For several years Arkansas rice farmers have had to deal with grape colaspis, a small beetle, whose larvae feed on the roots of rice. Rice drilled into soybean stubble is particularly susceptible to damage from this insect. Larval feeding can cause more than 50 percent reduction in stand. This season colaspis has caused stand reductions in a few rice fields in Acadia, Evangeline and St. Landry parishes. This short video will train you to scout for colaspis in rice. (Runtime: 3:58)

The rice water weevil (RWW) is the most important early-season insect pest of rice in Louisiana. Adults of this insect emerge from overwintering sites beginning in early April in southern Louisiana (later in northern Louisiana) and fly to rice fields, where they feed on young rice leaves.

(Distributed 09/05/08) Rice is among the many Louisiana agricultural commodities hurt by Hurricane Gustav, although the majority of the crop had been harvested in the southwest Louisiana rice belt before the storm came through.

(Distributed 09/09/08) WHITEVILLE – Farmer Jeffrey Sylvester gazed over a field that looked more suited for water-skiing than growing rice. “There’s a rice crop under that water,” he said. “That’s all standing rice.”

Cattle, rice, sugarcane, crawfish, wildlife and alligators are among many of Hurricane Rita casualties in southwestern Louisiana.

Farmers attending workshops in Acadia and Calcasieu parishes Tuesday (Oct. 25) learned about assistance for dealing with hardships caused by two hurricanes that struck the state this summer. Similar sessions, organized by the LSU AgCenter, were planned for New Iberia, Hammond and Raceland over the next few days.

Vermilion Parish rice farmer David Lacour emerged from a rice bin recently, covered in sweat and dust.

This report presents estimates of production costs for rice production in Louisiana for the 2008 crop year. Costs estimates are included for typical rice production systems, including conventional tillage, stale seedbed, production in rotation and fallow, as well as production of conventional and herbicide-resistant varieties. Production cost estimates are also included for soybeans, wheat and sorghum in Southwest Louisiana.

Rice farmers whose fields have high salt levels from Hurricane Rita’s storm surge should avoid plowing their fields, according to experts with the LSU AgCenter.

Irrigation ponds can irrigate fields during the summer without resorting to pumping water from wells.

Recent rains have drenched Louisiana, and the outlook is not good for the state’s rice crop. Corn and wheat also have taken a beating – but specialists believe the Louisiana cotton crop may have weathered the storm. Double-digit rainfall was recorded in many areas of the state over the past couple of weeks, and totals exceeding 20 inches were seen in some places. Observers even reported as much as 24-27 inches in spots.

(Distributed03/27/03) Rice planting has begun in South Louisiana, but many farmers in the central and northern parts of the state are looking for options because they’ve been delayed by persistent rains and wet field conditions. That’s where the state’s aerial applicators – pilots with specially equipped aircraft – come in. And many of those aerial applicators take advantage of LSU AgCenter services that help them check their equipment.

The development of Clearfield rice, which is tolerant to imidazolinone herbicides, is the most important advance in rice weed management in recent years.

LSU AgCenter weed scientists began working with Grasp in 2003, but it wasn’t until 2004 that in-depth research could be conducted because of limited product availability.

Rice diseases pose a major threat to rice production. The two major diseases, sheath blight and blast, cause significant yield and quality reductions that cost farmers millions of dollars each year.

Will the South American rice leaf miner be affected by salt water pushed ashore by Hurricane Rita? LSU AgCenter entomologist Dr. Boris Castro said it’s possible the rice pest’s population could have been weakened by the high salinity, but there’s no way of knowing yet.

South Louisiana rice fields contaminated with salt from Hurricane Rita’s storm surge have shown some improvements, although not as much as expected, and salinity levels actually have increased in some sugarcane fields.

Farmers are facing uncertainty with expected changes in U.S. farm policy, high energy costs and World Trade Organization talks, a Washington agricultural analyst told rice producers last week (Jan. 26).

This study was designed to examine the biological and economical efficacy of relaying crawfish into a growing rice crop in an intercropping manner.

LSU AgCenter researchers are studying the effects of salt water in rice after many fields were flooded during Hurricane Rita. The study started with extensive soil sampling of affected areas. LSU AgCenter agronomist Dr. Gary Breitenbeck explains. (Radio News 12/12/05)

LSU AgCenter scientists hope they will soon be able to make recommendations for farmers whose fields were hit with saltwater contamination from Hurricane Rita’s storm surge.

Grooving is a technique for planting rice. Seeds fall fall into shallow grooves seven inches apart, which keeping them in place even in windy conditions.

Beyond, made by BASF, is intended for an early post-emergence application between tillering and panicle initiation to control red rice not killed by two applications of Newpath herbicide. Beyond, intended to be used only on Clearfield 161 and XL8 varieties, is in the same chemical family as Newpath.

Great prices and good weather have generated plenty of optimism.

Excessive moisture from heavy rainfall has set the stage for disease problems in rice fields. Conditions will be prime for fungal diseases, principally sheath blight and blast.

Louisiana farmers will plant more acreage in rice, soybeans and cotton but less in corn.

(Distributed 03/21/03) Robert Thevis calls himself a rice farmer, but the 2003 Louisiana Farmer of the Year grows much more than rice. Thevis farms nearly 2,000 acres in Avoyelles Parish – raising soybeans, corn, milo and, when the weather allows, winter wheat. As a reward for his efforts, he received the state's farmer of the year award Friday evening (March 21).

Applied properly, Newpath herbicide is an effective remedy for red rice and grasses in Clearfield rice. It's important to spray insecticide after finding rice water weevils because the only pesticides authorized for use after planting are for adults only.

Clearfield 161 tolerates Newpath extremely well, allowing more flexibility for the application timing. With the early versions of the seed, farmers had to spray before emergence and then wait until the plants reached the 4-leaf stage. But 161 allows farmers to apply Newpath after emergence and before the 4-leaf stage, which allows for better red rice control.

(Distributed 04/23/04) LSU AgCenter entomologist Dr. Michael Stout is studying three chemicals that could be used as seed treatment replacements for Icon to fight rice water weevils. Stout is also studying two proposed granular chemicals.

The project combined construction of a new administration building and remodeling the remainder of the old structure, which was built in 1954. The new facilities are symbolic of the top-notch effort under way to help the state’s rice farmers.

The U.S. Environmental Protection Agency recently approved gamma cyhalothrin for use in field, vegetable, tree and vine crops. It will be sold as Proaxis and in a higher-concentrated form called Prolex.

Cocodrie, a rice variety released by the LSU AgCenter in the late 1990s, remained king of the rice paddy in Louisiana this year, but AgCenter researchers say they’re tinkering with a number of new rice lines that could give farmers more options at planting time within a couple of years.Among those are new medium-grain experimental lines and improved Clearfield rice lines that soon will be evaluated in winter plots at a Puerto Rican nursery that the LSU AgCenter shares with other universities.
