Bio-Efficacy and Phytotoxicity of Novel Fungicide Isotianil 7% + Fosetyl Al 70% WG in Pomegranate Against Bacterial Blight (Xanthomonas axonopodis pv. punicae) Disease

The experiment was conducted at Horticultural Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during Kharif-2022 & Kharif-2023, respectively to evaluate the bio-efficacy and phyto-toxicity on the bacterial blight diseases as well as effect of Isotianil 7% + Fosetyl Al 70% WG on the yield of the pomegranate. The disease Intensity per cent of bacterial blight diseases was recorded, before spraying (Pre-treatment) and at 5 and 10 days after each spray (post-treatment). Total pomegranate fruit yield was recorded and converted in to the hectare basis and phytotoxicity observation for yellowing, stunting, necrosis, epinasty and hyponasty, etc. were recorded 1, 3, 5, 7, and 10 days after second spray. The results revealed that the treatment Isotianil 7% + Fosetyl Al 70% WG @ 200 gm per 100 lit. of water and Isotianil 7% + Fosetyl Al 70% WG @ 150 gm per 100 lit. of water showed significantly higher efficacy against bacterial blight disease and gives the higher yield of pomegranate over other treatments during the two consecutive seasons Kharif 2021 and Kharif 2022. The two years data on the Phytotoxicity studies revealed that none of the treatments exhibited any of the phytotoxicity symptoms.
