氟胺磺隆、烯草酮及助剂混配防治甜菜田杂草试验初报

The Control of Weeds in Beet Field by Using the Mixtrue of Triflusulfuron - Methyl, Clethodim and Auxiliaries

在甜菜生育前期，选择苗后甜菜茎叶处理除草剂氟胺磺隆和烯草酮及甜菜除草剂专用伴侣、植物安全解毒剂四种药剂按一定比列和浓度混配应用于甜菜田的除草，试验表明该种混配剂组合对甜菜田甜菜生育前期田间杂草的防治效果较为理想，单子叶杂草株数防效达到96．1％，鲜重防效达到99．5％；双子叶杂草株数防效达到92．1％，鲜重防效达到97．8％。实现了及能有效防除田间杂草，又减少除草剂的施用量的目的。

In the early growth period of sugar beet, four kinds of agents, triflusulfuron - Methyl, elethodim, spe- cial partner for beet herbicide and plant safety antidote were mixed in a certain proportion and used in beet field for the control of weeds. The test shows that this kind of mixed herbicide has effective weed control effect in the early growth period of sugar beet. The monocotyledon weed control effect is 96. 1%, fresh weight control effect is 99.5% ; the dicotyledons weed control effect is 92. 1%, fresh weight control effect is 97.8%. The mixed herbicide can reduce the use of herbicides and also has effective weed control effect in the field.
