Chemical control of white rot of Welsh onion

Abstract

We tested five fungicides (probenazole, iminoctadine albesilate, fludioxonil, tebuconazole, and boscalid) for the control of white rot (Sclerotium cepivorum) of Welsh onion (Allium fistulosum L.) planted in soil inoculated with the fungus. Two experiments in which each fungicide was applied twice showed that fludioxonil and boscalid gave excellent control.
