1. determine recolonization potential of P. penetrans in broadcast vs. bed fumigated fields; 2. quantify the impact of fumigation treatments and P. penetrans on red raspberry establishment, and; 3. promote implementation of fumigant alternatives through field days, grower meetings, web-based decision-making tools, and printed materials.
We will identify 4-6 fields located in northern Washington raspberry fields and establish replicated plots comparing broadcast fumigation to bed fumigation. In these plots plant-parasitic nematode population densities, plant establishment and plant growth will be monitored over a multiple year period. In collaboration with WSU extension, written and web-based materials will be created and disseminated that help raspberry growers navigate the new EPA fumigation requirements.
