Summary: Three chemical methods of clearing pineapple ratoons were compared with the traditional method of cutting and burning after the plants have dried. The best chemical treatment was paraquat at 0.84 kg ha −1 which gave full scorching at leaves on 92% of plants so that they could be easily burnt 3 weeks after treatment. Plants sprayed with diesel oil or kerosene at 570 1 ha −1 could be satisfactorily burnt after 9 weeks compared with 12 weeks required for satisfactory burning with the traditional method.
