US: Umass plant pathologists looking for downy mildew infected basil plants
Few fungicides are labeled for herb plants and there are differences in registrations for field grown plants versus greenhouse plants. Copper products, phosphites, azoxystrobin, and mancozeb are labeled for use on basil. Plant pathologists at UMass are investigating methods to control this disease with biological control agents and are interested in collecting live, infected plants from residential gardens, greenhouses and field grown basil. If you think your basil plants are infected, please call or email Dr. Rob Wick at 413.545.1045, [email protected].
