摘　　要：选用芽前和芽后两种不同类型的除草剂,以单剂和混配形式筛选防除向日葵列当(Orobanchecumana Wallr)的有效药剂,并确定最佳浓度。结果表明,单剂效果较好的是精喹禾灵,其次是烯禾啶;在药剂较高浓度混配时从中筛选出效果好的有以下组合:草甘膦异丙胺盐+7种除草剂(2.4-D丁酯、精-异丙甲草胺、氧氟.乙草胺、丁.异.莠去津、乙草胺、乙氧氟草醚、氟乐灵)的任一种,防治效果均超过98%;进一步试验结果表明,防治效果好且又经济的混配药剂为41%草甘膦异丙胺盐水剂12 L/hm2+57%2.4-D丁酯乳油1.2 L/hm2、41%草甘膦异丙胺盐水剂12 L/hm2+96%精-异丙甲草胺乳油1.2 L/hm2。Two different types of herbicides,pre-emergence herbicides and post-herbicides,in single and mixed forms,were selected for controlling Orobanche cumana Wallr,and the best chemicals and suitable concentration were determined.The results showed that,the single herbicide with best effect was quizalofop-p-ethyl.The controlling effect of sethoxydim was better.The combination with good effect screened from mixed herbicides with high concentration was the compound mixed with glyphosate and any herbicide in the bracket（2,4-D butyl ester,S-metolachlor,atrazine,acetochlor,oxyfluorfen,Muskmelon） with controlling effect all over 98%;The best concentration of mixed herbicides with good and economic controlling effects was glyphosate 12 L/hm2 ＋ 1.2 L/hm2 57% 2,4-D butyl ester,12 L/hm2 glyphosate ＋ 1.2 L/hm2 96% S-metolachlor.
