Which chemical is used to control plantain?

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

Answer: (C)

2,4-D is a selective herbicide used to control broadleaf weeds in turfgrass. Plantain is a common broadleaf weed in lawns, and 2,4-D targets these types of plants by acting as a synthetic auxin, which disrupts normal growth and leads to the weed’s death while grasses tolerate the product at labeled rates. That makes it the best fit for removing plantain without harming the desired lawn grass.

Endothal is mainly for aquatic weed control, not suitable for lawns. Atrazine is primarily used on crops and is not the typical choice for turf management. Glyphosate is non-selective and would kill most plants, including the lawn itself, so it’s not appropriate for controlling plantain in a lawn setting.
