The spring 2011 issue of Louisiana Agriculture features the soybean, a crop vital to the state's economy. Topics covered include the latest research on how to grow soybeans successfully in the state. Other articles talk about extracts from soybeans and their uses in boosting the nutritional value of foods. Vol. 54 No.2, 40 pages.

Seedling disease
Sensory tests of a mayonnaise-like product made from soy protein and rice bran oil got high marks from a consumer study in which people were asked to taste and evaluate the product developed by LSU AgCenter researchers.
For crops to grow, essential plant nutrients must be available in sufficient and correct proportions in the soil. Nutrients that crops need in the largest amounts, such as nitrogen, phosphorus and potassium, are the most limiting and often deficient in most crop production systems.
The most yield-limiting and economically important soybean pest across the southern United States is a complex of stink bugs. Historically, the most common species in this complex had been the green stink bug, southern green stink bug and the brown stink bug.
Red crown rot disease
Purple seed stain disease
Progress is being made, but research continues on the redbanded stink bug problem in soybeans across the state of Louisiana.
SHREVEPORT, La. – A Brazilian weevil that feeds on giant salvinia is a biological control for the invasive species that has been taking over water bodies in Louisiana since it was first discovered in the state in the Toledo Bend reservoir in 1999.
LAKE ARTHUR, La. – U.S. rice acreage has fallen significantly, and that could affect prices, according to LSU AgCenter economist Mike Salassi.
Soybeans are plagued by numerous diseases affecting the leaves, stems, pods and roots. Diseases of major concern are Cercospora foliar blight, purple seed stain, aerial blight, soybean rust, pod and stem blight, and anthracnose.

The history of the soybean crop in Louisiana is rather brief compared with cotton, sugarcane, rice and corn, which have been grown in the state for several hundred years.
Epidemiological observations have consistently shown that incidences and mortality rates of cancers, diabetes, multiple sclerosis, Alzheimer’s disease and several chronic degenerative diseases vary significantly across regions of the world.
These articles were published in the spring 2011 issue of Lousiana Agriculture magazine.
Soybean producers annually face diseases, insects and environmental stresses that affect the yield and quality of their crop. The use of varieties with resistance to specific pests and stresses is generally considered the most cost-effective solution to these problems.
Soybean viruses have been shown to cause significant yield losses throughout the soybean-producing areas of the world. In the United States, many different viruses infect soybeans.
These nine photos help illustrate the problems with green plant malady.
In recent years, soybean growers have experienced significant problems with mature plants retaining green leaves, green stems and green pods in soybean fields. The occurrence of these symptoms either alone or together has been termed the “green plant malady,” which is also known as the “green bean” or “green plant” problem.
Soybean is one of the many commodities that comprise the rich mosaic that is Louisiana agriculture.
The Soybean Rust Sentinel Plot Program is designed to monitor the presence and movement of Asian soybean rust in the state.
Soybean rust disease
Louisiana soybean growers have historically tried to protect their crop from a diverse insect pest complex consisting primarily of stink bugs, Lepidopteran defoliators (green cloverworm, soybean looper and velvetbean caterpillar), threecornered alfalfa hopper, and bean leaf beetle. Annually, at least one of these pests causes significant problems and isresponsible for limiting soybean productionby reducing yield.
Charcoal disease
Cercospora disease
Isoflavones are compounds found in soybeans that have powerful antioxidant characteristics and have been shown to prevent cancer and other diseases.
Downy mildew disease
The double-cropping of soybeans and wheat has become an increasingly attractive option economically for Louisiana farmers because of technological improvements, and about 85 percent of Louisiana wheat acres are doublecropping with soybeans.
From its humble beginnings in 1973 as a project between the student government association and the Dairy Science Department, the popularity of the LSU Dairy Store remains strong.
Photos aerial blight disease
Every crop can be damaged by many different diseases and pests throughout its life cycle. In common practice, growers apply pesticides to control different pathogens and insect pests and protect a crop from all possible diseases and pests.
Anthracnose disease
Herbicide resistance is defined by the Weed Science Society of America as the “inherited ability of a weed biotype to survive and reproduce despite exposure to a dose of herbicide that was previously effective on the population.”
Bacteria pustule disease
Cristina Sabliov, working with a team of scientists in the LSU AgCenter’s Department of Biological and Agricultural Engineering, has developed a continuous microwave system that can be used to extract beneficial compounds, such as isoflavone oils, from soy flour.
The Louisiana Soybean Variety Testing Program plays an important role in the soybean industry in Louisiana. LSU AgCenter researchers conduct the trials annually to evaluate commercial soybean varieties for yield potential, agronomic performance and resistance to diseases.
The Louisiana Soybean Research Verification Program allows producers a chance to participate in a program that demonstrates profitability through improved agronomic and cultural practices.In Louisiana, according to the National Agricultural Statistics Service, soybean producers averaged 41 bushels per acre on 1,020,000 acres in 2010.

Louisiana seafood is fast and easy to grill for summertime eating enjoyment because it has smaller percentages of skeletal and connective tissues than equal portions of red meats or poultry.
Harvest aids are herbicides applied to the crop late in the growing season to dessicate leaves and accelerate plant drying. This can result in earlier harvest and improved crop harvest efficiency and seed quality.
Frogeye leaf spot disease
Louisiana farmers often harvest soybeans with a high percentage of damaged seed, resulting in significant marketing discounts. Seed damage is caused by Louisiana’s climatic conditions that encourage high levels of diseases and insect infestations in soybean fields.
