In trials that began in the lab, then moved onto potted vines, small plot trials
and finally grower based trials, the use of Calcium reduced the botrytis levels 
significantly.
 “We used BIOMIN Calcium and put three applications on. Some growers
only put two on, although our early research had shown that four would be the best.“
Basically they were applied at 14-day intervals and the average reduction across
these blocks was about 48 per cent. Read original article in NZ Winegrowers Magazine
