activities on pests, and can be used to control Homoptera, Coleoptera and Lepidoptera pests on crops. Cyclopyrid has a novel mechanism of action, and studies have shown that when the dosage of cyclopyrid is lower than 10uM, it does not show agonist response to nicotinic acetylcholine receptors...
