All the tested fungicides (benomyl, captafol, chlorothalonil, iprodione, mancozeb, procymidone, thiram, thyophanate-methyl), although with dlfference according to the kind of treatment, limited infections powerfully. Thyophanate-methyl and benomyl in foliar sprays, thyophanate-methyl and chlorothalonil in soil drench, thyophanate-methyl, benomyl and captafol in seed dressing, gave best results. By these results, tha Authors point out that a very good control of pumpkin scab is attainable avoiding primary infections on seedlings by soil drench and se ed dressing
