The importance of guttation for plants can be identified by the fact that it might serve as a pressure-release valve in precipitation and continuous absorption of water, with resultant progressive development of hydrostatic pressure that pumps water up in the leaves (Eaton 1941). Some vascular plants, including grasses, have a phenomenon known as guttation, which is the exudation of droplets of xylem sap on the tips or margins of their leaves. minerals & metals like potassium, calcium, manganese, iron and salt (sodium), viruses, bacteria, fungi (dormant and active), depending on the host plant, microscopic cell debris from nearby wounds on the plant, proteins and compounds the plant uses to defend itself (antibacterial and antiviral), toxins and contaminants the plant seeks to expel, In extreme cases, entire bee colonies can die off.
