COMPARISON OF THE EFFECTIVENESS OF VARIOUS ORGANOTIN COMPOUNDS WITH 2-THIOCYANOMETHYLTHIOBENZOTHIAZOLES AS ANTIFUNGAL AND ANTI-MOLD WOOD PRESERVATIVES

The anti-fungal and anti-mould effect of 17 organotin compounds on bro wn rot fungi Conidiophora puteana and Serpula lacrymans, and a mould m ixture of five strains, Aspergillus amstelodami, Aspergillus niger, Pa ecilomyces veriotti, Penicillium cyclopium and Penicillium brevicompac tum was assessed. The best inhibitory effect of the tested compounds w as confirmed for tributyltin compounds. The effect of phenyl- and benz yltin compounds was weak both for fungi and moulds. The most sensitive subject was S. lacrymans, It can be concluded that the results with T BTL (tributyltin linolate) and TBTN (tributyltin naphtenate) as antifu ngal agents are relatively good. The TCMTB compounds (Busan 30 L and B usan 30 WE, each containing 30% TCMTB) were effective mainly against m oulds.
