盆栽试验结果表明，甲黄隆用１５～３０ｇ／ｈｍ２、绿黄隆３０ｇ／ｈｍ２在甘蔗苗前作土壤处理对杂草的防效达８３％～９２％，对甘蔗安全；在甘蔗苗后作茎叶处理防效低（６１％～７７％），甘蔗有轻度药害。环嗪酮用５６２５～７５０ｍＬ／ｈｍ２在甘蔗苗前作土壤处理和苗后作茎叶处理防效均达１００％，但前处理对甘蔗安全，后处理对甘蔗有一定的抑制作用。田间试验结果表明，绿黄隆用１５～４５ｇ／ｈｍ２在甘蔗苗后作茎叶处理的防效和持效期均不如莠去津１５００ｍＬ／ｈｍ２，且对甘蔗生长有一定的抑制作用。
The results of pot experiment showed that the control effect of wehlonglong with 15 ~ 30g / hm2 and 30g / hm2 of green Huanglong on soil weed was 83% ~ 92%, which was safe for sugarcane; Leaf treatment with low efficiency (61% ~ 77%), sugar cane mild injury. The control efficacy of hexazinone (5625 ~ 750 mL / hm2) before and after the treatment of stems and leaves of sugarcane seedlings was up to 100%. However, the pretreatment on sugarcane was safe and post-treatment had a certain inhibitory effect on sugarcane. The results of field experiments showed that the control effect and duration of stems and leaves of sugarcane seedling treated with 15 ~ 45g / hm2 were not as good as that of atrazine (1500mL / hm2), and inhibited the growth of sugarcane.
