Abstract

Tomato early leaf blight, caused by Alternaria solani, is one of the most destructive diseases, causing significant losses in tomato production. In the absence of resistant cultivars, the treatment of tomato early blight disease has mainly relied on the use of chemical fungicides. In disease management, the use of biological control agents has been recognised as a viable alternative to chemicals fungicides. Rhizobacteria that promote plant growth are important in the control of plant diseases. Pseudomonads have long been known to promote plant growth while also delaying disease onset. The current study looked at the effects of Pseudomonas fluorescens on tomato early blight disease and the effect on tomato plant yield components. The field experiment was set up in a randomized block design with seven treatments and three replications at the Regional Research Sub-Station (R & L Zone), Bidhan Chandra Krishi Viswavidyalaya, Sekhampur, Birbhum, West Bengal, India, during Rabi, 2016-17 and R
