Weed management in sugarcane ratoon crop

However, under limitations of manpower availability, cost etc. pre emergence application of either of altrazine @ 2.0 kg a.i./ha or metribuzin @ 1.0 Kg a.i./ha (800-1000 litre water/ha) followed by either of 2,4 D Na salt @ 1.0 kg/ha (600-800 of water/ha) or hoeing at 45 days after rationing can be successfully practiced.
