How are ornamentals treated in this spray method?

• A. Dilute sprays applied to runoff.
• B. Concentrated sprays applied to foliage.
• C. Granular formulations applied to soil.
• D. Foam emulsions sprayed at high volume.

Answer: (A)

The key idea is that ornamentals are treated with a dilute spray and applied until runoff. This approach wets the plant thoroughly, reaching irregular shapes and hard-to-reach surfaces without delivering a high concentration that could cause leaf burn or other phytotoxicity. By using a dilution and applying to runoff, the product covers both the upper and lower surfaces as the spray runs off, helping to distribute the pesticide evenly over the whole plant. The other options don’t fit this method: concentrated sprays on foliage can scorch sensitive ornamentals, granular formulations are not sprays at all, and foam emulsions sprayed at high volume isn’t the standard method for treating ornamentals in this practice.
