2011 Annual Report 1a.Objectives (from AD-416) 1. Development of decision-making tools. 2. Develop sustainable management systems. 1b.Approach (from AD-416) Through a combination of laboratory and field experiments we will develop decision-making tools and sustainable management systems for the control of Phytopthora spp. and plant-parasitic nematodes in raspberry production systems. Specifically we will use molecular techniques to characterize and determine virulence of Phytophthora spp. in raspberry. We will establish field trails in nematode-infested fields to identify raspberry plants resistant or tolerant to Pratylenchus penetrans. We will also begin to develop sustainable pest management systems for raspberry by establishing field trials in northern Washington that evaluate alternative was to broadcast fumigation to manage soil borne pathogens prior to establish a raspberry crop.
