Delta Farm Press
by Jarrod Hardke, Rice Extension Agronomist - April 29, 2022
“I been wastin’ my time, don’t need no more rain, I been gone for so long, I think
the devil lost my name.”
Weather finally turned in our favor starting mid-week and planting progress actually
occurred statewide for the first time all year. While it’s only a few days, some
were able to make huge leaps in planted acreage in that time. Most will continue
to press their luck on Saturday and hope scattered rains miss them to allow for additional
planting on Sunday.
That’s the first good news to report in a while. Then more rain chances are forecast
for the majority of next week, and that’s more bad news. Another lost week of planting
spells bad things for total rice acres in the state. The game is far from over, and
the price situation will encourage continued acres, but only time will tell how this
Rice that has already emerged isn’t always looking that great right now. Several
straight years of cool, wet springs are making this the norm. The upside of current
and upcoming weather is warmer temperatures that will hopefully help straighten up
the early rice.
With everyone trying to get something planted this week, plenty for the first time,
it’s a wild guess as to just how much overall progress is being made. As of 4/25
we were 14% planted, and even if we jump to 30% planted we’ll still be behind 2019
and 2020. Anything less than 33% on Monday’s report and we’ll still be on the slowest
pace since 1993 (15%).
New on Arkansas Row Crops Radio this week:
Rice & Advice Series, S2 Ep 2: Importance of Nitrogen Source Selection for Rice
There definitely seems to be some confusion over naming conventions right now and
what is what when it comes to rice. Let’s do a quick review to be sure we all know
what we’re working with this season and prevent any headaches.
Conventional varieties – Diamond, Jewel, Titan, Jupiter, Lynx, DG263L
These varieties have NO herbicide tolerance traits. The public varieties have seeding
rates recommended in the range of 70-90 lb/acre. DG263L is different and can be planted
at these rates but may be seeded at 45-60 lb/acre.
Clearfield varieties – CLL15, CLL16, CLL17, CLM04, CL111, CL151, CL153, CL163.
The older varieties are more well-known (CL111, CL151, CL153, CL163) where CL stands
for Clearfield and then the number of the release. The newer varieties (CLL15, CLL16,
CLL17, CLM04) have CL for Clearfield to start, then an L or M to designate Long-Grain
or Medium-Grain, then the release number. These varieties have seeding rates recommended
in the range of 70-90 lb/acre.
Provisia varieties – PVL02, PVL03
Provisia has a PV to start then an L for Long-Grain, then the release number. Tolerant
only to Provisia herbicide. Also note there no medium-grain cultivars tolerant to
Provisia at this time. These varieties have seeding rates recommended in the range
of 70-90 lb/acre.
Conventional hybrids – RT XP753, RT 7301, RT 7401, RT 7501
These hybrids have NO herbicide tolerance traits. These hybrids have seeding rates
recommended in the range of 22-27 lb/acre.
FullPage hybrids – RT 7321 FP, RT 7521 FP, RT 7421 FP
These hybrids begin with a 7 to designate long-grain, the second number indicates
maturity, the third number is herbicide tolerance (2=FullPage), and the fourth number
is the release number. The FP at the end is added confirmation that they’re FullPage.
Tolerant only to Preface and PostScript herbicides. These hybrids have seeding rates
recommended in the range of 22-27 lb/acre.
MaxAce varieties – RTv7231 MA
Similar to the previously mentioned RT naming convention, but notice the “v” in there
to specify that it is a VARIETY, NOT a hybrid. The third number is herbicide tolerance
(3=MaxAce), and the fourth number is the release number. The MA at the end is added
confirmation that it’s MaxAce. Tolerant only to Highcard herbicide. This variety
has a recommended seeding rate of 45 lb/acre.
MaxAce hybrids – RT 7331 MA
Similar to the previously mentioned RT naming convention. This is a hybrid. The
third number is a 3 meaning MaxAce, and MA at the end is added confirmation. Tolerant
only to Highcard herbicide. This hybrid has a recommended seeding rate of 22-27 lb/acre.
With our rice planting still on-going, we wanted to remind everyone about the importance
of following the herbicide label and rice seed agreements regarding Provisia and Max-Ace
Both Provisia and Max-Ace are quizalofop-resistant cultivars, but they require a specific
tradename herbicide to be applied legally and safely. In Provisia rice, Provisia
herbicide is labeled for use. In Max-Ace rice, Highcard herbicide is labeled for use.
They cannot be mixed and matched (i.e., Provisia herbicide CANNOT be sprayed on Max-Ace
rice and Highcard CANNOT be sprayed on Provisia rice).
