Borates provide an effective method of treating for the protection of wood and wood-foam composite structural components against wood decay fungi. Borates are highly destructive to all wood destroying organisms and, unlike other wood preservatives, they are non-volatile, odorless, and are less toxic than table salt.
How do you treat wood decaying fungi?
No chemical treatments are recommended for wood-rotting fungi, and destroying the conk, or the white fungal growth at the base of the tree, is useless—the fruiting bodies are only an indication of extensive inner rot. Remove and destroy diseased wood.
What kills fungus on timber?

What kills dry rot fungus?
Boric acid (borate) is one of the most effective fungicides for use in treating wood rot. It can be applied to wood during construction to prevent future rot, or as a treatment to stop an active decay fungus from growing.
What causes fungus in wood?
Fungus on wood requires four specific things to thrive: oxygen, favorable temperatures, water, and food. This happens when the moisture content of wood exceeds 20 to 30 percent, coupled with an ideal temperature of between 40 and 90 degrees Fahrenheit.
What does dry rot fungus look like?
Identifying Dry Rot
grey-whitish ‘skin’ tinged with yellow and lilac patches. mushroom-like fruiting body – soft, fleshy and looks like a pancake or a bracket – often orangey in colour, rust coloured in the centre, with wide pores. red dust from spreading spores, often found around fruiting bodies.

What are the two groups of wood destroying fungi?
There are many different types of brown rot fungus, but those causing the most damage to the wood humans use are Serpula lacrymans, what experts call ‘true’ dry rot, and Coniophora puteana, a cellular fungus which attacks timber in buildings.
How quickly does dry rot spread?
Dry rot can spread up to 80 mm per day, if it has optimal conditions for growth. In order to achieve this intense growth, dry rot needs temperatures between 66- and 70-degrees Fahrenheit. Further, unlike many other fungi, dry rot does not need a lot of moisture to grow quickly.
