TRANSCRIPT
Making the proper variety selection is critical to maximize profit potential. Variety selec-tion may be the single most important decision you make. No two farms are alike. There are differences in production practices, soil types and climatic conditions just to name a few. You should plan to plant more than one variety. This will help reduce the risk associated with these conditions and weather. For these reasons, it is important to gather as much data as possible before deciding which varieties to plant.
Begin with data from your area and of similar production conditions, this should include Commercial Variety Trials from Research Stations, Extension demonstrations and/or company trials. If you are unable to find information that matches your production, look for varieties that consistently outperform others when averaged across locations. A proven variety is one that performs well in a wide range of conditions, soil types, and locations.
LOUISIANA – “SELECTS”
Louisiana – “Selects” is a listing of top performing varieties in Louisiana. It was based on Commercial Variety Trials and Extension Demonstrations.

Soybean Insect Survey
Dr. Rogers Leonards would like for you to complete the following survey. Three years ago many of you were participated in a multi–state survey related to soybean insects. Producers in Arkansas, Louisiana, and Texas provided important information on their approaches to soybean insect con-
trol. This follow-up survey only takes a few minutes to complete and will provide valuable informa-tion to researchers working on soybean insect control.

Please take a few minutes to complete this
important soybean insect survey.
February 3-4th, 2011
Louisiana Ag Industries Association (LAIA) An-nual Convention, Paragon Casino & Resort, Marksville, LA. Members and representatives from the seed, fertilizer, chemical, grain, and feed industries are invited to attend this annual meet-ing which will be held at the Paragon Casino Re-sort in Marksville. This meeting is open to any and all producers, consultants, industry repre-sentatives, and LSU AgCenter personnel. For more information, please contact Donna Morgan at 318.229.9955 or [email protected]

Metribuzin is a soil residual herbicide that provides excel-lent control of a number of problem annual grasses and broadleaf weeds in soybean. Metribuzin containing herbi-cides, such as Authority MTZ and Boundary, offer the benefit of increased spectrum of weeds controlled over that observed with metribuzin (Sencor) applied alone. Selecting a rate to provide acceptable weed control can be influ-enced by soil type. LSU AgCenter recommendations sug-gests applying metribuzin alone at 0.25 to 0.38 lb/A on light soils where organic matter is 2% or greater, 0.3 to 0.67 lb/A on medium soils, and 0.67 to 1.0 lb/A on heavy soils. Al-though labels for herbicides containing metribuzin typically list soybean varieties that are sensitive to the herbicide, they do not always list varieties that are commonly used in Louisiana.
Although realizing the benefits from a weed control stand-point, past experience with metribuzin injury potential to soybean has caused producers to be hesitant in considera-tion of the herbicide in at planting weed management pro-grams. Therefore, research was conducted in 2010 at the Dean Lee Research and Extension Center in Alexandria and the Northeast Research Station in St. Joseph to screen eight soybean maturity (MG) IV and V varieties for toler-ance to metribuzin. Varieties were selected in consultation with LSU AgCenter Extension Soybean Specialist and upon review of the “Louisiana Selects” soybean variety list published in 2009. Each variety was seeded at 130,000 seeds/acre on May 25, 2010 at both locations.
Metribuzin 75 DF was applied preemergence at 6 oz per acre, which corresponds to 0.28 pounds active ingredient
per acre. For herbicides that contain metribuzin plus an-other herbicides (i.e. Authority MTZ, Boundary), the labeled rate of the product typically contains 4 oz per acre of metribuzin or less; therefore, utilizing the 6 oz rate allowed for accurate screening of tolerance. Below are tables that provide soybean phytotoxicity ratings (0 = no soybean in-jury; 100 = complete soybean death) 8 and 15 days after application (DAA), treated and nontreated soybean yield, percent yield reduction, and ranking of soybean variety tol-erance. The ranking of soybean variety tolerance is pri-marily based upon yield reduction.
Varietal response to metribuzin was observed only at Alex-andria. The primary difference between experimental loca-tions was amount of rainfall received after herbicide appli-cation. In the 15 d interval between planting and the 15 DAA rating, 5-inches of rainfall was recorded at Alexandria compared to only 1-inch at the St. Joseph location. This difference may have played a major role in greater re-sponse observed at Alexandria. Additionally, it should be noted that greater injury was noted for some varieties, but little to no yield reduction was observed. If a soybean vari-ety found to have excellent or good-fair tolerance to metribuzin is planted and metribuzin is applied, then early-season soybean injury may be observed. However, the opposite is also true. In that situation, it may be best to either avoid the use of metribuzin or plant a variety found to be tolerant to metribuzin. Although only representing one year of data, information can be utilized on decisions con-cerning potential variety problems with metribuzin, espe-cially considering that many soybean varieties share a common lineage.
