Abstract: In order to explore the effect of application of pesticide additives on reducing chemical pesticide and improving efficiency, a field experiment for control of rice stem borer was carried out. The result showed that the two pesticide additives can reduce the dosage of chemical pesticides, and increase the control effect. The input-output ratios of constant treatment, 30% reduction with acid electrolytic water treatment, 50%reduction with acid electrolytic water treatment, 30% reduction with stimulation treatment and 50% reduction with stimulation treatment were 1∶18.27, 1∶14.33, 1∶15.17, 1∶18.16 and 1∶19.43, respectively. The input-output ratio of 30% or 50% reduction with acid electrolytic water treatment was slightly lower than that of constant treatment. The input-output ratio of 30% or 50% reduction with stimulation treatment was equivalent to that of constant treatment, which can achieve the same effect on control of rice stem borer and protection of yield as conventional dosage after reducing the application of chemicals.
