Grape Compass | Enabling Quality Grapes

Powdery mildew, Downy mildew and Botrytis bunch rot are constant battles for grape growers. Once identified in vineyards, it can do great damage to fruit quality and quantity. Chemical fungicides are applied preventively to mitigate this risk, usually scheduled irrespective of actual disease pressure levels. This approach results in overdosing, environmental pollution and unnecessary costs of chemicals and labour.

Grape Compass provides reliable forecasts of fungal disease pressure risks for the coming five days. This allows farmers to only spray for Powdery mildew, Downy mildew and Botrytis bunch rot when needed and reduce unnecessary expenses.

Grape Compass is developed together with several high-profile wineries in the South African Western Cape and Spain.

“The powdery mildew is always a problem, but with the timely warning on downy mildew, the app helps in deciding if we are going to use a contact or systemic chemical against the fungal infection.”
Gerhard Crous, Oukraalsvlei
“The application is accurate. The app makes positive contribution and helps with the decision-making process.”
Arjen Rijpstra, Dornier Wines
“Grape Compass is like having an extra person monitoring the vineyards, working all day, seven days a week. It gives a full infection risk report daily and by providing a forecast for the next couple of days, the app is extremely helpful with decision-making and adjusting the spray program accordingly.”
Johan Montgomery, Hamilton Russell Vineyards
“I think the biggest benefit is to see a few days in advance what the disease pressure will be and make additional changes to your spray program.”
Francois Viljoen, Protea Heights Farms
“Simple to use and good information. Good to know the disease pressure during the season.”
Nichola Bruyns, UniWines
