Stock Photo - Pine tree is treated against the parasitic fungal disease Lophodermium seditiosum in Kolarovy sady, Prostejov, Czech Republic, July 13, 2023. The town hall has allocated a total of 61 trees in the town for professional treatment. In addition to pine trees, which are treated with a nutrient solution of phosphorus, potassium and trace elements, they also treat Aesculus species infested with the horse-chestnut leaf miner (Cameraria ohridella) using insecticides. Both methods are environmentally friendly, as they are injected directly into the treated tree. The substances reach all parts of the tree through conductive meshes. Trees in urban areas suffer stresses especially from the current drought, salinity by roadsides, soil compaction or paving. By administering a nutrient solution, the vitality of trees improves.
