IMPACT OF AMPELOTECHNICAL MEASURES IN THE GRAPEVINE PROTECTION FROM OCCURRENCE OF GREY MOULD (Botrytis cinerea)

Abstract

Grey mould (Botrytis cinerea) provokes severe damages and yield loses in grapevine (Vitis vinifera). This research determined ampelotechnical mesaures can be used to influence the development of the  disease  by reducing the number of chemical treatments. The black grapevine variety Vranec was continuously observed in the experimental field located at Kraiste, Kavadarci, Republic of Macedonia. The working hypothesis was to follow the development of the disease 14 days after the last treatment, when the impact of the fungicide decreases and by applying agrotechnical measures and green operations to control the development of the disease. Those variants where there was a reduction of irrigation and which they were applied ampelotechnical measures was significantly lower intensity of infection in relation of control.
