Are you planning to plant new vines in your vineyard? Here we have a new success case perfect for you. WineSeq® can help you make sure the vines are healthy and confirm the absence of pathogens. This is very important in order to make a proper plantation and avoid future economic losses.



A vine-grower with a forty-five acre vineyard in California wants to plant twelve new acres of Chardonnay.


The study

The vine-grower purchased vines from a nursery at his local market. He wanted to confirm the absence of pathogens in the acquired plant material prior to developing the new Chardonnay new vineyard. The vine-grower selected two different rootstocks.

We implement a protocol from the WineSeq® test to determine the microbial population of the plant lots defined. Starting with plant material packed in bundles of 25 vines located in a cool and humid place, we selected five plants from different bundles arbitrarily for each combination of rootstock.

The conclusion

A WineSeq® test was conducted with the sample plant material to detect the active microbial community. The results showed the presence of pathogens associated with diseases of wood and root at 27%. The pathogenic fungi found corresponded to Petri disease, Phomopsis viticola and root diseases such as Cylindricarpon spp.

This illustrates the importance of microbiological analysis of plant material prior to planting a vineyard. Hefty economic losses can result if an assessment of the sanitary status of the plants is not made. In this case, WineSeq® successfully diagnosed pathogens prior to planting and a loss of $100,000 was avoided.
