Biocontrol by Phenazine-1-carboxamide-Producing Pseudomonas chlororaphis PCL1391 of Tomato Root Rot Caused by Fusarium oxysporum f. sp. radicis-lycopersici

Seventy bacterial isolates from the rhizosphere of tomato were screened for antagonistic activity against the tomato foot and root rot-causing fungal pathogen Fusarium oxysporum f.sp.radicis-lycopersici.One isolate, strain PCL1391, appeared to be an efficient colonizer of tomato roots and an excellent biocontrol strain in an Hair Oils F.oxysporum/t

Complex physicochemical analysis of transformer oil parameters using the inductively coupled plasma mass spectrometry technique

Introduction.Transformers are crucial and expensive components of power systems, experiencing electrical, thermal, and chemical stresses.Transformer oil analysis is important for diagnosing transformer faults and assessing its remaining service life.The oil used in transformers degrades over time due to its interaction with electrical loads and hea
