Symptoms & Signs Early symptoms of spinach blight include chlorosis, wrinkling, and distortion of the leaves. The leaves become extremely thin and roll inwards. The thinning and distortion give them a water-soaked appearance. The virus slows down plant growth and causes mottled patterns on older leaves. Transmission The virus is commonly spread by leafhoppers, cucumber beetles, and aphids. In addition to insects, the virus also spreads by mishandling due to infected tools and human contact during the transfer of plants.
