control require periodic introduction of new herbicides. Imidazo[4,5‐c]pyrazoles, which were considered of interest as potential herbicides, were synthesized and examined for the pre‐emergence, post‐emergence, and post‐transplant control of weeds in rice against broadleaf and grass weed species. The data obtained suggest that some imidazo[4,5‐c]pyrazoles have potential herbicidal activity against a wide range
农业杂草控制中不断变化的问题需要定期引入新的除草剂。咪唑 [4,5-c] 吡唑被认为是潜在的除草剂,合成并检查了水稻中杂草对阔叶杂草和禾本科杂草的出苗前、出苗后和移栽后控制。获得的数据表明,一些咪唑并 [4,5-c] 吡唑对多种杂草具有潜在的除草活性,其中 5- 甲基、5- 硫甲基和 5- 未取代的衍生物最为有效。在 5-甲基磺酰咪唑 [4,5-c] 吡唑和咪唑并 [4,5-c] 吡唑啉酮系列中未观察到除草活性。
