(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) is converted into
Logarithm value (x), virulence regression equation is drawn with least square method, and thus calculates every kind of medicine
The value of agent, co-toxicity coefficient CTC is calculated according to the abundant equations of Sun Yun.Computing formula it is following (with
Acetyl worm nitrile is standard agent, and its toxicity index is for 100)：
TI × the P of the theoretical toxicity index (TTI) of M=acetyl worm nitrileAcetyl worm nitrile+Thiacloprid
TI×PThiacloprid
In formula：M is the mixture of different ratio
PThiaclopridIt is thiacloprid ratio shared in the composition
PAcetyl worm nitrileIt is acetyl worm nitrile ratio shared in the composition
Application Example two：
For examination insect：Cucumber blight
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
Experimental design：Determine acetyl worm nitrile and thiacloprid active compound by pilot study and the two is different
Match effective lethasl concentration scope of mixture.
