Abstract: The requirements for the production of fresh pesticide-free and organically cultivated vegetables increase the interest of the farmers to the problems of the resistance and the tolerance of crops and addressing the impact of biotic stress factors.
The influence of Fertiactyl® GZ on the host-parasite interactions was studied on the system tomato – Meloidogyne spp. under glass. The tomato variety Rally was used. The treatment with Fertiactyl® GZ positively affects the growth of the infected plants. The values of the examined parameters have been elevated compared with untreated variants; significant differences have been found in the fresh weight of the plants, which was 32.5% higher and in the fresh weight of the root system – by 9.1%. Although an increase in the density of nematodes has been reported, the growth and the development of the infected plants has been improved, which gives grounds to assume that this is due to the effect of the induced tolerance.
