Varietal Screening for Metribuzin Sensitivity--Univ. of Ark.

The handicap to metribuzin use is the sensitivity of soybean varieties to this herbicide. Other environmental factors, including soil texture, organic matter, rainfall, soil pH and product use rate, may also play a part in sensitivity. The University of Arkansas Division of Agriculture conducted a greenhouse screening of soybean varieties, testing their tolerance to metribuzin. The following document breaks down the metribuzin injury scale. Please note that most varieties show an acceptable tolerance to metribuzin. Farmers are advised to choose a variety with a high level of tolerance.
