Question

Answer

Dear Friend, thank you for your inquiry. Several species of mites (Aceria) live on oak trees and cause similar symptoms. Based on the oak species and location, I assume it could be Aceria ilicis. Best regards, M. Zúbrik

Question

Answer

Hello,this type of damage is caused by species of the genus Tomicus. It is either Tomicus piniperda or Tomicus minor. The beetles are similar. They damage the twigs with their maturation feeding. The larvae live under the bark of dying or damaged (broken) pine trees. Removal or burning of dying and damaged pine trees is used as protection. Best regards Jozef Vakula

Question

Dobrý deň. Je možné strom zachrániť? Postrek, hnojivo… Treba viac napadnuté konáre zrezať? Ak sú fotky nedostatočné na určenie škodcu, viem spraviť detailnejšie, prípadne zrezať konáre a spraviť fotku. Vopred ďakujem. Maudra

Answer

Dobrý deň, ide o sypavku, ktorá napáda "len" staršie ihlice, ale pri silnej infekcii môže postúpiť a napádať aj mladšie ročníky, až bude borovica po niekoľkých rokoch bez ihlíc. Myslím, že pôvodcom je Mycosphaerella daernessii. v tomto období vyhrabať ihlice spod stromov spolu s opadanými šiškami a buď zakopať, zakompostovať alebo spáliť. Niekedy od začiatku júna v 2 týždňových intervaloch striekať kontaktným fungicídnym roztokom napadnutý strom. Striekať zelené ihlice, aby boli fungicídom ochránené pred vznikom infekcie. Ošetrovať do konca augusta. Po cca 2 rokoch by zdroj infekcie mohol byť odstránený a strom bude zdravý a zelený. Nie je nevyhnutné, že ak striekať a vyhrabávať nebudete, že strom odumrie. Viem, že strom je vysoký a asi sa striekanie nebude dať realizovať. Vtedy aspon vyhrabávajte ihlice a šišky a likvidujte ich. je to zdroj infekcie. Majte sa. Andrej Kunca

Question

Äter på rosenblad och vissa nävor

Answer

Thank you for your inquiry. The image shows an insect larva from the order Hymenoptera, specifically from the suborder Symphyta – commonly known as sawflies. The larvae of these species feed on rose leaves, and in Europe, several similar species inhabit rose plants. They cause defoliation, which reduces the plant vitality and aesthetic value. The image is somewhat unclear, so we cannot confidently identify the exact species. It could potentially be the larva of Endelomyia aethiops. With best regards M. Zubrik
