Description
Technical field the present invention relates to a kind of Recompounded pesticide, is the insecticides that active ingredient is mixed and forms with methoxyfenozide and capillary specifically, especially beet armyworm and diamond-back moth is had special efficacy.
Background technology is current, and the vegetables industry of China is just being showed a series of tendency.The science and technology-oriented consumer's diversified demand of growing vegetables trend environmental protection structure forms, and just directly guides the breed structure of vegetables industry to develop to nature, pollution-free green environment-friendly type direction.In planting process, use biopesticide or highly-effective low-residue chemical pesticide, ban use of highly toxic pesticide, Shaoshi chemical fertilizer as far as possible, many organic fertilizers material pollutes avoiding, reach the purpose that improves quality of vegetable, adapts to the domestic and international market demand, become the new trend that present vegetables produce.Beet armyworm is a kind of global insect.In recent years, break out in the many places of China and to cause disaster, harm spreads all over more than 20 province, city.Except that the harm brassicaceous vegetable, go back nearly hundred kinds of crops such as serious harm corn, peanut, soybean, cotton, tobacco, flowers, fruit tree.Along with the continuous enhancing of its resistance, the medicament of control beet armyworm is also more and more.Because the pesticide resistance of insect is more and more stronger, new drug newly developed also loses drug effect gradually after using several years, consider that drug-fast continuous increase constantly increases the using dosage of chemical agent, has increased cost and selling price, and contaminated environment.Show that through big quantity research and field trial the synergistic complex of agricultural chemicals is the effective ways that enlarge the pesticide control spectrum and improve drug effect.All crops in the harm scope almost all over the world of pest, evil mite.Along with the mankind to the attention of environmental protection and the enforcement of sustainable development; press for and develop more agricultural insecticidals efficiently, miticide; and when emphasizing high activity, high preventive effect, more should pay attention to safety, guarantee the safety of the mankind, environment and non-target organism.At present have the insecticide of good preventive effect to mainly contain to eliminate to beet armyworm, little noctuid etc., only a few medicaments such as fluorine bell urea, worm hydrazides, methoxyfenozide, and insect has all produced pesticide resistance to organic phosphor, pyrethrin pesticide, the preventive effect of many agricultural chemicals is very little, peasant household increases using dosage, not only increase expenses for prevention and control, also polluted environment greatly.
Methoxyfenozide (methoxyfenozide) belongs to the bishydrazide insecticide, moulting hormone for a kind of non-sterol type structure, simulate natural insect moulting hormones-20-HE, activate also and adhere to ecdysone receptor albumen, impel lepidopterous larvae before maturation, to enter the process of casting off a skin ahead of time and can not form healthy new epidermis.Thereby cause larva to stop to get food, final dead ahead of time.Different fully with other insecticide mechanisms of action that suppress the larva decortication, be applicable to the pest resistance comprehensive regulation.All effective to advanced age and low instar larvae, selectivity is strong, and the lasting period is longer, to crop safety, is difficult for producing poisoning, and antagonism insect beet armyworm etc. are effective.Its high efficiency, environment friendly are to meet people to the requirement of modern agricultural chemicals and development trend.But it is only effective to lepidopterous larvae, and quick-acting is poor.The thunder that Dow AgroSciences produces logical (24% methoxyfenozide suspending agent) is used in national large-scale popularization as the insecticide of control lepidoptera pest such as beet armyworm, prodenia litura etc., enjoy the peasant to welcome, yet in control of insect, along with the continuous lifting of pest resistance to insecticide, the control cost is more and more higher.Comparatively speaking, methoxyfenozide still has certain shortcoming on pest control.
Capillary (Chlorfenapyr) is the aryl pyrrolines insecticidal/acaricidal agent that American Cyanamid Company developed in the later stage eighties 20th century, and its chemical name is 4-bromo-2-(rubigan)-1-ethoxyl methyl-5-(trifluoromethyl) pyrroles-3-nitrile.Chinese common name chlorfenapyr.Capillary is the novel insecticidal/acaricidal agent of the class with its particular mechanism by the chemical constitution transformation of natural antibiotics is successfully developed, it is as a kind of precursor insecticide, in insect bodies, after sloughing the N-ethoxyethyl group, change into a kind of oxidative phosphorylation and separate even agent, because there is not target site in uncoupler itself, also just can not produce the target site resistance, thereby the control of many resistant insects had special efficacy, also therefore become worldwide in recent years new type disinsection miticide.Capillary is as the novel insecticidal/acaricidal agent of the class with its particular mechanism by the chemical constitution transformation of natural antibiotics is successfully developed, high-efficiency broad spectrum, all has excellent activity to chewing with sucking pest and evil mite, can be used for preventing and treating pest such as diamond-back moth, prodenia litura, cabbage caterpillar, vegetable aphid, especially carbamates, organic phosphates and pyrethroid pesticide have been produced the insect and the evil mite of resistance, special efficacy has been arranged as diamond-back moth, prodenia litura etc.But because the too high scope of application that has influenced it of its cost.The high consumption of capillary is higher to aquatic animal toxicity such as honeybee, fowl, bird and fishes in addition, has also limited its use relatively.
Present with the composite insecticide of capillary, domestic existing document and patent report.Relatedly in the Chinese patent CN 11698434A document carry out composite insecticide combination with capillary and biological species insecticide.Wherein, Avermectin develops immunity to drugs, and only continues to increase consumption, just can keep certain drug effect.In case and consumption strengthens, environment will be seriously damaged.On the contrary, methoxyfenozide and capillary carry out compositely not only can improving drug effect, reduce cost significantly, and two kinds of complementary drawbacks of composition have also increased insecticidal spectrum, have improved quick-acting greatly.
