Comparative performances of carbofuran and plant extracts in the control of root-knot nematode on pepper

Abstract

A field trial was carried out to compare the effectiveness of carbofuran and plant extracts from the roots of rattle weed and nitta plants in root-knot nematode control. Carbofuran was applied at 1.5 and 2.5 kg a.i/ha while plant extracts were applied at 25, 50, 75, and 100% concentrations. An experimental plot where neither carbofuran nor plant extracts was applied served as the control treatment. Both carbofuran and plant extracts significantly reduced the soil population of root-knot nematode and galling on the root of pepper, and also improved growth and yield of pepper. Pepper plants treated with carbofuran and 100% concentration of the plant extracts gave the best control of the root-knot nematode.
