Abstract
The invention discloses a kind of nitrile of worm containing acetyl and the Pesticidal combination of sulfoxaflor, effective active composition is acetyl worm nitrile and sulfoxaflor, and the weight ratio of acetyl worm nitrile and sulfoxaflor 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 a kind of nitrile of worm containing acetyl and sulfoxaflor
Application of the Pesticidal combination 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.
Sulfoxaflor:The nervous system of insect is acted on, that is, is acted in choline receptor solely
Special binding site and play insecticidal function.Can be absorbed through leaf, stem, root and enter plant
It is interior.Sulfoxaflor is applied to prevents and treats cotton fleahopper, aphid, aleyrodid, plant hopper and coccid
Deng;Efficiently, the quick and longevity of residure is long, can effectively prevent and treat to nicotinoids, chrysanthemum esters, has
Phosphorus and carbamate chemicals for agriculture generation resistance the suction juice class pest of machine.To non-target segmental appendage
Animal toxicity is low, is integrated pest control preferred agents.
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
The relevant report of acyl worm nitrile and sulfoxaflor compounding is 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 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+Sulfoxaflor
TI × PSulfoxaflor
In formula:M is the mixture of different ratio
PSulfoxaflorIt is sulfoxaflor ratio shared in the composition
PAcetyl worm nitrileIt is acetyl worm nitrile ratio shared in the composition
Application Example two:
For examination insect:Cotton aphid
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
Experimental design:By pilot study determine acetyl worm nitrile and sulfoxaflor active compound and the two
Effective lethasl concentration scope of different ratio mixture.
Toxicity test result
The acetyl worm nitrile of table 9 compounds the toxicity test analysis of results table to cotton aphid with sulfoxaflor
As shown in Table 9, acetyl worm nitrile is matched in 1 ︰ 80~80 with sulfoxaflor to cotton aphid
During ︰ 1, co-toxicity coefficient is all higher than 120, illustrates both mixtures in the range of the ︰ 1 of 1 ︰ 80~80
Synergistic effect is shown, when the proportioning of acetyl worm nitrile and sulfoxaflor is 1:20~20:1
When, synergistic effect becomes apparent protruding, and co-toxicity coefficient is all higher than 230.Tested through applicant and sent out
Existing acetyl worm nitrile is 20 ︰ 1,19 ︰ 1,18 ︰ 1,17 ︰ with the optimum ratio of sulfoxaflor
1st, 16 ︰ 1,15 ︰ 1,14 ︰ 1,13 ︰ 1,12 ︰ 1,11 ︰ 1,10 ︰ 1,9 ︰ 1,8
︰ 1,7 ︰ 1,6 ︰ 1,5 ︰ 1,4 ︰ 1,3 ︰ 1,2 ︰ 1,1 ︰ 1,2:3rd, 1 ︰ 2,1
︰ 3,1 ︰ 4,1 ︰ 5,1 ︰ 6,1 ︰ 7,1 ︰ 8,1 ︰ 9,1 ︰ 10,1 ︰ 11,1 ︰ 12,
1 ︰ 13,1 ︰ 14,1 ︰ 15,1 ︰ 16,1 ︰ 17,1 ︰ 18,1 ︰ 19,1 ︰ 20, wherein
When acetyl worm nitrile and sulfoxaflor weight ratio are 2:Co-toxicity coefficient is maximum when 3, synergistic effect
The most substantially, to the beetle in various crop, leafhopper, aphid, aleyrodid, beet armyworm, small
The preventing and treating of diamond-back moth, rice leaf roller, striped rice borer, yellow rice borer, fleahopper, plant hopper or scale insect
There is obvious synergistic effect, co-toxicity coefficient is more than 120.
Effect experiment part:Test medicine is researched and developed by Shaanxi Welch Crop Protection Co., Ltd., carried
For acetyl worm nitrile suspending agent (autogamy) of comparison medicament 10%, 50% sulfoxaflor moisture dissipate
Granula (purchased in market).
