What is safe microinjection?
Microinjection into a tree trunk is a new orchard protection technique. The tree plays an active role in the treatment itself, bringing about a fundamental break in the reasoning behind orchard protection.
The injection technique can be considered as an alternative method of applying plant protection products. After having made a hole in the trunk, the plant protection product is introduced directly into the tree's vascular system for redistribution to the target organs. Injection offers undeniable advantages in terms of reducing losses to the environment and protecting the operator. Today, however, the use of this technique remains confined to ornamental trees. Since 2018 in France, the emamectin-based product REVIVE II has been authorised for use against palm weevil and horse chestnut leaf miner (Verpont, 2022).
