Six antioxidants were tested in vitro and in vivo against seed-borne
fungi of peanut. Hydroquinone showed a highly significant effect on the growth
of the following fungi: Cephalosporium sp., Fusarium moniliforme, F.
oxysporum, F. solani, Rhizoctonia solani, Sclerotium bataticola and Verticillium
sp. Soaking peanut seeds in a 20 mM water solution of hydroquinone for 12 hours
before planting significantly decreased pre- and post-emergence damping off incited
by all tested fungi. Seedling survival and plant vigor in all treatments, including
the check, was increased.
