Abstract

A study was conducted at Rice Research Station Bahawalnagar during Kharif, 2015 and Kharif, 2016 for weed control in rice variety (PS-2) cultivated under transplanted method. To manage the weeds in transplanted rice five weedicides were tested. Out of five weedicides viz. Machete (Butachlor), Clover (Bispyrabic sodium), Winsta (Bispyrabic sodium+Bensulfuronmethyl), Machete+Clover (Butachlor+Bispyrabic sodium), Machete+Winsta (Butachlor+Bispyrabic sodium+Bensulfuronmethyl) applied, gave maximum paddy yield of 3.4 t/ha with least weeds intensity in 2015 and 3.5 t/ha with least weeds intensity in 2016. Weeds intensity reduction due to weedicides application ranged between 67.74 to 93.54 percent in 2015 and ranged 63.33 to 90 percent in 2016.
