For a pole with 15 inches circumference, MITC Fume usage should:

• A. It should be applied at full rate
• B. It should be applied at reduced rate
• C. It should not be applied
• D. It should be applied only with HHCB

Answer: (C)

MITC Fume is a fumigant that must be used only on targets and sizes allowed by its label. A pole with 15 inches circumference is too small for this product to be applied safely and effectively, so the label instructs not to use it. In such a cases, there isn’t enough wood mass and enclosure to contain and distribute the gas properly, which can lead to unsafe exposure and poor control of pests. So the correct approach is not to apply MITC Fume to that pole size.

Full rate, reduced rate, or using it only with HHCB aren’t appropriate here because the limitation comes from the product label on target size, not from how much product you’d mix or insist on a fragrance additive.
