Problem
Cucumber green mottle mosaic virus (CGMMV) has been an ongoing issue in California since it was first discovered in 2013 The following year, 2014, saw the largest outbreak of the disease, which caused economic losses to seedless triploid watermelon production in four counties. The California cucurbit and seed industries were alarmed at the scope of the outbreak. To try to determine if weed species are hosts for CGMMV and have the potential for carrying over CGMMV between years, we started surveying fields with past detections. This report describes the field conditions during sampling and the testing results.
