Calium aparine, with lepyrodiclis holosteodes and in a part of Xinjiang Province of China, brings harm to crops, especially to high-intensity crops, its ratio is not higher than 33%. Now, damage is increasing, its ealier-time growing speed is slower than crops, It can only receive small amount of sun light. It affects crops quality and output. After its bud comes, it can be controlled by herbicides. such as bentazon, MDBA, harmony and their mixed-herbicides, its effct can get 85%.

猪殃殃在新疆部分地区农田危害,与薄蒴草、卷茎蓼等杂草,组成新的群落危害作物,所占比例不超过33%,是密植作物(如春小麦、春大麦、青稞、豌豆和油菜等)的大敌,面积在扩大,密度在增加,危害在加重;前期生长速度慢于作物,中后期生长速度超过作物,因枝多叶茂,将作物覆盖于下,不能通风透光、增加湿度、病害严重、降低作物品质、降低产量.在出苗后或蕾期用除草剂防除效果好,可用排草丹、百草敌、阔叶散及其混剂防除,防效85%以上,可控制其危害.

The weed seeds of Echinochloa crusgalli, Eclipta Prostraia and Monochoroa vaginalys in the rice field were cultured with rice sceds in an illuminating incubator. Twenty seeds of each weed and ten rice sceds were sown in 9 cm-diemeter petri dish, which 5 ml Hoagland's nutrient solution was added to. After culturing for 1 day, the mixed herbicides were sprayed in each dish in the amount equally used for 1 hm2,with a 1 ml-injector.

The weed seeds of Echinochloa crusgalli, Eclipta Prostraia and Monochoroa vaginalys in the rice field were cultured with rice sceds in an illuminating incubator. Twenty seeds of each weed and ten rice sceds were sown in 9 cm-diemeter petri dish, which 5 ml Hoagland's nutrient solution was added to. After culturing for 1 day, the mixed herbicides were sprayed in each dish in the amount equally used for 1 hm2,with a 1 ml-injector. After maintaining for another 7 days, the Symptoms of root and leaf injury of weed seedling were recorded. The result showed that Mixture Ⅲ had an obvious synergized action over Butachlor used singly. Compared with Oxadiazon, the synergized action was not significant, but the safety to rice seedlings was greatly increased.
