== Some hardwood trees drop sap from their leaves. This acts as a herbicide for smaller plants growing in their shade. An oak, at full maturity can drop 50, 000 gallons of this fluid in a years time and cause white spots on plants like squash, zuchinni, tomatos and other plants.

Why shouldn’t leaves overheat?
Leaves overheating would cause water loss, just like how people perspire more in heated temperatures (plants perspire through their closed stomata). Plants already lose over 90% of their water through their leaves, and superheated temperatures would cause dehydration and make the plant lose a lot of the water needed to grow.

A defoliant is a plant-removing or plant-killing agent. Plants can, in general, be called foliage. "De-planting" is removing plants, physically or by killing them. Correction - Foliage= Leaves.
