The LC of toxicity index (the TI)=imicyafos of chlorfenapyr50The LC of/chlorfenapyr50×100
The LC of actual toxicity index (the ATI)=imicyafos of M50The LC of/M50×100
TI × P chlorfenapyr of TI × P imicyafos+ chlorfenapyr of theoretical toxicity index (the TTI)=imicyafos of M
TTI × 100 of the ATI/M of co-toxicity coefficient (the CTC)=M of M
In formula:
M is the mixture of chlorfenapyr and imicyafos different ratio
P chlorfenapyr is the ratio that chlorfenapyr is shared in mixture
P imicyafos is the ratio that imicyafos is shared in mixture
(5) toxicity test result and analysis
Table 1 imicyafos, the chlorfenapyr indoor measurement result to diamondback moth
As can be seen from the table, in the mixture of different proportion, its co-toxicity coefficient is all higher than 120, shows certain increasing
Effect effect, wherein imicyafos: chlorfenapyr be 7: 15 potentiation the most obvious, co-toxicity coefficient is 206.84.Result of the test table
Bright, chlorfenapyr, two kinds of medicaments of imicyafos all have higher activity to diamondback moth in room conditions, different proportion proportioning
Result of the test shows, when being 5:17,7:15,9:13,11:11,13:9 by effective ingredient imicyafos: chlorfenapyr, all shows
Stronger potentiation, wherein with imicyafos: when chlorfenapyr is 7: 15, synergistic effect is best.Suggestion is to suitable proportion 7:15
The mixture preparation of left and right scope carries out further field control effectiveness test, to evaluate its field practical application effect.
