Aerial parts of 27 plant species native to Argentina were tested in anti-insect, germination inhibition and bactericide bio-assays. In antifeedant assays on Epilachna paenulata larvae, 11 species showed strong feeding deterrent effects (higher than 90% at 200 ìg/cm2). Twelve plants strongly inhibited the germination of Avena sativa seeds, but only six inhibited Raphanus sativumEpilachna paenulata larvae, 11 species showed strong feeding deterrent effects (higher than 90% at 200 ìg/cm2). Twelve plants strongly inhibited the germination of Avena sativa seeds, but only six inhibited Raphanus sativumìg/cm2). Twelve plants strongly inhibited the germination of Avena sativa seeds, but only six inhibited Raphanus sativum germination at 10 mg/ml. Four plants showed complete growth inhibition of Escherichia coli at a concentration of 2 mg/ml.Escherichia coli at a concentration of 2 mg/ml.
