Fabr. on seven poplar clones was estimated on a short rotation plantation which was established near Junkovac (MB Kolubara). The highest percentage of trees with Gypsy moth caterpillars present was found in clones “Panonija” and “I214”, although the percent is twice lower in the latter clone. In clones produced by hybridization of Populus nigra and P. maximowicziii and “Koltay”, the number of trees with Gypsy moth caterpillars varied between 1% and 2.5%, and the lowest value was recorded in clone “Muhle Larsen”. The fungus Pollacia elegans was mostly present in clones produced by hybridization of Populus nigra and P. maximowicziii “Max 1”, “Max 2”, “Max 3”, while its presence was significantly lower in clones “Koltay”and “Panonia”. The presence of this pathogen was recorded in less than 5% of plants in clones “I214” and “Muhle Larsen”. Izvod: U plantaži sa kratkom ophodnjom koja je osnovana u blizini Junkovca (RB Kolubara) istraživano je prisutvo gusenica gubara Lymantria dipar (L.) i patogena Pollacia elegans (Vuill.) Fabr. Na sadnicama sedam klonova topole. Najviši procenat stabala sa prisutnim gusenicama gubara nalazimo kod klona „Panonija“ i „I 214“, mada je taj procenat kod drugog klona duplo niži. Kod klonova nastalih hibridizacijom Populus nigra i P. maximowicziii i „Koltay“, broj stabala sa gusenicama gubara je varirao od 1 do 2,5% a njanižu vrednost beležimo kod klona „Muhle Larsen“. Gljiva Pollacia elegans je najprisutnija kod kolonova nastalih hibridizacijom Populus nigra i P. maximowicziii, „Max 1“, „Max 2“, „Max 4“, dok je značajno manje prisutna kod klona „Koltay“ I „Panonia“. Prisustvo ovog patogena beležimo na manje od 5% biljaka kod klonova „I214“ i „Muhle Larsen“.
