Basil downy mildew (BDM) has the potential to cause significant losses in the greenhouse. Once introduced into the greenhouse, it can be very difficult to manage and eliminate. 


In the past few years, a vast amount of research has been done on understanding BDM biology and controlling it in the greenhouse using different cultural practices. Before reviewing control strategies, however, it’s important to know more about the pathogen, how it survives and spreads, and how to identify its symptoms. 

Andy Wyenandt and Jim Simon of the Department of Plant Biology at Rutgers University offer a closer look here, including control strategies using cultural practices in the greenhouse such as humidity management and ventilation.
