Abstract
The potential nematicidal effects of 18 Chilean plants were evaluated on garlic (Allium sativum) seed cloves infected with Ditylenchus dipsa ci Cloves from infested fields were treated by immersion for 24 hours in plant extracts derived from fresh or air-dried plant parts. The gar lic cloves were potted and allowed to grow for 14 weeks under outdoor conditions. At harvest, complete control of the nematode was achieved with fresh extracts from leaves of Plantago major and Ruta graveolens and resulted in the highest quality plants. Extracts of Aristotelia ch ilensis, Chenopodium ambrosioides, and Ovidia pillo-pillo reduced (P l ess than or equal to 0.05) final nematode densities and disease sympto ms compared to untreated control plants. None of the other plant extra cts showed nematicidal activity against D. dipsaci.
