Pseudomonas fluorescens for the Management of Late Leaf Spot in Groundnut

Control of groundnut late leaf spot disease in in vivo conditions revealed that the treatments involving fungicidal spray with combination of carbendazim (0.1%) + mancozeb (0.2%) and seed treatment with Pseudomonas fluorescens (@ 10 g/kg) + soil application of P. fluorescens (@ 2.5 kg/ha at 30 and 45 days after sowings) were found superior in reducing late leaf spot per cent disease index (25.8 and 34.1). The treatment involving seed treatment with P. fluorescens + soil application with P. fluorescens recorded more pod (891 kg ha⁻¹), haulm yield (1495 kg ha⁻¹) and root length (10.1 cm) besides highest benefit cost ratio of 2.2 than other treatments.
