Late blight incited by Phytophthora infestansis one of the most widelyspread and economically important disease of tomato. The present investigation was carried out to evaluate the efficacy of different fungicides and biocontrol agents for the management of the disease. Soil application of Trichoderma viride and Pseudomonas fluorescens 15 days before transplanting followed by prophylactic spray of Mancozeb (0.2%) 25 days after transplanting was found effective. Three sprays of fungicides viz., Metalaxyl+Mancozeb (0.2%), Fosetyl-Al (0.2%) and Dimethomorph (0.1%)+Polyram (0.2%) sprayed at regular intervals of ten, twenty and thirty days depending on the disease severity was found very effective in managing the disease.Keywords

Front line demonstration was carried out at farmer’s field of Doddaballapur taluk, Bengaluru Rural district, Karnataka, India to study the fertigation levels and schedules on growth, yield and economic of tomato. The treatments included 3 fertigation levels (T1-60% of recommended dose of fertilizer (RDF), T2 -80% of RDF and T3-100% of RDF) with 3 fertigation schedules (T1-farmers practice 30 equal splits of RDF at every 3 days interval, T2-IIHR practice 37 equal splits of RDF at every 3 days interval and T3-TNAU practice 40 equal splits of RDF at every 3 days interval). The results indicated that fertigation of 100 per cent RD of NPK in 40 equal splits at every 3 days interval upto 120 days after transplanting was found significantly superior in case of growth (plant height 138.83cm), yield attributes (number of fruits per plant 100.83) and fruit yield (71.89t/ha) of tomato. The economic benefits of drip irrigation resulted in maximum gross returns (Rs.3,59,450/ha) and B: C of 2.84 in T3 treatment.Keywords
