Abstract
The invention discloses an insecticidal composite containing sulfoxaflor and paichongding (ipp), wherein the weight ratio of the sulfoxaflor to the ipp is (1:8) to (8:1). The insecticidal composite can be prepared in the form of water dispersible granules, wettable powders, suspending agents, and diversifiable oil suspending agents. The insecticidal composite is reasonable in component, good in insecticidal effect, and low in application cost; the activity and insecticidal effect of the composite are not a simple sum of the activities and insecticidal effects of the components; compared with existing single preparations, besides having a significant insecticidal effect, the insecticidal composite also has an obvious synergistic effect, can slow down the production of resistance, has less preparation residual quantity, has no pollution to crops, is good in safety, and meets the safety requirement for pesticide preparations. The insecticidal composite has a good control effect on sucking pests on the crops such as rice, vegetables, cottons, fruit trees and the like.
Description
Technical field
The present invention relates to a kind of Pesticidal combination that contains fluorine pyridine worm amine nitrile and the pyridine of piperazine worm, belong to technical field of compounded pesticide.
Background technology
Fluorine pyridine worm amine nitrile english common name sulfoxaflor, chemical name are [1-[6-(trifluoromethyl) pyridin-3-yl] ethyl] methyl (oxygen)-λ 4-sulfydryl cyanamide, chemical molecular formula C

3OS.Fluorine pyridine worm amine nitrile is the sulfimide insecticides, and sulfimide acts on the nervous system of insect, promptly acts on binding site unique in the choline receptor and brings into play insecticidal function.Can be through leaf, stem, root absorption and enter in the plant corpus.Fluorine pyridine worm amine nitrile and other existing numerous insecticides do not have cross resistance, can prevent and treat most of homoptera pest, and especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect are applicable to vegetables, paddy rice, cotton, fruit tree and multiple field crop.But in actual application, use the agent of fluorine pyridine worm amine nitrile list to exist quick-acting relatively poor separately, insect easily produces the defective of resistance.
Piperazine worm pyridine chemical name is 1-((6-chloropyridine-3-yl) methyl)-5-propoxyl group-7-methyl-8-nitro-1,2,3,5,6,7-six hydrogen imidazoles [1,2-a] pyridine, and chemical molecular formula is C

3That the pyridine of piperazine worm belongs to is new and effective, the nicotinic insecticide of wide spectrum, low toxicity, and the mechanism of action is that the aixs cylinder that acts on the insect nerve is touched acceptor, the block nerves conduction; Act on gi system, insect has tangible food refusal effect after getting food; Act on the lancet of sucking pest, make it can't get food.The pyridine of piperazine worm is mainly used in the control homoptera pest, and insects such as rice fulgorid are had good control efficiency.Though the pyridine of piperazine worm has the new mechanism of action, because it belongs to new nicotinic insecticide, long-term single use still exists the risk that resistance produces.
At present, the pesticidal preparations that with fluorine pyridine worm amine nitrile is effective ingredient is based on 22% fluorine pyridine worm amine nitrile suspending agent, use cost is higher in actual use, and exist the risk that resistance produces, the piperazine worm pyridine that it is different with the mechanism of action is mixed to use and is expected to reach better prevention effect, the remarkable synergistic effect of tool, can reduce use cost again, to delaying the generation of pest resistance, to crop safety, the comprehensive regulation has positive meaning to pest resistance.
Summary of the invention
One of purpose of the present invention is to provide a kind of good disinsection effect, and drug cost is low, the Pesticidal combination that contains fluorine pyridine worm amine nitrile and the pyridine of piperazine worm that is difficult for developing immunity to drugs.
