Description
本发明涉及农药，具体地说是一种由麦草畏(dicamba)及其盐与烟嘧磺隆(nicosulfuron)组合的防除田间杂草制剂。
本发明涉及的有效成分：
麦草畏(dicamba)
烟嘧磺隆(nicosulfuron)
本发明的目的是给出一种对田间单、双子叶杂草均有较好防除效果的组合除草剂。
本发明的除草剂制剂是由麦草畏及其盐与烟嘧磺隆为有效成分配制的除草混剂，用于一次性防除玉米田发生的单、双子叶杂草。其特征是：按重量配比麦草畏∶烟嘧磺隆为1∶6～40∶1；加入适量助剂或载体，制备成乳油、水剂、水悬浮剂、可湿性粉剂。
本发明的优势：
(1)节约用药成本：本发明提出的组合物，可以一次性防除玉米田苗后大多数单、双子叶杂草，一次施药可控制玉米整个生育期内杂草。节省了农时，同时与玉米田苗后除草剂玉农乐比较，亩成本从15～20元/亩，降到10元/亩，大大节约了用药成本。
(2)扩大杀草谱：麦草畏单用对玉米田双子叶杂草防效较好，对单子叶杂草防效较差。烟嘧磺隆单用对玉米田单子叶杂草防效较好，对双子叶杂草防效较差，但两者混用表现出显著的增效作用，对单、双子叶杂草均有较好防除效果，可以一次性防除玉米田中单、双子叶杂草，一次施药可控制玉米整个生育期内杂草。
(3)对当茬玉米和后茬作物安全：经试验验证，本发明提出的组合物，按正常田间用量的倍量施用，不但对当茬作物玉米安全性很好，而且用药后对后茬种植的小麦等作物均安全。
本发明部分实施例：
实例1(可湿性粉剂)：
麦草畏1％，烟嘧磺隆6％，填充剂88％，助剂5％，制成7％可湿性粉剂。
实例2(水悬浮剂)：
麦草畏5％，烟嘧磺隆1％，填充剂20％，助剂14％，水补足100％，制成6％水悬浮剂。
实例3(乳油)：
麦草畏9％，烟嘧磺隆1％，助剂5％，溶剂85％，制成10％乳油。
实例4(水剂)：
麦草畏39％，烟嘧磺隆1％，助剂15％，水45％，制成40％水剂。
本发明的实施例制剂除草试验效果见下表：
| 处理药剂 | 用量(gai/ha) | 对马唐、牛筋草、狗尾草防效(％) | 对反枝苋、马齿苋防效(％) | |
| 实例1药剂 | 36 | 96 | 88 | |
| 实例2药剂 | 108 | 98 | 97 | |
| 实例3药剂 | 165 | 95 | 95 | |
| 实例4药剂 | 180 | 68 | 94 | |
| 对照药剂 | 百草敌 | 216 | 41 | 92 |
| 烟嘧磺隆 | 36 | 94 | 81 | |
以上处理对玉米均安全。
