The principal criteria for a good wood preservative involves the following considerations 1. The preservative must be sufficiently toxic to curb the action of the wood rotting fungi and wood attacking insects 2. The preservative must not attack wood 3. The preservative must not undergo a chemical or physical change brought upon by contact with the wood cells so as to render the chemical agent non-toxic or less toxic 4. The preservative must not be a substance which will attack metals 5. The preservative must be of such a nature as to make it easily injected into wood 6. The volatility, chemical stability, penetrability, cleanliness, cost, toxicity to human beings and other similar factors must conform to the practical conditions under which the preservative is to be used. Although all of the above mentioned conditions are of high importance, the fact remains that the first consideration in selecting a wood preservative must be given to its ability to kill or to vitally inhibit the biological organisms which attack the wood. “Biological organisms” can be correctly construed as pertaining to both plants and animals. However, this discussion will be confined purely to the harmful effects of fungi upon spermatophytic plants and to the means by which the toxic action of chemical agents upon the saprophytic growth can be studied.
