Phytotoxicity Test in the Development of Ecofriendly Pesticides

In the current debate on pesticides causing environmental damage, the search for ecofriendly pesticides is gaining importance. Plants frequently contain compounds that counteract fungi or other plants; thus, such substances might be used in agriculture. However, it is important to rule out potential dangers before applying them in practical use. Therefore, a comprehensive ecotoxicological assessment is important.

In this context, a Lemna paucicostata growth inhibition test carried out with a LemnaTec Scanalyzer at USDA-ARS assisted in determining phytotoxicity. The researchers identified three plant-derived substances exhibiting moderate herbicidal activity that can be candidates for further developments.
