Method for treating wood against the attack of harmful fungi

The present invention relates to multi-phase aqueous suspoemulsions and to their use for the treatment of timber against attack by fungal timber pests. A multi-phase suspoemulsion containing as essential componentsa) 1 to 50% by weight of particular fungicidal benzimidazoles or precursors liberating them as microsuspended solids particles,b) 5 to 60% by weight of an emulsion comprising a fungicidal ingredient (b) and, in combination with (b), at least one component (b) or (b),in a water diluted form is useful to protected timber against fungal timber pests; (b) represents the fungicidal compounds fenpropimorph, fenpropidin, tridemorph, aldimorph and spiroxamine, (b) represents particular azole fungicides, and (b) represents particular benzoic esters.
