Abstract
The effect of soil-incorporated copper, tri-allate, and anthracene on the emergence and early growth of three Australian native species (Banksia ericifolia, Casuarina distyla andEucalyptus eximia) and three crop species (Avena sativa, Cucumis sativus andGlycine max), was assessed using OECD Test Guideline 208. The crop species are sensitive species used in overseas phytotoxicity testing, and their responses were compared with those of the native species. Seeds were grown in pots in a glasshouse in a sandy loam soil at the chemical concentrations of 0, 10, 100, 1000 and 2000 mg kg−1. LC50 and EC50 values were determined for each species. The most sensitive species was the monocotyledonA. sativa, while among the five dicotyledonsC. distyla was most sensitive. All three chemicals delayed emergence and affected seedling growth. The results indicate that the conditions of the OECD Test Guideline can be met under Australian conditions, but that the Guideline requires modification for use with Australian native species.
