2) Panogen (methyl mercury dicyandiamide, 2.2%) containing 1. 5% Hg, at 0.2%. + Ekatox 5%, at 0.4%.

3) Tillex - liquid (ethoxy ethyl hydroxy mercuri, 2.3%) with 1.5%. Hg, at 0,5%."+ Ekatox 5% at 0.4%.

4) Mercury Woodox (experimental) (phenyl mercury dimethyl dithiocarbamate, 95%), at 0.03%. + Ekatox 5%, at 0.4%.

5) Semesan (hydroxy mercuri chlorophenol, 30%), with 19% Hg, at 0.1% + Ekatox 5%, at 0.5%.

6) Polyram combi (activated zinc-tiuram-di-sulfide, 90%), at 0.5% + Ekatox 5%, at 0.4%.

7) PCNB (pentacholoronitrobenzene, 75%); at 0.5% + Ekatox 5%, at 0.4%.

8) Cuprosan azul (cooper oxichloride with 35% Cu, at 0.5% + Ekatox 5%, at 0.4%.
