INFLUENCE OF ROOT SYSTEM OF FLOWERING PLANTS ON DEVELOPMENT AND PRESERVATION OF Toxocara canis eggs (Werner, 1782)

The soil in the Vitebsk Region is contaminated with 11 helminth types from which the mostly spread is Toxocara canis. The research results on impact of rhizosphere of the Asteraceae family plants on eggs T. canis are provided. A high ovocidal efficacy of plant rhizosphere has been observed: marigolds – 74,03 %, calendula – 63,44, daisies – 53,83 %. The root system of Pelargonium zonale has a high expressed ovocidal (egg-killing) effect against T. canis eggs. The delay in helminth eggs development affected by rhizosphere of P. zonale will prevent the increasing of infected eggs in this time period and reduce the potential risk of infection spreads. Ovocidal effects of rhizosphere of P. zonale were not determined
