The effects of metham-sodium (MES) at 35 ml/m2, methyl bromide (MB) at 50 g/m2, and soil solarization (S-S) on viability of sclerotia and production of apothecia of Sclerotinia sclerotiorum, were studied at two irrigated arid sites in Israel. MES, MB and S-S killed sclerotia in the top 10 cm to a similar degree (over 90%) and consequently reduced apothecia production: over 20 times more apothecia were observed in the controls than in the treated plots. © 1988.
