Manual slashing was compared with three doses of Glyphosate, Paraquat in combination with 2,4-D Na salt as well as Paraquat alone and two levels of 2,4-D. It was observed that paraquat (0.43kg a.i/ ha) + 2,4-D (1.0 kg a.i/ha) and 2,4-D(1.0kg a.i./ha) gave significantly better control. Seven rounds of spraying during the period of observation (692 days) were required for effective weed control. Economic analysis of the different treatments revealed that application of 2,4-D (1.0kg a.i/ha) costs only Rs.4649/- as against Rs.16557/- for manual slashing. It is therefore concluded that growth of M. bracteata on the planting strips can be effectively and economically controlled with the use of 2,4-D.
