Studies on wilt disease expression in the presence of Meloidogyne incognita and Fusarium moniliforme in grapevine
AbstractA study on wilt disease expression in the presence of Meloidogyne incognita and Fusarium moniliforme on grapevine cv. Muscat Hamburg was carried out under glasshouse conditions. Growth parameters, viz., shoot length, shoot weight, root length and root weight of vines, were found to be significantly affected by the inoculation of M. incognita and F. moniliforme alone and in combination. Simultaneous inoculation of nematode and fungus resulted in the greatest reduction of shoot length (40.6%) and shoot weight (63.9%). Wilt disease was observed when both M. incognita and F. moniliforme were inoculated or when the fungus was inoculated alone. The per cent wilt disease incidence (35%) was higher in vines inoculated with nematodes a week prior to fungal inoculation.
