Question

Dobrý deň. V spodnej časti kmeňa javora mliečneho je poškodenie s drevom v rozklade (na foto ako pásiky) a na nej a okolo sú čierne a hnedé povlaky. Kôra zasiahnutá čiernymi povlakmi sa ľahko odlupuje, láme a praská. Čierne povlaky vystupujú medzi borkou aj vyššie po kmeni. Na jednej fotke (na ľavej strane ako malý kopček) hore pod kôrou je vidno hnedú plodnicu. Neviete o akú hubu ide? Je to závažné poškodenie a ako to riešit? Dakujem za pomoc s určením a radou.

Answer

Zdravím, podľa mňa ide o bielu hnilobu dreva, ktorú vyvoláva niekoľko druhov húb napr. Armillaria mellea, a iné.Opísané "čierne povrazce" nie sú také, ako máva Armillaria mellea a to je dobré, lebo to je pre napadnutý strom nebezpečná huba! Skôr mi to príde, že je javor napadnutý hubou napr. Volvariella bombicina (https://www.skodcoviadrevin.sk/skodca/posvovec-stromovy), alebo aj inou. Vami opísanú plodnicu na kmeni nevidím. Kedže sa strom kalusuje, fyziologicky sa strom samolieči a má šancu žiť ešte desaťročie (a aj viac). Jadrová biela hniloba mu znižuje statickú stabilitu a vo vetre alebo pod tlakom snehu by sa strm mohol zlomiť. Treba zvážiť riziká a rozhodnúť sa, ako ďalej.

Question

tree located in spacious domestic garden with multiple shoots in upper canopy effected leading to some crown thinning

Answer

Hi Kevin, the damage you see on the willow is caused by Stenacis triradiatus, also known as the triradial willow mite. This microscopic mite creates characteristic galls and dense, twisted clusters of shoots called witches’ brooms. It overwinters under bud scales and becomes active in spring, feeding on young shoots, leaves, and catkins. If you have any further questions, feel free to ask. Best regards,Milan Zubrik

Zdravím. Požerok bol nájdený na rozštiepenom dubovom kláte. Dub s ktorého požerok pochádzal bol vyvrátený a čiastočne uschnutý. Domnievam sa že škodca bol Cerambyx Cerdo

Answer

Dobrý deň. Áno, požerok patrí takmer na 100% fuzáčovi veľkému (Cerambyx cerdo). S pozdravom JG

Question

Answer

Dear Andrea, Thank you for your inquiry. The information provided is not sufficient to determine the cause of the damage. If it is indeed an elm (the photograph does not make this entirely clear), it is worth noting that a whole group of bark beetle species from the genus Scolytus can affect elm trees. You can read more about them here: https://www.forestpests.eu/pest/scolytus-spp&rurl=YXRsYXMmYW1wO2ZpbHRlcj00OCZhbXA7cD00. However, other possible causes of the damage cannot be ruled out either. Have a nice day, M. Zúbrik
