ABSTRACT
The effect of several amendments was evaluated against nematodes associated with peach (Prunus persica L.
Batsch) seedlings. Three major nematode populations were found in the soils including Helicotylenchus
pseudorobustus, Xiphinema americanum and Pratylenchus thornei. Soil containing nematodes was collected from
peach orchards near Kalat, Balochistan and filled in pots and peach seedlings were transplanted. Various soil
amendments were applied including sawdust, sugarcane bagasse, neem (Azadirachta indica) leaf powder and
marigold (Tagetes erecta) flower powder used alone and in combination with Fertinemakil. Untreated pots were
kept as control. Carbofuran a chemical nematicide was used for comparison. Subsequently after 8 weeks nematode
populations were studied. The results showed that amendments significantly influenced the nematode population
though the nematode populations themselves did not differ significantly. The effectiveness of various amendments
was in the order Carbofuran > Fertinemakil > marigold + Fertinemakil > neem powder + Fertinemakil against
Helicotylenchus pseudorobustus. With respect to Xiphinema americanum, Carbofuran > neem powder +
Fertinemakil > marigold + Fertinemakil > neem powder. While, Pratylenchus thornei was best abated by
Carbofuran > marigold + Fertinemakil > neem powder + Fertinemakil > marigold in that order. The role of different
nematodes associated with peach is discussed.
