PRECISION PATHOGEN CONTROL

Real-time Pathogen Alerts 

 The information you need without more tools to learn or more work to do. Our fully automated, in-field sensors can send pathogen alerts directly to your phone or upload automatically to the dashboard you already use.

2021 GRAPEVINE POWDERY MILDEW PILOTS

Brad Saved $34,000

Brad decided to lengthen his sprays because of our data showing that there was no powdery mildew in spring 2021. We didn't see any powdery mildew at any of Brad's five sensors until June 22, months after he began spraying. He lengthened the intervals between sprays from 8 to 14 days starting in May, cutting two sprays and saving $34,000. In addition, he was alerted when and where powdery mildew was present so that he could stay on control efforts at just the right time. Brad and his team first saw powdery mildew on July 7, more than two weeks after we first alerted him to the spores entering the vineyard. We also alerted Brad later in July to high pathogen pressure at only one of his sensors, which he confirmed was coming from a neighbor's vineyard.

Caleb Reduced to Only Three Sprays All Season

Caleb had one of our sensors in a vineyard in Napa. Caleb started spraying much later than usual because our data showed that there was no powdery mildew. He also lengthened his sprays to every 21 days and stopped spraying altogether before powdery mildew first appeared in late July. He only sprayed three times in 2021 and never had symptoms until the end of July.

Kyle's Alert Comes Weeks Before Symptoms And Weeks After Historical Expectation

Kyle had three sensors in the Santa Cruz mountains, including one at a site that gets powdery mildew every year. The particular site is especially hard to spray  as it is on a steep hillside. Historically, powdery mildew pressure is high even in the early season at this site, but our sensors showed that this year there was no powdery mildew until much later than expected. Our sensors detected powdery mildew's first arrival on June 8, and Kyle first detected symptoms on July 6.

It's time to move on from the Powdery Mildew Risk Index

Powdery mildew remains one of the world's most severe and persistent threats to grape production, with viticulturists using more chemicals to control this disease than any other vineyard problem. Traditionally, fungicide applications are timed according to the Powdery Mildew Risk Index (PMI). However, the PMI leads to over-applicating fungicides when disease pressure is low. Unlike the PMI, Root's technology allows growers to monitor disease pressure and accurately assess when and where interventions are needed.
