Trichoderma harzianum reduces population of Meloidogyne incognita in cucumber plants under greenhouse conditions
Trichoderma harzianum strain ESALQ-1306 was assessed for its potential biological control against Meloidogyne incognita race 4 under in vitro and greenhouse conditions. In vitro, we noticed 64% of conidial attachment on eggs and second-stage juvenile immobilized by the fungus. In greenhouse, cucumber plants were treated with different concentrations of conidial suspensions before and after inoc...
متن کاملRelationship between Meloidogyne Incognitadensityand Plant Growth of Okra
Root-knot nematodes (Meloidogynespp.) are the most important pests of vegetables, field crops, and ornamental plants. During our previous study, twenty eight okra cultivars were examined against resistance and Pusa Swami was ranked the most susceptible. The purpose of this study was to investigate the effects of increasing initial population density (Pi) of M. incognita on nematode reproduction...
متن کاملEffects of Nematicides and Herbicides Alone or Combined on Meloidogyne incognita Egg Hatch and Development.
The effects of nematicides carbofuran (C) and fenamiphos (F) and herbicides metribuzin (M) and trifluralin (T), alone and in combination, on hatching, penetration, development, and reproduction of Meloidogyne incognita race 3 were determined under laboratory conditions. To study hatching, entire egg masses were exposed to nematicides (6 mug/ml), herbicides (0.5 mug/ml), and their combinations o...
متن کاملInfluence of Glomus intraradices and Soil Phosphorus on Meloidogyne incognita Infecting Cucumis melo.
The interaction among Glomus intraradices, Meloidogyne incognita, and cantaloupe was studied at three soil phosphorus (P) levels in a greenhouse. All plants grew poorly in soil not amended with P, regardless of mycorrhizal or nematode status. In soil amended with 50 mug P /g soil, M. incognita suppressed the growth of nonmycorrhizal plants by 84%. In contrast, growth of mycorrhizal plants inocu...
متن کاملcomparative effects of poultry manure, cow dung, and carbofuran on yield of meloidogyne incognita-infested okra
the effects of poultry manure and cow dung in comparison with the nematicide, carbofuran on the yield of okra infested with root-knot nematode meloidogyne incognita race 2 were investigated. two plots of 17×11 m, each naturally infested with the mentioned nematode, were selected for the study. treatments were poultry manure and cow dung each at the rates of 5 and 10 t ha-1, carbofuran 3g at the...
