![]() ![]() ![]() Significant temperature and inoculum concentration effects were found.Ī higher temperature and a higher inoculum concentration gave a higher disease incidence.īoth parameters can be manipulated to influence the time course of an assay. Botrytis Blight (Botrytis gladiolorum) Corms exhibiting symptoms of Botrytis. Significant corm cleaning effects were found.ĭehusking and disinfection of the corm gave a significantly higher infection level.įor further tests corm cleaning is not advised, since by damaging the corm secondary infections may occur. Gladiolus diseases and disorders 5Ò¯ 2g ¬vgzZVc g FÅwYÆ åH G. The corm size had no significant effect on the level of Fusarium infection. No cultivar by treatment interactions were detected.Ī significant corm origin effect was also found.įor VCU purposes, corms from different growers (mostly breeders), must be cultivated during one year under equal conditions. In all our experiments, a significant cultivar effect was found. The disease incidence of a number of cultivars with differing Fusarium resistance was assessed with various corm treatments. Therefore this was investigated in the present study. Gladiolus is a genus of ornamental perennial flowering plants in the iris family, Iridaceae. No information about effects of corm origin, corm size, corm cleaning, temperature or inoculum concentration is known.įor Values for Cultivation and Use purposes (VCU) more information is needed about these conditions. Most active in humid conditions, this disease may spread to your plants through traveling spores or may already exist in your soil. The resistance level is determined six to eight weeks after planting, by calculating the relative length (RL) of the shoots, i.e., length of shoots in infested soil divided by length of shoots in control soil. The disease botrytis blight, caused by the fungal pathogen Botrytis cinerea, may infect your gladiolus plants. To assess the Fusarium resistance of cultivars for breeding purposes a standard assay is in use at CPRO-DLO. Resistant cultivars are therefore much desired and partial resistance was found within the commercial gladiolus assortment. gladiolorum are important pathogens of flower bulbs and are the causal agents of leafblight in tulip, lily, and gladiolus, respectively. Botrytis On Gladiolus Plants: How To Control Gladiolus Botrytis Blight. Cultivation of both corms and flowers is hampered by this fungus. ![]() gladioli is the most important pathogen of Gladiolus. ![]()
