Abstract
Pyroxasulfone is a new herbicide developed by Kumiai Chemical Industry Co., Ltd. It has been registered in several countries for use in corn, soybeans, cotton, and wheat. Growth inhibition tests, greenhouse tests, and a field trial were conducted to evaluate the herbicidal efficacy of pyroxasulfone. Pyroxasulfone exhibited an excellent herbicidal activity at lower application rates as compared to S-metolachlor and has shown sufficient residual activity. Pyroxasulfone is one effective tool for the weed management programs.
