Abstract
Alternaria cassiaeJurair and Khan applied as conidia at 1 × 105spores/ml controlled 100% of sicklepod, and 1 × 106spores/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 resistedA. cassiaeinfection more than the other two weeds, total biomass was reduced significantly in both greenhouse and field tests.
