Preplant treatments refer to which of the following?

• A. Treatments made after crop emergence.
• B. Treatments made to soil before a crop is planted.
• C. Treatments for seeds only.
• D. Treatment to leaves of crop.

Answer: (B)

Preplant treatments refer to applying materials to the soil before a crop is planted. This targets soil conditions and soil-borne pests to protect germination and early growth, helping establish the crop more reliably. This is different from treatments after the crop has emerged (postemergence), treatments applied to seeds before planting (seed treatments), or treatments applied to the leaves (foliar or leaf applications). The option describing treatment to soil before planting best fits, since it focuses on the soil and timing before the crop is sown.
