Diseases and pests of hazel

Lijeska je voćna kultura koja proteklih godina doživljava sve veći porast proizvodnje. Širenjem površina pod nasadima lijeske dolazi do sve većeg širenja bolesti i štetnika koji napadaju stabla lijeske. Cilj završnog rada je bio pomoću stručne literature predstaviti i opisati biologiju i simptome najznačajnijih bolesti i štetnika lijeske te utvrditi njihovu pojavu na vlastitom gospodarstvu. Vlastito obiteljsko poljoprivredno gospodarstvo ne podliježe jačim oboljenjima i napadima štetočinja, ali je tijekom godina ustaljeno njihovo pojavljivanje. Pravilna primjena sredstava za zaštitu bilja uz pravovremene preventivne mjere zaštite doprinose kontroli zaraze bolestima i napadu štetnika. Zaštitu treba provoditi u skladu s naputcima od strane stručnjaka kako nebi došlo do većih ekonomskih gubitaka u proizvodnji lješnjaka.Hazelnut is a fruit crop that has experienced production increase in recent years. The spread of the area below the hazelnut plantations leads to an increasing spread of diseases and pests attacking the hazelnut trees. The aim of the final paper is to present and describe the biology and symptoms of the most significant diseases and pests of hazelnut by using professional literature and record them on own family farm. Own family farming is not subject to severe diseases and pest attacks, but has been a regular occurrence over the years. Proper application of plant protection products with timely controlled occurrence contributes to the fight against disease and pest infestation. Plantation protection and monitoring should be carried out on a calendar basis in order to avoid large economic losses in hazelnut production
