Abstract
In an attempt to find a substitute for Nemagon
five nematicides were tested for the control of rootknot
nematodes on tomato. Mocap was quite effective
in root-knot control in nursery seedlings but phytotoxicity
was observed when applied at dosages equal
to or higher than 10 kg a.i per hectare, the dosage
recommended by the manufacturer. Although Nemacur
was very effective in the nursery, it has a very
high mammalidn toxicity which makes the compound
rather dangerous to be recommended now. DD and
Basamid were found effective. Basamid however stays
too long in the soil at phytotoxic level during the
rainy season (more than four weeks). Vydate was the
most effective compound in the trial in terms of rootknot
control and fruit yield increase; but it has a
high oral toxicity, though its dermal toxicity is low.
Yield increase ranged from 10% in Mocap, to 87% in
Vydate-treated crop at the recommended dosages
