Testing of New Brand Formulations of Sulfonylurea Herbicides for Control of Mixed Weed Flora in Wheat

Abstract

A field experiment was conducted during rabi 2013–14 to test two new brands of sufonyl urea herbicides from Markfed-Mark sulfo @ 0.024 kg a.i/ha (new brand of sulfosulfuron) and Markpower @ 0.03 kg a.i./ha (new brand of sulfosulfuron+metsulfuron) in wheat. Standard check herbicide Leader @ 0.024 kg a.i/ha (sulfosulfuron) against Mark sulfo was tested and recorded weed control and grain yield at par in both the treatments. Similarly, Markpower @ 0.03 kg a.i./ha (new brand of sulfosulfuron+metsulfuron) was tested against Total @ 0.03 kg a.i./ha (standard check) in wheat which resulted in weed control and grain yield at par with check herbicide.
