Use of vermiculite as substrate in assays on phytotoxicity of treated wood
1989 - IRG/WP 3547
It is considered the possibility of using vermiculite instead of soil as substrate in assays on phytotoxicity of wood treated with preservatives for agricultural use. Three organic preservatives were used. It had been tested the behaviour of both, vermiculite and soil in case of preservative leaking due to a leach. So that, assays of germination with cucurbitaceous were carried out, mixing a dose ...

The proposal for the method of testing the phytotoxic effect of wood preservatives
2000 - IRG/WP 00-50163
Four methods of testing the phytotoxic effect of wood preservatives are proposed as the unified test by: - direct application of the preservatives to the test plants by spraying; - direct application of the preservative to the soil substrate; - indication plants growing in the vicinity of treated wood; - seed germination rate on the treated substrate....

Phytotoxicity of selected wood preservatives
1999 - IRG/WP 99-50133
The treated wood is used commonly around our environment. The aim of the study was to determine the reaction of plants to the wood preservatives and wood treated with preservatives. The study was made comparatively with ten types of organic and water-borne preservatives. The white mustard (Sinapis alba L.) was chosen for use as bioindicator and the tests were carried out to determine the response ...

Phytotoxic effects of preservative treated props for agricultural use
1989 - IRG/WP 3550
The phytotoxic effect due to the use of wood treated with organic preservatives for agricultural purposes was studied. The assays were carried out on plants tutored with props of Pinus sylvestris treated with three different organic wood preservatives. Pre-assays were carried out to observe the reaction on the plants, spreading directly the preservative on different parts of the plant and to the s...

Determination methods of phytotoxic effect of wood preservatives
1990 - IRG/WP 2349
The phytotoxic effect of wood preservatives so widely used plays a considerable role in the protection of natural environment. A review was made of the existing methods with which to assess the phytotoxicity of the above chemicals and some suggestions were given concerning the methods most appropriate for their unification. Two areas of research are proposed: 1) estimating the direct effect on ind...
