Abstract
Horseweed has gained importance in recent years due to reports of the development of herbicide resistance to several modes of action, including glyphosate and paraquat. This new 5-page publication of the UF/IFAS Horticultural Sciences Department presents information about the lifecycle, identification, and management of horseweed in citrus groves. This publication is mainly intended for Florida citrus growers but will also be helpful for Extension agents, crop consultants, and others interested in citrus production. Written by Nirmal Timilsina, Sharpton Toussaint, Camille McAvoy and Ramdas Kanissery.
