Abstract

In order to evaluation the efficacy of indaziflam on control of purple nutsedge in sugarcane an experiment was conducted in 2015 growing season in a sugarcane field in Shoaeibiyeh, Shoushtar, Khouzestan, Iran. Trial was randomized complete block design with four replications. Treatments were 1-indaziflam (75 g ai ha-1, as preemergence); 2-indaziflam (50 g ai ha-1 as preemergence); 3-Trifloxysulfuron sodium+ametryn; 2, 4-D+MCPA (1687. 5 g ai ha-1); 5-2, 4-D+MCPA+metribuzin (1350 g ai ha-1+1400 g ai ha-1); 6-weeding and 7-weed infested. The results showed indaziflam as 75 g ai ha-1 affected purpule nutsedge growth as dry weight and density reduction percentage of purple nutsedge was reduced 100% until 30 day after treatment (DAT). However, indaziflam efficacy was reduced over time. Other herbicides such as indaziflam as 50 g ai ha-1 and trifloxysulfuron sodium+ametryn indicated good effect in purple nutsedge control compared with 4-2, 4-D+MCPA and 2, 4-D+MCPA+metribuzin. Single stem weight (0. 70 kg m-2), the middle internode diameter (1. 83 cm), number of internode (18. 3 cm) and cane yield (117. 88 t ha-1), were the greatest in indaziflam (75 g ai ha-1). The greatest Brix (21. 40%), invert sugar (25. 53%), recoverable sugar (11. 0%) and the lowest fiber content (12. 60 t ha-1) were obtained in indaziflam (75 g ai ha-1).
