止其他莠草大量侵入经处理的地区。阿米特洛耳能有效地控制双穗雀稗和野牡丹,从而可能使土壤长期裸露,给其他莠草以侵入的机会。帕拉夸特对奥图草也有相似的作用。侵入除莠剂有效处理过的地区的莠草中,最突出的是阔叶波利亚草、纤毛醉蝶花、米甘草和白茅。 Only a large number of other weeds invade the treated area. Amitripts effectively control both Paspalum and Wild Peony, potentially exposing the soil to long-term exposure to other weeds. Paraquat has a similar effect on the grass. Of the weeds that invaded areas where herbicides were effectively treated, the most prominent species were Broad-leaved Polygamy, Clyopsis sp., Glycyrrhiza glabra, and Imperata cylindrica.
