SAVE YOUR TREES and other plants like oak trees, pines, all trees with agrifos mixed with pentrabark .  The agrifos pentrabark mixture should be sprayed on the lower 8 feet of the tree and then soaks into the sapstream of the tree automatically.  This product stimulates the tree to begin the process of producing new roots, leaves and regenerating tissue damaged by environmental stresses of all kinds.  Product is labelled for sudden oak death, beech decline and other tree ailments.  Very low toxicity and environmentally friendly product.  You get 1-2.5 gallon agrifos and 1 quart of pentrabark. Or you can now order 2x2.5gal with 1 qt pentrabark. Mix 1 gallon water with 1 gallon agrifos with 4 fl oz pentrabark and mix well in standard backpack sprayer.   Should treat about 15-20 average size trees.  Caution:  Avoid getting mixture on foliage - only spray bark of tree!!!!  Repeat this treatment often for best results.

Arborfos is an injectable capsule filled with agrifos. It can be directly injected into trees suffering from sudden oak death, or trees at high risk for sudden oak death infections. Install capsules every 6" around the base of the tree using a portable drill and rubber hammer. Very safe and effective way to get agrifos potassium phosphite into trees in order to stimulate the immune system of the tree.

The aim of tree injection is to utilise the trees natural transport system to distribute pesticides, fungicides and fertilizers to the areas where they are most effective without releasing any of these chemicals in the environment. In addition compounds can be injected which boosts the trees own defense mechanism.

The Chemjet® Injector is a spring-loaded device, with a 20mm tapered `nozzle' to assist when placing the injector into the tree. Like a syringe the chemical is `drawn' into the `chamber' of the injector in measured 10, 15 or 20ml quantities. The injector is then `locked off' by turning the handle in a clockwise direction. 

The injectors are placed in the tree by drilling a 4.2mm or 11/64" (wood dependent) hole 50mm deep then utilising the tapered nozzle to secure the injector firmly in place. Turning the handle anti clockwise will then release the device and inject the tree with the desired amount of chemical.

A tree's circulatory system can be likened to that of a human. The tree takes up carbon dioxide and energy from the sun through the leaves where it photosynthesis' it's food. The food (sugars and carbohydrates) then dissolve in the sap and are carried downwards through the inner bark. This food is then distributed to every living cell in the tree including the root system. Applying chemicals to the plant tissue by spraying is inefficient especially in the fight against root pathogens.
