After cutting apical buds, the axilary buds The rapid emergence of suckers or axillary buds after topping significantly decreases the yield and quality of waterpipe tobaco material. The sucker removal by hand results in increased labor cost. Using Accotab for sucker control was carried out with variety Re Den in the Spring 2011 and 2012 at Tien Lang. Hai Phong.The experimentwas conducted with Accotab concentrations of 1; 1.2 and 1.5% in order to determine the most appropriate concentration for sucker control without affecting yield and quality of the products. Experimental results showed that treatment of Accotab decreased the number, length and weight of axilary buds, but increased the leaf size and productivity of waterpipe tobaco products. Accotab concentration of 1.2% was found most optimal; this concentration brought highest yield (1625 kg/ha) and highest economic efficiency (79.56 million/ha).
