You can easily grow yellow round cucumber plants in your home garden or terrace garden. Cucumbers are made up of around 95% water during summer cucumbers make a great way to stay hydrated. It contains Vitamin A, C, and K and is rich in magnesium, potassium, iron, calcium, copper, zinc, and many other nutrients and minerals.

Yellow cucumbers are mild, sweet, cool and crunchy and are excellent for adding to salads and pickles.

A heavy population of chickweed alongside CMV infected spinach crop.South yellow cucumber is also called lemon cucumber because it is yellow and round like lemon but these cucumbers do not have citrus flavor their taste is almost the same as that of other varieties of cucumber. Older CMV infected spinach with a greater mottled appearance and puckering.įigure 3. Yellowing and puckering of spinach leaves infected with CMV.įigure 2. Finally, there are several commercial spinach varieties that are resistant to CMV that should be considered for use: Avon, Renegade, Winter Bloomsdale, Melody F1, Menorca, Butterflay, Virginia Savoy, Bloomsdale Savoy, Early Hybrid #7, Marabu RZ, and Unipak 151.įigure 1. There are several aphicides that can be used to control aphids on spinach that can be found in the 2022-2023 Mid-Atlantic Commercial Vegetable Production Recommendations guide. Growers need to scout for aphids and manage this pest early, so that populations do not build to high levels. Organic growers can use row covers to protect spinach plants from aphids and virus transmission. Winter annual weeds like chickweed need to be eliminated from the HT or the field before planting and this weed management needs to be maintained throughout production of the crop. The worst-case scenario would be to have heavy weed pressure in the field or a high tunnel along with a high aphid population (Figure 3). Vegetable hosts include carrot, celery, cucurbits, legumes, lettuce, onion, pepper, spinach, and tomato. These infected weeds often show no virus symptoms. Some of the more important weed hosts include bur- and wild-cucumber, catnip, chickweeds, clovers, curly dock, dandelions, fleabane, flowering spurge, groundcherries, horsenettle, jimsonweed, milkweed, pigweed, pokeweeds, nightshades and white cockle. CMV can overwinter in many weed species and can survive the winter in the roots of a weed and move to the aerial parts in the spring, where it can then be transmitted by aphids to other plants. The virus can also be spread by cucumber beetles and by cultivating and handling plants. The virus is vectored by 75 different aphid species in a nonpersistent manner (meaning that the aphid acquires the virus within a minute of feeding on an infected plant but does not remain infective for very long). The earlier a plant becomes infected with the virus the more severe the symptoms and damage will be.Ĭucumber mosaic virus is only one of more than 10 virus diseases of spinach, but it is one of the most common and economically important viruses of this crop. As the disease progresses the foliage will show a yellow/green mottle (Figure 2) with stunted and severely damaged crown leaves, and even death of the growing point. The first symptom of cucumber mosaic virus on spinach is a mild yellowing of younger leaves and a strapping or “puckered” appearance with margins of infected leaves rolling downwards (Figure 1). Spinach crops this season have had a hard time, with red legged winter mites, spinach crown mites, leaf miner issues and now plants in high tunnels and in fields with cucumber mosaic virus, (CMV).
