Products effective but note cautions for use PATHOGEN GROUP AFFECTED

Transcription

1 Products are color coded to indicate use recommendation. Green products are approved for use whereas yellow products have limitations and other options should be considered. As will all chemicals, please review the MSDS and other manufacturer s use guides prior to implementation. THIS TABLE IS ONLY A RECOMMENDATION, PLEASE CHECK IF DOSIS AND PRODUCTS ARE AUTHORIZED IN YOUR AREA. Many products have been shown to have good efficacy against Clavibacter michiganensis subsp. michigansensis (Cmm). Kleengrow and Virkon have shown good efficacy against Cmm and would suspect it to also control Aac. Virkon S has shown to have good control against viruses (TMV/ToMV). Better then the quaternary ammonium products. The Quats may be good too but it appears a longer exposure to the product is needed then virkon. Needs validation but Virkon S has shown to be the best against Tobamoviruses (TMV/ToMV) with a short exposure time to the product. Recommend users of any disinfectant should acquire test kits for the product to measure products efficacy. Physan 20, Kleengrow. Virkon S all have test kits to measure activity.
