Abstract

Foliar-applied flutolanil, diniconazole, tebuconazole, and propiconazole were compared to granular PCNB for the control of southern stem rot (Sclerotium rolfsii) and their effects on yield of peanut in 1988 and 1989 in southeastern Alabama. Numbers of stem rot loci were significantly decreased and yields were increased in plots treated with banded and broadcast applications of flutolanil, diniconazole, and tebucnzole. While yields of flutolanil-, diniconazole-, and tebuconazole-treated plots were significantly higher than the PCNB-treated plots, efficacy of these fungicides in controlling southern stem rot differed only in one of two years. Banded applications of flutolanil gave similar disease control but yielded less than broadcast applications of the same fungicide. Disease control and yield response with propiconazole was comparable to that obtained with PCNB in one of two years and proved far less efficacious against stem rot than the other fungicides evaluated.
