Yellow Starthistle, 50-75% Tree Cover. This high tree cover does not provide a niche for weeds. Tree cover will be patchy to dense stands of trees. Please select the Landscape Position that best represents your patch.
Yellow Starthistle, >75% Tree Cover. This high tree cover does not support a niche for weeeds. Tree cover will be very dense trees. Please select the Landscape Position that best represents your patch.
The patch is located on a flat part of the landscape, with little to scattered trees. This provides you the most management options available to control Yellow Starthistle since there are no restrictions due to the site characteristics.
Your Yellow Starthistle patch is located on a hillside. The slope of the hill with 0-25% tree cover will slightly limit the control options that would be feasible for the patch. Please select one of the Management Options below that are feasible for your patch.
Prescribed Burning (338): This is a highly specialized practice that requires intensive training and sufficient support personnel and equipment. A safe successful burn must be timed for proper humidity, wind conditions, air temperature, and fuel conditions (ignitable vegetation).
Mechanical: Mowing can be completed with a tractor, lawn mower, or weedeater. Timing of mowing will lead to success. Pasture considered for mowing should not have many rocks to prevent possible fire. Timing of mowing and growth form of YST are important to a successful mowing program.
Grazing (528). Prescribed grazing may be applied on all lands where grazing and/or browsing animals are managed. A prescribed grazing schedule is prepared for all fields and pastures to be grazed.
Biological: This practice uses natural enemies, biological control agents, to attack and control the targeted weed. Biological control methods do not eradicate; rather they provide sustained suppression of the target weed populations.
Chemical control tends to be the first control option most people utilize. There are many chemicals available that selectively control Yellow Starthistle. The table to the right is taken from Yellow Starthistle Management Guide.
Revegetation: Either attempting to re-introduce or introduce desired species can help out compete invasive weeds. Revegetation is not always as successful as other methods but can provide an important aspect of weed control.
