Seedling weeds are easier to control because:

Seedling weeds are easier to control because:

• A. Wax and cuticle are less thick; there are generally fewer and shorter hairs; and they are smaller in size.
• B. They germinate later in the season.
• C. They have thicker cuticles and more hairs.
• D. They grow taller quickly.

Answer: (A)

Seedling weeds are easier to control because their tissues aren’t fully developed yet, so protective barriers are weaker. The waxy cuticle is thinner and there are fewer and shorter hairs, which makes it easier for herbicides to penetrate and be absorbed. They’re also smaller, so a given amount of control product covers more of the plant and its overall biomass is lower, meaning less material is needed to kill it. In short, the combination of a thinner cuticle, less hair, and smaller size reduces both chemical and mechanical obstacles, making seedling weeds more susceptible to control measures.
