Question

S pozdravom Marián

Answer

Na obrázku je miesto,kde žila larva malého motýla. Phyllonorycter maestingella je malý nočný motýľ, ktorého larvy sú známe tým, že vytvárajú podlhovasté míny na listoch bukov (Fagus spp.). Samička Phyllonorycter maestingella kladie vajíčka na spodnú stranu bukových listov, vždy blízko bočnej žilky. Mína larvy začína ako podlhovastá škvrna, približne 5-7 mm dlhá, pozdĺž žilky. Ako mína rastie, mení sa na dlhú štruktúru na spodnej strane listu, typicky takmer vždy medzi dvoma bočnými žilkami. Larva žije a kuklí sa v míne. Mína je viditeľná aj na vrchnej strane listu ako svetlá škvrna. Nie je to významný škodca, ale často sa vyskytuje a môže lokálne znížiť estetickú hodnotu stromov najmä v parkoch a záhradách.

Answer

Dobrý deň,  uschýnanie tují môže mať viacero príčin. Podľa vášho  popisu  môžeme vylúčiť  sucho, nedostatok horčíka, nevhodné stanovište. Podľa príznakov najpravdepodobnejšou príčinou uschýnania  je lykokaz tujový, alebo lykokaz borievkový  Obaja spôsobujú rovnaké škody, a aj ich prítomnosť na rastlinách má rovnaké prejavy. Lykokaz borievkový aj lykokaz tujový sú invazívne škodce, ktoré sa u nás v posledných rokoch značne rozšírili. Vyhovuje im suché a teplé počasie. Vtedy dochádza k premnoženiu. Voľným okom ich spozorujete len ťažko. Lykokazy patria do čeľade podkôrnikovitých, pričom škodia nielen larvy, ale aj dospelé chrobáky. Sú veľmi malé (1,5 až 3 mm) a v našich podmienkach mávajú počas roka jednu generáciu. Prezimované dospelé lykokyzy sa začínajú rojiť keď teplota vystúpi nad 20 °C. O odoch druhoch si viac prečítate tu https://www.skodcoviadrevin.sk/skodca/lykokaz-tujovy https://www.skodcoviadrevin.sk/skodca/lykokaz-borievkovy   Pekný deň.    V. Longauerová

Question

Answer

Dear Gio, thank you for your request and picture. Cherry leaf spot (Blumeriella jaapii) is an important disease in Europe and America. Bird cherry (Prunus avium) causes the greatest damage. Other host plants include cherry (Prunus cerasus), common apricot (Prunus armeniaca) and common peach (Prunus persica). The pathogen mainly attacks the leaf blades, but exceptionally it can also attack the stems and fruits. Symptoms and harmfulnessParadoxically, unlike many other pathogens, cherry leaf spot primarily attacks older leaves. On the upper side of the leaf blade, distinctly red round spots of 1-2 mm in size are formed. On the underside of the leaf blade, smaller, sharply demarcated reddish-brown to dark brown spots are formed. They are covered with a fine coating of conidia. The spots on the lower and upper side of the leaf blade gradually become necrotic. The leaves gradually turn yellow, deform and subsequently fall. When fruits are attacked, significantly darker, sharply demarcated spots appear on the fruits. Infested fruits are usually deformed. The damage consists in the premature fall of the leaves, which reduces the photosynthetic activity of the tree. Trees have weaker growth, they are susceptible to environmental stress factors such as winter frosts or significant periods of drought. The pathogen results in a qualitative and, in particular, a quantitative reduction of the harvest. Spotting causes a huge problem in fruit nurseries or young plantings, where it slows growth and delays the fruiting period. Development cycleThe pathogen overwinters on fallen leaves, from which the infection spreads in the spring in the form of ascospores. Ascospores are able to infect leaves, stems and fruits in the period of 3-4 weeks after flowering of cherries. The leaves are infected through the stomata and the first symptoms can be observed 2 weeks after infection. Depending on the weather, they are released into the environment for 4-5 weeks. In addition to ascospore infection, conidia are the source of primary and secondary infection in many cases. Wet and rainy weather significantly promotes infection pressure. Infection can only occur if the leaf is wet. In the case of temperature, the optimum conditions for germination are in the range of 15-25 °C. ProtectionThe basis of protection is, first of all, the selection of habitat, variety, and cultivation form. It is important to avoid cold and damp locations, where the conditions for the development of mottledness are optimal. Ensuring an airy and non-compacted crown is important from the point of view of shortening the time of wetness of the leaves and thus preventing the germination of ascospores and conidia. Similar to the case of apple scab, it is also advisable to dispose of the fallen leaves and thereby significantly reduce the infection pressure in the following growing season. In the case of optimal weather conditions for the spread of the pathogen, it is advisable to carry out protection with fungicidal preparations 3-4 weeks after flowering. Preparations that contain the active substances mancozeb, fluopyram+trebuconazole, boscalid+paraclostrobin, dithianone have proven to be suitable. This treatment should be repeated after 10 days. If there is a long dry period during this period, there is no need to apply fungicides. With best regards,  Valeria
