Abstract
Abstract Various methods of application of the fungicide procymidone were evaluated for the control of onion white rot ( Sclerotium cepivorum Berk.) in field trials carried out in the 1986–87 and 1987–88 crop seasons. The conventional method of seed treatment followed by foliar sprays (monthly × 4) reduced disease incidence by 71 and 95% (of untreated control) in the respective seasons. When applied as a dispersible granule to the soil surface above the seed immediately after planting, disease incidence was reduced by 89 and 95% respectively. Application of procymidone to the soil surface as a spray gave similar control but induced transient symptoms of phytotoxicity in the young seedlings. A slow release formulation of procymidone applied as a seed dressing was more effective than the conventional formulation for seed dressing, and, when followed by foliar sprays, an 85% reduction in disease incidence was obtained. Iprodione applied as a seed treatment followed by four foliar sprays gave a moderate reduction in disease incidence (42%, 60% in respective trials). Procymidone granular formulations are convenient to apply and highly effective against the disease and offer good commercial prospects.
