进贤芝麻茎点枯病的药剂防治试验

Chemical Control Trial against Stem Blight of Sesame in Jinxian County

为有效控制芝麻茎点枯病发生。采用不同的处理方法,研究几种防治处理对芝麻茎点枯病的防治效果。结果表明:播种前分别用75%敌磺钠和0.5%硫酸铜对土壤和种子进行消毒处理,苗期、盛花期和盛荚期喷施48%瑞枯霉,盛花期和盛荚期喷雾叶面肥氨基酸对芝麻茎枯病的防治效果最佳,防治效果约为84.49%。播种前对土壤和种子进行消毒并结合苗期、盛花期、盛荚期相应药剂处理能有效控制进贤芝麻茎点枯病的发生。

This study aimed to effective control stem blight of sesame by different chemical treatments. The control efficiency of different chemical treatments on the stem blight of sesame was tested in field. The control efficiency of chemical on the stem blight of sesame was tested in field. The result showed that soil and seeds were sterilized by 75% fenaminosulf and 0.5% copper sulfate before sowing sesame, 48% Rui Ku Mould~ applied to the growth period of sesame （e.g., seedling period, full blossom period and full pod period） and by spraying amino acid （foliar fertilizer） at full blossom period and full pod period of sesame can obtain the best control effect, and the control efficiency get approx 84.49%. The best control effect on blight of sesame by soil sterilize, seeds sterilize and chemical treatments at growth period of sesame （e.g., seedling period, full blossom period and full pod period） in Jinxian County.
