Disclosed is a biocide concentrate composition to be incorporated into oil-based formulations useful for the treatment and preservation of wood. Also disclosed are oil-based biocide compositions and creosote based biocide compositions.

Disclosed is process of preserving hardwoods with ammoniacal copper, ammoniacal zinc or ammoniacal copper and zinc compounds. The preserved hardwoods are useable as various articles of manufacture and, in particular, railroad crossties and switch ties.

Fungicidal mixtures having synergistic fungicidal activity may include penflufen and at least one further fungicidal material. The mixtures may be used for protecting industrial materials, and methods for treating industrial materials with the penflufen mixtures are provided.

The present invention provides a wood preservative formulation comprising an isothiazolone, an organic fungicidal timber decay preservative and an unsaturated carboxylic or sulphonic acid, salt or anhydride thereof. The formulations of the invention are surprisingly effective at protecting wood and other cellulosic substrates, in particular at providing prolonged protection against in-service surface staining. The invention also provides methods for treating wood and other cellulosic substrates with said formulations.

A solid body of dazomet for use in internal remedial treatments of wood and methods of applying such solid bodies to wooden structures and manufacturing such solid bodies. The solid bodies can be easily transported and inserted into treatment holes in utility poles, wooden pilings, and other wooden structures, delivering a dose of insecticide and fungicide that combats internal decay in the wood.

A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.

The present invention relates to combinations of pyrimethanil, or a salt thereof, and a monoterpene, or a salt thereof, which provide an improved biocidal effect. More particularly, the present invention relates to compositions comprising a combination of pyrimethanil, or a salt thereof, together with a monoterpene selected from thymol and -thujaplicin in respective proportions to provide a synergistic biocidal effect. Compositions comprising these combinations are useful for the protection of any living or non-living material, such as crops, plants, fruits, seeds, objects made of wood, thatch or the like, engineering material, biodegradable material and textiles against deterioration due to the action of microorganisms such as bacteria, fungi, yeasts, algae, viruses, and the like.

Methods of applying an agent to an area, such as methods of applying an agent to an area under cultivation, including providing wood fragments that have been treated to absorb the agent, and dispersing the wood fragments about the area under cultivation; methods of creating a fire-resistant area, including providing wood fragments that have been treated to absorb a fire retardant, and dispersing the wood fragments in an area to create the fire-resistant area; and methods of fighting a fire, including providing wood fragments that have been treated to absorb a fire retardant, and dispersing the wood fragments onto the fire.

A method for producing a modified wooden material. Specifically described is a method for producing a modified wooden material, the method including: 1) a step for causing permeation, into a wooden material, of a 5-hydroxymethylfurfural (5-HMF) resinification solution containing 5-HMF and an inorganic salt for promoting polymerization of the 5-HMF; and 2) a step for polymerizing the 5-HMF of the permeated 5-HMF resinification solution in the wooden material by means of heating.

A wood preservative composition comprising 4,5-dichloro-2-octylisothiazol-3(2H)-one, a method of treating a wood substrate therewith, and a wood product produced therefrom are provided. The wood preservative composition comprises at least 0.5% by weight of DCOI based on the total weight of the composition and a retaining additive comprising a solvent-borne polymeric resin, a wax, or a combination thereof. A weight ratio of the DCOI to the retaining additive in the composition is in a range of 1:5 to 5:1.
