Effeect o f sonze ?zenzaticides o n root-knot nenzatodes (Meloidogyne spp.) o n ueget~~l7lcer ops in Portugal. Nematode contro1 trials were carried out in Portugal, against ilfc~loidogynein cognita race 3 on cucunlber in a plastic l-iouse in Torres Vedras, and against M. arnxai-ia race 3 o11 outdoor tomato in Azambuja. The results showed significant yield increases on cucumber with metham sodiurn applied one month before planting; and on tomato with metham potassium applied one month before planting or fenamiphos 240 CS applied one day before planting. In both trials, yields were f~irtherin creased by applications of either the granular or the microcapsulatecl formulation of fenamiphos, one day before or one month after planting.
