Ynject technology is an innovative mehod to for intravascular administration of active substances, such as fertilizers, biostimulants, and phytosanitary products, to trees and palms. It involves creating small openings in the trunk to facilitate the targeted delivery of these substances. This innovative approach serves a variety of purposes, including pest and disease control in trees and palms, as well as revitalizing the overall health of the tree in cases of nutrient deficiency, water stress, transplant-related issues, and more.
Ynject technology has three fundamental elements:

• High volume, low pressure pressurized device. The liquid inside Ynject is contained by an elastic capsule, which pressurizes the liquid. Both pressure and volume are variable, depending on the need.

• Self-sealing valve: In addition to being able to contain fertilizers/biostimulants, phytosanitary products can also be introduced, using a dosing syringe (watch video), through a self-sealing valve, which will also serve to release the liquid inside the tree. Remember: Ynject does not contain standard phytosanitary products.

• Connector: a plastic element in the shape of an “L” that connects the device and the trunk of the tree or palm tree. There are three types, leafy, coniferous and palm.

The process is as easy as making a hole in the trunk taking care not to cauterize the vascular tissue (watch video), inserting the connector into the hole (watch video) and attaching the device to the connector (watch video). The tree takes care of the rest, absorbing the liquid at its own pace and distributing it evenly throughout its tissues via the vascular system.

Furthermore, if it is used correctly, it can be reused an average of 3-4 times, always after reconditioning under our quality standards. It will be necessary that:

• If you use phytosanitary products, as long as they are recommended by Fertinyect.

• Remove the device as soon as possible after its absorption, to avoid its degradation or the entry of exudates into the device.

• Separate the connector from the device once used, to preserve the valve.

Ynject is very versatile and generally allows you to mix both products, as long as they are among those tested and recommended by Fertinyect.

• A drill, equipped with a 5mm (MINI connector) 6-6.5mm (standard connector) or 6mm special palm tree (palm connector) HSS metal drill bit. It is essential that it be a metal drill.

• A rubber or nylon hammer to drive the connector into the tree.

• Ynject devices and suitable connectors.

Without counting the bark or remains of tabalas, in palm trees, the trunk perimeter (circumference) will be measured at the height of our chest. From this measurement, the number of devices to be applied is calculated.

• Hardwoods: 1 ynject / 20-30 cm perimeter.

• Pines and resinous species: 1 ynject / 25-35 cm of perimeter.

• Palm trees: 1 ynject / 30-40cm perimeter.

We will choose a smaller spacing between devices (larger number/tree) for trees with very large canopies or tall trunks, and the larger spacing (smaller number Ynject/tree) for trees with standard-sized canopies or height.

The application height will depend on whether the insect or disease affects the crown, trunk or root.

• Pathologies of the crown: Treat 1-1.5m from the withers, so that the product is distributed evenly on the trunk when ascending. If the withers are too low, we will have to treat each arm as a separate tree.

• Pathologies of the trunk: At the base of the trunk, so that it infects the entire trunk with the active material.: A la base del tronco, para que infecte todo el tronco con la materia activa.

You can watch a video here. Perpendicular to the trunk, or slightly inclined, 2-3 quick and precise incursions are usually enough, if the drill is suitable, so that the friction between the drill bit and the vascular tissue is minimal, and cauterization is not achieved.

It will deepen 3-5cm in hardwoods and conifers (not counting the bark), and in palm trees a minimum of 1/3 of the radius, up to a maximum of the full radius.

It is important that the area where we inject shows good health, that is, that it does not have very close wounds (a few centimeters in any direction, right/left-up/down). The greater the vascular flow, the better the absorption.

The holes are not reusable in hardwoods and conifers, since a new, non-functional tissue at the vascular level is generated. In palm trees we can reuse them, going deeper and deeper in successive applications, until we reach the center of the stipe.

Trees with very small diameters can be drilled, but, as a guide, from 5cm in diameter it will be viable for any user to apply ynject devices. In these cases, the depth of the holes will be that which allows us to reach the center of the trunk.

The thick end of the connector is inserted into the trunk, leaving the thin end pointing downwards, where we will connect the Ynject device, pressing and screwing (watch video). It should be introduced as little as possible inside the trunk, while we ensure complete sealing. (watch video) to avoid liquid leaks.

In general, in a tree with active vascular flow, absorption is usually very rapid, and the devices can be removed minutes or a few hours later. You will notice that it is absorbed because, although in the filled device you can touch a capsule of liquid (a ball), in the empty device you can only feel a tube.

It is advisable to remove it as soon as possible, to be able to reuse it more safely.

In resinous plants or with defensive exudates, it is essential to remove the devices as soon as possible, so that the resin does not enter inside, which would render it useless and prevent subsequent reuse.

If the tree has a deficient vascular system, it is sick, the weather conditions are not suitable, etc. absorption may be prolonged. It will also slow down if we have injected into knots or in areas adjacent to wounds.

Ynject is used to treat any pest that feeds on tissues that are in contact with the raw sap, that is, the leaves and the living wood of the trunk. Ynject cannot be used to kill pests that feed on dead wood or directly on the fruit, since these tissues are not in contact with the raw sap.
