i) Chemical controlTo spray, or not to spray?• Does the “good” outweigh the “bad”?

How effective is herbicide against targets?Will herbicide affect non-targets?Will herbicide use conflict with other management goals/uses?Will there be adverse environmental impacts?Is it cost effective?

i) Chemical controlTo spray, or not to spray?• Does the “good” outweigh the “bad”?• Can the herbicide be practically and safely used?

Have you read and understood the label?What are the safety protocols for storing, mixing, transporting,

using, disposing of herbicide?What are federal, state, & local regulations for use of herbicide?Is specific or general applicator training or permits required?Is the appropriate protective gear available and practical to use?

Based on chemical structure• Mode of action

Similar chemical structure usually similar modes of action, but different structure can also give similar modes of action
