Abstract: Neteistoxin oxalate belongs to a new type of insectcide.Based on the results of three years in laboratory and field experiments,it was found that nereistoxin oxalate is a very effective insecticide,especially against rice striped borer(Chilo Suppressalis)and Yellow Stem borer(Tryporyza incertulas).The efficacy of this insecticide,used at the rate of effective ingredient 0.75 kg/ha,is equivalent to carlap,Evisect,dimebypo and bancol,and the mechenism of action is the same.Nereistoxin oxalate is a promising compound to control rice pests which are resistant to oragnochlorine,organophosphorus and carbamate insectcides.
