Survey Shows Majority Of Growers Face Glyphosate-Resistant Weed
Three out of four
growers who participated in a recent survey by BASF suspect that glyphosate
resistance is a cause of their tough-to-control weeds. As a result, a
staggering 76 percent of these growers have already changed their weed
management program to address resistance.
In addition, many growers have experienced lower yields,
which they attribute to resistant weeds. These growers have also spent more
time scouting and invested more money in their crops due to resistant weeds.
In the survey, growers identified how they plan to change
their programs in 2014. More than two-thirds of growers indicated that they
would be applying a pre-emergence herbicide this season and more than half of
growers are planning to add an additional herbicide to their existing program.
Additionally, 50 percent of growers plan to use more than one site of action
and 47 percent said they plan on using overlapping residual herbicides to
control resistant weeds.
“These results show that growers are beginning to understand
the need for a comprehensive weed management approach,” said Greg Armel, Ph.D.,
Technical Market Manager, BASF. “Growers are realizing the importance of using
residual herbicides and multiple, overlapping herbicide sites of action.”
The survey also highlighted the weeds that growers found the
toughest to control in 2013. Nearly two-thirds of respondents said waterhemp
was the most difficult to control, while 54 percent said that ragweed species
were the toughest to control. Lambsquater and marestail were also identified as
