新燕灵也称莠非敌、杀非克斯(Suffix),属酰胺类除草剂,是英国壳牌研究有限公司1969年开发的选择性芽及茎叶处理剂。主要用于防除小麦、油菜、紫花豌豆、蚕豆田的野燕麦。通过作物和杂草叶部吸收,并在体内传导,经水解作用产生有活性的分子即脱乙基的酸,进一步代谢为无活性的共轭化合物。在所有禾本科杂草内都先分解成酸,再变成糖的共轭化合物。在作物和杂草之间的选择性取决于有除草活性的酸的降解速度—在小麦体内降解很快,使小麦正常生长;在野燕麦体内则很慢,使酸累积而中毒死亡。特别是在野燕麦各种不同生育期或生长旺盛
Xin Yan Ling, also known as aphids, kill Fei Si (Suffix), is an amide herbicide, is the British Shell Research Co., Ltd. in 1969 to develop selective bud and stem and leaf treatment agent. Mainly used to control wheat, rape, purple pea, broad bean field wild oats. Absorbed through the foliage of crops and weeds and conducted in the body, the active molecule, the de-ethyl acid, is hydrolyzed to further metabolize to the inactive conjugated compound. In all gramineous weeds are first broken down into acids, then sugar into the conjugated compounds. Selectivity between crops and weeds depends on the rate of degradation of the herbicidally active acid - rapid degradation in wheat to normal growth of the wheat; slow in the wild oats, resulting in acid accumulation and poisoning. Especially in wild oats in different growth stages or vigorous growth
