Fumigants are a type of chemical used to produce gas, vapors, or fumes in order to sterilize or disinfect an area. This process requires special licensing to ensure the safe handling and usage of the substance. The other options, herbicides, insecticides, and fungicides, are commonly used to kill or control specific types of plants, insects, or fungi and do not produce gas, vapors, or fumes in the same manner as fumigants. Therefore, these options would not require special licensing to handle.
