The cucumber mosaic virus cannot withstand drying or persist in the soil. The cucumber mosaic virus overwinters in perennial weeds and may be transmitted to healthy plants by aphid vectors although tomatoes are not the preferred host of aphids or by mechanical means. Cucumber green mottle mosaic virus CGMMV is an important seed-borne virus that has caused serious losses in cucurbit mainly cucumber and melon crops throughout Asia Europe the Middle East and North America.

It can even over-winter in perennial and weed roots returning with the new growth in the spring. Cucumber mosaic disease was first reported in North America around 1900 and has since spread worldwide. Expect damage whenever susceptible plants are growing well in spring and summer.

The yellow patches on leaves turn to brown as the disease advances. Soil seed starter pots and containers can be infected and pass the virus to the plant. Mosaic virus overwinters on perennial weeds and is spread by insects that feed on them.
