Orange Crisp Watermelon Seeds

FW – Fusarium Wilt

Scientific Name: Fusarium oxysporum

Type: Fungus

Fusarium Wilt is a fungal disease that affects the growth of cantaloupes & melons, cauliflower, eggplants, peas, peppers, squash, tomatoes, and watermelons. It is one of the most devastating of all soil-borne diseases. It attacks the roots of the plants and moves up the stems. Symptoms include stunting and wilting. Plants don’t always die, but it slows growth and reduces yields. Infected seedlings will damping off, wilt, and die. If you stick with fusarium wilt resistant tomato varieties you don’t have to worry. Many of the older heirlooms don’t have any resistance to the disease, so if you grow these then you should keep an eye out for it. The infected plants should be removed to avoid further infestation. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil for 7 years. The best option is to use disease resistant varieties.

WMV – Watermelon Mosaic Virus

Type: Virus - Potyvirus

Watermelon Mosaic Virus is a virus disease that affects the growth of cantaloupes & melons, cucumbers, gourds, pumpkins, squash, and watermelons. Watermelon mosaic virus is primarily a problem in the southern and western regions of the United States. Symptoms include stunted or dwarfed plants, yellow or light green mottling, blistering, marginal yellowing, leaf distortion, and reduced growth rate and yields. Losses of 50 percent or more in yield and fruit quality may occur. The fruit frequently show color breaking and warts. It is only spread by aphids. Symptoms usually begin to show in June. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Plastic mulches have been shown to reduce losses. Insecticides for aphids are of limited value to control the disease. The best option is to use disease resistant varieties.
