Provides a list of plant hosts for Asian Soybean Rust.

Symptoms of soybean rust appear identical regardless if they are caused by Phakopsora pachyrhizi or Phakopsora meibomiae. Host plants infected with soybean rust first exhibit small lesions that gradually increase in size and turn from gray to tan or brown. They become polygonally shaped restricted by leaf veins, and may eventually reach 2 to 3 square millimeters.

Detailed topics include drift of pesticides, hazards of pesticides to beneficial insects and wildlife, phytotoxicity and using beneficial insects to control pest populations. A section on organic gardening also is included.

A bacterial (rust-like) disease on kudzu was found on May 18 in Madison Parish. These pictures should help you identify the differences between this disease and rust. The water-soaked lesions are not usually present in the field, which causes this to look more like rust.

LSU AgCenter scientists are launching a series of research projects in 2005 to learn what they can about Asian soybean rust and how this potentially devastating disease will develop in Louisiana.

2009 recomended controls and thresholds for soybean insect pests. Brief biological sketches of soybean insect pests included. Soybeans can be damaged by insects any time from plant emergence until they get near to the harvest in Louisiana. Many kinds of insects feed on leaves, stems, roots, nodules and pods, but only a few require control with insecticides. (PDF Fomat Only)

Describes the potential impact on soybean profits of late-planted soybeans infested with the Red-Banded Stink Bug.

This report presents estimates of projected production costs for the production of cotton, soybeans, corn, grain sorghum and wheat in Northeast Louisiana for the 2009 crop year.

This report presents estimates of projected production costs for the production of cotton, soybeans, corn, grain sorghum and wheat in the Red River and central areas of Louisiana for the 2009 crop year.

The southern green stink bug, Nezara viridula (L.), and the brown stink bug, Euschistus servus (Say), are common pests in Louisiana agricultural crops including cotton, soybeans, corn and grain sorghum. The objective of this presentation is to point out some visual differences between the two species which are helpful for early field detection.

A brief PowerPoint presentation that shows the locations where the stink bugs have been found and compares indentifying characteristics with other stink bugs.

Asian soybean rust ( Phakopsora pachyrhizi ) was found for the first time in the United States in Louisiana. While doing a routine inspection of a soybean production field at the LSU AgCenter’s Ben Hur Research Farm, Dr. Ray Schneider, plant pathologist, found what he suspected as Asian soybean rust.

In managing soybean rust, the use of “sentinel plots” plays a large role in providing information on the spread of the disease. The objective of sentinel plots is to have a crop in the field well ahead of the traditional crop, thus acting as a “trap” crop for the spores. If rust is detected in the sentinel plots, this will allow proper production decisions on a regional and statewide basis to be made accordingly.

Potential Louisiana Sentinel Plots are indicated by red triangles.

The purpose of this plan is to outline actions for the pre- and post-confirmation of the establishment of Asian soybean rust (Phakopsora pachyrhizi) in the United States and Louisiana.

(Distributed 02/17/09) Asian soybean rust has been found in Louisiana kudzu in Washington, East Baton Rouge, Tangipahoa, Iberia and St. Mary parishes, but weather conditions will be the telling factor for the disease outlook in 2009, according to LSU AgCenter plant pathologist Dr. Boyd Padgett.

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

(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 trouble with Asian soybean rust, the disease most feared by soybean farmers, is that the spores that cause it can blow into a field from anywhere, anytime. And Hurricane Dennis could bring in a new wave from South America.

LSU AgCenter experts are preparing to monitor for Asian soybean rust in Louisiana this year as the fungus threatens to enter the state from a new direction – the west. The rust disease, which is spread by windborne spores, is feared because it’s hard to detect until it’s too late to do anything to stop it.

In Louisiana, southern green stink bugs and brown stink bugs (Figures 1, 2 and 3) have become common pests of corn, cotton, grain sorghum, soybean and wheat. In corn, an infestation can cause injury to the plant from seedling emergence through ear formation and grain development. Seedlings punctured by stink bugs exhibit small holes surrounded by localized dead tissue.
