•  In situations where a tree has suffered root loss or root damage, the uptake of nutrients may be restricted or not possible. Root damage or function may be impeded by soil compaction, water logging, construction work, or toxins.
    • In order to provide essential nutrients to a living tree that has reduced root functionality, infusion into the vascular system of the sick tree can allow it to recover and with normal vigour restored, develop new roots, resume a normal life and survive for many more years.
    • Developed by a team led by Dr Lucio Montecchio at De Rebus Plantarum in Italy, which is a department of the University of Padua, BITE (Blade for Infusion in Trees) is a drill-free instrument with a small, perforated (lenticular shaped) blade that enters the trunk by separating the woody fibres with minimal damage.
    • BITE allows the natural uptake of an external liquid up to the leaves, when transpiration rate is highest, during  Spring to late Summer.
    • BITE is a simple, fast, effective and proven method of applying beneficial compounds to trees under stress or in decline, often due to root damage, soil compaction or other stress inducing factors.
    • BITE also ensures that all of the applied treatment goes directly into the tree with no contamination of adjacent targets.


    • In woody plants, sap moves upwards through the xylem vessels due to a decreasing gradient of water potential from the groundwater to the foliage. Mass Flow.
    • Due to these factors and their dynamics, small amounts of sap-compatible liquids (i.e.EnerBite) can be infused into the xylem system, reaching their target from the inside without any external contamination or additional energy use by the tree to uptake the nutrients.
    • Furthermore, the lenticular shaped blade reduces the xylem vessel cross section, increasing sap velocity, which consequently lowers the sap pressure – in fluid dynamics, Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. Consequently the applied sap-compatible liquid is naturally drawn into the tree.
    • BITE is an endotherapic or “trunk infusion” method.
    • Traditional pressure injection techniques utilise drilling methods in order to gain access to the xylem vessels beneath the bark. This drilling causes significant localised damage to the injection area which is slow to heal and can cause damage to the cambium, surrounding tissue and bark.
    • With the BITE lenticular blade, the infusion ports partially close soon after the removal of the blade due to the natural elasticity and turgidity of the plant tissues, and the cambial activity completes the healing process in few weeks.
