Interpretive Summary: Tomato necrotic streak virus (TomNSV) is a recently described new species infecting tomato in Florida. Genomic and biological characterization were completed in the current research. Results indicated that TomNSV is the causal agent of necrosis of leaves, petioles and stems, and necrotic rings or spots on fruits, observed in Florida since 2013.

Technical Abstract: Tomato necrotic streak virus (TomNSV) is a recently described ilarvirus that was detected in tomato in Florida. The full TomNSV genome sequence revealed it to be a novel subgroup 2 ilarvirus with little nucleotide identity to other previously reported tomato-infecting ilarviruses. Experimental host range, seed transmission and movement of TomNSV have been examined. This report provides an overview of this emerging virus for growers, Extension workers, crop consultants, and research, regulatory and industry scientists.
