Conteúdo: | Allicin-an active nematicidal principle in garlic has been isolated and tested against Meloidogyne incognita infesting tomato. Allicin resulted in 11-75 eggs hatched at 5-0.5 ppm compared with 146 hatched at 0 ppm after 120 h. A juvenile kill of 87-100% at 2.5-5.0 ppm allicin wasrecorded within 72 h. Concentrations of 200 and 100 ppm allicin as bare-root dips for 30 min killed 83% and 87% of tomato seedlings, respectively. Penetration of tomato roots by juveniles was 13%, 14% and 18% in seedlings wich had been dipped in allicin at 200, 100 and 25 ppm for5 min, respectively, compared with 36% in untreated seedlings. Allicinat 25 ppm for 5 min as a root-dip treatment for tomato seedlings is effective against M. iincognita.
