The LSU AgCenter is dedicated to providing innovative research, information and education to improve people’s lives. Working in a unique statewide network of parish extension offices, research stations and academic departments, the LSU AgCenter helps Louisiana citizens make the best use of natural resources, protect the environment, enhance agricultural enterprises and develop human and community resources.
Research is focused on insect management and crop response to new and currently registered insecticides, development/ updating of economic thresholds in field crops, quantification and characterization of insecticide resistance by target insects. Identification and documentation of invasive insect species, development of IPM programs in field crops, and investigation of insect resistance management strategies to evade or mitigate insects that could or have developed resistance to insecticides.
The pathology program focuses on applied projects geared towards developing new or refining existing integrated disease management strategies. Commercial and experimental fungicides are evaluated for effectiveness on many foliar and soilborne diseases. Fungicide resistance in important row crop pathogens is identified and monitored while developing mitigation strategies. Breeder selections, varieties, and hybrids are screened annually for naturally-occurring diseases and chloride tolerance. The effect of cultural practices such as crop rotation or tillage type are continually investigated as part of an integrated disease management program. New and emerging diseases are identified and management strategies are developed accordingly. Laboratory and greenhouse facilities at the station allow for diagnosis and basic research on economically important row crop pathogens. Results from this program are used extensively by parish agents, producers, industry, and agricultural consultants to make disease management decisions agronomic crops.
Results from research efforts in conservation tillage have led to widespread utilization of reduced tillage in the area. Other agronomic practices, such as plant population, planting date, row spacing and fertilization, are also evaluated. Optimum fertilization including right source, rate, timing, and placement are very important for profitable crop production and sustain soil fertility and productivity. Fertilizer recommendations based on nutrient concentrations at different soil depths as well as the impact of fertilizer source (liquid vs. granular), application timing (fall vs spring), and placement (banding/injection vs. surface application) on crop yields are routinely evaluated to update nutrient management strategies with recent genetics and technologies. Varieties of most agronomic crops are evaluated at the research station, and strategies are developed for producing multiple crops on a given land area within the same year.
The research basis is to develop weed management strategies for rice, corn, soybean, cotton and grain sorghum. There are four main areas of work: 1) preplant, 2) in-season, 3) post-harvest and 4) fall weed management. Crop and weed response to new and existing herbicides and herbicide resistance management are important components of the research effort.

Agriculture production is crucial to the economy of the Northeast Region and state. Personnel at the Macon Ridge Research Station are dedicated to providing research information important to continuing profitability in agriculture production. Research efforts will continue to focus on evaluating new technologies available in agriculture to determine the potential benefits when utilized in production fields. New crop varieties and pest-control technologies will be a part of these evaluations. Research with crop rotations, tillage, fertilization and management effects on disease, insect, and weed impacts will be conducted. Weed science efforts will continue to focus on resolving known and anticipated weed problems in northeast Louisiana. All research efforts will focus on providing information to sustain long-term agriculture production in an environmentally sound manner.
