THE DYNAMICS OF THE BROWN ROT ATTACK - MONILINIA FUCTIGENA (HONEY), IN THE APPLE ORCHARDS IN SIBIU- DURING 2007 – 2009 PUBLISHEDAna Timar
I’ ve been noticing the dynamics of the pest agent Monilinia fructigena Honey on the apple culture from 2006 up to 2008, in the pedoclimatic conditions of Sibiu. The observations were made both during the vegetative growing and dormant period of the culture on: knowing the fungus biology, the biological reserve of the pest agent, the level of the attack, the establishment of the optimum moment and the opportunity to apply the phyto-sanitary treatments, the legal products for the protection of plants that were used on the teritory of the county in the studied years , the apple areas affected by. The reaserch in this domain must be permanently made. The methods and the materials, that were used, are both clasical and modern, made in the context of the the persistant growth of the agro systems of the apple orchards and can lead to very modern research on the quality of the crop, and to the residues of the chemical substances in the fruit, according to the present law- Comes I., Lazăr A., Drăcea A,Bobeş I., Hatman M.- (1977), N. Minoiu (1980), Tănase C., Şesan E.T. (2006), Pârvu M. (2003), Iacomi B., Vlad F.F. (2006), the Ministry of Agriculture and Rural Developpment-(Pesticides residues in plants and vegetals). The practical implications of the research, made by annual observation of the dynamics of the brown rot attack in the apple orchards in Sibiu, led to the issues of the warning systems for an integrated combat against the pest agents, in order to implement a system for applying the plant protection products that fight against the fungus pest agents, according to the communitary standards. Knowing the dynamics of the attacks on the Monilinia fructigena Honey fungus in the apple orchards in Sibiu, the most adecquate protective measures, made in the context of a long lasting development of the horticultural agroecosystems ,can be scientifically.
