| Abstract | ||||
| In present study four different amino acids i.e. DL-Valine, DL-Methonine, DLAsparagine and DL-Arginine with five different concentrations (50, 100, 150, 200 and 400 mg/ml) and two different application methods (soil drench and foliar spray) at two different application times (three days before and three days after nematode inoculation) were tested under both laboratory and greenhouse conditions to evaluate their influences on root-knot nematode Meloidogyne javanica and growth criteria of treated tomato plants. The results revealed that all tested amino acids at concentration of 400 mg/ml reduced significantly both eggs hatching and juveniles’ viability compared to control (nematode treated with tap water) under in vitro conditions. The highest percentage of non-hatched eggs (68%) and dead juveniles (81%) was recorded by DL-Methonine amino acid followed by DL-Asparagine which percentage of non-hatched eggs and dead juveniles recorded 60% and 80%, respectively. | ||||
