Integration of Myrothecium roridum and 2,4-D in waterhyacinth management

Sub-lethal doses of the commonly used herbicide 2,4-D had no adverse effect on in vitro mycelial growth and in planta damage by Myrothecium roridum on waterhyacinth (Eichhornia crassipes ). Efficacy of M. roridum as a biocontrol agent of waterhyacinth was augmented when used sequentially with low rates (5-10% recommended rate) of 2,4-D both under greenhouse and field conditions.
