A soybean verification program was initiated in 1994 to verify research by the LSU AgCenter at the farm level. Fields are selected statewide, including various cropping systems, and are monitored weekly. Data are collected throughout the growing season, and cooperators follow LSU AgCenter recommendations until harvest. Historically, LSRVP fields outyield the statewide average by 12 bushels per acre.

More images to help with the identification of Asian soybean rust

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.

(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.

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.
