An applicator is responsible for any damage to private or public property resulting from careless application or misuse of herbicides What are roadside management objectives? The current goal of many roadside management programs is to 1) control only those plants listed as noxious weeds or 2) plants that interfere with the vision of motorists, 3) inhibit the flow of water through drainage ditches, 4) pose a fire hazard, or 5) interfere with activities of humans in other manners. Spot treatments of problem areas, rather than broadcast applications, are commonly used along roadsides. What management techniques do counties use to maintain prairie vegetation on roadsides? Counties integrate several different management techniques to maintain a strong, healthy plant community. Techniques include 1) spot spraying perennial weeds, 2) mowing of annual & biennial weeds to control seed production, and 3) periodic burning to recycle nutrients & increase plant diversity.

What are the most commonly used herbicides for roadside use? The most commonly used herbicides for roadsides are postemergence chemicals that selectively control herbaceous, broadleaf plants without injuring grasses What types of herbicides are registered for use in rights-of-way? The majority of these products are either growth regulator herbicides or ALS-inhibiting herbicides. These herbicides are classified according to their mode of action, or how they kill plants. List some common growth regulator herbicides Growth regulator herbicides include the 1) phenoxy products (2,4-D; 2,4-DP; and MCPP), 2) dicamba (Banvel), 3) triclopyr (Garlon), 4) picloram (Tordon) and 5) clopyralid (Stinger). To broaden the spectrum of control, these herbicides are often tank-mixed or formulated as products that contain more than one active ingredient (e.g., Crossbow is a combination of 2,4-D and triclopyr. The specific combination used should be based on weeds present, rather than indiscriminately adding herbicides to the spray tank. What are some characteristics of growth regulator herbicides? Most of these herbicides are rapidly degraded in the soil; thus, they provide little residual control. Only weeds that are established at the time of application will be controlled. All of the growth regulator herbicides are translocated within the plant, making them effective for both annual & perennial weeds.
