| Louisiana AgSummary An accounting of the value of agriculture in Louisiana. Agents and specialists of the Louisiana Cooperative Extension Service, as well as other agencies - both private and public - compile this information. It focuses on the animal, forestry, fisheries, plant and wildlife commodities that comprise our vital agricultural industry. This industry continues to contribute significantly to the state's economy with the potential for increased impacts through value-added processing. |
| Louisiana Insect Pest Management Guide This 2013 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 use of beneficial insects to control pest populations. A section on organic gardening also is included. |
| Louisiana's Suggested Chemical Weed Control Guide This 2013 guide includes helpful information on herbicides and weed control with detailed suggestions for aquatics, commercial nursery stock, field crops, forestry, fruit crops, home gardens, lawns and many other Louisiana crops. It includes information on different types of herbicide registrations, as well as information on herbicide labels and restricted uses. Also included are sprayer calibration techniques, suggestions for reducing herbicide drift and a guide to proper spray tip selection. |
| Bacterial Streak and Black Chaff of Wheat Bacterial streak is one of the most common bacterial diseases of cereal crops. The pathogen attacks wheat and other grasses. (PDF format only) |
| Leaf Rust of Wheat Leaf rust, also called brown rust, is caused by the fungus Puccinia triticina. This disease is widespread in Louisiana and is probably the most destructive wheat disease. (PDF format only) |
| Septoria Leaf Blotch of Wheat Septoria spp. are mostly parasitic leaf-spotting fungi that attack and damage more than 100 species of small grains and other grasses. The actual damage to wheat caused by Septoria leaf blotch is difficult to measure under field conditions because more than one organism is nearly always involved in foliar infections. (PDF format only) |
| Downy Mildew of Wheat Downy mildew usually is associated with wheat plants grown in poorly drained areas. (PDF format only) |
| Fusarium Head Blight (Scab) of Wheat The scab fungus causes seedling blight, crown rot, root rot, stem blight and scab or Fusarium head blight in wheat. Damage to wheat from scab varies greatly from year to year and is associated with warm, moist environmental conditions that occur after wheat heads emerge. (PDF format only) |
| Powdery Mildew of Wheat Powdery mildew is not a major problem of wheat in Louisiana. In limited cases, however, the disease can reduce plant vigor, cause lodging and reduce yield, kernel size and test weight. (PDF format only) |

| Stripe Rust 5 Early stripe rust. |
| Stripe Rust 4 Typical stripe rust. |
| Stripe Rust 3 Stripe rust linear pustules. |
| Stripe Rust of Wheat Stripe rust, also called yellow rust, is caused by the fungus Puccinia striiformis. This disease is a common problem in Louisiana during cooler conditions. (PDF format only) |
| Wheat Diseases Information Wheat diseases, wheat disease identification, wheat disease photo galleries, wheat disease articles, and wheat fungicide links information. |
| Stem Rust of Wheat Stem rust, also called black rust, is caused by the fungus Puccinia graminis. Although stem rust is found in Louisiana wheat fields nearly every year, significant damage occurs only to a few isolated, late-maturing fields. (PDF format only) |
| Wheat Diseases Photo Galleries Wheat disease photograph collections to help diagnose and understand wheat diseases found in Louisiana. |

| 2005 Small Grain Performance Trials This page contains the 2005 small grain data report. |
| 2006 Small Grain Performance Trials The 2006 statewide wheat performance trials included 51 varieties and experimental lines. Recommendations are based on the relative performance of an entry for two years within a region. |
| 2007 Small Grain Performance Trials The 2007 statewide wheat performance trials included 51 varieties and experimental lines. Recommendations are based on the relative performance of an entry for two years within a region. |
| 2008 Small Grain Performance Trials Small grain variety trials are conducted annually by scientists of the Louisiana Agricultural Experiment Station (LAES) to evaluate grain yield, agronomic performance, and disease reaction of varieties and advanced lines. The trials are conducted at seven LAES research stations representative of the major soil and climate regions of the state. The 2008 statewide wheat performance trials included 60 varieties and experimental lines. |
| 2009 Small Grain Performance Trials Small grain variety trials are conducted annually by scientists of the Louisiana Agricultural Experiment Station (LAES) to evaluate grain yield, agronomic performance, and disease reaction of varieties and advanced lines. The trials are conducted at seven LAES research stations representative of the major soil and climate regions of the state. The 2009 statewide wheat performance trials included 70 varieties and experimental lines. |
| 2010 Small Grain Performance Trials Small grain variety trials are conducted annually by scientists of the Louisiana Agricultural Experiment Station to evaluate grain yield, agronomic performance and disease reaction of varieties and advanced lines. The trials are conducted at seven LAES research stations representative of the major soil and climate regions of the state. Entries are included in the trials based upon previous performance or at the request of the originating agency. |
| 2011 Small Grain Performance Trials Small grain variety trials are conducted annually by scientists of the Louisiana Agricultural Experiment Station to evaluate grain yield, agronomic performance and disease reaction of varieties and advanced lines. The trials are conducted at seven LAES research stations representative of the major soil and climate regions of the state. Entries are included in the trials based upon previous performance or at the request of the originating agency. |
