PROTECTION APPLES DISEASE AND PEST ON OPG - in PRIMORAC in 2014 . YEAR

Jabuka je drvenasta biljna kultura iz porodice Rosaceae. Cvatnja jabuke započinje u travnju, a dozrijevanje ovisi o sorti. Cilj ovog rada bio je utvrditi štetnike i bolesti koji se javljaju na jabuci u 2014. godini na OPG - u Primorac u VoĎincima, te poduzimanje odgovarajućih mjere zaštite u skladu s propisima integrirane zaštite bilja kako bi se osigurao što veći prinos uz što bolju kvalitetu ploda. Najveći problem uzgoja jabuke u 2014. godini su bili vremenski uvjeti koji su bili pogodni za razvoj bolesti od kojih su najveće štete činile mrljavost lista i krastavost ploda (Venturia inaequalis) i pepelnica (Podosphaera leucotricha). Od štetnika u 2014. godini na OPG – u Primorac štete su zamijećene od: lisnih uši (Aphididae), lisnih minera, jabučnog savijača (Cydia pomonella), te crvenog voćnog pauka (Panonycus ulmi Koch). Kemijsko tretiranje za suzbijanje bolesti se vršilo 18 puta, a za suzbijanje štetnika 7 puta. Zbog dobrih vremenskih uvjeta za razvoj bolesti nije bilo mogućnosti za njihovo potpuno suzbijanje, te su one uvelike smanjile kvalitetu ploda, a suzbijanje štetnika je bilo uspješno zbog pravovremenog tretiranja i vremenskih uvjeta.Apple is a woody plant from the rose (Rosaceae) family. Its flowering begins in April and maturing depending on the variety. The aim of the study is to identify pests and diseases that occurred on apple trees on the family farm Primorac in VoĎinci during 2014 in order to take an appropriate protective measures in accordance with the regulations of integrated pest management aiming to ensure the maximum yield of quality fruit. The biggest hurdle of growing apples in 2014 were the weather conditions which were suitable for the development of many diseases. Most of damage was caused by Apple scab (Venturia inaequalis) and Powdery mildew (Podosphaera leucotricha). Observed pests damage was mostly caused by: Aphids (Aphididae), Leaf miners, Codling moth (Cydia pomonella), and Fruit tree red spider mite (Panonycus ulmi Koch). Chemical treatment for disease control was carried out 18 times and 7 times. For pest control, and due to good weather conditions for the development of the disease there was no possibility of their complete suppression, and hence the quality of the fruit was greatly reduced
