摘要
以a.i.360~900 g/hm2用量,30%丁草胺·乙氧氟草醚水乳剂芽前土壤处理防除甘蔗田间杂草。试验结果表明,药后30天、60天对一年生禾本科杂草和阔叶杂草表现出良好防效,在a.i.450~540 g/hm2剂量下,对蔗田杂草防效大于86%,且对甘蔗安全。
The aim of the present study was to determine the pre-emergence application of 30% mixed butachlor and oxyfluorfen EW at a.i. 360-900 g/hm2 on controlling weeds in sugarcane fields. The results showed good control effect on annual weeds in Gramineae and broad-leaved weeds after 30 and 60 days of spraying. The control efficacy of 30% mixed butachlor and oxyfluorfen EW at dosages of a.i. 450-540 g/hm2 were more than 86%. It was safe to sugarcane at such dosages.
