El-MougyNehal El-GamalNadia G. M. Abdel-KaderMokhtar 32020193Background and Objective: Pea plants (Pisum sativum L.) affected severely by several soilborne pathogenic fungi causing root diseases, damping-off, root rot and wilt resulted in serious losses in either plant stand and produced yield as well. The aim of the present study designed to assess the efficacy of some biotic and abiotic agents against the incidence of some roots diseases affects pea plants under field conditions. Materials and Methods: The causal agents of pea root diseases were isolated and identified as Pythium sp., Rhizoctonia solani, Fusarium solani and F. oxysporum, respectively. The efficacy of some bioagents as seed dressing as well as chemical inducers and alga extract of Chlorella vulgaris as foliar spray were evaluated against pea root disease incidence under field conditions throughout two growing seasons. Results: Announced reduction effect on root diseases incidence was recorded at (Chaetomium globosum+organic waste) as seed treatment and (Chitosan+Thyme oil) as foliar treatment followed by salicylic acid, (Potassium di-hydrogen phosphate+Thyme oil) and algal extract treatments, respectively. The fungicides Rizolex-T 50% and Topsin-M70 provided good protection to treated seeds from germination to pods formation stages of pea plants. The produced yield of green pods followed the same trend over untreated control treatment. Conclusion: The promising outcome in the present study demonstrated the activity of bioagents as a seed dressing or foliar spray with chemical inducers treatments which might be recommended for the future use for such management of soil-borne root diseases.]]>Oyarzun, P.J.,1993996175Kraft, J.M.,1994Fusarium wilt of peas (a review).]]>14561567Xue, A.G., T.D.
