"Minimum pruning", "minimal pruning" and "physiological pruning" as new techniques in grey mould agronomic eco-compatible (natural) control. Researches and considerations.
The aim of this work was to find agronomic eco-compatible ("natural") control solutions against grey mould of grapevine too. Our researches about "minimum pruning", "minimal pruning" and "physiological pruning" started in 1980, and in 1983 with specific relation to grey mould on vines of Merlot, Cabernet sauvignon and Chardonnay previously set in vegetative and productive growth balance. These researches were conducted to verify the affordability of innovative winter pruning techniques like "minimum pruning", "minimal pruning" and the so called 'physiological pruning", in the natural agronomic eco-compatible grey mould control. As a result we found that the new techniques contribute to limit the incidence of grey mould; especially "physiological pruning" followed by "minimal pruning" and 'minimum pruning". The best results were observed on Chardonnay, followed by Merlot and Cabernet sauvignon.
