“It’s been such a long time, I think I should be going.”
So close, and yet so far away. Very little progress to speak of yet again this week
after more rainfall events. As usual, amounts were variable depending on where you
were, but everyone received a share. By Thursday a few lucky spots were able to return
to the field, but most are just now drying up into the weekend with a very wet upcoming
forecast starting Monday. I even saw a drill running in some spitting rain today.
This past Monday we were only reported to be 2% planted so far, and it’s unlikely
that the upcoming report will reach even 5% planted. Over the past 5 years, we would
be 20-25% planted by this point in the year. Considering some of the recent years
that are included in that average, you could argue that we’re overall way behind.
Sorry, I hope you didn’t start reading this expecting a lot of good news since I haven’t
given any. One bright point to spotlight is that even though in recent years we’ve
tended to plant rice later than we want, our yields have clearly been doing very well.
So ultimately let’s hope that the weather is once again pushing us into an optimum
window for making solid yields whether we know it yet or not.
If you are in need of a laugh, saw this one today:
This week, the EPA announced that anthraquinone, the active ingredient in AV-1011
used as a seed treatment bird repellent in rice, is under registration review. As
part of this review, it was found that detectable levels of anthraquinone may be present
in harvested rice grain. There is currently no tolerance limit set for anthraquinone
in harvested rice grain, so additional data is needed from the registrant to fill
this data gap. This data is not expected to be available until 2024 at the earliest.
In the immediate, there is not a defined impact to rice growers using AV-1011 in rice
– “… EPA has concluded there are no resulting risks of concern from the consumption
of rice commodities that could enter or are already available from the channels of
trade.” Because EPA does not consider dietary exposure to anthraquinone a safety
concern, FDA does not intend to start routine testing on rice from this year’s harvest
or past harvests. However, FDA is planning to incorporate anthraquinone as an analyte
in the quantitative multi-residue method used by the Pesticide Residue Monitoring
Program in the future once EPA’s registration review process is complete (~2024) and
may take regulatory action if violative anthraquinone residues are found. For general
information about how FDA enforces pesticide tolerances, visit the FDA Center for
Food Safety and Applied Nutrition (CFSAN) pesticides webpage.
At this time, it is my understanding that there is not an issue with the use of AV-1011
(anthraquinone) in rice for 2022. However, this could change in upcoming seasons
once the EPA’s registration review process is complete.
The complete statement is available here: https://www.epa.gov/pesticides/epa-takes-next-step-review-anthraquinone. EPA plans to issue a Data Call-In (DCI) this month for the data needed to establish
a tolerance, and welcomes comments on the draft risk assessments for anthraquinone
over the next 60 days (https://www.regulations.gov/docket/EPA-HQ-OPP-2017-0326).

Acres continue to shuffle from one commodity to another at a rapid rate, and upcoming
additional rainfall will likely continue that trend. With that going on, we’re already
hearing of numerous potential mistakes related to plant-back intervals.
First off, remember that for our burndown herbicides, some can cause us problems in
rice if we don’t adhere to the plant-back interval. Some notable intervals are included
in Table 1. This information is also available in the 2022 Rice Management Guide.
Table 1. Notable burn-down herbicides with plant-back intervals to rice.
Plant-Back Interval for Rice
Valor / Afforia
Zidua SC (3.25 oz)
1 Plant-back days are rate dependent, days presented are for lowest labeled rate.
Aside from just rice and burndown herbicides, remember some of the more restrictive
plant-back intervals for herbicides we use in-crop that limit our rotational options
the following year. One example would be planting corn behind Clearfield or FullPage
rice – for Newpath/Preface use rates greater than 8 oz/A per season, only soybeans
may be planted the following year. There are other examples, that’s just one that’s
come up recently. Additional information on most common herbicides is available in
the MP519 Row Crop Plant-Back Intervals for Common Herbicides.
USDA’s April WASDE provided a couple changes to the old crop long-grain balance sheet.
Domestic Use was increased 2 million cwt. to 115 million. This reduced ending stocks
by the same amount to a net 19.4 million cwt. This will be the Beginning Stocks for
the new crop (2022/23) balance sheet USDA will release May 12th. Today’s old crop
adjustments only support the outlook for price volatility in the year ahead.
One other note in the long-grain balance sheet, USDA lowered the 2021 season average
price 20 cents per hundredweight to $13.80. Assuming this price outlook holds, this
would generate a small PLC payment of 9 cents per bushel. USDA will announce the
final 2021 PLC payment rate in October.

Of interest in the World rice balance sheet, USDA lowered Brazil’s production this
month to 7.14 mmt, compared to 8 mmt last year. Also, Brazil’s rice exports were
lowered to 780,000 tons. This would be Brazil’s lowest production since 2018 and
lowest exports since 2015.
Following today’s USDA report, old crop rice futures are trading about a dime lower,
while new crop is 8 to 16 higher. The September ’22 contract has been finding overhead
resistance at $16.08/cwt. Fairly consistent support has been at $16 over the past
week. As of Friday morning, new crop bids at mills around eastern Arkansas were $7.10/bu.
for August to October delivery.
USDA’s first Crop Progress report of the year indicated 12 percent of the U.S. rice
crop was planted as of April 3rd; slightly behind the average pace for this time of
year. Most of the planting has been in Louisiana and Texas so far. Arkansas and
Mississippi’s planting progress was estimated at 2 and 3 percent respectively. Little
in the way of progress has been made in the Midsouth this week. More rain chances
are in the outlook for the early part of next week.

The graph below provides a look at New Orleans barge prices for DAP, Urea and Potash
over the past year. Prices for all three nutrients made new highs following the February
24th Russian invasion of Ukraine. This week urea and phosphate prices backed off
some at New Orleans (NOLA) as wet weather delays planting. Fertilizer prices were
also weaker in response to USDA’s projected drop in 2022 corn acreage.
At mid-week, New Orleans (NOLA) urea traded in the $780 to $800 per ton range, down
sharply from last week’s $880 to $940 range. NOLA phosphates were also down, trading
at or below the prior week’s low of $960 per ton. Potash remained firm at NOLA this
