A field experiment was conducted during 2015-16 and 2016-17 at Rajasthan
College of Agriculture, Udaipur, India with the objective to assess bio-efficacy
potential of the ready-mix herbicides against complex weed flora in wheat. The
experiment consisting of fifteen treatments, was laid out in a randomized block
design with four replications. The results indicated significant reduction in
population and growth of weeds by ready-mix application of sulfosulfuron +
metsulfuron (32.0 g/ha) and mesosulfuron + iodosulfuron (14.4 g/ha) followed
by clodinafop + metsulfuron (64.0 g/ha), pinoxaden + metsulfuron (64.0 g/ha)
over other weed control treatments. However, two hand weeding (30 and 45
DAS) registered maximum decline in density and dry biomass of all the weeds.
Moreover, herbicides combination sulfosulfuron + metsulfuron and
mesosulfuron + iodosulfuron attributed to greater value of weed control index
(WCI) with maximum reduction of weed density and dry biomass. At 60 DAS,
the array of WCI ranged from 9.19 to 95.01 and 57.48 to 97.01% for monocots and
dicots, respectively and resulted into higher grain yield (34.3 and 20.5% more),
net returns (49.1 and 47.7% more) and B-C ratio (2.34 and 2.32) over the
unweeded control. The study concluded that the use of sulfosulfuron +
metsulfuron (32.0 g/ha) and mesosulfuron + iodosulfuron (14.4 g/ha) as postemergence at 5 WAS provided efficacious control of all sorts of weeds in wheat
with higher yield and net returns.
