Abstract

Twelve fungicides, Baycor, Bengard, Derosal, Benomyl, Captan, Fytolan, Dithane M-45, Tecto, Topsin M, Syllit, Galben M-8-65 and Galben R-4-33 were evaluated in vitro for inhibition of spore germination of Ascochyta rabiei from Cicer arietinum L. Sensitivity of A. rabiei differed according to the fungicides tested, maximum being to Topsin-M (19.96 ?g ml-1), followed by benomyl, Galben R-4-33 and Tecto. Dosage response curves were similar for A. rabiei treated with Bengard, captan, Fytolan, Galben R-4-33 and benomyl. Dosage response curves were steeper on a log-probit basis for A. rabiei treated with Baycor, Galben R-4-33, captan and benomyl.
