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 soaked in the soup that configures behind the 5s take out, dry naturally; 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 considered 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 pyrrole aphid ketone is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of the theoretical toxicity index (TTI) of M=pyrrole aphid ketone
Pyrrole aphid ketoneTI * the P of+gamma cyhalothrin
Gamma cyhalothrin
In the formula: M is the mixture of different proportionings;
P
Gamma cyhalothrinBe gamma cyhalothrin shared ratio in composition;
P
Pyrrole aphid ketoneBe pyrrole aphid ketone shared ratio in composition.
Application implementation example two:
Supply the examination insect: cabbage aphid.
Experimental scheme: effective lethal concentration scope of confirming pyrrole aphid ketone, the former medicine of gamma cyhalothrin and the two different proportioning mixture through preliminary experiment.
