Abstract

The invention discloses an insecticidal composition containing effective components of HNPC-A8008, chemically named as (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl-4-trifluoromethyl sulfinyl pyrazol-3-nitrile, and metaflumizone. The weight ratio of the HNPC-A8008 to the metaflumizone is (1 to 100)-(100 to 1); the mass fraction percentage of the HNPC-A8008 and the metaflumizone is 10%-60% of the total mass of the insecticidal composition. Finished preparations of the insecticidal composition comprise missible oil or a microemulsion, a water emulsion, a suspending agent, wettable powder and a water dispersible granule. According to the insecticidal composition, the resistance risk of pests to medicaments is reduced; meanwhile, the limitations that a single component is relatively narrow in prevention and control spectrum and slowly acts or is short in lasting period are overcome, and the multiple kinds of pests can be simultaneously prevented and controlled by applying the insecticidal composition once; furthermore, the insecticidal composition maintains the advantage that the metaflumizone is long in lasting period, further has the advantage that the HNPC-A8008 is high in knockdown speed and is capable of preventing and controlling lepidoptera pests of crops such as vegetables, cotton, fruit trees and flowers; 1g-5g of the insecticidal composition is consumed in each mu (unit of area) of field; the insecticidal composition is an excellent substitute variety of high-toxicity pesticides.

Description

A kind of Pesticidal combination

Technical field

The present invention relates to a kind of Pesticidal combination; contained active ingredient is (E)-5-(3-chlorallyl) amino-1-(2; 6-dichlor-4-trifluoromethyl) phenyl-4-trifluoromethyl sulfinyl pyrazole-3-nitrile (test code number is HNPC-A8008) and metaflumizone, for preventing and treating paddy rice and vegetable-crop pest-insect.

Background technology

Chemical name is (E)-5-(3-chlorallyl) amino-1-(2; 6-dichlor-4-trifluoromethyl) compound (test code number is HNPC-A8008) of phenyl-4-trifluoromethyl sulfinyl pyrazole-3-nitrile is the pyrazoles noval chemical compound with insecticidal activity.The chemical structural formula of HNPC-A8008 is as shown in Equation 1:

HNPC-A8008 can be used for the control of the various crop such as paddy rice, vegetables insect, as beet armyworm, prodenia litura, striped rice borer, paddy stem borer, rice leaf roller, cabbage caterpillar etc., its mode of action is based on stomach toxicity, there is certain contact toxicity, systemic activity is more weak, quick-acting is good, and the lasting period is general.

Metaflumizone (metaflumizone), belongs to semicarbazone class, is a kind of insecticide of the brand-new mechanism of action, by being attached on the acceptor of sodium-ion channel, hinders sodium ion to pass through.The chemical structural formula of metaflumizone is as shown in Equation 2:

Metaflumizone is mainly entered by pests and in its body, stomach toxicity occurs and kill off the insect pests, and has action of contace poison, without systemic action simultaneously.This medicine is for the target pest in each length of time, larva has good control efficiency, after insect's food-taking, this medicine enters polypide, the sodium-ion channel on insect neuron axon film is blocked by the mechanism of action of uniqueness, make sodium ion not by axolemma, and then suppress nerve impulse to make excessive the loosening of polypide, paralysis, after several hours, namely insect stops taking food, dead in 1-3d, effectively can prevent and treat the larva of each Species of Lepidopterous Insect Pests and some coleoptera, adult, low to the acute toxicity of birds, to the low danger of honeybee, owing to can promptly be hydrolyzed and photodissociation in water, aquatile is endangered without reality.But metaflumizone due to insecticidal spectrum narrow, effect slowly, domestic production cost is high promote the use more difficult, therefore explore effective compound scheme for solving the drug effect of metaflumizone, Cost Problems has positive meaning.

Not yet there is the report of HNPC-A8008 and metaflumizone mixture application aspect at present.
