Abstract
The optimum mixture ratio of screening and co-toxicity coefficient of determination was carried out.The results showed that cyhalothrin: azadirachtin=1∶6 ratio is the best ratio for an ideal mixture products.Field efficacy of their experimental results show that: the optimum dilution ratio mixture concentration was 1 500 times the better control effect of Uroleucon gobonis(Matsumura) and environment-friendly,with a spread value.
