Effect of Fruit Extract of Aegle marmelos on the Level of Biochemical Constituents of Horse Gram, Macrotyloma uniflorum, Infected with Root-knot Nematode, Meloidogyne incognita

Root knot nematodes, Meloidogynesp, are recognised as the most economically important genus of plant parasitic nematodes Worldwide. The nematode causes severe damage and yield loss to a large number of cultivated plants and especially on vegetable crops in tropics and subtropics. Hence, the present investigation has been done to study the efficacy of fruit extract of Aeglemarmelos on the root knot nematode, Meloidogyneincognita infecting the horse gram, Macrotylomauniflorum. From this study, different levels of egg masses (5, 10 and 15) were inoculated in the experimental plants treated with the fruit extract of A.marmelos with different concentrations (5,10 and 15 p.p.m) and analysed various biochemical constituents, such as, carbohydrate, protein, lipid, nitrate reductase activity and phenol content of the control and experimental plants after 45 days of treatment. These biochemical constituents are decreased with increasing inoculums levels of egg masses and these constituents are increased with increasing concentrations of fruit extract treatment except phenol content.
