Abstract
In two-year field experiments (2014 and 2015), the effect of used preparations on health status of leaves and roots and bulbs on two cultivars of garlic: ‘Arkus’ and ‘Garpek’ was studied. During investigations: Polyversum WP (Pythium oligandrum), Trifender WP (Trichoderma asperellum) and RhizoVital 42 (Bacillus amyloliquefaciens) and standard fungicide Topsin M 500 SC (tiophanate methyl) were used. Unprotected plants presented control. The obtained results showed that in the first year of the studies, all the tested formulations effectively protected the roots and bulbs of garlic against rot, except RhizoVital 42 for ‘Arkus’ variety and Trifender WP for cultivar ‘Garpek’. In 2015, all tested preparations, without exception, limited root rot and the rot of basal part of bulbs both cultivars of garlic. The applied biological preparations had no significant effect on health of the leaves of garlic in 2014 and in 2015 for cultivar ‘Garpek’, while in the second year of studies, all the tested formulations effectively limited the dieback of leaves of the garlic cultivar ‘Arkus’.
