Three plant extract compounds (fatty acids, polysaccarides and viatmins)
and one nematicide (Furadan 10% G.) were evaluated for their efficacy against
Meloidogyne javanica on potato plants under greenhouse and field conditions. All
plant extract compounds tested reduced the nematode galling on the root system and
inhibited nematode reproduction. Among the three plant extract compounds, vitamins
had the highest effect in reducing nematode infection under greenhouse and field
conditions, Nematicide Furadan 10% G. had the best control for M. javanica on potato
plants. A" the plant extract compounds had astimulatory effect on the pctato plant
growth. Data either under greenhouse or field conditions were similar.
