' Nelson Mining Resource <br /> Integrated Noxious Weed Management Plan <br /> August 2019 <br /> Page 11 <br /> 3.3.2 Common Mullein <br /> ' Cultural — Establishment of selected, aggressive grasses can be an effective cultural control of <br /> mullein. <br /> ' Mechanical—Mowing or chopping is most effective when mullein plants are at the early flower <br /> stage but will have to be repeated throughout the season. Grubbing or digging the plants below the <br /> ' root crown level is effective in the rosette stage. <br /> Chemical/Herbicides—Pending the chemical selected, applications are best done twice per year: <br /> ' once in the spring (late March through May) and again in the(late September or early October). <br /> Biological—There is no recommended Biological control currently. <br /> ' 3.3.3 Field Bindweed <br /> Cultural — Establishment of selected, aggressive grasses can be an effective cultural control of <br /> ' field bindweed. Good grazing management will stimulate grass growth and keep pastures healthy. <br /> Healthy pastures may be more resistant to field bindweed invasion. Bare spots caused by <br /> ' overgrazing are prime habitat for weed infestations. <br /> Mechanical— Cutting, mowing, or pulling has a negligible effect unless the plants are cut below <br /> the surface in the early seedling stage. Well-established populations have a large seed bank in the <br /> ' soil that can remain viable for over 40 years. <br /> Chemical/Herbicides—Pending the chemical selected, applications are best done twice per year: <br /> ' once in the spring (late March through May) and again in the (late September or early October). <br /> Optimum results occur when the plants have recently received moisture and are actively growing. <br /> ' Biological — The bindweed gall mite (Aceria mahlerbae) has proven to be effective in reducing <br /> field bindweed infestations. <br /> 1 <br />
