Abstract
The invention discloses a kind of nitrile of worm containing acetyl and the Pesticidal combination of AVM, effective active composition is acetyl worm nitrile and AVM, and the weight ratio of acetyl worm nitrile and AVM is the ︰ 1 of 1 ︰ 80~80.The present composition has synergistic effect to the various pests for endangering agricultural production, reduces pesticide usage amount, reduces residual quantity of the agricultural chemicals on crop, alleviates environmental pollution, and to person poultry safety, Environmental compatibility is good, and insect is not likely to produce the resistance to the action of a drug.
Description
Technical field
The invention belongs to technical field of pesticide, it is related to killing for a kind of nitrile of worm containing acetyl and AVM
Application of the worm composition on crop pests.
Background technology
Acetyl worm nitrile：Molecular formula：C13H10Cl2F3N3O2S, acetyl worm nitrile is a wide spectrum
Insecticide, its insecticidal mechanism is the chlorine for hindering insect GABA (GABA) control
Compound is metabolized.
AVM：A kind of f macrolide disaccharide compound.It is from edaphon
The natural products of separation, has to insect and mite class and tags and stomach poison function and have faint smoked
Steaming is acted on, without systemic action.But it has very strong osmosis to blade, epidermis can be killed
Under insect, and the longevity of residure is long.Its not ovicidal.Its mechanism of action is different from general insecticide
Be that it disturbs nervous physiology activity, stimulate release r- aminobutyric acids, and r- aminobutyric acids
Have inhibitory action to the nerve conduction of arthropod, mite class into, deutonymph and insect and larva with
There is paralysis symptom after medicament contact, inertia does not take food, it is dead after 2 to 4 days.Cause
Insect rapid dehydration is not caused, so its lethal effect is slower.But to predatism and parasitism
Though property natural enemy has direct killing effect, because plant surface residual is few, therefore to the damage of beneficial insect
Wound is small.
But in the real process of agricultural production, pest control is easiest to generate the problem that
The generation of pest resistance to insecticide.Different cultivars composition is compounded, and is that preventing and treating resistant insect is very normal
The method seen.Heterogeneity is compounded, and judges that certain is answered according to practical application effect
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 very
Substantially, co-toxicity coefficient compounding very high is just less.Studied by inventor, found second
Acyl worm nitrile and abamectin compounded relevant report are not yet disclosed.
The content of the invention
Have that synergistic function, use cost be low, preventive effect the purpose of the present invention is to propose to one kind
The good nitrile of worm containing acetyl and the Pesticidal combination of AVM.

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+AVM
TI×PAVM
In formula：M is the mixture of different ratio
PAVMIt is AVM 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：By pilot study determine acetyl worm nitrile and the former medicine of AVM and the two not
With effective lethasl concentration scope of proportioning mixture.
