Abstract

Strawberry plots of the everbearing cultivar Tristar were established in each of 2 yr in Ohio. Ground cover between and within rows consisted of plastic, straw, or bare soil. Fruit infected by Colletotrichum acutatum (cause of anthracnose fruit rot) were introduced immediately before a rain episode in all plots except controls (which had no soil cover). Seven days after the rain, fruit disease incidence in row segments within 61 cm of the inoculum source was 0.19, 0.07, 0, and 0 for plastic, soil, straw, and uninoculated control plots, respectively, in 1990; in 1991, incidence was 0.16, 0.07, 0, and 0 for plastic, soil, straw, and controls, respectively
