Today I received this information from Keith A. Fontenot, County Agent, Evangeline Parish. I am not on the program to speak at this meeting, but I will be there to distribute our annual rice entomology survey and to answer any questions you might have about pest management in your rice crop.



Wednesday, January 4, 2012– Registration at 7:30 a.m.

Ville Platte Civic Center

Two of Evangeline & St. Landry Parish’s most economically important crops will be discussed at length at the 52nd Annual Rice Production School and 45th Annual Soybean Production School.  These production schools will be held together on Wednesday, January 4 with registration beginning at 7:30 a.m. at the Ville Platte Civic Center.

Topics to be discussed by specialists and researchers with the LSU Agricultural Center will center on updated production practices concerning both crops.

Recertification is also offered on this day to all producers or homeowners needing recertification of their Private Pesticide Applicators Card.   If you register, pay the $25.00 fee and attend the entire meeting, you will be recertified as a private pesticide applicator for another 3 year period.

These private applicator re-certification meetings will also be offered in February.  At the meetings in February you will only be required to stay 1 ½ hours to be re-certified.

The program agenda and speakers are as follows:

Rice water weevil (RWW) management demonstrations have been conducted for the past four field seasons. The purpose of these demonstrations is to evaluate currently recommended insecticides on commercial rice farms in Louisiana to control RWW. These trials are a joint effort between county agents, farmers, consultants, seed dealers and chemical distributors. In 2011, we compared three insecticide seed treatments (CruiserMaxx, Dermacor X-100 and NipsIt INSIDE) to an untreated check. Each treatment was planted in two strips at each location. A total of 6 locations were included in the 2011 demonstration test. The commercial farms were located in Acadia, Calcasieu, Evangeline, Jeff Davis, Rapides and St. Landry parishes. We took stand count data 2 weeks after seedling emergence at five locations and RWW core samples (10 cores / plot) 4 weeks after permanent flood to assess the relative efficacy of treatments at all 6 locations.

The on-farm demonstrations were conducted in the parishes indicated in purple.

At five of the six locations we planted the variety XL745. Thus, the seeding rates were low and the results of our study may not translate to field planted at a higher seeding rate (more than 25 pound seeding rates).

We found no significant difference between stand counts. Plant heights were significantly greater in CruiserMaxx and Nipsit INSIDE treatments than in Dermacor X-100. When we analyzed the RWW core sample data we found that all seed treatments had significantly fewer RWW larvae per core than the untreated check (average 12.9 RWW larvae/core). Dermacor X-100 (average of 2.5 rww larvae/core) provided the highest level of control, whereas Nipsit INSIDE (average 7.9 larvae/core) and CruiserMaxx (average 7.9 larvae/core) provided intermediate levels of control.

We conclude from these observations that if you are planting rice at low seeding rates (less than #25) and decide to use a neonicotinoid seed treatment (CruiserMaxx or Nipsit INSIDE) you should scout the field at the time of flood for the presence of rice water weevil adults. If you find a high population of rice water weevil adults, you may want to consider applying a pyrethroid to provide additional protection from rice water weevils. However, if you use Dermacor X-100, be aware that it does not provide protection against other early season pests such as thrips, aphids, and Colaspis.

This project was coordinated by Natalie Hummel, Anna Meszaros and Mike Stout. Thank you to all of our cooperators: LSU AgCenter County Agents: Barrett Courville, Trent Clark, Vince Deshotel, Rob Ferguson, Keith Fontenot, Matt Martin, Jimmy Meaux, Dusty Zaunbrecher; Rice farmers: Chris & Randy Dauzat, Charlie Fontenot, Johnny Hensgens, Kenneth LaHaye, Glen & Wes Simon, Mark Stelly, Bill Wild; Crop Consultants and Company Representatives: Rusty Elston, Dennis Fontenot, Kent Guillory, Rustin Gilder, Cullen Minter, Dean Reed, Randy Verret; our Field Crew: Nick Colligan, David Albano, Jordan Fryoux, Marty Frey and the rice station entomology crew. Finally, we could not have completed this project without the financial support of the Louisiana Rice Research Board, DuPont, Syngenta and Valent.

I’ll discuss these results in the rice winter meetings. How did the seed treatments look at your farm?

As you may recall, we received approval for a Section 18 registration for Tenchu 20SG to control rice stink bug in Louisiana rice. This approval came very late in the season when most of the southern crop was either harvested, or well on it’s way to harvest. Fortunately, we were able to work with a team of county agents to line up some field locations and compare the efficacy of Tenchu 20SG to pyrethroid treatments. Here is a brief report of what we learned.

Nine field sites across Louisiana were identified for participation in the demonstration program. At all locations two adjacent fields or cuts were sprayed separately with a pyrethroid or Tenchu 20SG. Sweep net samples were taken within 24 to 48 hours prior to spraying at each site between the growth stages of anthesis and hard dough. Insecticides were applied by aerial applicators at recommended rates for both products: 8 oz/ac of Tenchu 20 SG, 2 oz/ac of Karate, and 4 oz of Mustang Max. Additional sweep net counts were taken at 48 hours and 7 days after treatment to determine residual effects of either treatment against infestation of RSB. The pyrethroid portion of one field site remained above threshold at the 48 hour sampling point and was treated with a second application at 48 hours to prevent further damage. Samples of rough rice were collected from all treated sites at harvest and analyzed by a USDA certified inspector at Bertrand Rice in Elton, LA to determine percent pecky rice and determine the USDA grade of the sample.

We analysed the data in SAS using a Proc Mixed Procedure. The average number of RSB per 10 sweeps was not significantly different when analyzed by treatment or time. There was no significant difference in the percentage of peck between treatments, and no grade reductions were applied to any samples gathered.

Thus, we concluded that either Tenchu 20SG or pyrethroids, when applied appropriately, both provided good control of RSB and prevented grade reductions due to peck in our demonstration test. We are continuing to conduct research on rice stink bug thresholds and treatment strategies. I’ll talk about these results at the winter production meetings in 2012. We will also present these results in a poster at the Rice Technical Working Group meeting in 2012.

Special thanks to all our demonstration cooperators: Floyd Baker, David Bertrand, Keith Collins, Richard Costello, Chris & Randy Dauzat, Barrett Courville, Rusty Elston, Terry Erwin, Eddie Eskew, Rob Ferguson, Noble Guedon, Michael Hensgens, Nan Huff, Ron Landis, Mitchell Leger, Cecil Parker and Larry White.

This project was coordinated by Bryce Blackman, Mike Stout, Anna Meszaros and myself.
