Abstract:
In the present study, the efficacy of non-conventional chemicals along with commonly used fungicide and biocontrol agent were tested against Alternaria solani, which causes Early blight disease in Potato. The treatments were Trichoderma 5g/l (T1), Lithium Sulphate 1 g/l (T2), Hexaconazole 5% (T3), Oxalic acid 5 ppm (T4), Neam leaf extract (T5) and control (T6). Under in-vitro condition, the maximum suppression of pathogen was found in Hexaconazole 5% (T3), followed by Trichoderma 5g/l (T1), Oxalic acid 5 ppm (T4), Neem Leaf Extract (T5) and Lithium sulphate 1 g/l (T2), as compared to control. Similar trend was also observed in field condition when the treatments were analyzed for Disease Incidence (%) and yield (t/ha) after 75 days of planting.
