Description
Technical field
The invention belongs to technical field of pesticide, it is related to the Pesticidal combination of a kind of nitrile of worm containing acetyl and multiple killing teichomycin in farming
Application on thing insect.
Background technology
Acetyl worm nitrile：Molecular formula：C13H10Cl2F3N3O2S, acetyl worm nitrile is a broad spectrum pesticide, and its insecticidal mechanism is
Hinder the chloride metabolism of insect GABA (GABA) control.
Multiple killing teichomycin：Have to insect and quickly tag and stomach poison function, there is stronger osmosis to blade, can kill
Subepidermal insect, the longevity of residure is more long, has certain ovicidal action to some insects, without systemic action.
But 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 reality
Application effect come judge certain compounding be synergy, plus and or antagonism.In most cases, the compounding effect of agricultural chemicals
All it is additive effect, really has the compounding of synergistic effect seldom, especially synergistic effect is clearly, co-toxicity coefficient is very high answers

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, and common poison system is calculated according to the abundant equations of Sun Yun
Number CTC.Computing formula is following, and (with acetyl worm nitrile as standard agent, its toxicity index is for 100)：
TI × the P of the theoretical toxicity index (TTI) of M=acetyl worm nitrileAcetyl worm nitrile+TI × the P of multiple killing teichomycinMultiple killing teichomycin
In formula：M is the mixture of different ratio
PMultiple killing teichomycinIt is multiple killing teichomycin ratio shared in the composition
PAcetyl worm nitrileIt is acetyl worm nitrile ratio shared in the composition
Application Example two：
For examination insect：Brassicaceous vegetable diamondback moth
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
Experimental design：Determine having for acetyl worm nitrile and multiple killing teichomycin active compound and the two different ratio mixture by pilot study
Effect lethasl concentration scope.
