Abstracts |
Tomato (Solanum lycopersicum L.) domestic production is largely below requirements in Côte d'Ivoire because of numerous abiotic and biotic constraints, especially sclerotinia caused by Sclerotium rolfsii. The present study was initiated to test the antifungal activity of a complex consisting of propagules of 6 different species of arbuscular mycorrhizal fungi (AMF) on S. rolfsii. Inoculations with S. rolfsii sclerotia were performed. Green house tomato plants of the 45 day old Lindo F1 variety were transplanted into pots of 297 cm3
volume. The impact of inoculation was assessed at planting and at the end
of the experiment on plant height growth, collar diameter, number of functional leaves and number of flowers. The results revealed that the mycorrhization of nursery plants with the CMAs used has antifungal action on S. rolfsii. Mycorrhization had a beneficial effect on growth, especially in the early phase, when mycorrhizal plants appeared to be better developed than non-mycorrhizal plants. The incidence of dry rot in non-mycorrhizal plants is 2.5 times higher than the incidence of mycorrhizal plants. Mycorrhization may be advisable for growers in tomato growing areas where sclerotinia is more prevalent as an alternative to the over use of synthetic fungicides. |
