Evaluation of pre and post emergence herbicides for effective weeds control in Ginger

Abstract

A field experiment was carried out at Horticultural Research Station, Chintapalli to find out efficient and economic weed management practices for ginger under High altitude and tribal zone of Visakhapatnam condition. The experiment was conducted during Kharif 2012-13 to 2016-17 in randomized block design with twelve treatments and three replications. Pre emergence application of oxyflurofen 0.30 kg/ha at 2 days after sowing followed by post emergence application of quazilophop ethyl 0.05 kg/haat 30 days after sowing followed by hand weeding at 90 days of crop stage is effective and economical for weed management in ginger crop with significantly recorded high fresh rhizome yield (22.79 t/ha) with B:C ratio of 2.96 and was on par with hand weeding at 30, 60, 90 and 120 DAS, which recorded the highest fresh rhizome yield (23.85 t/ha). Uncontrolled weed growth reduced rhizome yield by 88%.
