A common practice in the raspberry production system in northern WA is to plant a wheat cover crop prior to or after fumigating soil in the fall. There are many advantages to utilizing a winter cover crop including increased water infiltration and erosion control. However, wheat is a host for the root lesion nematode ( P. penetrans) (Fig. 1). The objectives of an ongoing research endeavor in raspberry are: 1) to determine the role that a wheat cover crop plays in supporting P. penetrans populations during the raspberry renovation process, and 2) how to manage a winter wheat cover crop prior to re-establishing raspberry.
Winter Wheat Is an Excellent Host for Pratylenchus Penetrans
