Management of Meloidogyne incognita infecting Solanum melongena by using synthetic elicitor molecules

Foliar spray and root dip treatments with rose bengal (RB) and DL-amino-n-butyric acid (BABA) @ 25, 50, 100 and 200 g/ml were given to eggplants and the plants were challenged with root-knot nematode (RKN) juveniles. The elicitors reduced the number of root galls, final population of RKN and increased the growth parameters of eggplant. Both the elicitors were most effective at 200 mg/ml followed by 100 mg/ml concentration in foliar spray as well as root dip treatment. The root dip treatment proved more effective than foliar spray at each concentration. The RB proved more effective in reducing nematode infection than BABA in both the methods.
