Abstract
The object of studies were pea plants of cv. ‘Sześciotygodniowy Tor’ , whose seeds were dressed before sowing and which at anthesis were sprayed with 2.5% Biochikol 020 PC, 0.2% Biosept 33 SL and Polyversum (1g·100–1 seeds). Besides, the experiment considered a combination with chemical seed dressing of seeds with Zaprawa Oxafun T (2 g·kg–1 seeds) and spraying plants at anthesis with Bravo Plus 500 SC. Plants without any protective treatments constituted the control. During the vegetation field observations were performed in the phases of seedlings at anthesis of plants, establishing their number and healthiness. Besides, a mycological analysis was carried out of the infected parts at different developmental phases. The observations showed that among the studied biopreparations Biosept 33 SL proved to be the most effective in its protective action.
