July 2014. The Sugarcane Research Unit, Houma, LA hosted a group (29) of 6th and 7th grade students from the South Louisiana Wetlands Discovery summer camp. Support personnel provided a tour of the Sugarcane Research Unit’s Ardoyne farm.  The students had a keen interest in science and enjoyed the presentation on land loss presented by Mr. Chris Adams and Mr. Lionel Lomax.  The campers were able to instantly see what causes the loss of land and how to slow it down. Randy Richard presented a talk on entomology and shared information on the ways we check for pests, how we environmentally handle the insecticide applications, as well as our research efforts to breed for resistant varieties of sugarcane.  The campers then moved on to a presentation on pathology and disease recognition presented by Kathy Warnke and assisted by Lionel Lomax and Eric Petrie.  These young people were able to load a PCR gel with dye to see how it is done as well as observe various objects under the microscope.  Finally, the students toured the juice lab where Norris Matherne and Eric Petrie had sugarcane stalks cut for the students to run through the roller mill.  They provided a demonstration on how to collect juice from the sugarcane stalks and explained the process of analyzing the juice samples in the lab.  These young people asked probing questions and had great responses when asked questions throughout the day.

September 9, 2015. The USDA-ARS Sugarcane Research Unit would like to announce Dr. James Todd as our new Research Geneticist. Please read the following article from the September 2015, Volume 93, Sugar Bulletin. The Louisiana sugarcane industry has another reason to count its blessings. Dr. James Todd has joined the variety development team at the USDA station in Houma. He has been hired as a commercial breeder and will manage that aspect of the program. Born in Wichita Falls, Texas, Dr. Todd received his Bachelor of Science and Masters in Biology from Midwestern State University. He became interested in plant genetics during an employment at a local nursery and decided to go for a PhD in plant genetics and breeding. He enrolled at Oklahoma State University studying switchgrass breeding. In spring 2012, he was hired by the USDA to study the world collection of sugarcane and related grasses (WCSRG). He published a study looking at the use of commercial cultivars in crossing using past genealogy data in collaboration with the Houma and LSU breeding programs. James then finished his work at Canal Point and acquired another post doc position with a team planting, harvesting and collecting energy cane, then analyzing the data from the energy cane program. He is well-published and we’re glad to have him on our team.

Topics: Yields of giant Miscanthus, giant reed, and sugarcane as bioenergy feedstocks on an upland soil (Burner); In-field assessment of ratoon cold tolerance of Pennisetum and Saccharum clones (Burner); Development of orange rust of sugarcane in Louisiana (Grisham); Identifying a new causal agent of mosaic in Louisiana sugarcane (Keizerweerd); Enzymatic analysis of mannitol as a measure of post-freeze juice degradation in sugar and energy cane (Hale); Effect of potassium fertilizer application on sugarcane yields in Louisiana (Johnson); Use of SSR markers for DNA fingerprinting and diversity analysis of Pakistani sugarcane (Saccharum spp. Hybrids) cultivars (Pan); and Cultural practices to increase ratooning (Viator).

June 4, 2013. Thirteen campers (ages 8-13), along with 4 instructors, from the South Louisiana Wetlands Discovery Camp visited the Sugarcane Research Unit’s (SRU) research farm in Schriever, LA. Dr. Paul White demonstrated how soil cover affects erosion using a rainfall simulator and special troughs and funnels. Mr. Harold Callahan and Mr. Hubert Zeller demonstrated how the slopes of our fields are regulated to reduce soil runoff using laser guided grading equipment. Mr. Randy Richard talked about the insects of sugarcane and how we have both good and bad ones in our environment. Ms. Kathy Warnke and Ms. Jeri Maggio discussed the disease problems in our industry and allowed the campers to load a PCR gel with dye to demonstrate the tools used to diagnose plant diseases as well as to look under the microscope to see the spores of rust disease. Mr. Eric Petrie explained the process of analyzing the juice in our lab and the equipment needed to complete this task. The group boarded a trailer and took a ride through the cane field to see firsthand what they had just learned about.

June 1, 2013. The LaTerr Master Gardeners, an extension based group, along with USDA Peoples Garden Project hosted a Vegetable Field Day for the local community on the grounds of the Sugarcane Research Unit in Houma, Louisiana. One hundred and twenty people turned out for the occasion and viewed the garden plots containing many varieties of tomatoes, peppers, eggplants, squash, beans, corn, and a variety of flowers. Presentations were made by several extension personnel as well as USDA member Mr. Eric Petrie who acts as the liaison between the two agencies. Those in attendance were given the opportunity to ask questions, share their successes, taste many of the varieties of tomatoes, and rate their flavor. This is the 4th year the USDA has partnered with this group and employees enjoy sharing their knowledge with the community. Most of the produce that is harvested is donated to the local food bank.

May 31, 2013. ARS Scientists and support staff from the Sugarcane Research Unit participated in the USDA-LSU AgCenter Sugarcane Field Day at the USDA Ardoyne Research Farm, Schriever, LA. Attendees toured the SRU’s newest facilities – Crossing & photoperiod house and head house & storage buildings. The following topics were presented throughout the day: Varieties (Edwis Dufrene), Soil fertility management: prioritizing inputs to maintain yields and insure profitability (Johnson); Billet and whole stalk planting and planters (Viator); Sugarcane varietal competition with johnsongrass and bermudagrass (Dalley); Intercropping and soil additives for improved soil health (Paul White/Chuck Webber); and Report on Spring 2013 Seedling planting (David Burner). Presentations were also made by employees of the LSU AgCenter (Mr. Rick Louque and Dr. Michael Salassi), and the American Sugar Cane League (Mr. Jim Simon).

May 23-27, 2013. Drs. Anna Hale and Yong-Bao Pan, Sugarcane Research Unit, Houma, LA were invited to speak at the International Workshop on Noblisation of Erianthus in Fiji, sponsored under the European Union African Caribbean Pacific (EU-ACP) Sugar Research Program. The workshop was organized by the Sugarcane Research Institute of Fiji (SRIF) and observed by Program Coordinator Mr. Jean Cyril Dagallier from Belgium. Dr. Hale’s presentation was entitled, “The use of Erianthus in the USDA’s germplasm enhancement program in Houma, Louisiana”. Dr. Pan’s presentation was entitled, “Effectiveness of molecular techniques in identification of Erianthus hybrids”. Ten sugarcane breeders and four molecular geneticists from nine countries were invited to the workshop to deliberate and share experiences on Erianthus hybrid production.

May 13 – 17, 2013. Dr. Richard Johnson of the Sugarcane Research Unit, Houma, Louisiana was invited to present aspects of his research in precision agriculture to the staff of El Viejo Sugar Mill and Plantation, in Guanacaste, Costa Rica. Dr. Johnson was also asked to evaluate the sponsor's current precision agriculture operations and provide input and suggestions for their improvement.
