Molds (Trichoderma, Penicillium...)

In recent years, a very significant increase in the proliferation of MOLDS (Trichoderma, Penicillium…) has been observed.

When a sawmill cuts down a round tree to obtain boards and planks, this wood will always be subject to attack by FUNGI and MOLDS, since different types of mold are present in the environment. concentrations of the spores of these microorganisms. Depending on the time of year the concentrations of spores are different and thus, the risk of attack, and its virulence, also varies.

In recent years, a very significant increase in the proliferation of MOLDS has been observed.

(Trichoderma, Penicillium…). One of the explanations that takes more strength is the proliferation of called «ecological agriculture» and the use of agrochemicals of biological origin that use molds as an active agent (the most used are of the genus Trichoderma and Penicillium) that aim to protect crops from certain fungal attacks (by direct competition).

These colonies of MOLDS, which in themselves are not harmful to crops or to human beings, are creating a serious problem throughout the world for the Timber Sector.

Mold spores are present in the environment: in water, in the air, in vegetation, on the ground… they can come from waste, log yards, forests, stagnant water, diseased trees… the spores are invisible to the eye.

It must be taken into account that many of these microorganisms do not respond, for the most part, to conventional treatments against bluing. So you have to find the right biocide to control each type of MOLD .

The presence of mold in wood does not affect the structure or the physical properties of the wood, but it severely modifies its appearance and aesthetic quality, causing a great decrease in its economic value.

Molds appear as amorphous growths on the surface of wood with a wide variety of colors and appearance. Coloration can range from white, pink, brown, green to black.
