Promising results of the Biocontrol-Grapevine application despite a very strong “downy mildew year\u201d<\/strong><\/h2>\n<\/div><\/div><\/div>\n\n

Chassieu (France), July 29<\/strong>th<\/strong>, 2021 – 5:45 p.m. – AMO\u00c9BA (FR0011051598 – ALMIB)<\/strong>, producer of a biological biocide capable of eliminating bacterial risk in water and human wounds, and of a biocontrol product for plant protection, still in the development phase, announces the results of the third field trial campaign against grapevine downy mildew and powdery mildew of its biocontrol solution, in a very strong mildew year<\/p>\n<\/div><\/div><\/div>\n\n

\n

A difficult meteorological context very favourable to downy mildew.<\/strong><\/p>\n<\/div><\/div><\/div>\n\n

\n

In France, after heavy frosts in April, May was relatively cold and the few rains did not cause any contamination.<\/p>\n<\/div><\/div><\/div>\n\n

\n

A rise in temperatures was observed in June until a short period of heat wave. From 10-15 June, episodes of heavy rain followed one another, causing sudden and very important contaminations on leaves and bunches in many regions: Bordeaux, South-West more generally, Champagne, East, as well as Burgundy and Beaujolais to a lesser extent.<\/p>\n<\/div><\/div><\/div>\n\n

\n

Thus, significant and sometimes unprecedented damage was observed in these different regions.<\/p>\n<\/div><\/div><\/div>\n\n

\n

Faced with these exceptional disease pressure conditions, even the products considered to be the most effective against downy mildew were put to the test. Copper (Bordeaux mixture), at its full rate of 750 g\/ha per application, applied every 7 days, was regularly ineffective, showing only insufficient protection in many trials, contrary to what was observed in previous years.<\/p>\n<\/div><\/div><\/div>\n\n

\n

Nevertheless, such conditions are favourable for testing products under development.<\/p>\n<\/div><\/div><\/div>\n\n
