The embodiment of the present invention is the method being combined using Toxicity Determination and field test.First pass through indoor virulence to survey
Fixed, after clear and definite two kinds of medicaments are compounding by a certain percentage co-toxicity coefficient (CTC), CTC ＜ 80 is antagonism, 80≤CTC≤120
For summation action, CTC ＞ 120 is potentiation, on this basis, then carries out field test.
Test method：Respectively the mother solution of each mixed agent is diluted to five series concentration during test, is respectively placed in beaker
Standby.Using first soaking the method that leaf is followed by worm, by the blade of the same size not in contact with any medicament in the medicinal liquid having configured
Take out after soaking 5s, naturally dry, put in insect box, then connect for examination larva, raise under the conditions of 25 DEG C, often process 3
Secondary repetition, often repeats test worm number used and is 50, set blank simultaneously, check dead borer population in 72h, calculate mortality rate and correction
Mortality rate, tries to achieve virulence regression equation and calculates LC50 value.If comparison mortality rate is more than 10%, it is considered as invalid test.Calculate
Formula is as follows：
Insect corrected mortality is converted into probit value (y), concentration for the treatment of (μ g/ml) is converted into logarithm value (x), with minimum
Square law draws virulence regression equation, and thus calculates the value of every kind of medicament.Calculate common poison system according to the abundant equation of Sun Yun
Number CTC.Computing formula following (with Tefluthrin as standard agent, its toxicity index is 100)：
TI × the P of theoretical toxicity index (the TTI)=Tefluthrin of MTefluthrinTI × the P of+effective active composition BEffective active composition B
