LITTLE ROCK — A team led by Tommy Butts, extension weed scientist for the University
of Arkansas System Division of Agriculture, will be exploring new ways to manage herbicide-resistant
weeds in row rice and traditional flooded field production, thanks to a $324,000 grant.
The grant is part of a $4.6 million investment by the National Institute of Food and
Agriculture, or NIFA, part of the U.S. Department of Agriculture, toward the development
of innovative pest management strategies.
Working with Butts on the project are Jason Norsworthy, Division of Agriculture weed
scientist; Jason Bond, research and extension weed scientist at Mississippi State;
Jarrod Hardke, extension rice agronomist for the Division of Agriculture; Tom Barber,
extension weed scientist for the Division of Agriculture and Bobby Golden, extension
rice and soil fertility agronomist for Mississippi State.
The research is needed as Arkansas rice producers increasingly move from traditional
flood production to row rice, also known as furrow irrigated rice, or FIR, production.
Arkansas had 40,000 acres of row rice in 2017. That number jumped to more than 100,000
acres in 2018 and may be more than 200,000 acres in 2020.
The team will focus on herbicide-resistant barnyardgrass and Palmer amaranth, or pigweed,
which has been a bane to cotton and soybean growers across the Mid-South.
Butts said that when talking to rice growers, “barnyardgrass is our No. 1 rice weed
In conventional production, flooding tamps down pigweed and other weeds. However,
row rice is grown without a flood, leaving it open to the same pests as other row
“When we asked growers about row rice, Palmer amaranth is pretty much right there
as No. 1 or No. 2,” Butts said.
The research will look at the effect changes in cultural practices such as spacing
between plants and the type of nozzles – single-fan and double-fan – used to deliver
herbicides will have on production.
Butts said research being done by Hardke has shown that “drill spacings wider than
the standard 7.5-ich spacing could perform competitively. However, wider spacing also
results in more space for weeds to grow.”
The research also brings “in some of my application technology background,” Butts
said. “We will be looking at several nozzle types to see how different drill spacing
would affect our spray coverage and overall weed control. For example, with different
spacing, how much rice might block herbicide from hitting target weeds?”
The research will be conducted on three sites in eastern Arkansas. The Mississippi
researchers will have corresponding plots at Stoneville, Mississippi.
Arkansas is the nation’s top rice producer, with more than 1.4 million acres planted
in rice in 2020. In 2019, Arkansas’ rice crop was valued at more than $980 million.
Hardke said that the research is necessary: “If furrow-irrigated rice is to have continued
prolonged success, best management practices need to be developed quickly for growers
to achieve the maximum benefit from this practice.”
The NIFA grant number for this project is 2020-70006-32981.
