摘　　要：在田间条件下,对沈阳化工研究院创制的除草剂SYP-249的除草效果及对小麦、大豆的安全性等进行了试验研究。结果表明,SYP-249在300-450 g a.i./hm2剂量下对小麦及大豆田中的多种阔叶杂草有较好的防除效果。小麦的5个试验点中有2个试验点在中高剂量下小麦略有减产,其它3个试验点有一定的增产。大豆的5个试验点中均表现出明显的增产作用。SYP-249具有作用速度快、可混性强、对环境友好等特点, 是一个值得深入开发的除草剂新品种。Field trials were conducted to investigate weed control and crop safety for postemergence herbicide of SYP- 249 was a new herbicide product of Shenyang Research Institue of Chemical Industry which had good control of broadleaf weeds and safe for wheat and soybean. The field trials results showed that formulated SYP-249 at 300-450 g a.i./ha provided excellent control of the broadleaf weeds in wheat and soybean field. Among five field trial locations of wheat SYP-249 could improve the yield in three locations. Among five field trial locations of soybean SYP-249 could improve the yield in all the trial locations. SYP-249 had a quick action, strong mix and at the same time had good environment compatible, so SYP-249 is worthy of research and develop.
