Description
Technical field
The present invention relates to a kind of Pesticidal combination, relate in particular to a kind of Pesticidal combination that comprises the first active substance Tolfenpyrad and the second active substance cycloxaprid.
Background technology
At present for the control of insect that easily produces resistance in agricultural, what main way was exploitation and existing kind without between the new composition of cross resistance or existing pesticide species is composite, the former is because required development cost is high, the cycle is long, and the speed that development rate produces less than pest resistance to insecticide far away at present.Therefore, for the different existing pesticide species of the mechanism of action, carry out the selection that mixture is a kind of the best.If reasonable mixture ratio, can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.On agricultural insect pests control, usually there is certain defect in the insecticide that contains single-activity composition, continuous several times is used and is not only made insect easily develop immunity to drugs, and easily cause the pollution to food and environment, by rational mixture between pesticide active ingredient, can overcome above shortcoming.The reasonably composite synergistic effect that active ingredient is produced simultaneously, can improve preventive effect, reduce effective ingredient consumption, cost-saving, delay the drug-fast generation of insect, closely can alleviate and even avoid the pollution of agricultural chemicals to food and environment, and the efficient novel pesticide of the low toxicity that the present invention researchs and develops, not only target drug effect is significantly strengthened, and very low on the impact of people, crop, non-target and environment.
Tolfenpyrad (Tolfenpyrad), chemical name is: the chloro-3-ethyl-1-of 4-methyl-N-{[4-(4-methylphenoxy) phenyl]-methyl }-1H pyrazoles-5-carboxylic acid amides, its structural formula is:
The novel pyrazole heterocyclic insecticidal/acaricidal agent of Tolfenpyrad Shi Yuan Mitsubishi chemical company (its agricultural chemicals part now belong to Japanese agricultural chemicals company) exploitation, its mechanism of action is that the electronics hindering in mitochondrial metabolic system is passed on system complex I, thereby electronics is passed on to be hindered, insect can not be provided and storing energy, be called as mitochondria electronics and pass on complex Inhibitors (METI).Insecticidal spectrum is wide, demonstrates for example, broad-spectrum insecticidal activity for various pests (Semiptera (Hemiptera), coleoptera (Coleoptera), diptera (Diptera), Lepidoptera (Lepidoptera), thrips (Thysanoptera) and mite class).Tolfenpyrad mainly provides the prevention and control activity of ovum, larva, pupa and adult to object insect.Its structural formula is as follows:
Cycloxaprid (Cycloxaprid) is a kind of novel anabasine insecticide, its chemical name is: 9-(6-chloropyridine-3-yl) methyl)-4-nitro-8-oxa--10,11-glyoxalidine also (2,3-a) dicyclo (3,2,1) pungent-3-alkene, molecular structural formula is:
Cycloxaprid is the antagonist of first nAChR in the world, very likely becomes the new class insecticide in the world with material impact power, and its activity is significantly better than Imidacloprid.Insect is had to interior suction, stomach toxicity and action of contace poison, can be used for preventing and treating Homoptera, coleopteran pest on crops, without cross resistance, also effective to lepidoptera pest with Imidacloprid, Acetamiprid, Diacloden etc.This product using dosage is low, environmentally safe, to beneficial organism without harm or endanger minimum.Aphid to crops such as wheat, cotton, paddy rice, fruit tree, vegetables, plant hopper, aleyrodid, flea beetle, cotton bollworm, diamond-back moth, prodenia litura, armyworm etc. have higher insecticidal activity.In addition, its honeybee toxicity also significantly reduces, 48 hours acute absorption LC of cycloxaprid
50for 19.18mg/L, and Imidacloprid is 4.94mg/L, and toxicity is starkly lower than Imidacloprid, and environmental safety is got a promotion.In addition, the tapeworm to sheep, rabbit and coccidia demonstrate excellent activity.As the novel anabasine insecticide of one, it is high that cycloxaprid exists use cost after listing, the risk that resistance risk increases gradually, and it is efficient to homoptera pest, but poor to lepidoptera pest drug effect.
Often there is defect in various degree in the insecticide variety that contains single-activity component: after using continuously, insect easily develops immunity to drugs on agricultural insect pests control, the many pollutions that will increase the weight of environment of access times.And that different component carries out is composite, can effectively overcome above shortcoming.Meanwhile, the synergistic effect that utilizes two kinds of active component mixtures to produce, can improve preventive effect, reduces the consumption of active ingredient, saves drug cost, delays insect, the drug-fast generation of evil mite, reduces environmental pollution, is the important means of integrated control insect.At present, Tolfenpyrad and cycloxaprid composite and application there is no people and reported.
