Use of Aerated Compost Teas as a Preventative Foliar Fungicide on Grape Vines Vitus vinifera

Summary

There is substantial scientific literature as well as practical agri-industry applications showing the positive effects of controlling powdery mildew in grapes with compost teas. This project will attempt to identify whether aerated compost teas made from winery waste products and animal manure can be an effective pest management tool, at what concentrations they achieve control, what effect they have on the soil biosphere within the treatment area, and what, if any, effects these teas have on vine physiology and wine quality.
