Post-emergence treatment is applied when?

• A. Only on leaves.
• B. After the crop or weeds have germinated.
• C. Before planting.
• D. Before germination.

Answer: (B)

Post-emergence treatment is applied after the crop or weeds have emerged from the soil. This timing means you spray once the plants are visible above ground and actively growing, allowing the herbicide to be taken up by the foliage or other exposed tissues. It contrasts with pre-emergence or pre-plant applications, which are made before germination or planting. So the correct understanding is that the treatment occurs after emergence, when there are live plants to target.
