Field-grown Bahamian hot chile (Capsicum annuum) from Bixby, OK, showed mild stunting and leaves with mild mosaic or severe stunting and leaves severely chlorotic to necrotic. Tobacco mosaic virus (TMV) or potato virus Y (PVY) was found in plants with milder symptoms. TMV and PVY were found in plants with severe symptoms. Bahamian hot chile plants inoculated with TMV and/or PVY showed symptoms similar to those found in the field. TMV or PVY inoculated singly caused stunting and mosaic. TMV and PVY inoculated together caused severe stunting and systemic necroses. Thus, a synergistic interaction between TMV and PVY in Bahamian hot chile is indicated.
