On poles with 18 inches circumference, how is MITC Fume usage described?

• A. It must be avoided
• B. It is optional
• C. It may be used
• D. It must be used

Answer: (C)

For this size of pole, using MITC fumigation is an option, not a requirement. That means you may choose to apply MITC if the situation calls for it—for example, if there’s a pest risk or specific management plan—but you’re not mandated to fumigate every pole of this circumference. When you decide to use it, follow the label directions and safety rules, including proper application methods and protective measures. The other statements aren’t correct because MITC fumigation isn’t banned for these poles, nor is it mandatory in all cases; it’s allowed as one of the possible approaches.
