The Commissioner, or his authorized representative, shall have authority, as provided in this section, to enter cotton fields and other premises in order to carry out such activities, including but not limited to treatment with pesticides, monitoring, and destruction of growing cotton and/or other host plants, as may be necessary to carry out the provisions of this Article. The Commissioner, or his authorized representative, shall have authority to make inspection of any fields or premises in this State and any property located therein or thereon for the purpose of determining whether such property is infested with the boll weevil. Such inspection and other activities may be conducted at any hour with the permission of the owner or person in charge. If permission is denied the Commissioner or his authorized representative, such inspection and other activities may be conducted without a warrant with respect to any outdoor premises, if conducted in a reasonable manner between the hours of sunrise and sunset.
