In a random complete block design with 4 replications and 18 treatments, various control management systems were tested against swallowort (Cynanchum acutum) in an arachis orchard. Treatments included: spraying with paraquqt (20% SL) 3 times, cutting of swallowort 3 times, spraying with 2, 4, and 6 L/ha glyphosatr (41% SL) plus 8 kg/ha ammonium sulphate for 3 times, spraying with 2, 4, and 6 L/ha glyphosatr (41% SL) plus 8 kg/ha ammonium sulphate for 2 times, spraying with 6 L/ha glyphosatr (41% SL) plus 8 kg/ha ammonium sulphate for 1 time, for 4 years. Cutting of swallowort two times + spraying with 6 L/ha glyphosatr (41% SL) plus 8 kg/ha ammonium sulphate for 1 time, spraying with 2 L/ha Triclopyr (62% EC) for 3 times, spraying with 2 L/ha Triclopyr (62% EC) for 2 times, spraying with paraquqt 2 times, cutting of swallowort 2 times+ spraying with 2 L/ha Triclopyr (62% EC) for 1 time, spraying with paraquqt (20% SL) 2 times+ spraying with 2 L/ha Triclopyr (62% EC) for 1 time, spraying with paraquqt (20% SL) 2 times+ spraying with 6 L/ha glyphosatr (41% SL) plus 8 kg/ha ammonium sulphate for 1 time, spraying with 2 L/ha Triclopyr (62% EC) for 1 time+ spraying with 6 L/ha glyphosate (41% SL) plus 8 kg/ha ammonium sulphate for 1 time, and control without weed spraying. Results shoewed that the best treatment for the control of swallowort was Rounup 6L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha, 3 times spraying with paraquat and 2 times spraying with paraquat. Results of the second year shoewed that the best treatment for the control of swallowort was Triclopyr 2L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha. Results if the third year shoewed that the best treatment for the control of swallowort was Rounup 6 L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha. Results of the first year in Yazd shoewed that the best treatment for the control of swallowort was Rounup 6L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha, 3 times spraying with paraquat and 2 times spraying with paraquat. Results of second year in Yazd shoewed that the best treatment for the control of swallowort was Rounup 6L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha, 3 times spraying with paraquat and 2 times spraying with paraquat. Results of third year in Yazd shoewed that the best treatment for the control of swallowort was Rounup 6L/ha, and the weakest treatment was 2 times spraying with Rounup 2 L/ha, 3 times spraying with paraquat and 2 times spraying with paraquat.
