Biogenic elicitors induce systemic resistance of plants to plant parasitic nematodes-Meloidogyne incognita and Globodera rostochiensis (decrease in the parasitic invasion of the roots; an inhibition of the vital activity of the parasite; a decrease in fertility and the amount of agents sources (larvae and eggs) capable of infecting the plants). The addition of signal molecules (salicylic and jasmonic acid) to elicitors increased their activity as immunomodulators. In present investigation the

... chanisms of induced plant resistance nematode were studied. The data obtained suggest that the mechanisms natural and induced by biogenic elicitors tomato resistance to the nematode have the same origin. These features meet all requirements of the new generation of methods of plant protection and the use of biogenic elicitors to raise plant resistance to parasitic nematodes may be promising.
