The present invention relates to fungicidal compositions com-prising a quaternary ammonium compound and a guanidine component consisting of a guanidated aliphatic diamine or polyamine. The compositions are par-ticularly useful for the protection of wood and wood based materials against wood destroying fungi.
Description
~ )16~5 The present invention relates to fungicidal compositions com-prising both a) a quaternary arnmonium compound and b) a guanidine component said component being a guanidated aliphatic diamine and/or a guanidated aliphatic polyamine.
The components of the present compositions have previously each separately been employed as fungicides. Quaternary ammonium compounds such ~ ' as alkylbenzyl dimethylammonium chloride have been used for protection of wood, e.g. for protection against soft rot. Guanidated aliphatic diamines and polyamines have predominantly been used in horticulture and agriculture ;
for control of soil and seedborne fungi.
It has now been found that mixtures of quaternary ammonium com-pounds and guanidated amines not only give an additive effect but also a synergistic effect. ~ixtures of active components according to -the inven-tion give an unexpected prolongation and also a widening of the fungicidal effect which cannot be attributed to an additive effect.
` The quaternary ammonium compounds useful in the compositions of the invention can be represented by the general formula R
R'- ~- R"
R"' wherein at least one of the groups R is a higher carbon chain, i.e. a straight or branched, substituted or unsubstituted aliphatic group having -6 to 24 carbon atoms. As example of an inert substituent in the higher aliphatic group can be mentioned an ether group. The quaternary ammonium compounds contain one or two higher groups while the other substituents R
independent of each other are alkyl or hydroxyalkyl groups having 1 to 1~
carbon atoms or benzyl groups. Two of the other substituents can also form a piperidine or morpholine eroup with the nitrogen atom. The anion is pref-erably chloride but can of course be replaced by other ions such as bromide, ethyl sulphate ion etc. The quaternary ammonium compound suitably contains one or two alkyl groups having 6 to 24 carbon atoms and preferably 8 to 1~
carbon atoms. As examples of suitable fung~.cidal quaternary ammonium com-- ~k "

.~5 pounds for use in the present compositions can be mentioned didecyl dimethylammonium ch~oride, cetyl trimethylammonium chloride, alkyl ben~yl dimetnylammonium chloride and other quaternary ammonium compounds wherein the chain length distribution of the higher alkyl group or groups corre-sponds to that of naturally occuring substances such as that of coconut acid, cetyl dimethyl ethylammonium ethylsulphate etc.
~he guanidine component of the present compositions is at least one guanidated aliphatic diamine or at least one guanidated aliphatic poly- -amine, which includes triamines, tetraamines and higher oligomers or a mix-ture of guanidated diamines and polyamines. Because of the base strength of the guanidine groups the guanidated amines are generally present as acid addition salts, e.g. chlorides, sulphates, nitrates, acetates, formates, stearates, oleates etc.
The guanidine component can be represented by the general formula X - HNRl - (~R2)n - N~I - X (I) wherein X is hydrogen or a carboxamidine group, i.e. the group H
-C \ . In the carboxamidine group one or several of the hydrogens ~H2 may be replaced b~ alkyl groups having 1 to 4 carbon atoms. Preferably X
as a carboxamidine group is unsubstituted. Rl and R2, independently o~
each other are aliphatic groups having 3 to 14 carbon atoms, suitably alkylene groups having 6 to 12 carbon atoms such as hexyIene-, heptylene-, octylene-, nonylene-, decylene-, dodecylene groups or cycloalkylene groups such as cyclopentylene-, cyclohexylene-, cycloheptylene- or cyclooctylene groups. Most preferably the alkylene groups contain 6 to 9 carbon atoms.
In the formula n=0-6, preferably 0-4. The groups R2 do not necessarily have to be the same when n~l.

protection against blue fungi is particularly improved with the composi-tions. All kinds of wood and wood based materials which are susceptible to wood destroying fungi can be protected by applying the present compositions using conventional methods such as dipping, spraying, coating, impregnation.
The invention also relates to a process for protecting wood and wood based materials against wood destroying fungi which comprises treating the materials with a fungicidal composition comprising a quaternary ammoniurn compound and a guanidine component consisting of a guanidated alipha-tic diamine or polyamine, or acid addition salt thereof.
The two active components of the compositions are cationic and t.hus a very good retention to the negatively charged cellulose material is obtained. Additional substances for facilitating the retention of the com-positions to wood are thus not necessary. Further the active components are soluble in water so that the hydrocarbon solvents which are generally used for wood preservatives and which are undesirable from a toxicological point of view do not have to be used. The compositions can of course never-theless form part of all conventional kinds of formulations including powder formulations. The present compositions possess a further advantage compared with generally used substances for wood protection, such as pentachloro-phenols and bifluorides, in that the components have negligible vapour pres-sures and thus do not give off vapours which is a considerable advantage from a toxicological and environmental point of view.
The concentration of the active components in liquid formulations for use as wood preservatives is generally within the range of from 0.1 to 10 per cent by weight. The concentration is however not critical but is adapted with respect to the desired protection and the kind of wood.
The compositions according to the invention have both a prophy-lactic and a curative effect and can beside the above mentioned application also be used for disinfection of timber drying equipment and of buildings .
and other constructions which have been attacked by mould and rot. For . .

They can also be used for fibre materials such as paper and textiles and can hereby be inserted in different steps of the respective production process, they can for example be added to a pulp sus-pension at paper production.
The invention also relates to the compositions in combination with diluents and additives known per se and it is also within the scope of the invention that the compositions can form part of formulations containing other known fungicidal and pesticidal substances.

Pine discs having a thickness of about 1 cm and a diameter of about 6 cm were dipped into a spore solution containing spores of blue fungi. The discs were thereafter allowed to dry for 5 to 10 seconds and subsequently dipped into water solutions of the components a) and b) re-spectively and compositions of these components. The discs were dippedinto the solutions for 5 to 10 seconds and thereafter dried for about 20 seconds. Two identically treated discs were placed in plastic bags to-gether with a reference disc which had been dipped only into the spore so-lution. The bags were closed and stored at room temperature.
Visual inSpeCtiOD of attack in relation to the reference disc were made at different times after the infection according to a scale o-4 where 0 stands for no attack, 1 a tendency to attack, 2 attack, 3 severe attack and 4 very severe attack. The results are shown in the Table below.
