Abstract

Alternaria cassiae Jurair and Khan applied as conidia at 1 × 105 spores/ml controlled 100% of sicklepod, and 1 × 106 spores/ml controlled coffee senna in the greenhouse. In the field, sicklepod control did not differ between one or two fungal applications, but coffee senna control increased following two applications. Although showy crotalaria resisted A. cassiae infection more than the other two weeds, total biomass was reduced significantly in both greenhouse and field tests.
