Tomato chlorotic spot virus (TCSV) is a tospovirus, similar to but distinct from other tospoviruses currently present in Florida. Like these viruses, TCSV is transmitted by thrips and is able to replicate in both the vector and the plant. TCSV was first reported in Florida in 2012 in tomato plants in Miami-Dade and Lee Counties, but it may have been in the state for several years. Prior to 2012, TCSV was only known to occur in Brazil and Argentina. It is not known how this virus was introduced into Florida. This 5-page fact sheet was written by Jane E. Polston, Erin Wood, Aaron J. Palmateer, and Shouan Zhang, and published by the UF Department of Plant Pathology, May 2013. http://edis.ifas.ufl.edu/pp306

Until recently, squash has been the only cucurbit crop seriously affected by the B biotype of the sweet potato whitefly, also known as the silverleaf whitefly, because of the silverleaf disorder induced by feeding of the immature stages (nymphs). However, three viruses transmitted by the whitefly have been identified in watermelon, muskmelon, and squash in Florida since 2004, making whitefly management a priority for most cucurbits. This 8-page fact sheet details the current UF/IFAS recommendations for managing whitefly-transmitted viruses and for delaying the development of resistance to insecticides in the whitefly vector.
