Watermelon mosaic virus
First discovered in squash.
 Watermelon
mosaic virus is common in temperate regions as well
as in the tropics. It has been reported in most
countries where cucurbits are grown.
Symptoms:
foliar symptoms include green mosaic, leaf rugosity,
green vein banding, chlorotic rings, and
malformation. Fruits are distorted and green spots
can occur, especially on yellow fruit.
Control:
in addition to mineral oil sprays to interfere with
the virus transmissions and insecticides to control
aphid populations,
resistant cultivars can effectively control WMV. |
