Preemergence weed control involves applying chemicals to the soil to stop the germination or growth of what?

• A. Weed seeds
• B. Established weeds
• C. Soil pathogens
• D. Insects

Answer: (A)

Preemergence weed control targets weed seeds. By applying herbicides to the soil before germination, the product stays in the upper soil layer and becomes active with moisture, creating a barrier that prevents seeds from germinating or seedlings from emerging. It won’t affect weeds that are already growing (established weeds), and it isn’t aimed at soil pathogens or insects, which require fungicides or insecticides.
