Answer:

B. Fewer pesticides are needed because of parasitoids.

Explanation:

Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation.  Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.
