The embodiment of the present invention is the method adopting 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 beaker respectively for subsequent use.Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 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 contrast lethality is greater than 10%, be then considered as invalid test.Computing formula is as follows:
Insect corrected mortality is converted into probit value (y), concentration for the treatment of (μ g/ml) converts logarithm value (x) to, virulence regression equation is drawn with method of least squares, and calculate the value of often kind of medicament thus, calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (take CGA 183893 as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=CGA 183893 of M
cGA 183893+tI × the P of effective active composition B
effective active composition B
In formula: M is the mixture of different ratio
P
effective active composition Bfor the ratio that effective active composition B is shared in the composition
P
cGA 183893for the ratio that CGA 183893 is shared in the composition
B is selected from the one in Nitenpyram, pymetrozine, Nylar, spiral shell worm ethyl ester.
