“Burn out the day, burn out the night…”
It’s been quite the warm week in Arkansas as was forecast. Luckily, it looks as though
we’re expected to get that all-important “around the 4th of July” rain. We missed on it last year, but this year we appear to be on a much
smoother track so far.
We’re transitioning now into the mid- to late-season issues. That’s not to say we
have a lot of issues currently, just that the conversations are shifting. We covered
the importance of identifying diseases last week, and sure enough this week has had
more questions about “is this brown spot, is this blast, etc.” A number of the fields
are brown spot – which means its perhaps time to do some tissue testing and ensure
our potassium levels are adequate (please don’t spray a fungicide for brown spot).
But some others have been blast in northeast Arkansas. Conditions are slightly conducive
for blast right now because it’s so hot making it difficult to maintain adequate flood
depth. Next week, it could get worse as temperatures slack off with rains expected
with some cloudy weather. Only time will tell. Rarely do we need to spray a fungicide
for leaf blast – we usually need to save that money for preventing neck blast.
Sheath blight calls have been few, but I know there have been applications going out
for it. Remember, if it’s staying low in the canopy and not moving up and threatening
upper leaves, take a wait and see approach. Let’s try to outrun it for as long as
we can. But next week, like already mentioned, things could get fired up, so be diligent
Let us know if we can help.

The 2023 Rice College will be held Aug. 16, 2023, from 9 a.m. to 4 p.m. (tentatively)
at the University of Arkansas System Division of Agriculture’s Rice Research and Extension
Center near Stuttgart. The station address is 2900 Hwy. 130 E., Stuttgart, AR 72160.
Crop consultants, industry personnel, and producers will see current research on many
of the production challenges Arkansas rice producers are experiencing today. Attendees
will participate in field presentations from UA Division of Agriculture personnel
and have the opportunity to take part in hands-on (boots on!) demonstrations. CEUs
will be available and lunch will be provided.
The program is still being finalized but plans include agronomy, fertility, weed science,
entomology, irrigation, and pathology tours.
Cost of attendance is $100 and you must register by Aug. 10 at the following link: https://uada.formstack.com/forms/2023_rice_college
The severe winds on Sunday, 6/25, left many without power for a few days and definitely
gave folks a good scare. Rice held up very well, with most of the crop being just
young enough to be flexible and handle the storms. Leaf tip injury is the most common
symptom, most all of which is minor. We didn’t need this to happen to heading rice,
that’s for sure.
Ultimately the rice will be fine and go back to growing right along, but the rice
may have an odd shade to it until new leaves overshadow the ones with injured tips.
Be mindful that there can be other issues in the field and these symptoms can cause
confusion when diagnosing other problems.

The tables below include USDA’s planted acreage estimates for rice from the June 30
Acreage report. The survey for the Acreage report is conducted during the first two weeks of June. The findings indicated a
104,000-acre increase in total U.S. rice since the March Prospective Plantings survey. At 2.687 million, total U.S. rice acres would be the highest since 2020.
Table 1. 2023 U.S. Planted Acres, Rice.
Since the March 31 intentions report, Arkansas’ rice acres were revised 10,000 acres
higher with an increase in long-grain acres. Total acres have returned to a healthy
1.311 million acres. The only surprise here is that more acres weren’t added to the
report. Based on the early and continued planting this spring, acres appeared to
climb further beyond March expectations.
Table 2. 2023 Arkansas Planted Acres, Rice.
The table below provides a look at state totals for long-grain rice acres. In the
June Acreage, USDA made upward adjustments for Arkansas, California, Louisiana, and Texas with
no changes for Mississippi and Missouri.

I certainly have no crystal ball on the direction of the market from here. But it
is interesting to note the 100-day and 20-day moving averages closing in on each other.

The DD50 Rice Management Program is live and ready for fields to be enrolled for the
2023 season. All log-in and producer information has been retained from the 2022
season, so if you used the program last year you can log in just as you did last year.
Log in and enroll fields here: https://dd50.uada.edu.
The Arkansas Rice Advisor site https://riceadvisor.uada.edu functions like an app on your mobile device. There you can readily access the DD50
program, rice seeding rate calculator, drill calibration, fertilizer and N rate calculators,
publications, and more.
Arkansas Rice Updates are published periodically to provide timely information and
recommendations for rice production in Arkansas. If you would like to be added to
this email list, please send your request to firstname.lastname@example.org.
This information will also be posted to the Arkansas Row Crops blog (http://www.arkansas-crops.com/) where additional information from Extension specialists can be found.
More information on rice production, including access to all publications and reports,
can be found at http://www.uaex.uada.edu/rice.
We sincerely appreciate the support for this publication provided by the rice farmers
of Arkansas and administered by the Arkansas Rice Research and Promotion Board.
The authors greatly appreciate the feedback and contributions of all growers, county
agents, consultants, and rice industry stakeholders.
