摘要:

为探究飞防助剂类型与杀虫剂的混配方式对水稻二化螟防治效果的影响,本研究以杀虫剂(10%甲维?茚虫威SC、5%氯虫苯甲酰胺SC和0.8%鱼藤酮SC)、飞防助剂(有机硅助剂、矿物油助剂和卵磷脂助剂)、施药液量(21、24和27 L/hm2)为因素设计了3因素3水平的L9(34)正交试验,通过方差分析(ANOVA)方法对各因素的显著性水平进行了分析。结果表明,在本研究的试验条件下,施药后第14天,杀虫剂对水稻二化螟防治效果有显著性影响(P<0.05),飞防助剂对水稻二化螟防效有极显著影响(P<0.01);在设定的施药液量范围内(21~27 L/hm2),施药液量对水稻二化螟防效无显著性影响。混配方式7(0.8%鱼藤酮SC、有机硅助剂和27 L/hm2施药液量)具有较好的速效性与持效性,施药后第14天的防效达81.45%;混配方式4(5%氯虫苯甲酰胺SC、有机硅助剂和24 L/hm2施药液量)持效性显著,施药后第14天的防效为79.30%。本研究成果可为防治水稻二化螟的药液混配方式提供参考。

Abstract:

To explore the effect of pesticide-adjuvants mixture on the control efficacy against Rice Chilo Suppressalis(walker). This study designed a three-factor, three-level orthogonal experiments with pesticides (10% emamectin benzoate·indoxacard SC, 5% chlorantraniliprole SC and 0.8% rotenone SC), adjuvants(organosilicon, lecithin and mineral Oil) , spray volume (21,24 and 27 L/hm2), referred to the three-factor, three-level orthogonal experimental scheme. And made the blank factor the deviation to analyze its rationality. Analysis of variance (ANOVA) statistical method was used to analyze the significance level of each factor. Duncan's new multiple range test (DMRT) method was used to analyze the order of the influence of different levels of each factor on the control efficacy against Rice Chilo Suppressalis(walker). The results showed that, under the experiment conditions of this research, the mean square value of the deviation factor was smaller than the mean square value of the pesticides, the adjuvants and the spray volume, and the deviation of the orthogonal experiment was within a reasonable range. The main order of the effect of the three factors on the control efficacy of Rice Chilo Suppressalis(walker) was: adjuvants > pesticides > spray volumn. On the 14th day after spraying, pesticides showed a significant effect on the control efficacy (P<0.05) and adjuvants showed a highly significant effect on the control efficacy (P<0.01), and spray volume showed no significant effect on the control efficacy. On the 14th day after spraying, the level 3 of the factor "pesticides" was more effective, in the order of Rotenone > Chlorantraniliprole > Emamectin Benzoate·Indoxacard. The level 1 of the factor "adjuvants" was more effective, in the order of Organosilicon > Lecithin > Mineral Oil. The level 3 of the factor "spray volume" was more effective, in the order of 27 L/hm2 > 24 L/hm2 > 21 L/hm2. Therefore, a preferred pesticide-adjuvants mixture method was 0.8% rotenone SC, organosilicon adjuvants and 27 L/hm2 of spray volume, which had a rapid and long-lasting control efficacy, and its control efficacy in the field reached 81.45% on the 14th day after spraying. Additionally, there was also a satisfactory pesticide-adjuvants mixture method that was 5% Chlorantraniliprole, organosilicon adjuvants and 24 L/hm2 of spray volume. This mixture method also performed well, achieving 79.3% control efficacy in the field on the 14th day after spraying. This study could provide a reference for the optimization of the mixture methods of solutions (pesticides, adjuvants and spray volume) for controlling Rice Chilo Suppressalis(walker).
