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。
以a.i.360～900 g/hm2用量，30%丁草胺·乙氧氟草醚水乳劑芽前土壤處理防除甘蔗田間雜草。試驗結果錶明，藥後30天、60天對一年生禾本科雜草和闊葉雜草錶現齣良好防效，在a.i.450～540 g/hm2劑量下，對蔗田雜草防效大于86%，且對甘蔗安全。
이a.i.360～900 g/hm2용량，30%정초알·을양불초미수유제아전토양처리방제감자전간잡초。시험결과표명，약후30천、60천대일년생화본과잡초화활협잡초표현출량호방효，재a.i.450～540 g/hm2제량하，대자전잡초방효대우86%，차대감자안전。
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.
