County Agent Donna Lee (East Carrol Parish) hosted a field meeting at the farm of Mr. Garrett Marsh in Madison Parish in cooperation with County Agents RL Frazier (Madison Parish) and Dennis Burns (Tensas Parish).  We started bright in the morning and the rice was busy shedding water in the heat.  Dr. Johnny Saichuk described this in a field note a few weeks back.  (in case you didn’t already know this – you can click on the pictures to enlarge the image size on your computer screen)  

These droplets of water are called guttation - the rice is releasing excess water in the morning. This is what causes high humidity around rice fields in the early morning hours.


These high humidity conditions pose a bit of a challenge when taking pictures, but there were way too many critters to miss the chance.  The rice is just starting to head and the rice stink bugs were poised and ready to strike.  

Rice stinkbugs are light tan in color with points on the corners of the pronotum.


Remember that the threshold for treatment in the first two weeks of heading is 30 per 100 sweeps, and after the first two weeks of heading to hard dough is 100/100 sweeps.  Be sure to observe preharvest interval restrictions.  Mike Stout and I are co-advising a graduate student who is studying rice stink bugs.  We may be revising thresholds in the future.  

We had walked out in the field to look at some suspect red rice – this is easy to spot because it usually has a light yellow color, pubescent (hairy) leaves, and awns when the panicle emerges.  Johnny recommended rouging the weedy red rice out of the field before it has the chance to go to seed.  A big problem can grow from a small patch of plants.

As we were examining the red rice I couldn’t help but notice an abundance of long-horned grasshoppers in the field.  This included adults and immatures.  In most cases, even if the grasshoppers feed on rice they won’t do enough damage to warrant a spray, but sometimes they can be severe.  This is a good thing to be on the look-out for as your are scouting your rice.

Before we had even driven to the field, the farmer – Mr. Garrett Marsh had mentioned some small black and white insects on the Johnsongrass at the edge of the field.  As I had suspected, these were chinch bugs.  Chinch bugs can be sneaky pests that prefer to hide down inside the sheath of plants.  As we examined the weeds, we found a variety of life stages from nymphs to adults.  

Notice the difference in coloration from the nymph to adult stages. Nymphs molt (shed their skin) to go from orange, to orange with tan band, dark brown with tan band, to finally the black adult with a white hourglass.


This is what chinch bugs often look like when you are scouting for them in grasses - this is the rear view of an adult hiding out in the leaf sheath to avoid the heat.


Notice the distinct hour glass that you can just barely make out from the rear view of the chinch bug adult.  At this stage of the game, there is no need to treat for chinch bugs even if they were in the field.  Although, I have had some reports of chinch bugs causing damage to panicles in headed rice – Johnny Saichuk featured this damage in his field notes.  It is good to remember that insects do not follow rules and will many times surprise us with what and when they decide to damage the crop.  

This week we have field meetings in Vermilion Parish (Tuesday afternoon) and Richland Parish (Wednesday morning).  Please contact county agents Stuart Gauthier or Keith Collins for more information.

UPDATE: Additional information about the field day (including an online presentation of the field tour and speaker session) is available at www.lsuagcenter.com/ricefielddayinfo. 

The forecast calls for a chance of rain in the Crowley area tomorrow morning. In the case of rain, all field day activities will be held in the poster pavilion/drier area. Field tour speakers will make their presentations inside the drier beginning at 8:30 a.m. All other activities will be as scheduled. 

This is a busy time of year for field meetings.  Field days and workshops are a great opportunity to see research and extension programs conducted both at the research stations and on cooperator farms.  I hope to see many of you at these upcoming events.  

June 30.  Hundley Master Farmer Field Day/Ricetec Field Day, Mowata La., 5:00 PM.   

This field day will report the results of a small plot evaluation conducted by RiceTec.  This location evaluated varieties and also included a rice water weevil insecticide rate test.  My weevil crew gathered samples from the small plots 4 weeks post flood.  The results of the test will be presented.   Attendance at this field day will also count as Phase II and Continuing Education for producers wanting to get credit in the Master Farmer Program.  

For more information, please contact Cullen Minter at 336-499-6489.   

July 1.  101st Annual Rice Research Station Field Day.  Rice Reseach Station, Crowley, La. Beginning at 7:30 am.   

The LSU AgCenter Rice Research Station Rice Field Day will be held on Thursday, July 1, 2010 at the station.  The activities will begin at 7:30 a.m. with field tours of research projects, with the last tour truck leaving no later than 9:15 a.m.  Mike Stout and I will give an update on the Entomology Research and Extension Programs.  

There will be a poster session under the equipment shed on the west side of the drier. The poster session will last from 7:30 to 10:30.  During this time researchers and Extension specialists will be discussing and explaining their research programs, the methods used and the results they have attained thus far.    

Much of the field day program will focus on historical aspects of rice production technology developed through the years at the research facility. The main program will start at 10:45 a.m. in the drier facility with a lunch following.  

For more information, please contact Dr. Linscombe at slinscombe@agcenter.lsu.edu or 337/788-7531   

July 6.  Vermilion Rice Field Tour.   Gueydan and Klondike Area.  Beginning at 3 pm.

July 9. East Carrol Parish Rice School.  School will be held in Madison Parish on the farm of Garrett Marsh, approximately 4 miles north of Tallulah on Hwy 65.  Program will begin with registration at 7:15 am.  

Donna Lee and RL Frazier have coordinated an in-field rice school in Madison Parish.  Speakers at the training will include Bill Williams (weed scientist), Johnny Saichuk (state rice specialist) and myself.  We will discuss the latest Research and Extension rice information.  

For more information, please contact Donna Lee at drlee@agcenter.lsu.edu.  

July 14.  Richland Parish Rice Field Day.  Rayville, La.   

There will be a variety of speakers on the program.  I will discuss the results of the rice water weevil demonstration and anything else we are observing in the field.   

For a schedule and directions to the field, please contact Keith Collins at kcollins@agcenter.lsu.edu
