one of the growth limiting factors of onion plants is root and basal plate rot disease, caused by fusarium oxysporum f. sp. cepae. in this research, eight iranian onion genotypes, azarshahr red, ghom white, herssin, isfahan dorcheh, kashan white, nishabour ishaghabad, yazd abarkoh, zanjan gholigheseh and two commercial genotypes, texas erly grano and yellow sweet spanish were investigated. geno...
The widespread destruction of commercially grown bulbs of Narcissus tazetta papyraceus (Paper White) has been reported in Israel. This phenomenon is usually characterized by a premature yellowing of the foliage, accompanied by root rot and dark, sunken basal plates. This study confirmed thatAphelenchoides subtenuis is the main cause of the basal plate disease of Narcissus. In contrast to other ...
The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...
many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...
Ghaderi F (2019) Incidence of root and crown rot disease of black cumin in the southwest of Iran. Plant Pathology Science 8(2):1-8. DOI: 10.2982/PPS.8.2.1 Introduction: Black cumin, an annual flowering plant in the family Ranunculaceae, is a medicinal herb with many pharmacological properties. Crown and root rot disease of this plant has been reported in most countries worldwide. This stud...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Rhizoctonia root rot disease is considered as one of the important diseases in sugar beet. Using resistant cultivars decreses production costs, especially application of fungicides and increases the efficiency in controlling of root rot disease. Therefore, growing of resistant cultivars is considered the best approach for disease control. To achieve this goal and to determine yield potential of...
Pink root-rot disease caused by Pyrenochaeta terrestris is one of the serious diseases of onion fields in Iran and the world. The use of resistant cultivars might be a good alternative as suggested on the basis of the screening at the near end of growing season. The susceptibility assessment of 43 Iranian onion clones in glass-house condition in Isfahan for the last two successive years i.e. 20...
