The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Earlier by Toxicity Determination, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker standby respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then for the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times, every to repeat used examination borer population be 50, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is considered as invalid test greater than 10%.Computing formula is as follows:
The insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (be standard medicament with the Tolfenpyrad, its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=Tolfenpyrad of M
TolfenpyradTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P

A is selected from Tolfenpyrad;
B is selected from a kind of in alkynes mite spy, four mite piperazines, the pyridaben.
Application Example two:
For trying insect: rice fulgorid.
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
Experimental scheme: effective lethal concentration scope of determining Tolfenpyrad, propargite medicine and the two different proportioning mixture through preliminary experiment.
Toxicity test result one
Table 1 Tolfenpyrad and the toxicity test of the special different proportionings of alkynes mite to rice fulgorid
As shown in Table 1, the proportioning of the special composite control of Tolfenpyrad and alkynes mite rice fulgorid was at 60: 1 to 1: 60 o'clock, co-toxicity coefficient is all greater than 120, illustrating that both were mixed in the scope at 60: 1 to 1: 60 all shows synergistic effect, especially when Tolfenpyrad and alkynes mite spy's proportioning during at 5: 1 to 1: 15, synergistic effect is more obviously outstanding, test through the applicant, the optimum ratio of finding Tolfenpyrad and alkynes mite spy is 5: 1,4: 1,3: 1,2: 1,1: 1,1: 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, co-toxicity coefficient maximum when the special weight ratio of Tolfenpyrad and alkynes mite is 1: 5 wherein, synergistic effect is the most obvious.
