This year EPA approved a section 24C approval to use Dermacor X-100 in water-seeded rice in Louisiana. [Click here for a blog post about the registration.] Quite a few producers used this insecticide option in water-seeded rice in Louisiana this season. Mike Stout had extensive research data to support the efficacy of Dermacor in water-seeded rice, but I felt it would be good to verify the activity in commercial fields. Dr. Saichuk used this treatment option at the Vermilion Parish LSU AgCenter rice verification field. According to Johnny, the Dermacor rate was 1.75 oz/A. The variety Cheniere was planted on 4/5/2012 at 120 lbs/A. A true pinpoint flood was applied to the field. Nick Colligan and Stuart Gauthier pulled ten core samples from the field 4 weeks after permanent flood to verify the activity of the insecticide. Nick reported that they did not find any rice water weevil larvae in the core samples gathered.

On another note, one of the field reps reported that they are starting to see armyworms in vegetable gardens in Grand Chenier. I have not received reports of armyworms  in Louisiana rice yet, but it would be good to be on the lookout for this pest. If you treated with Dermacor X-100, the rice should be protected from injury, but CruiserMaxx or NipsitInside will not control army worms. Click here to read about armyworms in rice.

I know that quite a few of the rice consultants in Louisiana now have iPads that they are carrying around with them in the field. The utility of this tool can be enhanced by downloading apps for a number of uses. AgCenter faculty are currently developing a mobile tool called “RiceScout” that should speed up the process of rice in-field diagnostics.

The LSU AgCenter Southeastern Region Director, Dr. Bobby Fletcher, recently sent me a link to an iPhone app search tool. This tool was developed by the University of Arkansas as an aid in the search for agriculturally related apps. You can find a link to the tool here: http://www.uaex.edu/news/april2011/0408AppSearch.htm If you try out this tool, please let me know if it is useful.

Stuart Gauthier, LSU AgCenter County Agent in Vermilion Parish, recently announced a Vermilion Rice Growers meeting and verification field tour with Dr. Johnny Saichuk. I plan to talk about rice insect management and address any questions from producers. All are welcome to attend. Please contact Stuart at sgauthier@agcenter.lsu.edu if you plan to attend the meeting.  The group will gather at Suire’s Grocery Store (13923 La Highway 35, Kaplan, LA 70548) at 7 am on Tuesday, April 26, 2011. Following a brief Vermilion Rice Growers Meeting, we will travel to Josh Newman’s Verification field (departing around 8 am). 

Hope to see you at the meeting.

Scouting for borers with Fred Cramer, a Vermilion Parish farmer, and County Agent Stuart Gauthier (Photo by Jarrod Normand).

Is anybody starting to see borers in the field?  They might start to come on as the crop approaches boot.  We recommend that you begin scouting for borers at green ring and intensify scouting as plants get closer to or reach early boot stages.  Look for feeding lesions on the inside surface of the leaf sheath.  If you locate a feeding lesion, check for frass to ensure it is stem borer and not sheath blight damage.  You should also scout for adults, egg masses or fresh feeding scars on the leaves.

To learn more about scouting for borers in rice, please visit the following LSU AgCenter websites:

The LSU AgCenter publication: “Rice pests of Louisiana” contains photographs of rice stalk borers, sugarcane borers, and European corn borers.  This can be accessed at the following link: http://tinyurl.com/3yk458b

For sugarcane borer information see: http://tinyurl.com/3xrsdnm

A powerpoint on European Corn borer and other borers in rice can be found at: http://tinyurl.com/34gvxyt

The Mexican rice borer (MRB) has not been reported in Louisiana since the original detection in December, 2008.  It is important that we remain vigilant in monitoring for this pest.  Please refer to the following ID card for photos of the MRB larval stage: http://tinyurl.com/33ml44r

If you treated your rice with Dermacor X-100 you should have control of borers, but I would still monitor the field because we have limited borer efficacy data in Louisiana.  If you plan to use a pyrethroid to control a borer infestation, it is necessary to apply the foliar treatment before the borer penetrates the stalk/stem.  Once you start to see whiteheads in the field, it is too late to treat for borers.

Yesterday, County Agent Stuart Gauthier pulled core samples at the test site farmed by Alden Horton.  Alden wanted to really study the management of rice water weevils in a water-seeded system.  In this case, the only option for pesticide management is the use of pyrethroids.  The first step was to spend the time to scout properly before and after permanent flood for the presence of rice water weevil adults.  Stuart worked closely with Dr. Saichuk, myself and Alden to check the field on a regular basis – at least weekly, but often times more frequently.   It was a tough decision to decide on weevil management at this site. 

Permanent flood was applied on April 23, 2010. We scouted before flood, did not find weevils, so we decided to hold off on spraying.

On May 6, 2010, Stuart scouted the fields with Johnny and Alden.  At this time, the rice was at mid-tillering and rice water weevil adults (including mating pairs) were found in the field.  The population was sparse, but there are often many more that you don’t see.  We recommended an application of 2.0 fl oz of KarateZ.  Two small cuts that were separated by levees from the treated fields were left untreated for comparison.

We gathered 10 cores per field 4 weeks after permanent flood.  This is when you will see a peak in the population.  We processed the cores at the rice station yesterday – 10 cores per field – untreated and Karate treated.  In the untreated check, the average number of larvae per core was 4.8.  By comparison, the Karate treated field had a population of 0.9 larvae per core.  Much research has led us to conclude that each larvae can cause 0.5 to 1.5% yield loss.  Based on this estimate, we would predict that a yield loss from 2.4 to 7.2% may be experienced at this field site.  It appears that a treatment was called for at this location.

We’ll let you know how it looks as the season progresses.  We will probably have a stop here at the Vermilion Parish rice tour on July 6, 2010.

Our sincere thanks go to Mr. Alden Horton for cooperating in this demonstration test.
