Chemotherapeutic action of alanine as soil drench against root-knot nematode, Meloidogy ne incognita on Vigna unguiculata

Various concentrations of aminoacid alanine as soil drench were found to suppress the reproduction and population build up of Meloidogyne incognita on Vigna unguiculata and also improved the plant growth. The growth was found to be maximum in infected plants treated with 1000 ppm concentration of amino acid. Infection resulted in sugar depletion and elevated protein, lipid and phenol levels in the host plant. The activities of dehydrogenase enzymes and total endogenous reductases were more in the infected and infected treated plants. The reduced galling coupled with the improved plant growth and the enhanced organic constituents indicated the improved vigour of the host plant under the influence of alanine treatment.
