Plant. Amitrole is transformed in plants to form the conjugate P-(3-amino-l,2,4-triazol-l-yl)-a-alanine (Humburg et al., 1989) and/or 3-(3-amino-5 -triazole-l-yl)-2-aminopropi-onic acid (Duke et al., 1991). Amitrole is metabolized in Canada thistle (Cirsium arvense L.) to three unknown compounds which were more phytotoxic than amitrole (Herrett and Bagley, 1964). In field horsetail, amitrole was absorbed and translocated but degradation products were not reported (Coupland and Peabody, 1981). 

Common/vernacular names Common horsetail, field horsetail, running clubmoss, shen-jincao (E. arvensef, rough horsetail, common scouring rush, and muzei (E. hymale). 

In fields where some weeds were cleared using herbicides, other, more herbicide-resistant, species have appeared, such as common horsetail, coltsfoot, foxtail, wild oats, false wheat, etc. As a result of herbicide use, scratchweed, which cannot be destroyed by any herbicide, is making inroads into cereal crops, and chamomile has taken over rapeseed [6]. Using herbicides on rice fields caused the spread of wild, pesticide-resistant, low-yield forms of red-grain rice. 

Weeds sueh as ragwort, horsetails, nightshade, foxgloves and hemlock are poisonous and if eaten by stock are likely to cause poor growth or even death. Fortunately, most stoek animals normally do not eat poisonous weeds in the field although they will if such plants are eonserved in hay or silage.
