Sec. 2308. Unlawful devices and methods.

(a) General rule. - Except as otherwise provided in this title, it is unlawful for any person to hunt or aid, abet, assist or conspire to hunt any game or wildlife through the use of:

(8) Any artificial or natural bait, hay, grain, fruit, nut, salt, chemical, mineral or other food as an enticement for game or wildlife, regardless of kind and quantity, or take advantage of any such area or food or bait prior to 30 days after the removal of such material and its residue.
Nothing contained in this subsection shall pertain to normal or accepted farming, habitat management practices, oil and gas drilling, mining, forest management activities or other legitimate commercial or industrial practices. Upon discovery of such baited areas, whether prosecution is contemplated or not, the commission may cause a reasonable area surrounding the enticement to be posted against hunting or taking game or wildlife. The posters shall remain for 30 days after complete removal of the bait.

Then is it also illegal to hunt over a single apple tree, oaks, hickorys, hay fields not being farmed, wheat etc?
I am assuming that a food plot is considered habitat management practices.
