Implementation and Demonstration Report in Integrated Pest Management Microbial Products for Poinsettia Disease Suppression

Abstract

The microbial efficacy trials took place in several commercial greenhouses during the period 1997-2000, funded by the IPM Program and IR-4. We are very grateful for the opportunity to work closely with growers to understand the cultural requirements of the crop and site-specific factors that impact on prevention of root and crown diseases. Together with the growers we stuck cuttings, scouted, transplanted, monitored EC and pH, applied treatments, and sent off samples for diagnosis. We have determined that microbials can be used in combination with early detection, careful diagnosis, and rogueing to improve disease management and reduce the total number of conventional fungicide drenches. This was a very successful project from an IPM perspective, resulting in beautiful poinsettia crops and opportunities to deliver our expanded knowledge in New York state.
