The embodiment of the present invention is the method using Toxicity Determination and field test to combine.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 during test five series concentration, is respectively placed in beaker
Standby.Use the method that first leaching leaf is followed by worm, by the blade of the same size not in contact with any medicament in the medicinal liquid 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 repeating examination borer population used is 50, sets blank simultaneously, checks dead borer population in 72h, calculates mortality rate and correction
Mortality rate, tries to achieve virulence regression equation and calculates LC50Value.If comparison mortality rate is more than 10%, then it is considered as invalid test.Calculate public affairs
Formula is as follows:
Insect corrected mortality is converted into probit value (y), and 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.Common poison system is calculated according to the abundant equation of Sun Yun
Number CTC.Computing formula is 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
In formula: M is the mixture of different ratio
PEffective active composition BFor the ratio that effective active composition B is shared in the composition
PTefluthrinFor the ratio that Tefluthrin is shared in the composition
B plants selected from one of Rynaxypyr, fipronil bisamide, flonicamid, bromine cyanogen insect amide, Tolfenpyrad.
