The embodiment of the present invention is the method that adopts Toxicity Determination and field test to combine. FirstBy Toxicity Determination, the co-toxicity coefficient after clear and definite two kinds of medicaments are composite by a certain percentage(CTC), CTC < 80 is antagonism, and 80≤CTC≤120 are summation action, CTC> 120 is synergistic effect, on this basis, then carries out field test.
Test method: when test, respectively the mother liquor of each mixed agent is diluted to five series concentration,Be placed in respectively beaker for subsequent use. Adopt and first soak the method that connects worm after leaf, will not contact any medicamentBlade of the same size in the liquid configuring, soak 5s after take out, naturally dry, putEnter in insect box, then connect for examination larva, under 25 DEG C of conditions, raise every processing 3 timesRepeat, every to repeat examination borer population used be 50, establishes blank simultaneously, checks dead in 72hBorer population, calculates the death rate and corrected mortality, tries to achieve virulence regression equation and calculates LC50Value.If the contrast death rate 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 toLogarithm value (x), draws virulence regression equation with least square method, and calculates thus every kind of medicineThe value of agent, calculates co-toxicity coefficient CTC according to the abundant equation of Sun Yun. Computing formula following (withFive fluorine worm hydrazones are standard medicament, and its toxicity index is 100):
TI × the P of theoretical toxicity index (TTI)=five fluorine worm hydrazone of MFive fluorine worm hydrazones+Effective active becomesDivide TI × P of BEffective active composition B
In formula: the mixture that M is different proportionings
PEffective active composition BFor effective active composition B shared ratio in composition
PFive fluorine worm hydrazonesBe five fluorine worm hydrazones shared ratios in composition
B is selected from the one in spiral shell worm ethyl ester, metaflumizone.
Application Example two:
