Studies and research
Trunk injection therapy was the brainchild of an American chemical engineer who, in the 1940s, had the idea that the technique of intravenous injections for humans could be applied to trees.
History has it that this technique was, in fact, invented by Leonard Da Vinci, who injected the trees in his garden during his absence to protect them from disease.
The technique saw much interest and development up to the 1960s with many in-depth studies being carried out in various American universities.
In the 1990s the technique gained further impetus for the defence of trees against parassitic insects which could not be controlled by other means.

In Italy, the technique was studied/used at the Faculty of Agriculture in Florence (Institute of Pathology) in the 1970s. In 1980 Centro Studi Siapa carried out further studies and the first equipment was introduced. Further instruments were developed and by the mid-1990s drip bags were being used; at the beginning of the new millennium Arbosan's equipment was introduced (www.endoterapia.com, www.arbocap.com) followed by some new American devices in the next year and then, in 2001, Arbocap capsules.
These appliances saw quick growth when Cameraria ohridella, a micro-Lepidoptera from Macedonia, arrived in Italy via Friuli Venezia Giulia (north-eastern Italy). The Observatory of Plant Diseases (in Milan) began studying methods of defence against this Lepidoptera following early defoliation of Horse chestnuts in August, a problem still with us to this day.
Various products and equipment were tested: the trial results from the last few years were presented in May 2004 (the conclusions of which will soon be published).
