Also known as TSWV, this viral disease infects up to 1000 different plant species including ornamentals, vegetables, field crops and weeds. It is carried by at least 9 species of thrips, minute insects with cigar-shaped bodies and weak feathery wings. Symptoms on the leaves include bronze or dark ringspots and upward rolling; on the fruits, yellow ringspots and, less often, brown necrotic sunken areas. Plants may be stunted and young ones may die.
