Variety, mulch and stage of inoculation effects on incidence of Tomato spotted wilt virus disease in cucumber (Cucumis sativus L.)
Archives of Phytopathology and Plant Protection 42 (6), 579-586
Abstract: Tomato spotted wilt virus (TSWV) vectored by thrips is one of the major diseases affecting cucumber yield. Control of thrips is an underlying factor in its management. A study was conducted to determine the effect of time of inoculation, variety and mulch on disease incidence. Four varieties were inoculated with TSWV at cotyledon, 3 - 4 leaf and flower bud stages in a RCBD experiment replicated four times in a greenhouse. In the field, a 2 x 8 factorial design where two cucumber varieties were raised on seven types of mulches (red, yellow, silver, clear, black, white, and straw) with unmulched plots as controls was used. Variety Marketer was more tolerant to the disease compared to other varieties. Most varieties were generally tolerant to TSWV at cotyledonous but susceptible at 3 - 4 leaf and flower bud stages. Silver and clear mulches significantly suppressed thrip populations, yield and quality under field conditions.
