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? -
CORRECT ANSWERS ✔✔The most commonly used herbicides for
roadsides are postemergence chemicals that selectively control
herbaceous, broadleaf plants without injuring grasses

List some common growth regulator herbicides - CORRECT
ANSWERS ✔✔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.
