Effective Crop Rotation – Rice

Where glyphoasate resistant pigweed had become
difficult to control in soybeans, rice can be an excellent rotation crop to
help break the pigweed cycle. Unfortunately, in rice most fields have levees
for irrigation, these are above the flood water and pigweed
can thrive on these levees. “2,4-D” is one of the best options that
we have for pigweed control on rice levees. Unfortunately “2, 4-D” has been banned
after April 15th in many counties in Arkansas. For those growers who can’t use “2, 4-D”
to control pigweed on levee the University recommends starting off with
a residual program just prior to flood, such as Prowl or Bolero applied to the levees
just prior to pigweed emergence. After pigweeds have emerged on levees
if you can’t use “2, 4-D” products like Aim and propanil
or Grandstand plus propanil can be effective in pigweed suppression.
Especially in the areas where we have a ban on “2, 4-D”
or we have crops that are sensitive to “2, 4-D” in close proximity,
pigweed control on the levees can be much more difficult
than in other areas. We have a section in the MP44 dedicated to
levee weed control. You can find the Mp44 at your local county
office or on the web at www.uaex.edu. Your Arkansas soybean podcast is a production
