Depending on the danger to which the wood is exposed, appL ication for preservation of the wood may be off ected, for examp~e, a) by spraying the wood with the solution, b) by dipping the wood into the solution, G c) by impregnating the wood by means of pressure differences, for example by the pressure process or double v a cum impregnation, or d) by spreading the preservative over the wood, In the case of secondary wood produc ts, for examp~e cut wood and pulp, and other indlustr ial products or 00eL (ulose'-ton t a n ing ma teori a s whicqh. a re suscePp t ib le to fungal attack, for exampLe intermediates in papermak ing, ligneous annual plant4 (bagasse, rape) the appl icat ion s hou Ld be adap tqd to the tecohnI oa L po s s ib41ilt ios The wood-preserv Ing atct ivi ty of the aq~nt~s Oovers, for example, a) 61ol(ds (e g.

Ter: sample boards were impregnated with each individuaL test soLution in the manner described above. Unimpregnated controL timbers were dipped into pure water.
The test area chosen was a shady meadow, whose grass was cut short before the'test timbers were Laid out. The test timbers were pLaced on two pLastic raiLs, at a height of about 1 cm above the grass.
The test boards exposed to outdoor weather (rain) were checked after two months (August/September).
The fungicidlaL activity was classified in four categories on the basis of the resulting discoLoration and changes in the wood surface; 0 No overgrowth Slght spot-like superficial overgrowth More extensive spot-(likq overgrowth Large areas of overgrowth or completely overgrown.
