The cultivated plants are preferably sorghum, cereals, maize, rice and soybeans, and the herbicides are chloroacetanilides or other compounds having herbicidal action.
公式I中的2-苯基嘧啶、2-萘基嘧啶和2-杂环基嘧啶,其中Hal是卤素原子,Q是取代的苯基或萘基基团或是不饱和、部分饱和和/或与苯环融合的杂环,能够保护栽培植物免受除草剂的植物毒性作用。栽培植物首选为高粱、谷物、玉米、稻米和大豆,除草剂为氯乙酰胺类或其他具有除草作用的化合物。
