Most vineyards reach for sprays when insects appear. Near Stellenbosch, Vergenoegd Löw sends ducks.
Roughly 890 Indian Runner birds clear pests as they waddle between the vines. Hundreds of hatchlings are expected each season. When grapes near harvest, the flock moves to irrigation dams so droppings feed fertigation — liquid fertiliser through the water system — instead of landing on fruit. Sheep and cattle round out the regenerative cast. Neighbouring farms have started buying birds of their own. The picture is catching on because it is visible, countable, and easy to explain to visitors.
Mini-concept: pest pressure as ecology. Chemistry still has a place in farming. It is not the only tool. A living flock turns insect control into a daily walk and turns waste into soil food. For drinkers choosing wine with an intentional story over a nameless industrial pour, the ducks are the memorable pattern: fewer sprays, more biology between the rows.
Remember one number and one move. About 890 ducks on patrol — and a harvest-time walk to the dams so the fruit stays clean while the land still gets fed.
