Topramezone 10g/l + atrazine 300 g/l sc an herbicide for controlling narrow and broad-leaved weeds in sugarcane

Abstract

To control narrow and broad-leaved weeds in sugarcane, bio efficacy of Topramezone 10g/l + Atrazine 300 g/l SC in different doses along with other herbicides were tested in field conditions during 2016-17. In this experiment, all the treatments of herbicide found to be significant in reducing the weed count and increasing the cane yield in comparison to untreated control. In all the treatments, Topramezone 10g/l + Atrazine 300 g/l SC @ 3500 ml or 1085 g a.i. per ha was found to be superior in controlling all kind of weeds in the sugarcane. The weed control efficiency of above treatment was 72.65, 80.80, 69.11, 90.71, 92.3, 85.17, 83.51 and 77.58 percent for Echinochloa colonum, Cynadon dactylon, Panicum fasiculatum, Parthenium spp, Amaranthus viridis, Euphorbia spp, Commellina benghalensis and Altrenentra sessalis, respectively. Topramezone 10g/l + Atrazine 300 g/l SC @ 3500 ml or 1085 g a.i./ha was also responded with maximum yield as recorded 107.03 t/ha against 76.53 t/ha in untreated control.
