Additional information
The toxicity of bronopol on tomato plants (Lycopersicum esculentum) was investigated in a non-standardized seedling emergence during a test phase of 7 days [Thompson 1986]. Tomato seeds were germinated on water agar containing serial dilutions of bronopol ranging from 2 to 100000 µg/ml at 25 °C in the dark. After 7 days, percentage of germination, root and shoot length was determined.
Toxic effects on tomato plants were observed at 1000 µg/ml, however, no further details on the degree of effects and the endpoint investigated were given.
In another plant study, seeds of the orchid Cattleya aurantiaca were germinated on Knudsons C medium and seedlings were then transferred to the test media under aseptic conditions in 100 ml bottles at 22 +/- 2°C and a day-night-regime of 12:12 h at 0.8 mw/cm2 light intensity [Thurston, 1979]. The development of the plants (growth index) was measured after 3 months according to the growth index of spoerl after exposure to 0, 50, 250 and 500 ppm bronopol. Growth indices were as follows: 557 +/- 27, 547 +/- 12 and 520 +/- 6 at 0, 50 and 250 ppm. At 500 ppm bronopol, the seedlings died and therefore no growth index could be determined.
Conclusively, effects on plant seeding emergence of tomato plants after exposure to bronopol was observed at 1000 µg/ml after 7 days and to orchids at 500 ppm after 3 months.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
