Description
Technical field
The present invention relates to a kind of Pesticidal combination, particularly a kind of the first active component is methoxyfenozide, the second active component is selected from the Pesticidal combination of ether chrysanthemum ester, Biphenthrin or gamma cyhalothrin pyrethroid insecticides, belongs to technical field of compounded pesticide.
Background technology
Methoxyfenozide, english common name: methoxyfenozide, other English names: Intrepid, Runner, chemical name: the N-tert-butyl group-N '-(3-methyl-2-toluyl groups)-3,5-dimethyl benzene formylhydrazine.Methoxyfenozide belongs to the bishydrazide insecticide, it is a kind of insect growth regulator, IGR, moulting hormone for a kind of non-sterol type structure, simulation natural insects moulting hormone---20-HE, activation is also adhered to ecdysone receptor albumen, impel lepidopterous larvae before maturation, to enter ahead of time the process of casting off a skin and can not form healthy new epidermis, thus cause larva stop ahead of time taking food, final dead.The reaction that lepidopterous larvae is ingested behind the methoxyfenozide is fast.Larva namely stops to take food after generally ingesting 4～16 hours, poisoning symptom occurs.The methoxyfenozide of selling in the market is the suspending agent of 240 grams per liters, as a kind of bionical steroids insecticide, it has low dose, holding effect is long, stable, efficient, the characteristics such as environment friendly, to meet people to the requirement of modern and development trend, but methoxyfenozide in use exists the use cost height, the defective of the risk that resistance increases.
Ether chrysanthemum ester (english common name etofenprox, chemical molecular formula C

3Gamma cyhalothrin is a kind of pyrethroid insecticides, have and tag, stomach poison function, without interior suction, fumigation action, insecticidal spectrum is wide, effect rapidly, the mechanism of action is for suppressing the conduction at insect neural axon position, insect had walk quickly and keep away, the effect of knocking down and killing, the effect characteristics are that insecticidal spectrum is wide, activity is higher, and drug effect is rapid, resistance of rainwater washing against after spraying, but long-term the use easily produces resistance to it, insect and evil mite to sucking mouth parts have certain preventive effect, but the using dosage of mite is increased 1-2 doubly than conventional amount used, are applicable to peanut, soybean, cotton, fruit tree, the insect of vegetables.Prevent object: be used for the control Fructus Hordei Germinatus such as wheat, corn, fruit tree, cotton, brassicaceous vegetable, midge worm, mythimna separata, corn borer, beet armyworm, heart-eating worm, leaf roller, dive noctuid, swallowtail butterfly, fruit piercing moth, cotton bollworm, red instar, cabbage caterpillar etc., be used for grassland, meadow, dry crop control beet webworm etc.
At present, the pesticidal preparations take methoxyfenozide as effective ingredient is take 240 grams per liter methoxyfenozide suspending agents as main, and in actual use, lasting effect is long, but quick-acting is general, and use cost is high; Ether chrysanthemum ester, Biphenthrin, gamma cyhalothrin are as pyrethroid insecticides, sell in the market and mostly be greatly single dose, good disinsection effect, quick-acting is fast, but exists use cost to raise, easily it is produced resistance, the defective that lasting period is general, the inventor is unexpected to find that the use that is mixed of methoxyfenozide and pyrethroid insecticides is had significant synergistic effect, can reduce use cost, slow down the effect of the generation of pest resistance.
