OVERVIEW

Rice is heading in southwest Louisiana on a very limited basis in February-planted fields. More rice is at PD in Texas and Louisiana.

 

Disease is becoming a bit more apparent in south Louisiana. See comments by Dustin Harrell.

 

Fields are moving to flood on a wider basis in the Midsouth. Rains over the last week have delayed progress in places and also kept fields too wet in the upper Delta to consider applying fertilizer right away.

 

Delays in Arkansas have kept at least some growers from taking fields to flood, especially in areas that were hit hard in early May by excessive rainfall and river flooding. Growers either didn’t have levees up before the flooding or lost levees to the rising waters. Enough rain has fallen since then to prevent levee building over the last couple of weeks. This has put farmers behind the 8 ball where they need to apply pre-flood nitrogen and pump up the ground. See comments by Jarrod Hardke.

CROP REPORTS

Gus Lorenz, Arkansas Extension IPM Specialist

“Some of the earliest rice has been at flood for 21 days, which is near the point that we start sampling for rice water weevils (RWW). Remember that RWW females are attracted to rice once the flood is established, and they’ll move out of tree lines to begin laying eggs.

 

“At two or three days after flooding start looking for signs of RWW, especially if you didn’t use a seed treatment or it’s been over 30 days since planting. Chances are, the seed treatment has played out, especially if it’s a neonic material. Check for leaf scarring. If you’re running 30% to 40% scarring on new leaves, a foliar insecticide would be advisable.

 

“To some extent, RWW trends have been more complicated in recent years because people are planting rice earlier and earlier, so fields might be caught by poor growing conditions that delay flooding. Plants will stall out long enough to lose any control from seed treatments. And seed treatments will move through the soil profile if it rains a good deal, which has been the case in many areas this spring.

 

“The life of a seed treatment like Cruiser or Nipsit is 21 to 35 days, depending on environmental conditions. Where Dermacor was used, you do gain longer residual activity.”

 

John Wilson, Semo Agronomy, Sikeston, Missouri

“None of my rice was lost to the flooding, although some did go under water. In one case the grower had planted but nothing had emerged before the flood came. At different times he and I dug around to try to make a judgment about whether to keep what was there. I was afraid he’d have to replant or shift to beans. But he sent me a text later saying it looked like he had a stand.

 

“None of my rice has gone to flood yet (as of 5/25), but I’m heavier on furrow-watered rice this year than paddy rice. Where growers might start watering the furrow fields, they’re scrambling to get other things done and are putting that on hold. At least right now, we have soil moisture, plus rain is in the forecast. Weed control looks okay, too. It’s been too wet to run a levee plow in a lot of the paddy rice, so that’s been a factor. Next week we will start watering furrow fields and also take some paddy rice to flood.”

 

Eddy Cates, Cates Agritech Inc., Marion, Arkansas

“We’re applying herbicides on moist soils and will apply pre-flood fertilizer as soon as the soil crusts – and then we’ll start pumping up floods. We’re right at the beginning of bringing everything to flood and are ready to get this crop moving.”

 

Wayne Dulaney, Dulaney Seed Co., Clarksdale, Mississippi

"We were able to start flooding our own rice about 3 weeks ago and my growers are taking more of their rice to flood now, too.

 

“Weed control has been pretty good. We did have to go in with some Clincher to clean up some escapes, but that seemed to be linked to how we had to make the pre-flood application. Everything had been going out by air because of all the rain, and with that field we had to make an application on only part of the acreage one day because of the wind direction. The next day when the wind shifted we came back and sprayed the rest of the field, so seeing a little gap isn’t surprising.

 

“We’ve also been working with a new grower who wasn’t able to pump up soon enough, so grass escapes turned up. We hit them with Stam and Facet and will do a final cleanup in the flood with RebelEX.”

 

Jarrod T. Hardke, Arkansas Extension Rice Specialist

“We’ve had what I’d call ‘small miracles’ where rice was under water for the better part of 3 weeks but growers still had a workable stands when the water went down. That’s not unprecedented, but you wouldn’t be surprised, either, if replanting was necessary in cases like that. The cooler weather went in favor of survivability. We also saw rice that was submerged for a shorter time but was a wreck when the water did recede.

 

“Damage from ALS herbicides has become more apparent. Cool conditions earlier kept plants from quickly metabolizing the herbicide, although symptoms weren’t obvious when the fields were under stress from weather conditions – too wet, too cool or maybe too dry at times. Once conditions improved, that rice didn’t green up as expected and ALS symptoms became obvious.

 

  

“Some farmers are behind the 8 ball in terms of pre-flood nitrogen. When all the rain and flooding started, they either didn’t have levees up or all that moving water tore them up. In places, it’s been too wet to pull levees, so that’s added to the delay. Some fields like that may be up to 6-leaf plants now, and the DD50 program says that the nitrogen should have already gone out.

 

“We’re recommending that growers put out at least some nitrogen now to keep the crop moving and also to promote tillering. That would bridge things until farmers can pull levees and make their regular application ahead of the flood.”

 

Curtis Fox, Consultant, Gillette, Arkansas

“We’re continuing to take fields to flood. Some of the weather held us up for a couple of days, but we’re still tracking along with the plan.”

 

Dustin Harrell, Louisiana Rice Extension Specialist, LSU Rice Research Station, Crowley

“A big part of our rice in southwest Louisiana is at PD now and we have a small amount of February-planted rice that’s actually heading. A little more sheath blight and blast are being reported. It’s still nothing bad or widespread, but that at least signals us to start scouting.”

 

Gary Bradshaw, Independent Agronomist, Bradshaw Agricultural Consulting, Richmond, Texas

“Our most advanced rice is at PD now, but the remainder of the crop isn't far behind. The latest fields went to flood about 10 days ago and will have joint movement in about a week. The whole crop was planted  in a fairly narrow window.  We hit a period with warm conditions and good soil moisture, and farmers took advantage of that.”

 

Bobby Golden, Mississippi Extension Rice and Soil Fertility Agronomist

“A big chunk of rice has gone to flood and more is heading that way where people can take care of pre-flood herbicides and fertilizer. Rice looks really good in plenty of fields where the flood has been established.

 

“A few more drift calls have filtered in. This continues to be a relatively quiet season as far as drift goes. We only received 3 calls this week (as of 5/25), although some substantial acreage was involved.”
