Description

A kind of Efficient insecticidal composition
The application is divisional application, and original application is " a kind of high for the patent application of Shaanxi Welch Crop Protection Co., Ltd. Effect Pesticidal combination ", the application Wei ︰ 2012100617549 of original application, original application day is 2012.03.10.
Technical field
The invention belongs to technical field of pesticide, it is related to a kind of application of Efficient insecticidal composition on preventing and treating crop pest.
Background technology
Flufenzine (diflovidazin), molecular formula:C14H7CLF2N4, flufenzine contact goes out ovum and percutaneous activity, attracts mite Adult takes food, and also prevents and treats the acarid in pupa stage.The compound effects mechanism is unique, not only has excellent work to ovum and into mite Property, and female mite is produced unsound ovum, cause destroying the evidence for mite, to natural enemy and Environmental security.
Fenpyroximate (fenpyroximate), chemical name:(E) -4 [1,3- dimethyl-(5- phenoxy group -1H- pyrazolyls) Methene ammonia oxygen methyl] benzoic acid -1,1 dimethylethyl esters, molecular formula:C24H27N3O4, fenpyroximate is benzene oxygen pyrazoles acaricide.It is high Mite class can be directly killed during dosage, mite class decortication can be suppressed during low dosage or is laid eggs.With knocking down and suppressing decorticating, without in Suction is acted on.
Hexythiazox (hexythiazox), molecular formula:C17H21ClN2O2S, Hexythiazox is the new acaricide of thiazolidine ketone, There is preferable penetrability to plant epidermis layer, but without Uptake and translocation effect.There is strong ovicidal to various plants evil mite, kill The characteristic of children mite, to invalid into mite, but the ovum that female adult pest to touching liquid is produced has the effect for suppressing hatching.The medicine Belong to non-temperature sensitive type acaricide, the effect used in high temperature or low temperature is without significant difference, and the longevity of residure is long, be positively retained at 50 days left sides It is right.
Fenazaquin (fenazaquin), molecular formula:C20H22N2O, chemical formula:4- spy-butyl phenethyl quinazoline -4- bases Ether, the medicine is quinolines acaricide, by action of contace poison in the mitochondria and genome I of insect cell, occupies ubiquinone Abutment, to citrus trees, apple tree red spider has preferable prevention effect, and the lasting period is long, to natural enemies security.
However, in the real process of agricultural production, pest control is easiest to generate the problem that the product of pest resistance to insecticide It is raw.
Different cultivars composition is compounded, and is to prevent and treat the very common method of resistant insect.Heterogeneity is compounded, according to Practical application effect come judge certain compounding be synergy, plus and or antagonism.In most cases, the compounding of agricultural chemicals Effect is all additive effect, really have synergistic effect compounding seldom, especially synergistic effect clearly, co-toxicity coefficient it is very high Compounding just it is less.Studied by inventor, find to be produced after flufenzine and fenpyroximate, Hexythiazox, fenazaquin compounding Good synergistic effect, and not yet disclosed on the relevant report that flufenzine and fenpyroximate, Hexythiazox, fenazaquin are compounded.

The embodiment of the present invention is the method being combined using Toxicity Determination and field test.First pass through indoor virulence survey Calmly, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are compounded by a certain percentage, CTC < 80 are antagonism, 80≤CTC≤120 It is summation action, CTC > 120 are synergistic effect, on this basis, then carry out field test.
Test method:The mother liquor of each mixed agent is diluted to five series concentrations respectively during experiment, is respectively placed in beaker It is standby.Using the first leaching leaf method that is followed by worm, by not in contact with the blade of the same size of any medicament in the liquid for having configured Taken out after immersion 5s, dried naturally, be put into insect box, then connected for examination larva, raised under the conditions of 25 DEG C, often process 3 Secondary repetition, often repeats test worm number used for 50, while setting blank, dead borer population is checked in 72h, calculates the death rate and correction The death rate, tries to achieve virulence regression equation and calculates LC50Value.If the control death rate is more than 10%, it is considered as invalid experiment.Calculate public Formula is as follows:
Insect corrected mortality is converted into probit value (y), 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 equations of Sun Yun Number CTC.Computing formula is following, and (with flufenzine as standard agent, its toxicity index is for 100):
TI × the P of theoretical toxicity index (the TTI)=flufenzine of MFlufenzineTI × the P of+effective active composition BEffective active compositionB
In formula:M is the mixture of different ratio
PEffective active compositionB is effective active composition B ratios shared in the composition
PFlufenzineIt is flufenzine ratio shared in the composition
A is selected from flufenzine;
B is selected from following any one compound:One of fenpyroximate, Hexythiazox, fenazaquin are planted.
