Abstract

Tobacco seedlings protection from the damping off disease caused by Pythium debarianum, long time has been performed only with the active substance propamocarb. But today, many preparations with new active ingredients have been registered.
The aim of these studies was to examine the efficacy of new fungicides and certain combinations, including commonly used ones. The investigations were performed by in vitro test, in 3 replications, including 6 fungicides and 4 combinations.
The standardly used Previcur N (0.15%) showed poorer results than some new or combination of preparations.
OrvegoTM (0.1%) did not give the expected results. However, when combined with contact fungicides Manfil 80 WP 0.25% and Enervin WG 0.2%, the effectiveness is 100%.
The Signum 33WG 0.1% fungicide showed 87.27% effectiveness. When combined with other preparations, the effectiveness is lower.
The best results in this studies (100% effiectiveness) were achieved by Quadris 25 SC (0.1%) as well as the contact fungicide Enervin WG 0.2%.
Fungicides, as well as high-efficient combinations in the control of P. debarianum will allow their application in the protection of tobacco seedlings from the damping off disease.
Keywords: Phytium debarianum, active ingredient, radial development, effectiveness
