Tank mix effect of 2,4-D + MCPA and Glyphosate herbicides in integrated control of Mesquite(Prosopis farcta)

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〣 at 2 and 4 Lit.ha-1 one time and 2,4-D〣 at 1 and 2 Lit.ha-1 two times. Integrated treatments include 2,4-D〣 plus Glyphosate at 1 and 2 Lit.ha-1 two times; 2,4-D〣 plus Glyphosate at 2 and 4 Lit.ha-1 one time; cutting one time; cutting 2,4-D〣 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〣) 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〣 (2 lit.ha-1) Glyphosate (4 lit.ha-1), with 97.78% ; 2,4-D〣 (1 lit.ha-1) Glyphosate (2 lit.ha-1) with 97.22% and 2,4-D〣 (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〣 at 2 lit.ha-1 two times; 2,4-D〣 4 Lit.ha-1 and 2,4-D〣 1 Lit.ha-1 two times with 1.09, 2.12, 4.37 and 4.57 gr. respectively.
