The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is 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, after the blade of the same size that does not contact any medicament is soaked to 5s in the liquid configuring, take out, naturally dry, put into insect box, then connect for examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times, every to repeat examination borer population used be 50, establishes blank simultaneously, in 72h, 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:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value to (x), with method of least squares, draws virulence regression equation, and calculates thus the value of every kind of medicament.According to the abundant equation of Sun Yun, calculate co-toxicity coefficient CTC.Computing formula following (take Spiromesifen as standard medicament, its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=Spiromesifen of M
spiromesifentI * P of+effective active composition B
effective active compositionb
In formula: the mixture that M is different proportionings
P
effective active compositionb is effective active composition B shared ratio in composition
P
