Description of key information
The effect of CA 2343 A on the seedling emergence and survival of monocot (wheat [Triticum aestivum]) and dicot (radish [Raphanus sativus] and lettuce [Lactuca sativa]) crops was studied at nominal concentrations of 0, 1, 10, and 100 mg test substance/kg dry soil. The growth medium used in the seedling test was artificial soil (sand soil, pH 7.7, organic matter 2.8 %). Each seed with plant tissue above the soil was considered germinated. The surviving plants per pot were recorded and cut at soil level for measuring the shoot dry weight.
Seedling emergence was not affected by the treatment of CA 2343 A. There were no adverse effects on the seedling emergence or survival of lettuce, radish, or wheat for up to 18 days after planting, and no significant (p>0.05) reduction of shoot dry weights in the treated species as compared to the control. Therefore,the EC50and LC50values for lettuce, radish, and wheat were determined to be greater than 100 mg/kg, the highest concentration tested.
