Abstract
The effect of second stage larvae of the Southern root-knot nematode Meloidogyne incognita on the growth of Ammi majus. chlorophyll and total phenolic content in leaves have been determined. With increasing inoculum densities of nematode there was a corresponding decrease in root-shoot length, fresh and dry weight of plants, total chlorophyll content and an increase in total phenolic content in leaves. The highest rate of nematode reproduction was found at the lowest inoculum level and lowest rate of nematode reproduction at the highest inoculum level.
