Here is this week's issue of AgFax Rice.

A small amount of heading may have started in southwest Louisiana in early planted fields.
More rice is going to flood in the Midsouth, with a little rice already at permanent flood in Missouri.
Sporadic rains continue delaying progress in parts of the Midsouth, especially in the upper Delta.
From Our Sponsor
Gus Lorenz, Arkansas Extension IPM Specialist:
“Grape colaspis injury has been pretty bad in parts of the state where people went without seed treatments. The colaspis can carry over from the previous year’s soybean crop and in places you can pick out last year’s soybean rows where they’ve injured rice plants.
“This has mainly happened in the Arkansas River Valley and on the Grand Prairie. Again, these are cases where seed wasn’t treated. Some soybeans were torn up around DeWitt by colaspis, too. This also has been one of the worst years in some time for wireworms. Considering that and the issues with grape colaspis, it seems like soil pests are having a good year.
“Wireworms got into cotton a little but more so in grain sorghum and corn. Wireworms were bad in some corn where lower rates of seed treatments were used. The treatments didn’t hold up in a lot of cases because wireworm numbers were so high.”
M.O. Way, Texas A&M Entomologist, Beaumont:
“We’ve had plenty of hot weather lately and the crop looks good. Rice is approaching PD on a wide basis and some will be heading out in 1 to 2 weeks. In general, the crop keeps looking better and better.
“I have observed chinch bug injury in some rice in Chambers County. That rice received an insecticidal seed treatment that would have controlled early infestations but the activity has played out by now (5/30). I’m still noticing some adult rice water weevil scarring in places. One crop consultant said he’s having some problems with escaped sprangletop following Command.”
Scott Gifford, Gifford Crop Consulting, Manila, Arkansas:
“We’re going to flood on less than 25% of our rice right now (5/29). But if the rain holds off and we can get fertilizer out and spray the rest of this week, we should have 75% at flood by the weekend. Everything depends on whether and where it rains.
“It keeps raining in places where we need to clean up grass and broadleaf weeds. On top of that, herbicide applications have been on hold in places because of wind and surrounding crops. Overall, the crop does look very good, other than where we have to clean things up. We can’t catch a break with the weather.”
Andy Tonos, Delta Ag Consulting, Greenville, Mississippi:
“We started flooding up some rice 7 to 10 days ago (from 5/30) and the rest is going to flood now. Most rice was planted pretty early. We’ve got about 300 acres that are only at 2 to 3 leaves but that’s the exception.
“Rice is going alright, although things haven’t run quite as smoothly as they did last year. In 2017, it seemed like we got everything sprayed and didn’t have to spray much of it again before we flooded. This year, though, rice grew slower in that early cold weather. Preemerge herbicides seemed to play out fast but rice was still too small to go to flood. That forced us to spray again.
“This rain has further complicated things in places. On one farm, it’s rained every week. The grower planted in the mud, pulled levees in the mud and put in gates in the mud. I just hope he doesn’t have to harvest in the mud, too.”
Ashley Peters, Peters Crop Consulting, Crowville, Louisiana:
“Between last week and this week, a lot of rice has been going to permanent flood. Later this week or early next week we’ll be looking at some topdress applications. Rice is moving along pretty rapidly. These hot and sunny days have really fueled growth.
“We’re not catching rain, so we’re keeping water moving to it. Any rain lately has been scattered and highly variable – 5 inches in one place and 5 tenths of an inch just down the road.”
Hugh Whitby, KC Consulting, Wynne, Arkansas:
“We’re trying to go to flood with everything. We’ve been behind due to the weather. We flushed most of our rice about 3 weeks ago (from 5/31) because it had gotten so dry, plus we flushed in another residual and also fertilized. Then we got caught by the rain, which meant we were having trouble getting the fields dry.
“But we’re going to flood this week with a lot of rice. By the end of next week, we should have everything flooded. Most of our soybeans are planted and what I call our first post application has either gone out or is being sprayed this week.”
Wendell Minson, Bootheel Crop Consultants, Dexter, Missouri:
“Maybe one or two fields are at permanent flood now (5/31) and we’re trying to move more rice to flood. The crop looks pretty good and we haven’t had many big issues. Growers are trying to pull levees, spray to clean things up and begin pumping. Where these little showers fall on heavy gumbo, you can’t jump in right away and pull levees, so that’s delaying things here and there.
“Overall, though, we’re not too wet or too dry. Maybe we’re just approaching the point that we need a rain. Weed control has been good.
“In soybeans, the deadline for making dicamba applications here is June 10, and guys are spraying around where they can and applying residuals. It’s been wet enough that people couldn’t always jump in and treat when they wanted, so weeds may be an issue in some soybeans and those growers will have to go the extra mile to clean up parts of the crop.”
Dustin Harrell, Louisiana Rice Extension Specialist, LSU Rice Research Station, Crowley:
“Rice in southwest Louisiana looks beautiful. We’ve moved past midseason on a wide basis and are just a couple of weeks away from heading. I’ve heard a few reports of earlier rice already starting to head.
“So, it’s time to scout for diseases in this part of the state. No reports of any issues yet. These conditions – low humidity, high heat and dry weather – are the perfect scenario for low disease pressure. Still, though, you need to scout. We posted a quick overview on managing blast, sheath blight and other common diseases. Review that as a starting point this year as we move into the main disease phase.
“Also, a reminder: our annual rice research center field day is coming up on June 27 in Rayne.”
Bobby Golden, Mississippi Extension Rice and Soil Fertility Agronomist:
“We’re probably 20% flooding and that’s picking up steam every day. With a lot of fields, we’re putting on the final herbicide and getting fertilizer out ahead of flooding.
“Preflood fertilizer applications have gone smoothly. The ground has been dry and we haven’t had any of those rain-related issues like we normally expect. My colleague Jason Bond (Extension Weed Specialist) said just now (5/31) that this is the quietest year for putting in a rice crop in Mississippi that he can remember. I concur.”
Jarrod T. Hardke, Arkansas Extension Rice Specialist:
“We’ve got the hammer down – trying to spray, apply fertilizer and flood. Probably half the crop is there or in the process and we’ll be pushing on that for the next 2 to 3 weeks as more rice is ready or conditions allow.
“The heat is really driving the crop forward. Obviously, a lot of rice wasn’t planted until the last few days of April and into early May, but that rice has progressed faster than we tend to expect. It came up in 5 to 7 days and kept going. We’re making tremendous strides moving that part of the crop to flood.
“Unfortunately, the wind isn’t doing us any favors. The right conditions for applying herbicides have been limited, at best. We’re starting on some mornings with so little wind that it’s flirting with inversion-type conditions, then the wind finally starts moving enough that you think you can spray. But suddenly it jumps to 15 mph.
“The time between those extremes – too little wind and too much wind – is too brief in many cases to do much serious spraying. Obviously, we’re worried about preventing herbicide drift but the wind has picked up enough at times that aerial applicators are pulling back on applying fertilizer because they’re worried about streaking.
“We still continue catching these scattered, random showers, more so in the northeast and northern half of the state than in south Arkansas. That’s delaying progress on plenty of acres. We’re also still dealing with those decisions about applying fertilizer when soils are muddy or wet. I’m not getting as many calls about that as a week or two back but it’s still a concern for growers who seem to get most of the rain that comes along.
“Here’s the kicker. More rain is in the forecast for tonight (5/31). A system suddenly turned up in the forecast this morning. Several counties are in a bullseye where 1.5 inches of rain might fall. That includes parts of north-central and northeast Arkansas where the last thing anyone needs is more rain.”
