Abstract
The invention discloses a kind of Pesticidal combination containing Tefluthrin, Pesticidal combination containing active components A Yu active component B, active components A is selected from Tefluthrin, active component B is selected from any one compound following: methoxyfenozide, spiral shell worm ethyl ester, metaflumizone, ring tebufenozide, and the weight ratio of active components A and active component B is 1 80 ~ 60 1.The present composition can prevent and treat various pests, and has obvious potentiation, expands insecticidal spectrum, and can reduce pesticide usage amount, reduces pesticide residual quantity on crop, alleviates environmental pollution.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination containing Tefluthrin answering on crop pest
With.
Technical background
Tefluthrin (Tefluthrin) chemical name: 2,3,5,6-tetra-fluoro-2-methyl base (suitable)-(1RS, RS)-3-(2-
Chloro-2,3,3-trifluoropropyl-1-thiazolinyls)-2,2-dimethyl cyclopropane carboxylic acid's ester, molecular formula: C17H14ClF7O2.Tefluthrin is to make
It is first pyrethroid that can be used as soil insecticide, efficient to coleoptera, Lepidoptera and dipteral insect, can be with granule
Agent, soil are sprayed or the mode of seed treatment is used.Its volatility is good, can the most fully divide a word with a hyphen at the end of a line to prevent and treat soil evil
Worm.It is about half-life one month big Tanaka, thus it can keep longer residual effect to insect, and be unlikely to cause in soil
Extended residual.
Methoxyfenozide (Methoxyfenozide) chemical name: the N-tert-butyl group-N'-(3-methyl-2-toluyl
Base)-3,5-dimethylbenzohydrazide, molecular formula: C22H28N2O3.The one of insect growth regulator, IGR.Ecdyson insecticides,
Suppression is ingested.Even if mainly the normal growth of interference insect is grown insect and is casted off a skin and dead.
Spiral shell worm ethyl ester (Spirotetramat) chemical name: 4-(ethoxy carbonyl epoxide)-8-methoxyl group-3-(2,5-bis-
Tolyl)-1-azaspiro [4,5]-decyl-3-alkene-2-ketone, molecular formula: C21H27NO5.Spiral shell worm ethyl ester has the function Characteristics of uniqueness,
Being the existing insecticide of the most rare two-way Uptake and translocation performance, insecticidal spectrum is wide, and the lasting period was long, it is possible to provide up to 8 weeks have
Effect preventing and treating.It is that the fatty biosynthesis by interference insect causes dead larvae, reduces the fertility of adult.Owing to it is only
Special mechanism of action, can prevent and treat the insect that existing insecticide produces resistance effectively, resists at the same time as nicotinic insecticide
Property management important kind.
Metaflumizone (Metaflumizone) chemical name: (E+Z)-[2-(4-cyano group benzene)-1-[3-(trifluoromethyl)
Benzene] ethylidene]-N-[4-(trifluoromethyl) benzene]-hydrazine carbonyl oxamides, molecular formula: C24H16 F6N4O2.Metaflumizone is a kind of
Urea insecticide, hot and cold storage is stable (54 DEG C).Mainly stomach poison function, band action of contace poison, hinders neural sodium path
Causing neural paralysis, preventing and treating lepidoptera and coleopteran pest, to mammal and non-target organism low-risk.
Ring tebufenozide (Chromafenozide) chemical name: 2,-the tert-butyl group-5-methyl-2,-(3,5-2 toluyl) color
Alkane-6-methylhydrazide, molecular formula: C24H30N2O3.Ring tebufenozide is bishydrazide insecticide, ring tebufenozide through insecticide absorb after
Suppressing insecticide feed to cause insecticide to cast off a skin in advance in several hours simultaneously and cause death, it is by regulation germling hormone and casts off a skin sharp
The molting process of element moving obstacle insecticide, causes the death of casting off a skin too early of insecticide.Because it can quickly suppress the feed of insecticide,
For the 1GR that other are conventional, the harm to crop can be reduced.
Summary of the invention

The embodiment of the present invention is the method using Toxicity Determination and field test to combine.First pass through indoor virulence to survey
Fixed, after clear and definite two kinds of medicaments are compounding by a certain percentage co-toxicity coefficient (CTC), CTC < 80 is antagonism, 80≤CTC≤120
For summation action, CTC > 120 is potentiation, on this basis, then carries out field test.
Test method: respectively the mother solution of each mixed agent is diluted to during test five series concentration, is respectively placed in beaker
Standby.Use the method that first leaching leaf is followed by worm, by the blade of the same size not in contact with any medicament in the medicinal liquid configured
Take out after soaking 5s, naturally dry, put in insect box, then connect for examination larva, raise under the conditions of 25 DEG C, often process 3
Secondary repetition, often repeating examination borer population used is 50, sets blank simultaneously, checks dead borer population in 72h, calculates mortality rate and correction
Mortality rate, tries to achieve virulence regression equation and calculates LC50Value.If comparison mortality rate is more than 10%, then it is considered as invalid test.Calculate public affairs
Formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) is converted into logarithm value (x), with minimum
Square law draws virulence regression equation, and thus calculates the value of every kind of medicament.Common poison system is calculated according to the abundant equation of Sun Yun
Number CTC.Computing formula is following (with Tefluthrin as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=Tefluthrin of MTefluthrinTI × the P of+active component BEffective active composition B
In formula: M is the mixture of different ratio
PEffective active composition BFor the ratio that effective active composition B is shared in the composition
PTefluthrinFor the ratio that Tefluthrin is shared in the composition

Cotton boll pests index is investigated before medicine, in insect pest early period of origination dispenser, 3 days, 7 days, investigation in 15 days after dispenser
Insect pest index also calculates preventive effect.Result of the test is as follows:
Table 22 Tefluthrin and active component B and the compounding preventing and treating cotton boll worm test of pesticide effectiveness thereof
As can be seen from Table 22, cotton boll worm, prevention effect can effectively be prevented and treated after Tefluthrin is compounding with active component B
It is superior to the preventive effect of single dose, and the preventive effect phase is long.In test scope of medication, target crop is had no adverse effects.
After draw through tests different local throughout the country, Tefluthrin and methoxyfenozide, spiral shell worm ethyl ester, cyanogen fluorine
To the beet armyworm on cereal crops, fruit tree, vegetable, flowers, fibre crops, legume crop, little after worm hydrazone, ring tebufenozide are compounding
Diamond-back moth, Prodenia litura, cabbage butterfly, flea beetle, Bemisia tabaci, olethreutid, small heart-eating peach worm, scale insect, red spider, planthopper, rice
The common worms such as leaf-roller, striped rice borer, bollworm, pink bollworm, bean-pod borer, aphid, tea lesser leafhopper, Pyrausta nubilalis (Hubern)., cutworm
The preventive effect of evil, all more than 95%, is better than single dose preventive effect, and potentiation is obvious.
