Description
Technical field
The invention belongs to technical field of pesticide, it is related to the desinsection of a kind of nitrile of worm containing acetyl and pymetrozine
Application of the composition on crop pests.
Background technology
Acetyl worm nitrile (methoxyfenozide) molecular formula：C13H10Cl2F3N3O2S, acetyl
Worm nitrile is a broad spectrum pesticide, and its insecticidal mechanism is to hinder insect GABA
(GABA) the chloride metabolism of control.
Pymetrozine (pymetrozine) molecular formula：C10H11N5O, this product can be used to prevent and treat big
Part homoptera pest, especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect insect,
Suitable for vegetables, paddy rice, cotton, fruit tree and various field crops.
However, in the real process of agricultural production, pest control is easiest to the problem for producing
It is the generation of pest resistance to insecticide.Different cultivars composition is compounded, and is to prevent and treat resistant insect very
Common method.Heterogeneity is compounded, and certain is judged according to practical application effect
Compounding is synergy, adds and or antagonism.In most cases, the compounding effect of agricultural chemicals
Fruit is all additive effect, really has the compounding of synergistic effect seldom, and especially synergistic effect is non-
Chang Mingxian, co-toxicity coefficient compounding very high are just less.Studied by inventor, finding will
Good synergistic effect can be produced after acetyl worm nitrile and Pyraphione compound, and on acetyl worm nitrile
Relevant report with Pyraphione compound is not yet disclosed.

The embodiment of the present invention is the method being combined using Toxicity Determination and field test.First
By Toxicity Determination, clear and definite two kinds of medicaments compound by a certain percentage after co-toxicity coefficient
(CTC), CTC ＜ 80 are antagonism, and 80≤CTC≤120 are summation action, CTC ＞
120 is synergistic effect, on this basis, then carries out field test.
Test method：The mother liquor of each mixed agent is diluted to five series concentrations respectively during experiment,
It is respectively placed in standby in beaker.Using the method that first leaching leaf is followed by worm, will be not in contact with any medicament
Blade of the same size 5s is soaked in the liquid for having configured after take out, dry naturally, put
Enter in insect box, then connect for examination larva, raised under the conditions of 25 DEG C, often process 3 times
Repeat, often repeat test worm number used for 50, while setting blank, check dead in 72h
Borer population, calculates the death rate and corrected mortality, tries to achieve virulence regression equation and calculates LC50Value.
If the control death rate is more than 10%, it is considered as invalid experiment.Computing 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), virulence regression equation is drawn with least square method, and thus calculates every kind of medicine
The value of agent.Co-toxicity coefficient CTC is calculated according to the abundant equations of Sun Yun.Computing formula it is following (with
Acetyl worm nitrile is standard agent, and its toxicity index is for 100)：
TI × the P of the theoretical toxicity index (TTI) of M=acetyl worm nitrileAcetyl worm nitrile+ pymetrozine
TI×PPymetrozine
In formula：M is the mixture of different ratio
PAcetyl worm nitrileIt is acetyl worm nitrile ratio shared in the composition
PPymetrozineIt is pymetrozine ratio shared in the composition
Application Example two
For examination insect：Brassicaceous vegetable aphid
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
Experimental design：Determine acetyl worm nitrile and pymetrozine active compound by pilot study and the two is different
Match effective lethasl concentration scope of mixture.
