AbstractApplication of Burkholderia cepacia and Trichoderma virens , alone and in combinations, against Meloidogyne incognita on bell pepper. Nematropica 31:75-86. Bell pepper ( Capsicum annuum L.) seeds and seedlings were treated with three potentially beneficial microbes, applied alone and in combinations, to compare effects of these formulations on rootknot nematode ( Meloidogyne incognita ) populations and on plant growth in the greenhouse. Individual treatments (applied as seed coatings and seedling drenches) were formulations of Burkholderia cepacia strains Bc-2 and Bc-F, and of Trichoderma virens strain Gl-3. Combination treatments were Bc- F+Gl-3, Bc-2+Gl-3, Bc-F+Bc-2, and Bc-F+Bc-2+Gl-3. At transplanting, pepper seedlings were each inoculated with 10 000 M . incognita eggs or left uninoculated, and harvested 10 weeks later. Nonviable microbe formulations of each individual strain were also applied; these were tested only on nematodeinoculated plants. No treatment consistently affect
