Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Nematology Summary: In a preliminary study, nine commercially available bioagents were tested at three concentrations for their effectiveness in suppressing Meloidogyne incognita. Paecilomyces fumosoroseus@5ml/L proved the most effective while VAM+Bacillus megaterium @20ml/L was the worst. Of the previously scanned nine bioagent products, two were selected for another study. That was testing the capability of four concentrations of the bioagents at four different application times. The density 20ml/L a week prior to transplanting of each of the two bioagents achieved satisfactory results regarding galling and eggmasses reduction. The joint application of animal manures along with botanically originated manures either before or after transplanting was involved in our study. Generally, higher reduction in galling and egg-masses was achieved through pre-transplanting treatments than in case of post- transplanting ones. neem+pigeon litter was the best of all pre-transplanting treatments. In case of post transplanting treatments rabbit droppings+garlic performed best among the rest of the applied treatments.Applying bioagents as seed dressing followed by soil drench was also of our concerns. Seed dressing with B. thuringiensis followed by one soil drench gave lowest galling and eggmasses. Little response was observed in vegetative parameters but not for root weight.Seedling coating with bioagents followed by soil drench, was another understudied delivery technique of bioagents to soil. Seedling coating with Trichoderma album followed by one soil drench yielded best galling reduction, while egg masses were reduced in response to seedling coating with Bacillus thuringiensis followed by two soil drenchs. Synchronized application of bioagents and ample amounts of certain Nematicides was also under trial. Generally, the bioagents almost performed better in case of 0.25 mg nematicide
