Dimethyl phenyl carbamate belongs to carbamate insecticide, for moderate toxicity, there is strong action of contace poison, the speed of knocking down is fast, the insects such as diptera, Lepidoptera and Homoptera are had to special efficacy, rice fulgorid, leafhopper are had to special efficacy, thrips, rice plant skipper, cotten aphid, cotton bollworm, anomis flava, bean aphid, soybean pod borer, soybean gelechiid, mythimna separata, Corn snout moth's larva, soil insect and cutworm, grub and tea tree, fruit tree pest insect are all had to good control efficiency.
For the disease control that easily produces resistance in agricultural, using the different pesticide species of the mechanism of action to carry out mixture is best selection, if reasonable mixture ratio can produce significant synergistic effect, makes field control effect obviously be better than the effect of each single dose at present.In agricultural disease control, usually there is certain defect in the bactericide that contains single-activity composition, continuous several times is used and not only makes pathogen easily develop immunity to drugs, usage amount is large, and easily cause the pollution to food and environment, can overcome above shortcoming by rational mixture between fungicidal activity composition.Reasonably the composite synergistic effect that active ingredient is produced, can improve preventive effect, reduces effective ingredient consumption, cost-saving, delays the drug-fast generation of pathogen, and then can alleviate and even avoid the pollution of agricultural chemicals to food and environment.
Have no at present the relevant report of the Pesticidal combination that contains Tolfenpyrad and Rynaxypyr, dimethyl phenyl carbamate.
Summary of the invention
The object of the invention is in order to overcome the consumption that above-mentioned single insecticide exists large, the shortcomings such as environmental pollution is serious and the problem that contains each single dose composition existence, and a kind of Pesticidal combination containing Tolfenpyrad is provided, under optimal proportion, there is formula synergistic effect, not only expand the range of application of each single dose, simultaneously in the usage amount that ensures to reduce under optimum preventive effect medicament, reduce mu usage amount, thereby reduce costs and reduce environmental hazard, can delay the generation of pest resistance.
Technical scheme of the present invention:

Experiment embodiment 1:
For examination insect: maize borer, for subsequent use after 2 ages of artificial feeding.
Reagent agent: provided by Guangxi Tianyuan Biochemical Co., Ltd..
Experimental design: effective lethal concentration scope of determining Tolfenpyrad, the former medicine of Rynaxypyr and the two different proportioning mixture through preliminary experiment, each medicament designs respectively five gradient concentration processing by active constituent content, contrasts with the space management that does not contain former medicine.
Test method: respectively the mother liquor dilution of Tolfenpyrad, Rynaxypyr and each mixed agent is become to following 5 series concentration when test, be placed in respectively beaker for subsequent use.Adopt and first soak the method that connects worm after corncob bar, the fresh corn male flower fringe bar of the same size that does not contact any medicament is soaked and within 5 seconds, takes out afterwards, naturally dries in the mother liquor configuring, put into insect box, then connect for examination maize borer, under 25 DEG C of constant temperatures, raise, every processing repeats for 3 times, every to repeat examination worm used be 30, establishes blank, within 48 hours after medicine, checks dead borer population, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50value.If contrast lethality is greater than 10%, be considered as invalid test.Computing formula is as follows:
Maize borer corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) is converted to logarithm value (x), draws virulence regression equation with method of least squares, and calculates thus the value of every kind of medicament.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (taking Rynaxypyr as standard medicament, its toxicity index is 100):
