Disclosed herein are compositions including a dispersion of solid particles of a substantially insoluble copper compound, and an organic biocide, wherein at least 20% of all particles of the composition have a particle size greater than 25 microns. Also disclosed herein are methods of making and using the same.

A method for treating a ground-line area of wooden posts in use, that consists of burying a tank of treatment product in the ground next to the post, with a mechanism that automatically injects a certain quantity of said treatment product into the post, once per year. The driving agent allowing said injection can be a pressure generated within the device itself by various means, or electric current originating from a photovoltaic panel or a battery. The technique is non-invasive for the post, and offers the opportunity to choose a tank of required size, and the quantity of treatment product to be automatically injected into the post once per year. The technique is of particular interest for posts installed in built-up areas, because most existing techniques require the pavement to be broken so that the base of the post be exposed to be treated, and then rebuilt after treatment.

The present injection apparatus is designed for replenishing embedded foundation preservation wraps with preservative whilst avoiding spillage. The injection apparatus comprises an injection bayonet having a lumen fluidly interfacing a plurality of preservative outlet nozzles along the injection bayonet and a preservative inlet fluidly interfacing the lumen. A portable preservative containing tank may be attached to the inlet via a flexible hose. The apparatus further comprises a syringe operating between the preservative inlet and the lumen. When replenishing the preservation wrap, the injection bayonet is inserted between the preservation wrap and the foundation so that preservative is configured to be supplied via the preservative inlet to flow out from the nozzles via the lumen to replenish the preservation wrap with the preservative. After replenishment, the lumen is purged of residual preservative using the syringe.
