Evaluate and adopt Bliss method, the method is one of classical way evaluating mixture effect.The independent joint action concept that Bliss proposes according to it is thought, theoretical lethality P during Mixture Use of Insecticides can calculate with following formula:
P=P
m+P
n(1-P
m)
P
mit is the lethality (%) of the first active component target when concentration is m; P
nthe lethality (%) of target when be the second active component working concentration being n.
If two kinds of active components are being greater than theoretical lethality P with the actual of the rear target of finite concentration mixing, are then judging that two kinds of active components are used in combination under setting concentration and there is synergistic effect, otherwise be then antagonism.
The results are shown in Table 1.
