Problems solved by technology

It has good contact killing, stomach poisoning and fumigation effects, strong systemic absorption and high insecticidal activity. It can control a variety of pests on crops with one application. Compared with conventional organophosphorus pesticides, it has lower toxicity and is safe to use; it is safe for natural enemy populations. The impact is small, but due to years of use, many pests have developed resistance to it, resulting in a decline in the control effect
[0004] At present, the pesticide preparations with piflurid as the active ingredient are mainly 10% piflurid suspension concentrate, which is expensive to use in the actual use process, and there is a risk of resistance. Mixed use can not only achieve better control effect, have significant synergistic effect, but also reduce the cost of use, which is of positive significance for delaying the emergence of pest resistance, crop safety, and comprehensive management of pest resistance

Abstract

The invention discloses a disinfestation composition containing paichongding (IPP) and chlorpyrifos, of which the effective components comprise the paichongding and chlorpyrifos, and the weight ratio of the paichongding to the chlorpyrifos is 1:1-1:100. The composition can be prepared into the agriculturally allowable formulations such as wettable powder, suspending agents, suspension emulsion, missible oil or microemulsion; the invention has reasonable components, good disinfestation effect and low medication cost, and the activity and the disinfestation effect thereof are not the simple composition of activity of each component; compared with the existing signal formulation, the invention has obvious synergy effect besides the obvious disinfestation effect, slowers the generation of resistance, has small residual quantity of the formulation, no pollution to the crops and good safety, and accords with the safety requirement of the pesticide preparations; and the invention has excellent effect of preventing and controlling insects with sucking mouth parts on the plants such as rice, wheat, vegetables, fruit tree and the like.

Description

technical field [0001] The invention relates to an insecticidal composition containing pichamid, in particular to an insecticidal composition containing pichamid and chlorpyrifos, and belongs to the technical field of compound pesticides. Background technique [0002] The chemical name of piperidin is 1-((6-chloropyridin-3-yl)methyl)-5-propoxy-7-methyl-8-nitro-1,2,3,5,6,7 - Hexahydroimidazol[1,2-a]pyridine, the chemical formula is C 17 h 22 ClN 4 o 3 . Pichridam is a new type of high-efficiency, broad-spectrum, and low-toxic neonicotinoid insecticide. The mechanism of action is to act on the axonal receptors of insect nerves to block nerve conduction; Obvious antifeedant effect; acting on the stylet of piercing-sucking pests, making them unable to feed. Pichridam is mainly used to control Homoptera pests, and has a good control effect on rice planthoppers and other pests. Although pichridam has a new mechanism of action, because it is a new neonicotinoid insecticide, ...
