Abstract
The invention discloses an insecticidal composition containing tefluthrin, which is an insecticidal composition containing active component A and active component B; the tefluthrin is chosen as the active component A; any one of the following compounds is chosen as the active component B: pymetrozine, dicyclanil, ethiprole, pyriproxyfen and chlorfenapyr; and the weight ratio of the active component A to the active component B is 1:80 to 60:1. The insecticidal composition has a synergic effect on a variety of pests jeopardizing agricultural production, the dosage of the insecticide is reduced, the amount of the residual insecticide on crops is reduced, environment pollution is reduced, the insecticidal composition is safe for the human being and livestock, and is highly compatible with the environment, and pests cannot easily generate insecticide resistance.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pests that contains tefluthrin.
Background technology
Tefluthrin (Tefluthrin) chemical name: 2,3,5,6-tetrafluoro-methyl-benzyl (suitable)-(1RS, RS)-3-(2-chloro-2,3,3-trifluoropropyl-1-thiazolinyl)-2,2-dimethyl cyclopropane carboxylic acid ester, molecular formula: C
17H
14ClF
7O
2Tefluthrin is the pyrethroid that can be used as soil insecticide as first, and is efficient to coleoptera, Lepidoptera and dipteral insect, can granule, soil sprays or the mode of seed treatment is used.Its volatility is good, can in gas phase, fully divide a word with a hyphen at the end of a line with the control soil pests.Half life period be about one month big Tanaka, thereby it can keep longer residual effect to insect, and be unlikely in soil, to cause extended residual.
Pyrrole aphid ketone (pymetrozine) chemical name: 4,5-dihydro-6-methyl-4-(the 3-pyridine methylene is amino)-1,2,4-3 (2H)-ketone, molecular formula: C
10H
11N
5O.These article can be used for preventing and treating most of homoptera pest, and especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect insect are applicable to vegetables, paddy rice, cotton, fruit tree and multiple field crop.
CGA 183893 (dicyclanil) chemical name: 4,6-diaminourea-2-cyclopropyl aminopyrimidine-5-nitrile, molecular formula: C
8H
10N
6The decortication of CGA 183893 interference insect after the absorption of insect genital system, stops larvae pupation or becomes worm.
Inferior sulphur (sulphur) acyl group of second worm nitrile (ethiprole) chemical name: 5-amino-1-(2,6-two chloro-p-trifluoromethyl phenyls)-4-ethyl pyrazoles-3-itrile group, molecular formula: C
13H
9C
L2F
3N
4OS.Second worm nitrile is the novel pyrazole insecticides, and insecticidal spectrum is wide, disturbs chloride channel through GABA (GABA), thereby destroy central nervous system (CNS) normal activity insect is caused death.This medicine is tightr to the constraint comparison vertebrate of insect GABA chloride channel, thereby very high selection toxicity is provided.Its mechanism of action is different from main insecticide families such as pyrethroid, organic phosphor, carbamate, does not almost produce the chance of interactivity with the existing insecticide of majority.Therefore, it is the desirable reserve kind of resistance management, can be with the mixed pesticide of other chemical family, be used alternatingly.
Pyrrole propyl ether (pyriproxyfen) chemical name: 4-Phenoxyphenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether, molecular formula: C
