D. (%) = Attack degree; 2 E (%) = Efficacy of treatment with fungicides. The varieties Anna Späth and d’Agen had approximately a similar response to Monilinia laxa in 2010 in the variants treated with fungicides (85.1% respectively 85.4% efficacy). Efficacy for prevention of Monilinialaxa attack, ranged in the year 2010, at the first variant of phytosanitary treatments, from 85.1% (the variety Anna Späth) to 87.3%. (the variety Stanley). In the second variant, in the same year, the efficacy of treatments in the vegetation of plum against pathogen Monilinia laxa ranged from 83.3% (the variety Anna Späth) to 86.1%. (the variety Record). The highest value of efficacy were recorded in the third variant, ranging from 91.5% (the variety Stanley) to 100.0% (the variety Record). In 2011, the efficacy of treatment varied in variant V1 between 87.2% (the variety d'Agen) and 92.9% (the variety Record) in variant V2 between 84.6% and 89.3% for those varieties and in the variant V3 between 92.7% (the variety Stanley) and 100.0% to Record variety. In 2012, it was the least favorable climatic for pathogen Monilinia laxa were recorded following variations efficacy of treatments: in V1 from 79.2% (the variety Stanley) to 85.7% (the variety Tuleu timpuriu); In V2 were recorded the same values to the same variety, 335 respectively 79.2% (the variety Stanley) and 85.7% (the variety Tuleu timpuriu) Should be noted that the application of systemic fungicides in the ripe fruit phenophase played an important role in protecting the fruit when rainfall occurred until the harvest. CONCLUSIONS Monilia disease, brown rot of fruit or plum mummification, is a widespread disease of plum growing in all countries and may cause serious damage by destroying flowers and fruit. The range of Monilinia laxa attack in plum tree is highly variable each year. The variety Record showed the lowest attack degree of the pathogen Monilinia laxa. In all variants with different combinations of fungicides applied were recorded very good values of efficacy of phytosanitary treatments during the growing season. In the three years of research, the highest values of efficacy treatments we recorded for the third variant of treatment, with fungicides Bravo 500 SC, Signum FG and Merpan 80 WDG.
The best values of efficacy treatments are recorded at the year with average pressure in the attacking pathogen Monilinia laxa in plum. Treatments is fully justified especially in a highly favorable climatic year (with many precipitation and heat) for Monilia disease, as it was in 2010.
