Effect of different herbicides on Cyperus rotundus L. in turf

Author(s): Maitri Desai, GD Patel, NK Patel, ST Bhatt and Manoli Patel
Abstract:
An experiment was conducted during 2016-17 at Regional Horticultural Research Station, ACHF, NAU, Navsari, Gujarat to study the effective method to control Cyperus rotundus L. with appropriate concentration. The experiment was laid out in Randomized Block Design with ten treatments viz. Halosulfuron Methyl 75% WG @ 2.4 and 3.3 g/10 l foliar spray, Ammonium Salt of Glyphosate 71% SG @ 75 and 100 g/10 l foliar spray, Glyphosate 41% SL @ 110 and 150 ml/10 l foliar spray, 2,4-D Ammonium Salt @ 30 and 40 g/10 l foliar spray, Manual Management and Control with three replications. The results on growth attributes of lawn viz. leaf width, leaf length and chlorophyll content of lawn were found maximum with Manual Management which was statistically at par with Halosulfuron Methyl 75% WG @ 2.4 g/10 and Halosulfuron Methyl 75% WG @ 3.3 g/10 l. As per the ranking of aesthetic value of lawn, Manual Management and Halosulfuron Methyl 75% WG @2.4 and 3.3 g/10 l found more effective while, the lowest ranking was recorded in Glyphosate 41% SL @ 150 ml/10 l foliar spray. On the basis of visual phytotoxicity symptoms, Manual Management and Halosulfuron Methyl 75% WG @2.4 and 3.3 g/10 l was not observed with any phytotoxicity whereas, highest phytotoxicity and least visual ranking was observed in plot treated with Glyphosate 41% SL @ 150 ml/10 l foliar spray. Maximum weed control efficiency was found in Halosulfuron Methyl 75% WG @ 3.3 g/10 l foliar spray and chlorophyll of Cyperus rotundus L., all herbicides were effective to reduce the chlorophyll content.
