This virus cannot live in extremely dry conditions. The infected plants should be removed to avoid further infestation. The virus overwinters in many perennial weeds. It is spread by aphids, seeds, and weeds. The virus can reduce yields and fruit quality. Plants infected with the virus have little or no marketable fruit. Tomato plants are usually stunted and have poorly shaped leaves and can cause partial or total crop loss. The virus causes peppers to have severe leaf damage with mosaic and necrotic rings. The virus causes cucumbers to turn pale and gray, become bumpy and oddly shaped, and have a bitter taste. The leaves will die and fall off, leaving part or most of the plant bare. The symptoms on leaves known as "shoestring" effect causes young leaves to appear narrow.
Symptoms include stunted or dwarfed plants, mottling, yellowing, distortion, and wrinkling of the leaves with the edges curling downward, and reduced growth rate and yields. CMV – Cucumber Mosaic VirusĬucumber Mosaic Virus is a world-wide virus disease that affects the growth of cantaloupes & melons, cucumbers, eggplants, gourds, peppers, pumpkins, spinach, squash, tomatoes, and watermelons. The best option is to use disease resistant varieties. Keep the day temperature in the 80's and have proper air circulation in greenhouses. Use drip irrigation instead of overhead sprinklers if possible. Proper tillage practices may be helpful in managing the disease. Plan on using a 2 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in over winter on crop debris. The disease is favorable when temperatures are 59 - 77 F and usually occur when moisture and humidity are very high. The infected plants and vegetables should be removed, burned, or tilled in to avoid further infestation. The scab fungus overwinters on the seed, in crop debris, and in soil. The fungus spores are spread by wind, insects, tools, and workers.
Cucumbers, pumpkins, and squash have sunken spots covered with greenish black velvety fungus.
#Cool breeze crack
The dead leaves crack and eventually fall off the plant.
The leaves become wrinkled and have ragged holes. Symptoms include pale green spots appear on the leaves which turn to gray spots and may have a yellow halo surrounding the lesion. Scab is a world-wide fungal disease that affects the growth of cantaloupes & melons, cucumbers, gourds, pumpkins, squash, and watermelons. Scientific Name: Cladosporium cucumerinum Over ripe cucumbers will have a bitter taste. Pick daily to prevent fruit fromīecoming too large. Harvestingįrequently encourages more production. Snip the stems with garden scissors when cucumbers are 2" long for pickling varieties. Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when Requires fertile soil in a well drained location in the garden. Plants grow 1 ft tall and vines spread up to Maturity, so you can have multiple harvest by growing 2 to 3 weeks apart. Trellised plantsĬan be grown as close as 10" apart. Instead of hills, spacing 24" apart in rows 24 - 36" apart. Plant your seeds in soil,Ģ to 3 weeks after last frost, when soil and air temperature is at least 60 F. So it is best to plant seeds directly in the garden. Cucumbers don't do well if roots are disturbed,
