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 کاملImpact of Meloidogyne incognita on Physiological Efficiency of Vitis vinifera.
Four-week-old French Colombard plants rooted from green cuttings were inoculated with 0, 1,000, 2,000, 4,000, or 8,000 Meloidogyne incognita second-stage juveniles and maintained at 25 C night and 30 C day. Leaf area and dry weight and the rates of photosynthesis, stomatal conductance, and internal leaf CO concentration were measured at intervals up to 59 days after inoculation. Nematode stress...
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...
متن کاملUse of entomopathogenic nematodes to suppress Meloidogyne incognita on greenhouse tomatoes.
Tomato seedlings in a growth chamber were inoculated with 150 Meloidogyne incognita eggs and 25 infective juveniles (IJ)/cm² of Steinernema feltiae, S. riobrave, or Heterorhabditis bacteriophora. With the exception of seedling roots treated with H. bacteriophora, all seedlings treated with entomopathogenic nematodes had fewer M. incognita juveniles inside roots and produced fewer eggs than the ...
