Factors Influencing Metham Efficacy on Yellow Nutsedge (Cyperus Esculentus) Tubers

Ransom, C. V., Rice, C. A., and Ishida, J. K. Weed Science 56:856-859. 2008.

Yellow nutsedge infests a large number of hectares in the Treasure Valley of eastern Oregon and western Idaho. Much of its continued expansion appears to be related to onion production in the valley. Fall applications of metham often produce inconsistent results when used to control yellow nutsedge before planting an onion crop. Trials were conducted in the laboratory to determine the influence on yellow nutsedge control of metham dose, duration of exposure, temperature during exposure, and tuber conditioning by washing and chilling at 3 C. All factors influenced metham efficacy against yellow nutsedge tubers.
