The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker subsequent use respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 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 the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
The insect corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with the pyridine of epoxy worm is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of the theoretical toxicity index (TTI) of M=epoxy worm pyridine
The pyridine of epoxy wormTI * P of+active component B
Active component B
In the formula: M is the mixture of different proportionings;
P
Active component BBe active component B shared ratio in composition;
P
The pyridine of epoxy wormBe epoxy worm pyridine shared ratio in composition.
Annotate: active component B is a kind of arbitrarily in chlopyrifos, dichlorvos, the malathion.
