Mandi/Kullu: High temperature and drought has started giving heartburns to apple farmers who own orchards in the south sunny face as they are facing moth attack on the fruit crop since last week. This has damaged almost 10-20 per cent of crop in some drought-hit areas in Churag-Karsog in Mandi, Dalash-Nirman-Jaban in Kullu and Chopal, Jubbal-Kotkhai, lower Kotgarh-Kumarsain in Shimla district.
