The insecticidal composition consists of the active ingredients of clothianidin and ethiprole, wherein the mass ratio of the clothianidin to ethiprole is (1:15)-(15:1); and the sum of the mass of the clothianidin and ethiprole accounts for 1-80 percent of total mass of the insecticidal composition. The mixed preparation is reasonable in component, good in insecticidal effect and low in administration cost, and the activity and the insecticidal effect are not simply superposed by activities of various components; and moreover, the insecticidal composition has the obvious synergistic effect, high in fast-acting property, high in persistence and high in crop safety, the resistance can be relieved, and the safety requirements on the pesticide preparations are met.
Description
Technical field
The invention belongs to agricultural technology field ， Shibuya and a kind of Pesticidal combination, relate in particular to a kind of Pesticidal combination that contains clothianidin and second worm nitrile.
Background technology
Clothianidin is a kind of insecticide in anabasine, its English common name: clothianidin, molecular formula: C
6H
8ClN
5O
2S, molecular weight: 249.7, chemical name: (E)-1-(2-chloro-1,3-thiazoles-5-ylmethyl)-3-methyl-2-2-nitroguanidine, former medicine outward appearance is the crystalline solid powder, and is odorless, 176.8 ℃ of fusing points.
Clothianidin is the novel pesticide of a class highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Be mainly used on paddy rice, vegetables, fruit tree and other crops anti-ly eliminating aphis, the insecticide of Semiptera, coleoptera, diptera and some Lepidoptera class pest such as leafhopper, thrips, plant hopper, have efficient, wide spectrum, consumption is few, toxicity is low, the drug effect lasting period long, to crop without poisoning, use safety, with conventional pesticide without advantages such as cross resistances, remarkable interior suction and osmosis are arranged, and are the another kinds that substitutes high malicious organophosphorous pesticide.
The synthetic method of report mainly contains four kinds both at home and abroad at present: (1) uses CCT and N-methyl-N/-nitro-S-methyl isothiourea reaction; (2) use 2-chloro-5-chloromethyl-l, 3-thiazole and N-methyl-N, the reaction of-nitrourea; (3) use CCT and N-nitro-S-methyl isothiourea reaction, obtain 1-(2-chloro-thiazole methyl)-N-nitro-S-methyl isothiourea, then methylamine obtains product; (4) by decomposing 1-(2-diuril azoles-5-methyl)-2-nitro-imine base-3,5-dimethyl-six hydrogen-1,3,5-triazines prepares product.
Second worm nitrile (Ethiprole) is the novel pyrazole insecticides, and molecular formula is C13H9Cl2F3N4OS, chemical name: 1-(2,6-dichlor-4-trifluoromethyl phenyl)-3-cyano group-4-ethyl sulfinyl-5-amino-pyrazol.The ethiprole insecticidal spectrum is wide; disturb chloride channel by r-aminobutyric acid (GABA); thereby it is lethal with insect to destroy central nervous system (CNS) normal activity; it belongs to the insecticide that the second generation acts on GABA; effective to multiple chewing type and sucking pest under low consumption; can be used for seed treatment and foliar spray, the lasting period reaches 21-28 days.Be mainly used in preventing and treating thrips, stinkbug, curculionid, beet gelechiid, aphid, plant hopper and locust etc.
In the middle of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Most important insect such as Homoptera and Lepidoptera class on agricultural, because its breeding cycle is short, breeding amount is large, and harm is heavy, and a kind of single dose control of long-term single use is easily developed immunity to drugs.The medicine of the sucking pests such as the aphid of common single control paddy rice aleyrodid, leafhopper and fruits and vegetables class, thrips, aleyrodid such as Imidacloprid, Nitenpyram, pyridine worm narrow etc. and to be difficult to obtain control efficiency preferably, have produced serious resistance and be mainly used in preventing and treating the dive conventional control pesticide avermectin, organic phosphates etc. of fly of rice grub rice leaf roller, fruits and vegetables class pest striped flea-beetle, tangerine lyonetid, beans.
