Because of the rapid expansion of flower tissue, application at 3-to 4-day intervals instead of every 7 days (as used in the trial) may improve the effectiveness of these materials and certainly warrants investigation.…”

Seventeeen fungicidal spray treatments were evaluated in the field to determine their efficiency in c~ntrolling flower b~ight. of chrysanth<:ll,1ums. The fungi in the disease complex were Alternarza alternata, Botrytls cmerea, Itersomlla perplexans, Mycosphaerella ligulicola, and Stemphylium vesicarium. Appreciable disease control was obtained with all the fungicides tested. chlorothalonil being the most satisfactory individual chemical; mancozeb ilnd captafol also gave reasonable control. Combinations of two fungicides did not offer any major advantage.

“…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).…”

White rust (causative pathogen Puccinia horiana) is a destructive disease of commercial chrysanthemum crops. A panel of 19 accessions of commercial chrysanthemum near-relatives (four Ajania species, 11 Chrysanthemum species including five accessions of Chrysanthemum indicum) were screened for their reaction to white rust infection in separate greenhouse trials carried out at two independent sites in eastern China, one in 2010 and the other in 2012. The reaction of the accessions to artificial inoculation ranged from immune to highly susceptible. Accessions of Chrysanthemum indicum, C. yoshinaganthum, C. makinoi var. wakasaense, C. nankingense, C. vestitum, C. lavandulifolium, C. crassum, and Ajania tripinnatisecta were immune, and strong resistance was present in C. japonense, C. × shimotomaii, and A. przewalskii. Most of the accessions behaved similarly in the two trials, but two of the C. indicum accessions produced inconsistent results, each being highly resistant in one trial but susceptible in the other. Because wide crosses are relatively easy to achieve in the chrysanthemum complex, these immune and highly resistant accessions represent promising germplasm for white rust resistance breeding.
