CONTRIBUTIONS TO THE SETTING UP OF THE SYSTEM FOR INTEGRATED CONTROL OVER THE PATHOGEN MYCOTIC AGENTS IN THE APPLE CULTURE, FROM SIBIU COUNTY PUBLISHED

Ana Timar
The monitorisation of the pest agents, that are specific to the apple crop in Sibiu during 2006-2008, was meant to establish the annual strategies to the integrated defeat- the integrated menagement- of the fungus pest agents of the apple crop, keeping them under the limit of the economic level of the pest and the protection of the natural predator wildlife. The research was made every year through surface surveys, by samples of the organic plants having symptoms of an attack , in order to inventory the fungus pest agents, the imminent attack, and taking the decision to apply the phytosanitary treatments of the optimum moment. The analysis of the samples picked up from the ground was macroscopically and microcospically made Constantinescu (1974). The integrated combat is meant to have a permanent adaptation of the combat working systems to the ecological conditions of every microarea. That’ s why, the combat systems must be corrected in accordance to the prognosis, warning, economical pest level, correlated to the entomophagus density, the presence or the lack of the selected pesticides. The research are both classical and modern, using as the modern warning methods of chemical treatment electronics, communications and informational systems Şuta V. (1980), Minoiu N. (1980) Comes I., Lazăr A., Drăcea A,Bobeş I., Hatman M.(1977), Minoiu N. (1980), Tănase C., Şesan E.T. (2006), Pârvu M. (2003), Iacomi B., Vlad F.F. (2006), Isac I. (2002), Sistemul AgroExpert. Knowing the fungus pest agents kinds that are present in the apple orchards, the assessment of their attack ,there are programs of phytosanitary treatment made in an integrated combat system of the pest agents in the microareas and in individual orchards.So there ca be applied the combat measures that are based on the mixture of the agrotechnical, physical, biological and chemical methods in the context of the offered agrosystem, only if it’s economically justified.
