The term wood preservatives defines that the wood preservation is the process of preserving wood from the wood destroying agents like insects or fungus so that the life span of the wood can be extended.

It refers to the treatment of wood with chemicals to impart resistance to degradation and deterioration by living organisms. The proper application of chemical preservatives can protect wood from decay, and stain fungi, insects and marine borers, thus prolonging the service life of wood for many years.

The wood contents celluloses, hemicelluloses, starches and other susceptible materials that attract the fungi and insects to be degraded and eaten. After the preservative treatments, the fungi and insects cannot decompose and feed on these substances, hence the durability of wood is to be increased.

Everybody is well aware that wood is prone to attacks by insects and enviromental factors such as moist,midew,decay etc.This is a fact and no need to discuss more about it.

Everybody is also well aware that use of finest quality wood preservative increases the life and structural strength of wood greatly.

One thing must be remembered that wood preservative must contain sporicide, fungicide,termicide and miticide. Must be enviromental freindly and safe to human and cattles and birds. Also one has to offer many formulations according to specific species of wood/timber.

Wood Enemies

Termites

Queen lives in ground up to 20 feet deep.  Workers tunnel to surface under a piece of wood and start eating it.

If they can't reach wood from ground, they build tubes of dirt up to the wood.  Some tubes are self-supporting and reach up to 2 feet.  Others are attached to other structure such as block wall and have been known to go up 8 feet to reach wood.

Termites never work in the open.  Always in wood or tubes.

There are only two types of homes in the world  those with termites and those that are going to get termites.

Powder Post Beetles

Wood Borers is the great enemy of wood and generates great damage to wood.Wood Borer adults are 3/4 inch in size, long horned brown to black in colour.Beetles larave is whitish and produce tunnels in wood.larave stage is more destructive.Borers feed on both soft and hard wood.Adult beetles lay eggs in crevices of wood.When, larave hatch tunnels inward,adults break through the surface leaving tiny round or oval shape pin holes.                                                                       

Adults lays eggs in open pores of wood.  Larvae eat into wood causing honeycomb.  After pupating and becoming adults, they bore out of the wood leaving behind small holes and a pile of powder or "sawdust".

Wood Fungi

A wood-decay fungus is a variety of fungus which has the ability to digest wood, causing it to rot. Wood-decay fungi include those which attack dead wood, such as dry rot, and those which are parasitic on living trees, such as Armilaria  (Honey fungus). Fungi that not only grow on wood but actually cause it to decay are called lignicolous fungi. They do not necessarily need to decay lignin in the wood to be termed lignicolous. Dry rot fungi decay cellulose in wood leaving behind the lignin as the brown crumbly remains.

Brown Rot

Brown-rot fungi break down  hemicellulose and cellulose. Cellulose is broken down by hydrogen peroxide (H₂O₂) that is produced during the break-down of hemicellulose. Because hydrogen peroxide is a small molecule, it can diffuse rapidly through the wood, leading to a decay that is not confined to the direct surroundings of the fungal hyphae. As a result of this type of decay, the wood shrinks, shows a brown discoloration, and cracks into roughly cubical pieces; hence the name  brown rot or cubical brown rot.

Soft Rot Fungi

Major cause of failure in hardwood transmission poles and other hardwood products that are in ground contact.

Usually start on the outside of wet wood and works it way inward.  A slow and less obvious degradation.

The problem is that the hyphae grow strictly within the cell wall and never enter the cell lumen or pits where many treatments are restricted.

 BlueStaining Fungi

Do not destroy wood - only degrade it.

The dark color of the hyphae causes the wood to look blue or black thus losing its appearance value.  Also, because it destroys the pit membranes, it makes the wood more permeable.

Staining fungi live on sugars in cell lumen; therefore, hyphae are in lumens and through pits to other lumens.

Black Mold

Grows on surface of wood where moisture content is 20 - 25 percent.

The mycellium are usually clear but the fruiting bodies are dark, giving the surface a very dirty look.

Moldcommonly grows on wooden surfaces, as wood is very good at absorbing water. Add to this moisture warm temperatures and mold spores (which are always in the air), and it's the perfect storm for a mold infestation.



How to choose proper wood preservative

One has to decide which preservative to use for specific purpose.

Below are the guidelines to decide wood hazard class and accordingly one can choose preservative system.
