Multilocation validation of integrated pest management modules in barley

IPM modules for management of barley diseases and aphids were evaluated at multilocations (Karnal, Kanpur, Dharwad, Ludhiana and Faizabad) under AICW&BIP, consecutively for three years (2008–2010) crop seasons. One set of plots 250 sq m each (25 X 10 m) at row to row distance of 23 cm per treatment was planted by following recommended packages of practices. Out of these, one plot was grown as untreated plot without any pest management practice at sowing or later stages, whereas second plot was sown using treated seeds and was protected from diseases and insect pests by using foliar sprays based on economic thresh hold level (ETL). Teatments applied in protected plots consisted of seed treatment with Vitavax Power @ 3g/kg of seed followed by seed treatment with Gaucho @ 0.06 g a.i./kg of seed at sowing; foliar sprays of Tilt (25 EC) @ 0.1% at the appearance of rusts & foliar blight and repeated after 15 days if need arise till physiological maturity; and foliar sprays of Confidor @ 20 g a.i./ha at the appearance of foliar aphids and later at 15 days intervals till physiological maturity and as per need. In all centres, the incidence of diseases and insects pests reduced in treated plots as compared to untreated plots. The percent increase in grain yield was in the range of 11–30%. There was increase in seed germination and 1000 grain weight in IPM plots compared to non treated plots. Based on multilocation evaluation of IPM modules for three years, the above IPM modules were found effective and are recommended in barley crop protection.
