摘要: 对抗咪唑啉酮类除草剂向日葵新品种—新世1号,于向日葵4-6叶期、6-8叶期、8-10叶期,分别喷施5%咪唑乙烟酸水剂、4%甲氧咪草烟水剂750,1500,2250,3000 mL/hm^2,兑水450 L//hm^2,施药后20 d、35 d调查,对向日葵列当均有良好的防除效果.其中在向日葵4-8叶期,最低用药量750 mL/hm^2茎叶喷雾处理,对向日葵列当的防除效果达100%,而且对向日葵安全.

Abstract: In order to verify the control eflects of Imidazolinone (IMI) herbicides application to the sunflower broomrape (Orobanche cumana Walln) on Xinshiyihao,which a novel IMI-resistant sunflower variety. 5% Imazethapyr (AS) and 4% Imazamox (AS) were applied at the dosage of 750,1 500,2 250,3 000 mL/hm^2 based on 450 L water/hm^2 at 4-6 leaf stage, 6-8 leaf stage, 8-10 leaf stage of sunflower respectively. According to the parasitism investigation results at 20 clays and 35 days after herbicide application, the sunflower broomrape were well controlled. The best control effect (100%) was achieved in the case of herbicide was applied at the dosage of 750 mL/hm^2 and at the 4-8 leaf stage of sunflower growth, and it is safe to sunflower.
