Field bindweed (Convolvulus arvensis) is a tough perennial weed that causes problems for agriculture producers of all sizes, acreage owners, and homeowners alike. The 2, 4-D suppresses the pasture sage, while the fertilizer promotes the recovery of the forage species. Remember that in crop applications of glyphosate will kill the forage plants. Managing for a competitive forage stand should help reduce the spread of this weed. Pre-harvest glyphosate is useful to control dandelion when terminating forage stands. Thick, well-maintained lawn grass will compete well with field bindweed, however, typical pasture settings do not have the dense cover required to deter bindweed. Pastor Trio is also approved as a post-emergent spray in maize. Control of field bindweed used to depend primarily upon intensive tillage and crop rotation.
