Soil Transmission of Cucumber green mottle mosaic virus and Its Control Measures in Watermelon
Gug Seoun Choi, Jae Hyun Kim, Jeong Soo Kim
Abstract
Soil transmission ratio of Cucumber green mottle mosaic virus (CGMMV) was 0.2 to 3.5% in watermelon growing fields naturally infested with the virus. Biological activities of CGMMV lost after 17 months in moist well-aerated soil but still continued more than 33 months in waterlogged soil. To inhibit the virus infection through soil, the roots of watermelon seedlings were soaked in 10% solution of skim milk prior to transplanting. The seedlings treated with skim milk solution were not infected, while 5.0 to 7.6% out of control seedlings were infected. The roots treated with skim milk were coated with membrane around the roots under scanning electron microscope.
Key Words: Cucumber green mottle mosaic virus, Skim milk, Soil transmission
