Abstract

The invention discloses an agricultural insecticidal composition comprising thiamethoxam and ZJ4042, and an insecticide thereof. The composition comprises two active components. The first active component is thiamethoxam. The second active component is 3-chloro-N1-(2-methyl-4-heptafluoroisopropylphenyl)-N2-(1-methyl-1-cyanoethyl)polyphthalamide. The weight ratio of the first active component to the second active component is 1-50:30-1. The insecticidal composition provided by the invention is suitable to be used for controlling sucking mouthpart pests and lepidopteran pests, especially sucking mouthpart pests such as aphids, leafhoppers, planthoppers and whiteflies and lepidopteran pests such as prodenia litura, beet armyworms, diamondback moths, cotton bollworms, leaf rollers and rice stem borers. The insecticidal composition is better than single doses in the aspects of fast-acting property and persistence. With the insecticidal composition, pesticide dose and application cost are reduced. The insecticidal composition is beneficial for environment protection and agricultural pest comprehensive treatment.

Description

A kind of agricultural pesticide composition and insecticide thereof containing Diacloden and ZJ4042
Technical field
The invention belongs to pesticide field, be specifically related to a kind of by Diacloden and the chloro-N of 3- 1-(2-methyl-4-sevoflurane isopropyl base)-N 2the high-efficiency low-toxicity agricultural pesticide composition that-(1-methyl isophthalic acid-cyano ethyl) phthalic amide is composite and insecticide thereof.
Background technology
Lepidoptera class pest, sucking pest are one of global Important Agricultural insects, and 3R (resistance, then wildness, the residual) problem of chemistry of pesticide control is a global problem.Due to Long-Time Service single variety agricultural chemicals, the increase of Pesticide use amount and not scientifical use agricultural chemicals, the development of drug resistance speed goes of insect is fast, simultaneously, high dose uses organic phosphates, carbamates and the organochlorine insecticides agricultural chemicals high to mammalian toxicity, causes that residue of pesticide exceed standard, the series of problems such as environmental pollution and the increase of peasant's drug cost.Therefore, the pesticide of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.
Diacloden is a kind of anabasine insecticide of efficient, low toxicity, wide spectrum, its mechanism of action is Selective depression insect CNS nicotinic acetylcholine esterase acceptor mainly, and then block the normal conduction of insect CNS, cause insect to be poisoned to death.Diacloden not only have tag, stomach toxicity and systemic activity, and there is better safety, wider insecticidal spectrum and the feature such as speed of action is fast, the lasting period is long, be replace that those are high to mammalian toxicity, there have to be residual and the better kind of the organic phosphates of environmental problem, carbamates and organochlorine insecticides.To coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, effectively can prevent and treat the insect of the insects such as various aphid, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and knot polytype chemical pesticide generation resistance.
The chloro-N of 3- 1-(2-methyl-4-sevoflurane isopropyl base)-N 2-(1-methyl isophthalic acid-cyano ethyl) phthalic amide (hereinafter referred to as " ZJ4042 "), shown in structural formula following (I):
The insecticidal activity of this compound and the fipronil bisamide of recent development substantially suitable.Fipronil bisamide; English common name (flubendiamide) is researched and developed by Nihon Nihyaku Co., Ltd; chemical name is the iodo-N ' of 3--(2-mesyl-1; 1-dimethyl ethyl-N-{4-[1; 2; the fluoro-1-of 2,2-tetra-(trifluoromethyl) ethyl]-o-tolyl } phthalic amide, molecular formula is: C 23h 22f 7n 2o 4s, belong to Novel ortho benzenedicarboxamide insecticides, activate calcium release channel in blue Buddhist nun's alkali recipient cell, cause the runaway release of storing calcium ion, it is the compounds acting on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell few in number at present, produce without cross resistance with existing insecticide, be suitable for very much the control that existing insecticide produces the lepidoptera pest of resistance.
In agricultural production, lepidoptera pest and pierce-suck type often occur simultaneously, and when Diacloden and ZJ4042 are used alone, insecticidal spectrum is narrower.The pesticide species mixture of the Diacloden mechanism of action different from ZJ4042, not only effectively can expand insecticidal spectrum, and experiment shows synergistic effect in addition, can dosage be reduced, reduce costs, delay the generation of pest resistance to insecticide, extending the service life of medicament, is the important means of integrated pest management.
The mixture control sucking pest of Diacloden and ZJ4042 and Lepidoptera class pest there is no report and application at present.
