Armillaria root rot dynamics in the experimental plantation with Scots pine (Pinus sylvestris L.) seedlings non-mycorrhized and mycorrhized with the fungi Hebeloma crustuliniforme and Laccaria bicolor

The objective of the research was to study the Armillaria root rot dynamics in the experimental plantation with Scots pine (Pinus sylvestris L.) seedlings non-mycorrhized and mycorrhized with the fungi Hebeloma crustuliniforme and Laccaria bicolor. It was demonstrated that eight years after planting, the container-grown pine seedlings mycorrhized with the fungi H. crustuliniforme were affected by the Armillaria root rot disease in relatively lesser degree in comparison with the seedlings subjected to such treatment.
