Possibilities of Strawberry Integrated Disease and Insect Pest Management in Different Production System

In the last few years strawberry production in Croatia is constantly increasing. One of the main problems in production are diseases. During two-years trials in stawberry plantations in northern Croatia, the occurence of diseases was monitored in order to establish the most effective methods of integrated disease management. Trials were performed in three different production systems: open field, greenhouse and hydroponic system production. The most frequent disaease in all three production systems was gray mould (Botrytis cinerea). In open field production, the occurence of common leaf spot (Mycosphaerella fragariae) and leaf scorch (Diplocarpon earliana) were also frequently observed, while leaf blotch (Gnomonia comari), leaf blight (Phomopsis obscurans) and fruit antrachnose (Colletotrichum spp.) were only sporadically present. For the control of the most important disease, gray mould, forecast model BOTMAN was implemented. As relatively simple model based on meterological data, BOTMAN allowed effective, ecologically and economically more acceptable control, based on integrated chemical and biological measures. Meterological data were were obtained from State Hidrometerological Department (DHMZ). Resuls showed no significant difference in intensity of gray mould infection between usual chemical control and BOTMAN-based control. Two-years research on strawberry disease management in Croatia revealed perspective possibilites of integrated strawberry disease management.
