EFFICACY OF SOME TREATMENTS ON MONILINIA FRUCTIGENA (ADERH. & RUHL.) HONEY FUNGUS ATTACK ON APPLE
The researches were carried out in the experiments on the attack of Moniliniafructigena on apple in the Hartiesti location, Arges county. The evolution of the pathogen attack in the years 2015 and 2016 was monitored, in control variants and in variants treated with specific fungicides, included in a treatment scheme. The microscopic examination of the morphology of the pathogen corresponded to the fungus Moniliniafructigena. The biological material was Florina, Generos, Goldrush, Idared and Topaz varieties. In the conditions of year 2015, Moniliniafructigena's attack recorded values between 18.5% for Florina, 21% for Generos, 34% for Idared and 29.5% for Topaz. In the year 2016 the control variants of the fungus attack was 22% for the Florina variety and 36.5% for the Idared variety. The application of a treatment scheme that included specific products for the control like DithaneNeotec 0.2%, Topsin 0.07% and Switch 62.5WG 0.066% which had an efficacy of more than 66% in 2015 and 68% in the year 2016. In the varieties Florina and Topaz it have been calculated the highest efficacy values of over 70% during the experimentation period. Generos and Idared varieties recorded relatively close values of the efficacy of moniliosis treatments, ranging from 66.6% to 67.6% in 2015 and 69.4% respectively and 68.5% in the year 2016. The Florina variety was noted throughout the research period with the highest efficacy value E = 70.2% in 2015 and 77.25 in 2016.
