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 Diacloden
Application of the 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.
Diacloden：The medicine is a kind of new High-efficiency low-toxicity broad spectrum.It is the new second generation
The first generation anabasine insecticides such as nicotinic insecticide, the mechanism of action and imidacloprid are similar,
But with activity higher.Have to insect stomach toxicity, tag, systemic action, speed of action
Hurry up, the features such as the lasting period is long.To sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc.
Preventive effect is preferable.
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 Thiamethoxam compound 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 good nitrile of worm containing acetyl and the Pesticidal combination of Diacloden.
The Pesticidal combination of the nitrile of worm containing acetyl proposed by the present invention and Diacloden, acetyl worm nitrile and thiophene
Worm piperazine weight ratio is the ︰ 1 of 1 ︰ 80~80, and acetyl worm nitrile and the preferred weight ratio of Diacloden are 1 ︰
40~40 ︰ 1；More preferably the weight ratio of acetyl worm nitrile and Diacloden is 20:1~1:20.

The embodiment 24 of table 8,25 each components and weight portion
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+Diacloden
TI×PDiacloden
In formula：M is the mixture of different ratio
PDiaclodenIt is Diacloden ratio shared in the composition
PAcetyl worm nitrileIt is acetyl worm nitrile ratio shared in the composition
Application Example two：
For examination insect：Orange caterpillar
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
Experimental design：Determine acetyl worm nitrile and Diacloden active compound by pilot study and the two is different
Match effective lethasl concentration scope of mixture.
