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
