The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.First 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, then carry out field trial.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, is placed in respectively beaker standby.Adopt and first to soak the method that connects worm after leaf, take out, naturally dry the blade of the same size that does not contact any medicament is soaked 5s in the liquid that configures after, put into insect box, then connect for the examination larva, raise under 25 ℃ of conditions, every processing repeats for 3 times, every to repeat examination borer population used be 50, establishes simultaneously blank, 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 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 thus the value of every kind of medicament.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (take fluacrypyrim as the standard medicament, its toxicity index is 100):
TI * the P of the theoretical toxicity index (TTI) of M=fluacrypyrim
FluacrypyrimTI * P of+active component B
Effective active composition B
In formula: M is the mixture of different proportionings
P
Effective active composition BBe effective active composition B shared ratio in composition
P
FluacrypyrimBe fluacrypyrim shared ratio in composition
B is selected from a kind of in azacyclotin, Bifenazate, fenbutatin oxide, fenpropathrin.
