Abstract
The invention provides it is a kind of be not likely to produce the resistance to the action of a drug, can continuous and effective and have prevention effect higher insecticide, the active component of the insecticide is made up of pymetrozine and cartap, and the quality sum of pymetrozine and cartap accounts for the 30%~60% of insecticidal total quality.Insecticide of the present invention is by two kinds of controls of the ratio and content of active ingredient so that two kinds of active ingredients have obvious humidification, and its good disinsection effect, drug cost is low, achieve significant technique effect.
Description
Technical field
The invention belongs to agricultural technology field, it is related to a kind of insecticide, more particularly to it is a kind of containing pymetrozine and cartap
Insecticide.
Background technology
At present in the case where the exploitation of novel agrochemical compound is increasingly difficult to, pesticide combination technology is increasingly by producer
Pay attention to, become one of important channel of exploitation pesticide new product, but have one between each component in existing formulation of pesticide
Fixed resistance so that insecticidal effect reduction.One good mixed pesticide, can not only produce synergistic effect, and agricultural chemicals according to
Different proportion compounding use can increase inadaptability for insect, can delay drug-fast generation, the different mechanisms of action
Pesticide compositional can be complementary to one another, improve insecticidal effect, reduce Pesticide use amount, existing good economic and society imitates
Benefit, also mitigates the harm to environment.
The content of the invention
The technical problem to be solved in the present invention is directed to the deficiency of existing insecticide, there is provided one kind be not likely to produce the resistance to the action of a drug,
Being capable of continuous and effective and the insecticide with prevention effect higher.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme:
A kind of insecticide, the active component of the insecticide is made up of pymetrozine and cartap, the quality of pymetrozine and cartap
Sum accounts for the 30%~60% of insecticidal total quality.
The quality sum of pymetrozine and cartap accounts for the 40%~55% of insecticidal total quality
The insecticide is suspending agent, by the active component and dispersant, wetting agent, thickener, antifreezing agent and water by following
Mass percent is constituted:Pymetrozine 10%~45%, cartap 10%~30%, dispersant 1%~10%, emulsifying agent 2%~7%, wetting
Agent 2%~8%, thickener 0.1%~1%, antifreezing agent 0.1%~1% and excess water.
The dispersant is the one kind in alkylnaphthalene sulfonate, polycarboxylate, TERSPERSE 4894, lignosulfonates
Or its combination.
The emulsifying agent is agriculture breast 2201, sorbitan monostearate APEO, sorbitol anhydride monostearate
One kind or its combination in ester.
The thickener is one kind or its combination in polyvinyl alcohol, bentonite, xanthans.
The wetting agent be TERSPERSE 2500, naphthalene sulfonate, alkyl sulfate, alkylsulfonate in one kind or its
Combination.
Insecticide of the present invention is by two kinds of controls of the ratio and content of active ingredient so that two kinds of active ingredient tools
There is obvious humidification, its good disinsection effect, drug cost is low, the biocidal activity and insecticidal effect are not that each component is lived
The simple superposition of property, but have significant synergistic effect, its quick-acting is high, lasting effect is long, can slow down the generation of resistance, right
Crop safety is good, meets the security requirement of pesticidal preparations.
