More rice is heading in southwest Louisiana and in parts of Texas.


Hot, dry weather continues to push rice but also has made it difficult to establish or maintain a flood in some areas in the Delta and Texas.


If no widespread rain falls soon in Arkansas, farmers with limited pumping capacity will have to decide whether to put water on rice to maintain floods or irrigate soybeans.


Blast has become more apparent in places. Since holding a deeper flood helps prevent blast, any problems keeping enough water on the crop could open the gate for more blast issues.

Gus Lorenz, Arkansas Extension IPM Specialist:

“We’ve started sampling for rice water weevils (RWW) in our plots. In some untreated checks we’re finding 10 to 12 larvae per 3 core samples, which is 2X to 3X what we would consider a treatment level.


“Where the flood went on within 30 days of planting, all the seed treatments are doing a good job. That includes Nipsit, Cruiser and Dermacor. Potential RWW problems could develop where rice was flooded 40 to 50 days after planting and seed treatments have played out.


“That’s why we’ve got to scout for adults and spray within 10 days of flooding. I still think a lot of RWW adults are heading towards rice and people are telling me that they’re seeing high numbers where they’re taking rice to flood. The fields that may be most at risk were planted early but didn’t grow very fast, so that stretched out the period between planting and flood.”


Harold Lambert, Independent Consultant, Innis, Louisiana:

“The rice I work is going to permanent flood – some went last week and more this week. We have a little late rice that’s up to a good stand but isn’t going to flood yet.”


Blake Foust, Consultant, Southern Heritage Cotton, LLC, Forrest City, Arkansas:

“A little rice is getting its midseason now (6/13) and we have some hybrids just now going to flood. Overall, things in the rice are pretty quiet.”


Hank Jones, C&J Ag Consulting, Pioneer, Louisiana:

“The rice crop is starting to take shape. We’ve topdressed a good bit of it. Most everything has a flood. The exception is a little hybrid acreage that was planted late because we had to wait for water to get off the field.


“We’ve had herbicide drift issues – materials moving off rice to other crops. Overall, rice is doing what it does with hot weather and a flood. Conditions have been dry and a good rain would take the pressure off growers who are trying to keep up with pumping.”


M.O. Way, Texas A&M Entomologist, Beaumont:

“We have had intermittent rains and warm weather. These rains are making timing of N fertilizer applications difficult. About 50% of our rice is at PD or beyond.


“Also, I have received complaints about delayed phytotoxicity syndrome (DPS), and it’s especially bad on hybrid rice. This disorder is an interaction between certain herbicides and a soil-borne fungus. Don Groth and Eric Webster (Louisiana State University) did a lot of work on this in the past.


“Also, I’m still seeing chinch bugs east of Houston. Our rice water weevil counts are confirming a bad infestation this year.”


Bobby Golden, Mississippi Extension Rice and Soil Fertility Agronomist:

“All of our earliest rice is nearing midseason, I think. Flooded acreage jumped up a huge amount in the last week and probably 50% or maybe even 60% of the crop is flooded now (6/13).


“We looked at a couple of incidents of Roundup drift this week and some of that rice had taken a substantial lick. We’re also seeing something that looks like delayed phytotoxicity syndrome. They’ve been talking in Texas about that being associated with Loyant but that’s not the case with what we’ve seen so far. Loyant had not been applied to that field and we’re taking soil samples to try to identify what might be happening.


“Parts of the Delta caught one of those million-dollar rains today. It wasn’t everywhere but it did help some folks. I was in one area in Bolivar County where it probably rained too much.”


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

“A large portion of our rice in southwest Louisiana has begun to head.


“The number of reported instances of blast has increased this week. Two weeks ago, in fact, no one had reported any blast at all. But then a couple of reports came in toward the end of last week and quite a few people have reported it this week.


“Most of these reports involve some medium-grain varieties and PVL01. So for our later rice, I would strongly consider two fungicide applications for susceptible varieties, especially in fields with a history of blast. Timing for the first application is at 2-inch panicle and the second is at boot split. We’re past that point with a good deal of this crop, but we still have later fields that are approaching that treatment timing.”


Jarrod T. Hardke, Arkansas Extension Rice Specialist:

“It’s still hot and it’s still dry. This weather pattern has become a concern for a lot of the Delta. We’re certainly efficient when it comes to using water but in a lot of areas this crop isn’t catching those supplemental rains. So, growers are struggling to maintain flood levels.


“If this dry weather remains in place, farmers will have to make tough choices – do they keep an adequate flood on the rice or water beans? They won’t have enough pumping capacity to do both. It’s been a long time since Arkansas farmers were forced into that corner across a large area. Where growers caught rain, it often came down so fast that much of it ran off, and in some cases forced them to replant soybeans.


“Overall, rice does look good and it’s moved fast. We just had the hottest May on record in Arkansas and racked up the most DD50 accumulation in that month for the past 30 years. It’s too early to know where we’ll be with accumulations this month, but the weather certainly isn’t cooling off to any appreciable degree.



“Blast is turning up now. With these hot nights and humid conditions, this isn’t unexpected. It seems like it came early, too. But just like the hot weather pushed DD50 accumulations, it also moved the timetable forward for blast. You can’t go by the calendar in projecting when blast might appear this year.


“We’re seeing it in typical places – along tree lines and in fields with a history of blast, for example. It’s not severe but it will pick up if these conditions persist. And the more trouble we have maintaining a flood, the more blast we’ll see. So far, I haven’t been in any rice that I’d treat, but it’s out there and we’ll have to make decisions about fungicide applications to prevent neck blast later.”


DeWayne Dopslauf, Crop Production Services, Wharton, Texas:

“We’re putting on PD applications on most of the rice. Some hybrids are starting to head. On the other end of things, one guy just started planting a hybrid and I still have organic rice going in the ground.


“We did see a little sheath blight in 400 acres of hybrid that’s starting to head. While the hybrid’s disease package covers sheath blight, the field is in an area south of Eagle Lake that has taken a hit from smut in the last several years. I’m a little gun shy about smut and don’t want it showing up on grain samples at harvest. I went ahead with Amistar Top as a preventive.


“We need rain. People with wells aren’t shutting them off and the canal companies were in a bind for a while. Cotton needs rain and what few soybeans we have are flowering and they’re at a critical point. A few pockets have been getting rain but the general moisture condition here is getting really severe.”


Amy Beth Dowdy, ABD Crop Consulting, Dexter, Missouri:

“We’re still trying to get a flood on a lot of acres and have all kinds of issues – getting levees up, catching the right conditions to spray herbicides and things like that. At one point, there was a breakdown with blending equipment and we couldn’t get fertilizer right away. We’ve had problems you might expect and then just small and random things that also held us up.


“Rice that went to flood wasn’t always sprayed in a timely manner and a lot of grass is showing up. All this dry weather is making it hard to flood. I have gumbo with 3-inch cracks and I don’t know when that rice will finally be at flood. The top of the field has been flooded for a while but the ground keeps soaking up whatever water the pumps put on it. None of our rice is at green ring yet.”
