ELISA Test Kits for ToBRFV (Tomato brown rugose fruit virus)

Tech Note: ToBRFV ELISA Protocol and Performance Summary

This ELISA test is a qualitative serological assay for the detection of Tomato brown rugose fruit virus (ToBRFV) in tomato and pepper leaf and seed.

Tomato brown rugose fruit virus is a resistance-breaking Tobamovirus that causes severe economic losses in solanaceous crops, including Solanum lycopersicum (tomato) and Capsicum spp. (pepper). It causes symptoms typical of Tobamoviruses that include mosaic and chlorosis on the leaves and discoloration and deformation of the fruit. These symptoms decrease yield and render fruit unmarketable.
