Trials examined weed control, soil quality, tree nutrition, and water use. Also monitored for voles, and testing potential for mulch to host nematodes for control of codling moth larvae. David Granatstein, WSU CSANR, Wenatchee.
Dr. Carol Miles, WSU Mt Vernon Research and Extension Center, and Dr. Pete Bristow, WSU Puyalllup, are investigating organic options to control root rot (Phytopthora fragriae var. rubi). This study is focused on organic root rot control, however all raspberry growers will benefit from new disease management options.
