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.

Performance of grain sorghum hybrids is annually evaluated by Louisiana Agricultural Experiment Station (LAES) researchers. The purpose of these trials is to provide Louisiana growers, seedsmen, county agents of the LCES, and other interested individuals and organizations with unbiased performance data for commercial grain sorghum hybrids submitted for evaluation by private agencies. Results from these trials are used by the LCES for recommending hybrids.

2009 recommendations. This information will help producers choose grain sorghum hybrids which have displayed good yield potential and agronomic performance. The LSU AgCenter conducts yearly grain sorghum hybrid yield tests at several locations in Louisiana. This is done to provide producers with unbiased information on hybrid performance under different soil types and climatic conditions.

This 2008 guide was compiled by LSU AgCenter experts and includes regulations, precautions and suggestions for pest control in Louisiana. 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.

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.

This guide for 2008 contains suggestions for management of the most important or more prevalent diseases of Louisiana plants. It includes information on fungicides, bactericides and nematicides, as well as safety precautions for using them.

This article examines the impact on profits of planting grain sorghum late. Late planting generally occurs when grain sorghum follows winter wheat. Grain sorghum planted beyond the optimum planting window has lower yields and increased insect pressure. These two factors combine to drastically reduce the profit potential compared to grain sorghum planted in the optimal planting window.

Louisiana farmers and forest producers could find a silver lining in the cloud of rising fuel prices – with the development of new fuels from crops they already grow or could grow.

The chinch bug is commonly found in all areas of Louisiana feeding on a variety of grass crops and wild grasses. In some years it is an economic pest on corn and grain sorghum, especially if high populations migrate into these crops in the early spring when plants are young. To prevent stand loss and yield reductions, it is important to understand the biology and behavior of this pest as it relates to corn and grain sorghum.

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.
