Symptoms of squash mosaic include mosaic patterns and mottling of the leaf along with deformed fruit.
The virus is vectored by the spotted cucumber beetle (Diabrotica spp.) and other related beetles. The beetles can retain the virus up to 20 days after feeding on an infected plant. The virus is also seed-borne.
Use virus-free seed to eliminate primary inoculum.
