Dichlorprop (Weedone 2,4-DP) is characterized as which type of herbicide?

• A. Broadleaf selective
• B. Non-selective
• C. Grass control
• D. Systemic insecticide

Answer: (A)

This herbicide is a plant growth regulator that mimics natural plant hormones, causing overstimulation of growth in susceptible plants. Dichlorprop is absorbed through leaves (and can move within the plant) and disrupts growth patterns in broadleaf weeds. The effect is much more damaging to dicots (broadleaf plants) than to grasses, so it kills broadleaf weeds while leaving grasses relatively unharmed. That behavior is what defines it as broadleaf selective. It’s not a non-selective herbicide (which would kill many plants indiscriminately) and it’s not an insecticide.
