Abstract


Our research aims to assess the chestnut tree health status in three various locations: Baia Mare, Tauti Magheraus, Baia Sprie, in order to find the most efficient methods to prevent and to combat the bark cancer which develops in the clime conditions of Baia Mare basin. The primary assessment was performed through the determination of the attack degree (AD %), of its frequency (F%) and its intensity (I%) . We took in observation 10 chestnut trees from each location. We determined the number and size of both trunk and branches lesions for each chestnut tree. The intensity of the attack in the three studied areas ranked from the highest intensity 47.5% for Baia Sprie location followed by the intensity of 33.0 % for Tautii Magheraus, to the intensity of 26.5% for Baia Mare. Our analysis performed after the administration of the combat chemical method, we found that this measure was not efficient because the infection did not diminish; thus we recommend the dry chestnut tree elimination, its hygiene cuts, using the biologic combat.
