Abstract
The use for combating wood damaging fungi of compounds of formula (I), where R is (a) or (b), where each R1, which may be the same or different, is C1 4 alkyl, C1 4 alkoxy, trifluoromethyl or halogen and n is 0 to 3.
Description
The compound of formula I can be applied in a suitable, usually liquid formulation, usually containing surfactants and other conventional additives and usually after dissolving with water. The concentration can vary over a wide range, for example 0.001 to 0.0%, preferably 0.1 to 1% by weight.
The invention illustrates in the following examples, Example 1 In vivo test of activity against fungi that destroy wood. 10 cm of chamfered edge boards of freshly cut pine were cut into 20 cm sections. Each duplicate sample consisted of six boards stacked alternately to form a block of a height of 6 boards. Three duplicate samples were used per treatment. Each duplicate sample was treated separately but with the same treatment solution of a compound to be tested. The complete set of 6 boards was immersed in the test solution, leaving a 1 cm longitudinal strip completely clear. The boards separated slightly to allow free movement of the treatment solution between them. The time of
The treatment was approximately 10 seconds after which the boards were removed from the treatment solution, the excess liquid was drained and the boards were placed in a polyethylene bag. This bag had a small hole in its underside to allow excess moisture to be drained, while allowing high humidity to be maintained. The boards introduced in bags were kept in a greenhouse at 18 ° C in natural light. The sets were kept as a single layer and were not stacked. The sets were then turned over periodically to ensure a moisture content as consistent as possible within the set. The evaluation was done 5 weeks after the treatment. For each duplicate sample, the adjacent faces of the neighboring boards were visually evaluated in% of fungus infection by sapwood coloration% of area covered by the colonization of basidiomycetes and
% of surface colonized by sooty molds. Since there were 6 boards in the set, this gave 5 readings in duplicate, the control values being calculated based on the levels of infection of the untreated boards. The treatment was carried out in 10 EC of a compound
A (example 59 of documentf WO 9636615), diluted to the desired concentration,
Claims (1)
- characterized in that cadm R 1, which may be the same or different, is C 1 -C 1-4 alkoxy, trifluoromethyl or halogen alkyl and n is 0 to 3.
