“We sprayed for suppression of powdery mildew using compost tea from our Growing Solutions System500. By anyone’s measure, a huge success.”

Compost Tea has shown promise in combating common vine diseases such as powdery mildew and botrytis. Foliar application of Compost Tea provides vast numbers of diverse microorganisms that function as a biological shield to prevent these diseases from reaching devastating levels, effectively reducing the need for fungicides.
Improved flavor and characteristics
The level of microbial activity in vineyard soil is an important yet often overlooked element in the terroir of wine. The biological boost provided by Compost Tea as well as the micronutrients it provides are both key in developing flavor complexity.
New and replant survivability
Applying Compost Tea on new and replanted vines stimulates their immune system and promotes healthy root development at this critical stage of plant establishment.
“In 2008, at Benziger Family Winery, we took one of our best blocks—four acres of Cabernet Sauvignon—and sprayed for suppression of powdery mildew using Compost Tea. Mildew pressure, using the Doug Gubler model on an Adcon weather monitoring system, was rated as high (60–100) for 16 consecutive days in May, 22 days in June, and 17 days in July. On July 14 we noticed the beginning of powdery mildew on about 50 vines, less than one percent of the block (5,445 total vines). We cleaned the vines and had no further problem for the remainder of the season. I believe we achieved our goal due to a ‘systems’ approach—producing tea in our Growing Solutions System500, utilizing their Compost Tea Catalyst, and the use of high quality vermicompost from Sonoma Valley Worm Farm.”
