摘要: 向日葵田杂草危害,严重影响其产量和品质,人工防除费工费时,而且劳动成本高,生产中没有理想的茎叶处理防除向日葵田一年生单双子叶杂草的药剂。2007年引进国外抗咪唑啉铜类除草剂向日葵品种——美洲虎,应用甲氧咪草烟·咪唑乙烟酸4.8%AS 66.7 m L/667m2~200 m L/667m2茎叶喷雾处理。施药后40 d调查,结果表明,该药剂对田间一年生单双子叶杂草综合株防效达88.1%~99.9%,其中83.3 m L/667m2、100 m L/667m2用药量处理对供试向日葵既安全,又具有较好防效。

Abstract: The occurrence of weeds in sunflower field brings severe yield loss and quality deterioration to sunflower seeds product. In practice, artificial weeding need more labor and higher cost, and there is no suitable foliar-applied herbicide for annual weeds in sunflower fields. In 2007, we introduced an herbicide resistant sunflower hybrid--Jaguar, and used 4.8%Imazamox-Imazethapyr(AS) as foliar-applied herbicide on it. In this study, the test herbicide was sprayed at the dosage between 66.7 m L/667m2 and 200 m L/667m2.Results showed that the control efficacies of test herbicide were from 88.1% to99.9% 40 days after spraying. When applying dosage were 83.3 m L/667m2 and 100 m L/667m2, it kept effective and safe to sunflower.
