In order to investigatsion of integrated management of mesquite, an experiment was conducted with 16 treatments in randomized compelete blocks design with 3 replications at Yazd province during 2010-2014. Treatments included: Glyphosate at 6, 8 and 10 Lit.ha-1 one time and Glyphosate at 3, 4 and 5 Lit.ha-1 two times; 2,4-D+MCPA at 2 and 4 Lit.ha-1 one time and 2,4-D+MCPA at 1 and 2 Lit.ha-1 two times. Integrated treatments include 2,4-D+MCPA plus Glyphosate at 1 and 2 Lit.ha-1 two times; 2,4-D+MCPA plus Glyphosate at 2 and 4 Lit.ha-1 one time; cutting one time; cutting+ 2,4-D+MCPA at 2 Lit.ha -1 ; cutting+ Glyphosate at 4 Lit.ha-1 and Control with no treaetment. Results of the 3 years experiments showed that the treatments of cutting, cutting+ (2,4-D+MCPA) at 2 lit.ha-1 and cutting + Glyphosate 4 lit.ha-1 decreased the dry weight of mesquite in acceptable quantity. The highest percent control of mesquite was observed in 2,4-D+MCPA (2 lit.ha-1) + Glyphosate (4 lit.ha-1), with 97.78% ; 2,4-D+MCPA (1 lit.ha-1) + Glyphosate (2 lit.ha-1) with 97.22% and 2,4-D+MCPA (4 lit.ha-1) with 85.00 %. Based on the results of 3 years of the experiment the lowest of dry weight observed in cutting treatment and 2,4-D+MCPA at 2 lit.ha-1 two times; 2,4-D+MCPA 4 Lit.ha-1 and 2,4-D+MCPA 1 Lit.ha-1 two times with 1.09, 2.12, 4.37 and 4.57 gr. respectively.
