Integrated Pest Management

Rutherford and Dollarhide vineyards are planted to cover crops between the vine rows, to harbor beneficial insects, compete with weeds, add essential nutrients to the soil and limit erosion. The leaf canopies are managed to host beneficials balancing the threat of pests. Integrated Pest Management is utilized throughout as an effective and environmentally sensitive approach to managing unwanted pests.

All organic solids from the winemaking process are composted back to the vineyard. Reduced and no till systems have increased, reducing emissions and preventing erosion. Additionally, St. Supéry’s carbon studies indicate both vineyard properties sequester +1400 metric tons/year.
