Silicon amendments may provide sustainable control for rice water weevil

A Masters student at Louisiana State University is seeking a more sustainable way to manage rice water weevil, by amending soils with silicon to strengthen the plant. He is also this year’s winner of the Friends of Southern IPM Graduate Student award in the Masters category.

Rice water weevil is a tiny insect that feeds on the rice plant’s leaves as an adult. After mating, females lay their eggs at the base of the plant. Larvae feed on the roots. The larval feeding on the roots potentially interferes with the nutrient uptake, thereby, weakening the plant. Root damage can cause yield losses through decreasing panicle densities, number of grains, and grain weight. Rice growers use insecticides to control rice water weevil. Continue reading

Exotic snail poses threat in Louisiana and Texas

In Delta Farm Press

The apple snail, an exotic pest causing problems for Louisiana and Texas rice and crawfish operations, likely became established as a result of aquarium owners dumping the large snails.

The pests pose a double threat — they have a big appetite for vegetation, according to specialists at Louisiana State University. They also clog crawfish trap openings and tunnel through rice levees. Continue reading

Farmers heard the news at a field day held June 14 at the LSU AgCenter H. Rouse Caffey Rice Research Station South Farm in Crowley. Continue reading

Field Crops Entomologist position available at Louisiana State

WORK LOCATION: The position will be based at the Tom H. Scott Research and Extension Center near Winnsboro, LA. Opportunities for research and extension activities exist at three research stations in the Region and in the Department of Entomology on campus in Baton Rouge, LA. The Regions’ field stations include over 1,000 acres of crops with research and extension demonstrations focusing on agronomic production and integrated pest management of arthropods, plant pathogens and weeds. Research projects will be located at both research stations with opportunities to expand that work to other regions of Louisiana. Laboratory and office space will be available in the Department of Entomology.

POSITION DESCRIPTION: Full-time 12 month, tenure-track position with a 70% extension and 30% research appointment. The successful candidate will be responsible for the development and implementation of pest management programs for insect pests of field crops in northeast Louisiana, including corn, cotton, soybean, and grain sorghum. The extension component will also include statewide contact responsibilities for one or more of these primary commodities. The position will provide leadership and work with producers and other LSU AgCenter personnel to plan and organize a well-balanced Extension educational program. The scientist is responsible for working with advisory committees to identify clientele needs, to develop programs that respond to those needs, and to assess program impact. The position will disseminate LSU AgCenter recommendations and provide current content to commodity web pages. Technology transfer and outreach to stakeholders must be accomplished with web content, social media, agricultural trade magazines and traditional extension methods (newsletters, blogs, oral delivery and formal extension publications).
