Effects of Two Additives on Reducing Pesticide and Increasing Efficiency for Control of Rice Stem Borer
-
摘要: 为探究增施农药助剂对化学农药防治的减施增效作用,开展了水稻二化螟的田间试验.结果表明,配施的2种农药助剂都具有减少化学农药用量的作用,并且防效都较好.常量处理、减量30%+酸性电解水处理、减量50%+酸性电解水处理、减量30%+激健处理、减量50%+激健处理的投入产出比分别为1∶18.27, 1∶14.33, 1∶15.17, 1∶18.16, 1∶19.43,减量30%或50%+酸性电解水处理的投入产出比略低于常量处理,减量30%或50%+激健处理的投入产出比与常量处理相当,可实现药剂减施后水稻二化螟的防治效果及保产效果与常规用量时相当.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.
