Although tumbleweed, or Russian thistle, is rare in well-irrigated soils such as lawns, mowing keeps the summer annual from setting seed. Pre-emergent atrazine kills tumbleweed seeds before germination in spring. Glyphosate and 2,4-D are post-emergent controls on young plants, but 2,4-D must be used only while zoysia grass is dormant.
