Description
Technical Field
The invention belongs to the field of pesticides, and particularly relates to an insecticidal composition taking pyridalyl and chlorfenapyr as main active ingredients and application thereof.
Background
Pyridalyl (Pyridalyl), chemical name: 2- {3- [ 2.3-dichloro-4- (3, 3-dichloro-2-propenyloxy) phenoxy ] propoxy } -5- (trifluoromethyl) pyrimidine, structure formula.
The pyridalyl is also called pyridalyl, is a novel pyrimidine high-efficiency and low-toxicity insecticide developed and developed by Sumitomo chemical company in Japan, has excellent control effect on lepidoptera pests, and has no cross resistance with the existing lepidoptera insecticide. It has excellent contact poisoning and stomach poisoning preventing effect.
The existing data are queried for pyridalyl and many other pesticides such as: the pesticide formulations such as missible oil and the like prepared from destruxins of Metarrhizium anisopliae, monosultap, dimehypo and the like have good synergistic effect on killing lepidoptera pests.
Chlorfenapyr (Chlorfenapyr), chemical name: 4-bromo-2- (4-chlorophenyl) -1- (ethoxymethyl) -5- (trifluoromethyl) pyrrole-3-carbonitrile. The structural formula is shown as follows.
Chlorfenapyr, also called chlorfenapyr, is an insecticide precursor, and has no toxic effect on insects. After feeding or contacting with chlorfenapyr in the insect body, the chlorfenapyr is converted into a specific insecticidal active compound under the action of a multifunctional oxidase, and the target of the compound is mitochondria in the cells of the insect body. The cell synthesis stops the life function due to the lack of energy, and the pests become weak in activity, appear speckles, change in color, stop in activity, coma, paralysis and softness after insecticide injection, and finally die. Can effectively prevent and control various pests on crops such as grains, cotton, fruits, vegetables and the like.
The chlorfenapyr has excellent control effect on boring, sucking and chewing pests and mites, is more effective than cypermethrin and cyfluthrin, and has stronger acaricidal activity than dicofol and cyhexatin. The medicament has the following characteristics: broad-spectrum insecticidal and acaricidal agents; has stomach toxicity and contact poisoning effects; no cross resistance with other insecticides; moderate residual activity on crops; absorbing the active ingredients in nutrient solution through root system; the oral toxicity to mammals is moderate, and the transdermal toxicity is low; the effective application amount is low.
The chlorfenapyr has a wide insecticidal spectrum, and field experiments and practical applications show that the chlorfenapyr has an excellent control effect on more than 70 pests in Lepidoptera, Homoptera, Coleoptera and the like, and particularly has special effects on diamond back moths, beet armyworms, prodenia litura, liriomyza sativae, stigmatis suppressalis, thrips, red spiders and the like in vegetable resistant pests. The chlorfenapyr belongs to a bionic pesticide, has low toxicity and high insecticidal speed, can kill pests after being applied for 1 hour, and has the control effect of more than 85 percent on the same day. The resistance is broken, the action mechanism is unique, the resistance is different from that of other insecticides, the cross resistance is avoided, and the resistance is high-efficiency to pests with serious drug resistance. Especially has good effect on pests and mites which have resistance to organophosphorus, carbamate, pyrethrin and chitin synthesis inhibitor insecticides. The effective period is especially long, the effective period can be controlled for 15-20 days on the prevention and control of resistant pests, and the residual effective period for preventing and controlling red spiders is as long as 35 days. The chlorfenapyr is a naturally screened pyrrole substance and is very safe to human bodies and livestock. Is particularly suitable for being used in export products and high-quality products.
Currently, chemical control exists in which repeated single use of a certain pesticide or composition results in resistance to the pest, and there is a need to provide pesticidal compositions that overcome the resistance. Chemical control requires a composition that can reduce the rate of use, reduce the environmental impact, and provide effective control while achieving quick and long lasting effects on pests. Accordingly, the present invention aims to provide an insecticidal composition which solves at least one of the above problems: such as delaying resistance, improving activity, reducing usage rate, etc.
