Question

Explanation:

Herbicides are chemical substances. Chemical weed control specifically uses such chemicals (herbicides) to either kill weed plants or prevent their seeds from germinating. Mechanical weed control involves physical methods like tilling or cutting. Cultural weed control focuses on practices like crop rotation. Biological weed control uses living organisms (e.g., insects that feed on weeds). Since the question mentions herbicides (chemicals), it aligns with chemical weed control.

Answer:

chemical weed control
