Management of Cyperus rotundus L. in Turf


Author(s): Maitri Desai, GD Patel, NK Patel and Vaishali 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 (mm), leaf length (cm), number of runners per 100 cm2 area, number of leaf on runner were found maximum with Manual Management which was statistically at par with Halosulfuron Methyl 75% WG @ 3.3 g/10 l and Halosulfuron Methyl 75% WG @ 2.4 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. Highest population density of Cyperus, weed control efficiency and minimum weed biomass was found in Halosulfuron Methyl 75% WG @ 3.3 g/10 l foliar spray.
