Cyclopyrimorate(CAT:I006339) is a novel 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide developed for effective weed management in rice cultivation. It disrupts the HPPD enzyme, a key catalyst in plastoquinone and tocopherol biosynthesis, ultimately leading to chlorophyll depletion and plant bleaching. Cyclopyrimorate shows strong activity against a broad spectrum of annual and perennial weeds, including resistant biotypes, while maintaining high selectivity and safety for rice crops. Its unique chemical structure and mode of action make it valuable in integrated weed management programs. Cyclopyrimorate is also a useful tool in research focused on HPPD enzyme inhibition, herbicide resistance, and crop protection strategies.
