The effect of derivatives of 1,4-oxathiin on Puccinia horiana in chrysanthemum morifolium

Variation for Resistance to White Rust (Puccinia horiana) among Ajania and Chrysanthemum Species

“…Although white rust can be chemically controlled (Dickens, 1990;Zadoks et al, 1969;Zandvoort et al, 1968a), the use of fungicides is associated with both environmental hazards and an increased production cost (Waard et al, 1993); overdependence on their use has already led to the appearance of tolerant strains (Abiko et al, 1977;Cook, 2001). The more sustainable strategy of exploiting genetically determined resistance requires the identification of sources of resistance, as first attempted by Dickens (1968) and Martin and Firman (1970).…”
