Sunken mottle of Honey Dew melons
The fruit defect, sunken mottle, is a major problem facing Honey Dew growers in the Central Valley. It is an insect-borne malady, apparently caused by watermelon mosaic virus, type 2, according to this study. In recent years it has caused losses of about one-third of the Honey Dew acreage in Stanislaus County. It has been especially severe on late-planted fields. Control of the virus requires knowledge and control of the insect vector and any host plants. The best long-term solution to the problem maybe a breeding program for mosaic-resistant line of Honey Dew melons.
