Abstract

The decline in the natural soil population of seeds of wild mustard [Brassica kaber (DC.) L.C. Wheeler var. pinnatifida (Stokes) L.C. Wheeler ♯ SINAR] under nine cultural and chemical practice treatments was studied under field conditions. Wild mustard plants were not allowed to produce seeds in any treatment. After seven growing seasons, treatments in which the soil was not disturbed (continuous grass sod or continuous chemical fallow) had approximately 50% of the original population of wild mustard seeds remaining. In contrast, less than 3% of the original population of wild mustard seeds remained in a treatment that involved plowing three times a year with additional tillage throughout the growing season. This 3%, however, was equivalent to 2.4 million seeds/ha in the plow layer. Eradication of wild mustard from an infested field may be impractical with currently available techniques.
