A ring-spot disease of gladiolus corms. by Colin Douglas McKeen Download PDF EPUB FB2

Gladiolus hortulanus. Fusarium Rot (fungus – Fusarium oxysporum f. gladioli): Corms decay with a brownish-to-black dry rot of the foliage of affected plants first turn yellow and then brown. Roots are killed. When diseased corms are planted, many may rot before producing plants while other produce weak plants that soon die.

Diseases of Ornamental Plants and their Management Eco-friendly Innovative Approaches in Plant Disease Management Do not replant for one year in fields where the disease has occurred. Possibility of Bean yellow mosaic virus detection in Gladiolus plants by different methods Article (PDF Available) in Journal of Plant Diseases and Protection (1) February with   Oxalis is susceptible to chlorotic ring spot virus transmitted by aphids.

It will not affect the african violet or orchids. If it is worth the effort, isolate the diseased shamrock plant and repot the healthy corms in fresh soil.

As there is no cure, see if the plant will recover on its own if not you gave it a try. I.G. Dinesen, A. van Zaayen, in Advances in Botanical Research, 3 Pathogenic fungi. New techniques, which could be used for rapid large-scale routine detection, are in great need for fungi such as Fusarium oxysporum dianthi and cyclaminis.

Both fungi may occur in plants long before the appearance of symptoms and early detection could prevent spread of the disease.

Daffodils (Narcissus) are popular spring flowerbulbs in Europe, North America, Australia, and New Zealand, and tazetta narcissi are widely grown in China, Israel, and volumes of field-grown cut-flowers are traded, along with forced flowers and pot-grown plants from greenhouses, as well as the bulbs themselves.

Besides the species mentioned above, the virus has been isolated from naturally infected gladiolus and sowthistle (Sonchus arvensis) plants showing yellow rings and line pattern on the leaves (Savino et al., ) and from a number of symptomless weeds (Crepis neglecta, Helminthia echioides, Hypochaeris aetnensis, Lactuca virosa, Urospermum.

The corms are checked for any disease infection and the affected corms are discarded. 37 Curing Curing is one of the essential post harvest operations for successful storage of corms.

The major pests are scales and bugs, which are controlled by spraying malathion @ 2 ml per litre of water. Vegetative buds are present over the surface. At the time of lifting the old corms get exhausted while the new corms are formed along with numerous cormels. Cormels will become flowering grade corms after years depending upon size.

Pieces of corms having growing buds can also be used for propagation. e.g. Gladiolus, Crocus, Freesia, etc. UNIVERSITY OF ILLINOIS LIBRARY AT URBANA-CHAMPAIGN ACES NOTICE: Return or renew all Library Materials.
