Chlorantraniliprole, metaflumizone, chlorfenapyr, ProclaimR (banleptm) and diafenthiuron are common
insecticides used for controlling diamondback moth, Plutella xylostella. In this paper, the experiments of surface tension
test, bioassay analysis in lab, effective duration evaluation in potted and field vegetables were corried out to study the effect
of different formulations (EC and SC) of 5 insecticiedes on P.xylostella. The results showed that surface tension values of all
EC formulations were lesser than SC formulations, and toxicity of all EC formulations against to P.xylostella were also better
than SC formulations. But effect of SC formulations had better stability than EC formulations in the open environment. All
the results indicate that different formulations of the same insecticide have different advantages; we should select the
appropriate formulation according to the different environmental conditions |
