Škodljivi organizmi in škodljivi dejavniki na sadikah gozdnega drevja v obdobju 1997-2018

Pests and diseases together with harmful abiotic factors present a serious problem for the production of healthy and vital forest tree seedlings. In order to examine the most important and most frequently occurring harmful abiotic and biotic factors, we analyzed the annual reports of health...
