Which term describes an application made after the crop or weeds have emerged?

• A. Postemergence
• B. Preemergence
• C. Preplant
• D. Stomach poisons

Answer: (A)

Postemergence refers to applying a pesticide after the crop or weeds have emerged above the soil surface. This timing targets plants that are already growing, as opposed to preemergence, which is applied before emergence to prevent germination or early growth. Other terms like preplant mean application before planting, and stomach poisons describe a mode of action (toxicity requiring ingestion) rather than when the product is applied. So, because the question asks for the timing after emergence, the correct concept is postemergence.
