Abstract
The invention discloses a pesticide composition for agricultural pests and a pesticide thereof. The pesticide composition contains two active ingredients. The first active ingredient is emamectin benzoate, and the second active ingredient is 3-chloro-N1-(2-methyl-4-heptafluoroisopropyl-benzene)-N2-(1-methyl-cyano-ethyl) phthalic diamide. The weight ratio of the first active ingredient to the second active ingredient is 0.5-20:40-1. The pesticide composition is suitable for preventing and treating agricultural pests such as prodenia litura, asparagus caterpillars, plutella xylostella, striped rice borers, rice leaf folders and cotton bollworms and is better than a single pesticide on the aspects of fast-acting property and durable effect, the pesticide dosage and pesticide consumption cost are lowered, and environmental protection and comprehensive treatment of agricultural pests are facilitated.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of by emamectin-benzoate 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 is one of global Important Agricultural insect, serious harm agricultural production.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 of Lepidoptera class pest is relatively very fast, and resistance level is higher.Meanwhile, cause rampant again, the agricultural chemicals of insect residually to 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.
Emamectin-benzoate (hereinafter referred to as " emamectin benzoate ") is that efficient, wide spectrum, the longevity of residure are long, and be excellent insecticidal/acaricidal agent, its mechanism of action hinders pest movements nerve information transmission and makes health benumb death.The mode of action for main action of contace poison with stomach toxicity, to crop without interior absorption energy, but is effectively infiltrated and is used crop epidermal tissue, thus have the longer longevity of residure.To lepidoptera pests such as control cotton bolls, mite class, coleoptera and homoptera pest have high activity, and do not produce with other crops and intersect, soil and in easily to degrade noresidue, free from environmental pollution, to beneficial insect and natural enemy, people, animal safety in normal dosage ranges, can with most of combined use of pesticides.
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-first sulfonephthalein base-1,1-dimethyl ethane base-N-{4-" 1; 2; the fluoro-1-of 2,2-tetra-(trifluoromethyl) ethyl-o-tolyl } phthalamide, molecular formula is: C

4, belonging 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, is the compounds acting on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell few in number at present.There is wide spectrum preventive effect to lepidoptera pest, produce without cross resistance with existing insecticide, be suitable for very much the control that existing insecticide produces the insect of resistance.
When emamectin benzoate and ZJ4042 are used alone, drug cost is higher, limits it to a certain extent and applies, and is used alone for a long time and easily causes pest resistance degree constantly to increase.The mixture of different pesticide species is the common methods of preventing and treating agriculture resistant insect.Screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, 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 Lepidoptera class pest such as mixture control crops prodenia litura, beet armyworm, diamond-back moth, striped rice borer, rice leaf roller, cotton bollworm of emamectin benzoate and ZJ4042 there is no report and application at present.
Summary of the invention
The object of the present invention is to provide a kind of efficient, wide spectrum, low toxicity and the lasting period is long, agricultural pesticide composition and the insecticide thereof that effectively can prevent and treat crops Lepidoptera class pest.
For reaching goal of the invention the technical solution used in the present invention be:
For a Pesticidal combination for pest, containing two kinds of active components, the first active component is emamectin-benzoate active component is the chloro-N of 3-
1-(2-methyl-4-sevoflurane isopropyl base)-N
2-(1-methyl isophthalic acid-cyano ethyl) phthalic amide, the weight ratio that the first active component described and the second activity become is 0.5 ~ 20: 40 ~ 1.
The first active component above-mentioned and the weight ratio that becomes of the second activity are preferably 1 ~ 20: 30 ~ 1, and more preferably 1 ~ 10: 20 ~ 1, be particularly preferably 1 ~ 5: 10 ~ 1.
Present invention also offers a kind of insecticide for pest, by weight containing 5 ~ 90% above-mentioned Pesticidal combinations, all the other are agriculturally acceptable carrier and auxiliary agent.As preferred mode, containing 5 ~ 70% in described insecticide
Above-mentioned Pesticidal combination, is particularly preferably the Pesticidal combination containing 5 ~ 40% in insecticide.
Carrier of the present invention can be solid or liquid, and any carrier being generally used for preparing insecticides all can use.
