Technical Abstract: Tobamoviruses causes severe production loss of economically important crops. These viruses are transmitted via physical contact or through seeds. The virulent nature of two emerging Tobamoviruses: Tomato brown rugose fruit virus (ToBRFV) and Cucumber green mottle mosaic virus (CGMMV) have threatened several economically important vegetable crops in the Solanaceae (tomato, pepper) and Cucurbitaceae (watermelon, cucumber) worldwide. With the lack of a disease resistant cultivar, preventive measures are the best solution to manage the spread of these viruses. In the present study, we focused our efforts in evaluating 16 chemical disinfectants for their effectiveness against mechanical transmission of ToBRFV on tomato and CGMMV on watermelon. Results showed that six disinfectants (Lactoferrin, Virocid, Clorox, Virkon S, Virex and SP2700) under appropriate concentrations generated significant and broad-spectrum activities against the spread of both ToBRFV and CGMMV. In conclusion, identification of common disinfectants against two emerging tobamoviruses in two different pathosystems suggest their potential broader effects against other viruses.
