Liu Ting, Guangyuan City, Sichuan Province, via text message (133****3944) July 15 Q: We have a lot of moss in rice fields here. How can we prevent it? Shandong Shengbang Greenfield Chemical Co., Ltd. Product Manager Wang Chongguo A: Moss belongs to aquatic weeds and is usually closed with a pre-emergent herbicide. Once it emerges, it is difficult to control. After seedling, it can recommend 56% dimethyltetrachlorobenzene 100-150. Ml/mu, or 20% chlorofluoroacetic acid 50-60 ml/mu, and 48% 200-mercury pine 200-250 ml. In addition, there is no other good way.
