By Toxicity Determination, clear and definite two kinds of medicaments compound by a certain percentage after co-toxicity coefficient
(CTC), CTC ＜ 80 are antagonism, and 80≤CTC≤120 are summation action, CTC
＞ 120 is synergistic effect, on this basis, then carries out field test.
Test method：The mother liquor of each mixed agent is diluted to five series concentrations respectively during experiment,
It is respectively placed in standby in beaker.Using the method that first leaching leaf is followed by worm, will be not in contact with any medicament
Blade of the same size 5s is soaked in the liquid for having configured after take out, dry naturally, put
Enter in insect box, then connect for examination larva, raised under the conditions of 25 DEG C, often process 3 times
Repeat, often repeat test worm number used for 50, while setting blank, check dead in 72h
Borer population, calculates the death rate and corrected mortality, tries to achieve virulence regression equation and calculates LC50Value.
If the control death rate is more than 10%, it is considered as invalid experiment.Computing formula is as follows：
Insect corrected mortality is converted into probit value (y), concentration for the treatment of (μ g/ml) conversion
Into logarithm value (x), virulence regression equation is drawn with least square method, and thus calculated every kind of
The value of medicament.Co-toxicity coefficient CTC is calculated according to the abundant equations of Sun Yun.Computing formula is as follows
(with propylene glycol alginate as standard agent, its toxicity index is for 100)：
TI × the P of theoretical toxicity index (the TTI)=propylene glycol alginate of MPropylene glycol alginate+ have
TI × the P of effect active component BEffective active compositionB
In formula：M is the mixture of different ratio
PEffective active compositionB is effective active composition B ratios shared in the composition
PPropylene glycol alginateIt is propylene glycol alginate ratio shared in the composition
B is selected from one of imidacloprid, Acetamiprid, CGA 183893, ethiprole and plants.
