EFFICACY OF DIFFERENT WEEDICIDES TO CONTROL WEEDS IN SUGARCANE

Abstract

A field study to determine the relative efficiency of cultural and chemical weed control in spring planted sugarcane was conducted at Sugarcane Research Station, Khanpur during 2007. Four weedicides namely Krismat 75 W.G, Prexmixtra gold 720 S.C, Authority 4 F, Atrazine+Ametryne 80WP and hand weeding were tested against weedy check. The results revealed that both control measures gave better weed control as compared to weedy check. Hand weeding excelled with 85.13 percent weed control comparably followed by Krismat and Atrazine+Ametryne. An increase in cane yield ranging from 4.02 to 33.43 percent was observed. Hand weeding, Krismat application and Atrazine+Ametryne spray gave matching maximum cane yields of 111.03, 110.63 and 102.88 tons per hectare, respectively.
