Zinc Induced Resistant against Yellow Stem Borer (Scirpophaga incertulas, Walker) in Rice

To confirm the zinc induced resistant against yellow stem borer, a field experiments were conducted during kharif 2022 and 2023 at N. M. College of Agriculture, Navsari Agricultural University, Navsari Gujarat (India). In experiment total eight treatments are given first four are soil application of zinc and next four are foliar application, Overall performance of the zinc treatments over two kharif seasons highlighting efficacy of zinc treatments in keeping the YSB damage in control both at vegetative and heading (reproductive) stages of the rice crop confirmed the superiority of treatment T2 (ZnSO4 @ 50 g/ha), T4 (Zn- EDTA @ 25 kg/ha) and T8 (foliar application of Biosynthesis Zinc nanoparticle @ 100 ppm). At vegetative stage, treatments T2, T4 and T8 recorded numerically the lowest mean borer damage of 6.45, 7.60 and 8.60 per cent DH attributing in 55.61, 47.69 and 40.81 per cent decline in borer damage over control, respectively. While, at the heading stage, similar treatments T2, T4 and T8 recorded numerically the lowest mean borer damage of 7.01, 8.28 and 9.69 per cent DH attributing in 62.63, 55.86 and 48.35 per cent decline in borer damage over control, respectively. YSB damage was significantly and negatively correlated at vegetative (r = -0.64**) and heading stage (r = -0.67**) with zinc content.
