Development and validation of IPM technology for ginger in Garhwal region of Uttarakhand

Intensive survey was conducted in different villages of Tehri district of Uttarakhand to identify the major ginger growing areas, where insectpests and diseases are major problem, to validate the IPM module under field conditions. Consequently, two villages i.e. Pali and Gaind were selected where, rhizome rot, leaf spot, white-grub and rhizome maggot were posing serious threat to ginger cultivation were identified. Therefore, an IPM module was formulated for existing pests problems based on the available control measures in literature against these pests which was further disseminated to the farmers through conductance of demonstrations at the farmers’ field in Tehri-Garhwal area. The results indicated that the IPM program provided 48.19, 63.94, 52.09 and 57.82% control of rhizome rot, leaf spot, white grub and rhizome maggots respectively, over non-IPM practice. Analysis of cost benefit ratio of IPM practice revealed that there was 32.82% increase in yield with net return of Rs. 92.04 thousand per hectare and a B: C ratio of 2.15 over Non-IPM practice. Over all study revealed that the ginger production under IPM situation proved comparatively more economically viable in terms of losses decreased by suppression of pest.
