Soybean cultures, especially those from the Danube Meadow, are very strongly infested with Johnson grass, which causes big damages, by the reduction of production with 40-85%, depending on the infestation degree. Before the synthesis of special herbicides for Johnson grass control, this species was controlled by practicing deep tilling, repeated operations with the disk, and, after the sprouting of soy plants, by mechanical and manual hoeings. In the Danube Waterside, the lack of labour force for the manual hoeing is very sharp. For this reason, it was generalized the enlarged use of herbicides for annual weed control (monocotyledonous and dicotyledonous), including Johnson grass. For the control of Johnson grass species, in the conditions of the Danube Meadow, the best results were obtained with the herbicides Fusilade Super, Targa Super, Agil and Select, and for the control of annual dicotyledonous species, with the herbicide Pivot 100LC.
大豆种植，尤其是来自多瑙河草甸的那些，受到约翰逊草的严重侵害，这会造成巨大损失，产量会根据侵害程度降低40%至85%。在合成用于控制约翰逊草的特殊除草剂之前，该物种通过深耕、反复使用圆盘作业以及在大豆植株发芽后进行机械和人工锄草来控制。在多瑙河沿岸，人工锄草的劳动力短缺非常严重。因此，扩大使用除草剂来控制一年生杂草（单子叶和双子叶），包括约翰逊草，已变得很普遍。在多瑙河草甸的条件下，对于控制约翰逊草物种，使用除草剂高效盖草能超级、阔草清超级、炔草酯和精稳杀得可获得最佳效果，而对于控制一年生双子叶物种，使用除草剂百农思100LC效果最佳。
