Prospección de las micosis en los invernaderos de Villa del Prado (Madrid) y su incidencia en el cultivo de judía (Phaseolus vulgaris L.)

摘要: SINOBAS, J.; IGLESIAS, C. y GARCIA, A., 1994: Prospect of the fungus diseases at Villa del Prado greenhouses (Madrid) and their incidence in growing peas (Phaseolus vulgaris L.). Bol. San. Veg. Plagas, 20(4): 889-898. The study (Madrid), aims to contribute making up a bean disease list country. soil microbilogical analysis 8 area as well those dry stalks were started September, 1991. stalk isolated inoculated beans climatic chamber temperature 25 °C ( 14 h/day) 16 (10 h/day)k for 50 days. luminosity ranged from 2,500 3,000 lux. results mycoflora associated with roots rhizosphere follows: Fusarium solani, oxysporum, moniliforme, spp., Alternaria sp., Aspergillus Botrytis cinerea, Cladosporium Curvularia Epicoccum Gliocladium Penicillium Rhizoctonia Rhizopus Sclerotia sclerotiorum, Stemphylium Trichoderma Verticillium Pythium Phytopthora sp. most frequent groups found fungi ill axysporum solani. When (cv. Femira ) F. % seeds did not emerge. remaining 82 showed superfitial white root hypocotyl rot, although plants reached normal developement. Symtoms attacking observed inoculations number non-emerged combination solani + oxysporum was inferior that This suggests kind antagonism between pathogens. both dead 20 24 repectively. In rest seeds, deep rotwas also poorer developemt plants. combined R. similar ones produced woth combinations only seems suggest do have any effect on manifestation pathogen power.
