Question

19. mája zistené postupné usychanie starých ihlíc od špičky (bazálna časť od brachyblastov zostávala dlho zelená). Postupne uschli celé ihlice, následne celé časti koruny až napokon uschol celý strom. Zaujímavé bolo, že májové výhonky spočiatku prirastal

Answer

Zdravím, príde mi to ako sypavka napr. Dothistroma septosporum, Lophodermium sp. Vylúčil by som Sphaeropsis sapinea a podpňovku. A zrejme to nie je ani listožravý alebo podkôrny hmyz. Sypavkám vyhovuje vlhkosť, čo v jari bolo čiastočne zabezpečené chladným počasím. A ide zrejme aj o prehustený porast. Hubu by bolo potrebné potvrdiť prítomnosťou na ihliciach. ale mohlo by ísť ešte aj o čokoľvek iné. Pošlite vzorky, alebo prídeme pozrieť ak sa to nezastavilo. Andrej Kunca

Question

Dobry den, O akeho skodcu by sa mohlo jednat? Napadnute listy postupne zozltnu uplne a odpadnu. Tie cierne bodky su vo vnutri listu, nie su to vykaly na povrchu. Taktiez su listy trochu zvinute dovnutra, aj ked si myslim, ze strom polievam dostatocne. Viete poradit aj ako treba zakrocit, aky postrek pouzit? Dakujem

Answer

Mohlo by ísť o Apiognomonia erabunda, tá napáda list od listovej stopky a list žltne. Nie je zrejmé, že by to bol ten prípad. Drobné čierne škvrny na listoch by mohli byť po infekcii hubou Cercospora, gnomonia, a iné. Možnože by som odlomil napadnutý list a spálil. Ak je ozaj infikovaný, nech sa infekčný tlak nezvyšuje. AK.
