Current state of beech bark necrotic disease in Southern Poland

The degree of the beech bark necrotic disease was evaluated in three selected localities in southern Poland, in different orographic complexes, Beskid Sadecki, Beskid Niski, and Bieszczady. The degree is expressed by means of the stem necrotising index (ISN), crowns necrotising index (ICN), and whol...

Description
Summary:The degree of the beech bark necrotic disease was evaluated in three selected localities in southern Poland, in different orographic complexes, Beskid Sadecki, Beskid Niski, and Bieszczady. The degree is expressed by means of the stem necrotising index (ISN), crowns necrotising index (ICN), and whole tree necrotising index (INWT). The values of the indices laid in the following limits: ISN 0.73-0.84%, ICN 0.12%-0.51%, and INWT 0.84%-0.90%. The current status of the beech necrotic disease in Southern Poland can be considered as favourable. The values of ISN recorded in Southern Poland were lower by 30% than the average ISN for whole Slovakia. We also recorded the frequency of selected insect pests (Bucculatrix ulmella, Cryptococcus fagi, Ectoedemia liebwerdella) which act in the beech stands as vectors of the necrotic disease. With C. fagi, we recorded a high frequency reaching even 100%. In contrast, we did not observe the occurrence of B. ulmella and E. liebwerdella. We recorded the occurrence of two species of parasitic fungi of the genus Nectria causing the beech bark necrotic disease, viz. Nectria cosmariospora and N. galligena.
