Which chemical is used to control plantain?

• A. Endothal is used
• B. 2,4-D is used
• C. Glyphosate is used
• D. Atrazine is used

Answer: (B)

Plantain is a broadleaf weed, so the herbicide chosen should target broadleaf plants without harming grasses. 2,4-D is a synthetic auxin herbicide that is readily absorbed through the leaves of broadleaf weeds and translocated to growing points, causing uncontrolled growth and eventual death in dicots like plantain. Grasses tolerate typical lawn-use rates, so using 2,4-D reduces plantain while sparing the turf. Other options would either be non-selective (killing both grasses and broadleaf plants) or are used in different contexts (such as crops or aquatic settings), making them less suitable for lawn weed control.
