Trunk injection of trees is a way to treat many different insect and disease problems, as well as nutrient deficiencies, in an efficient and environmentally friendly way. The used active ingredient is Azadirachtin and it has been compared with the only water injection. The functionality of these treatments has been tested to find out the best method and its effective utility in practice activities. 54 young Nettle tree (Celtis australis L.) has been testes with three instruments - Arboprof ®, Arbocap ® e Arborjet ®- different for the injection pressure. These treatments were done using both active ingredient and water with a organic colouring. The trees were knocked down after 2-5-72/96 hours after the injection. Stems were cut until the colour was visible, and the length of the translocation profile was measured. This preliminary work suggest some changes in the next experiments, such using adult trees and increasing the knock down time. The average of the length values explain that the best method of trunk injection is Arborjet.

Abstract

Trunk injection of trees is a way to treat many different insect and disease problems, as well as nutrient deficiencies, in an efficient and environmentally friendly way. The used active ingredient is Azadirachtin and it has been compared with the only water injection. The functionality of these treatments has been tested to find out the best method and its effective utility in practice activities. 54 young Nettle tree (Celtis australis L.) has been testes with three instruments - Arboprof ®, Arbocap ® e Arborjet ®- different for the injection pressure. These treatments were done using both active ingredient and water with a organic colouring. The trees were knocked down after 2-5-72/96 hours after the injection. Stems were cut until the colour was visible, and the length of the translocation profile was measured. This preliminary work suggest some changes in the next experiments, such using adult trees and increasing the knock down time. The average of the length values explain that the best method of trunk injection is Arborjet.
