Abstract
Fungicides differed in their effect on linear growth and sclerotial formation of Bottytis fabae Sard. The lethal or inhibitory concetration to mycelial growth differed for the five fungicides tested. Both Ronilan and Sumisclex were inhibitory at 1.0 ug/ml, while Cuprosan and Trimiltox forte were inhibitory at 150 ug/ml and Dithane M 45 was intermediate. Also, the effect on spore germination and germ tube length differed for the different fungicides. Growing B.fabae on increasing concentrations of the tested fungi-cides resulted in isolates resistant to these fungicides, Ronilan (126.52 fold) and Sumisclex (20.54 fold). Resistant isolates, in general, gained dark gray mycelium and sclerotia were bigger and fewer in number.
