Sterowana mikoryzacja i doglebowa aplikacja fungicydów w hodowli dębu szypułkowego. I. Kolonizacja mikoryzowa i wzrost sadzonek z zakrytym systemem korzeniowym w szkółce

The aim of the study was to examine the level of mycorrhizal colonization and annual growth of oak seedlings, grown in two peat−vermiculite substrates mycorrhized and not mycorrhized with the vegetative inoculum of Hebeloma crustuliniforme after soil application of the fungicides Siarkol Extra 80 WP and Falcon 460 EC. The fungicides were applied at a single dose (i.e. equivalent to the amount of the fungicide that a seedling potentially receivable by a seedling in foliar application recommended for oak protection in forest nurseries), a double dose and a triple dose.
