Do you detect anomalous behavior in the growth of your vines? The problem may be on the soil. The microbial community that lives in it can tell you more about its status than you think. Here we show you a real case of vineyards affected by Pierce’s disease. Performing WineSeq® tests we could discover the behavior of the microorganisms present in the soil and vines, and how could we limit the effects. Do you have the same problem? Check out how can we help you!


A selection of 25 vineyard plots located in the United States and Spain where Pierce’s disease thrives.

The study

We proposed a protocol to better understand the properties and behavior of Xylella fastidiosa, which is responsible for the development of Pierce’s Disease. WineSeq® also investigated the vectors that influence Pierce’s spread in order to assess impact and contribute to the search for a viable solution that limits its expansion.

The conclusion

We administered a WineSeq® test on vineyard soils and plants to detect the active microbial community. We found several Xylella fastidiosa focal points in five of the analyzed plots. The pathogen was in both the plant and the soil of the lower areas of the plots closest to the rivers. It is not usual to find this bacteria in soil since it is propagated by insects, mainly hemipteria of the subfamily Cicadellinae and the family Cercopidae.

We implemented measures to limit the fungus’ development although there are currently no known methods of curative control. The focal points were located in the plots and WineSeq® evaluation indicated isolating these areas as well as minimizing the accumulation of plant material from the perimeter. We also recommended the use of resistant clones and plants certified free of pathogens to further protect the affected vineyards.

If you want to save money on your vineyard do not hesitate to analyze the soil and vines.