Outside of labeling laws, it is also important to abide by these rules due to rice
sensitivity to the herbicide active ingredient quizalofop. Highcard herbicide has
a safener to help safen Max-Ace rice (regardless of if it’s the variety or hybrid)
from injury, whereas Provisia herbicide contains no safener. Provisia sprayed on
Max-Ace rice, especially in cool and wet conditions, can lead to substantial injury.
This was recently observed in a field by Dr. Connor Webster, Rice Extension Weed
Specialist at Louisiana State University, which you can see in his tweet below. For
more details on this specific case, check out our Weeds AR Wild podcast episode this
week in which Dr. Webster joined us to discuss this topic along with other rice weed
control advice from Louisiana:
Weeds AR Wild Series, S2 Ep 11: Rice Weed Control Advice from Louisiana
It is important to note this distinction as we have been told there is a potential
shortage of Highcard herbicide for 2022 (as is the case with many herbicides this
year). If you are or were planning on planting Max-Ace rice, make sure you also have
access to or have in-hand the Highcard herbicide that goes with it. Otherwise, you
will be unable to take advantage of the technology. For those planting Provisia rice,
there is no reported shortage of Provisia herbicide, so you should be in the clear.
For both systems, it is recommended to apply the quizalofop (Provisia or Highcard)
herbicide at 15 fl oz/acre sequentially. The first application should occur at roughly
2-3 leaf rice with the second application occurring at 5-6 leaf rice (preflood). If
broadleaf or sedge herbicides are also required, it is recommended to mix those herbicides
with the Provisia/Highcard in the first application. More information on herbicide
mixtures and antagonism with Provisia/Highcard herbicides was also discussed in the
previously mentioned podcast with Dr. Connor Webster, so make sure to check it out!
Finally, as a reminder, a strong, overlapping residual herbicide program is also
still key for successful, long-term weed management and delaying the evolution of
As always, if you have any questions, please don’t hesitate to get ahold of us, and
good luck out there!
Rice futures put in another good week with new highs in the September contract. Trading
Thursday touched $17.29 with a close at $17.24. This is the highest trading for the
September contract since 2011. New crop bids at east Arkansas mills on Thursday were
$7.62 to $7.67/bu. for fall delivery. Bids for first quarter 2023 delivery were $7.76/bu.
CBOT September Rice Futures, 15-Year Monthly Continuation.
The rice market is largely focused on Midsouth weather and what it could mean for
2022 production. There’s also some spillover support from the major grains and soybeans.
The war in Ukraine continues to generate uncertainty, particularly for corn and wheat.
The slow start to planting in the Cornbelt has also kept markets nervous. Brazil
has had its driest April in 17 years.
Recall in USDA’s March planting intentions, Arkansas was expected to plant 1.19 million
acres of rice in 2022—down 2 percent from last year. Mississippi and Missouri rice
acreage was projected to be down 5 percent. Given the historically slow planting
pace in the Midsouth, the rice market senses the possibility of a further reduction
in acres. As the calendar flips to May, the potential to shift acres to $15 soybeans
As odd as it may sound, this could be a year to stick with your original plans. The
current supply-chain challenges are reason enough. If you have all your seed, fertilizer,
and chemicals for the growing season, that alone is priceless. Significantly altering
your planting intentions could create a new set of challenges in securing inputs.
In addition, the current price strength and the market outlook for rice is encouraging.
If rice planting extends into late May, look for the September contract to retest
the 2011 highs near $18.25. For Arkansas, the crop insurance final planting date
for rice is May 25th. Prevented planting will no doubt be a consideration in a year with historically
high insurance guarantees. Unfortunately, there appears to be little chance for field
work next week.
In this week’s USDA Crop Progress report, 26 percent of intended U.S. rice acreage was planted as of April 24th. This lags the 45 percent planted last year and the 5-year average of 47 percent.
Note the planting progress for the Midsouth states compared to the 5-year average.
This year is the slowest start for Arkansas since 1993. Based on historical averages,
Arkansas, Mississippi, and Missouri would normally be 50 percent (or more) planted
by May 1.

This was a volatile week for New Orleans urea prices with barges trading in a $100/ton
range. Barges traded down to $620/ton early in the week before recovering to $720/ton
Thursday. Wet weather and lower corn acreage estimates have provided a softer tone
to the urea market for most of April. The late week recovery in urea came from a
1.5-million-ton tender from India. The recent weakness we’ve seen in retail urea
prices may be coming to an end. Expect firmer prices to start the new month.
