    氯虫苯甲酰胺200SC防治稻纵卷叶螟及对水稻的增产作用

    Effects of chlorantraniliprole 200SC on Cnaphalocrocis medinalis control and rice yield increase

      摘要
    • 摘要:
      目的 研究氯虫苯甲酰胺200SC大田防治稻纵卷叶螟Cnaphalocrocis medinalis的效果及对水稻产量的影响。
      方法 采用大田试验研究氯虫苯甲酰胺200SC对水稻的保叶效果及对水稻生长的影响，调查施药前后水稻卷叶株数、分蘖数、水稻叶色、千粒质量等生理指标。
      结果 氯虫苯甲酰胺200SC对稻纵卷叶螟具有明显的防治效果，并能够促进水稻有效分蘖、减少无效分蘖、增加每穗粒数、提高水稻产量，但对水稻叶色、长势及结实率的影响不明显。与空白对照相比，氯虫苯甲酰胺200SC和阿维菌素18EC(阳性对照)分别可使水稻分蘖数提高24.14%和11.24%，有效分蘖数提高2.01%和3.35%，无效分蘖数减少38.06%和40.30%，每穗粒数增加10.23%和4.40%，增产12.72%和7.89%，千粒质量增加2.68%和1.86%。
      结论 氯虫苯甲酰胺200SC处理对稻纵卷叶螟具有明显的防治效果，并对水稻具有增产作用，且优于对照药剂阿维菌素18EC。

       

      Abstract:
      Objective To investigate the role of chlorantraniliprole 200SC in controlling the rice leaf roller, Cnaphalocrocis medinalis, and in rice yield.
      Method The effects of chlorantraniliprole 200SC on protecting rice seedlings and rice growth were studied in four different test sites of Hubei Province using field experiments. Some physiological indicators were measured, such as the number of flag leaf roll rice plant, rice tiller, leaf color and thousand-grain weight.
      Result Chlorantraniliprole 200SC could effectively control rice leaf roller, promote effective tillers, decrease invalid tillers, increase kernels per spike and rice yield, but it had no obvious effects on rice leaf color, growth vigor and seed setting percentage. Compared with the negative control, overall rice seedling tillers per hill increased by 24.14% and 11.24%, with the effective ones increased by 2.01% and 3.35%, and the invalid ones decreased by 38.06% and 40.30% in the field plots treated with chlorantraniliprole 200SC and avermectin 18EC (the positive control), respectively. Compared with the negarive control, kernels per spike increased by 10.23% and 4.40%, rice yield increased by 12.72% and 7.89%, and thousand-grain weight increased by 2.68% and 1.86% in the field plots treated with chlorantraniliprole 200SC and avermectin 18EC(the positive control), respectively.
      Conclusion Chlorantraniliprole 200SC has excellent insecticidal activity which is superior to the positive control avermectin 18EC, and can effectively increase rice yield.
