What was the reason for the grape phylloxera devastation and why is there no solution?
Phylloxera is tiny aphids or louse that feeds on and feeds on the seeds of grapes. It can infest a winery by gnawing at the soles of workers’ boots, or by spread from vineyard to vineyard due to the proximity.
A brief history of phylloxera
A plague erupted across Europe which nearly completely destroyed all wineries around the globe. In the last quarter of the 1800’s wineries across Europe were ravaged and destroyed their families’ ancient vineyards in an attempt to stop the spread of diseases.
In the early 1900s, Phylloxera took a staggering death toll. More than 70% of vineyards in France were gone – the livelihoods that thousands of family members were destroyed. Then the world plunged into a world-wide wine deficit.
In one instance three tiny parcels of Pinot Noir belonging to Bollinger in Champagne mysteriously stood up to the pressure. The result was 3000 bottles of wine, dubbed “Vieille Vignes Francaises” (French Old Vines) were the most sought-after Champagne bottles.
An Bounty for the Cure
In a state of shock The Minister of Agriculture and Commerce in France provided 20,000 Francs, or $1 million today – to anyone who can find a cure.
Where did Phylloxera originate?
It’s a shame, but it’s out of America! United States! Here’s where things begin to become interesting:
Sad tail the sad tale of Agoston Haraszthy
Phylloxera might have spread via the inadvertent activities that were taken by “Count” Agoston Haraszthy, the person who founded Sonoma’s most famous winery, Buena Vista Winery in 1857.
It was 1861 when Haraszthy went to Europe exploring the vineyards in France, Germany and Switzerland to take samples. He returned with cuttings of 350 varieties of grapes. He also established an experiment in Sonoma.
The vines were tragically turned brown and died, marking the first outbreak in Phylloxera throughout the U.S.. After much disappointment, Agoston Haraszthy filed for bankruptcy and moved out of his home in the U.S., never to come back.
Researchers of the past put in a lot of effort to comprehend the tiny louse.
The Genus Phylloxera is distinguished by having three-jointed antennae. the third one being the longest, as well as the wings that are flat on its back instead of the roof-style. It is part of all-winged insects (Homoptera) and is divided between two major families in that sub-order: that of the plant-lice (Aphididae) on one hand, and the bark-lice {occidae) in the opposite. The tarsus with one joint of the newly-hatched louse or larva and being oviparous, it displays affinity with the second family However, in the tarsus with two joints of those who are more mature, and in every other character it is mostly an aphididan.

The Reward Wasn’t Paid!
More than 450 articles were published on the subject Phylloxera during the period of 1868-1871. Research was conducted using testing plants as well as poison, flooding and grape breeding methods and more.
An independent team of researchers that included one Frenchman, Jules Emile Planchon as well as one American, Charles Valentine Riley found an answer! The process of grafting the vitis vinifera (the European grapevine) onto American root stock stopped root-eating louse.
The original researchers had not wanted the money that grew to almost $5 million of today’s dollars A viticulturist in Bordeaux known as Leo Laliman did. Laliman had taken the experiment methods and made them an industry practice in Bordeaux. The government rejected him and claimed that he’d just employed preventive measures but did not develop the cure.
Europe Wine Grapes that have American Roots
Today, rootstock is still employed in a large portion of the world’s wine, and phylloxera is in danger.
The threat is not less than in U.S. In the 1990’s , a variant of Phylloxera known as “Biotype B,” was discovered to be thriving in AXr1 which was a popular rootstock. Around two-thirds of vineyards in Napa in the 1990’s were planted. Phylloxera has also decimated the ungrafted vineyards of Oregon and its owners thought that the louse would not overrun the fertile soils.
Phylloxera Resistant Vineyards
There have been a number of instances in which vineyards were not affected due to grape phylloxera. Although many of these areas remain a mystery but a large portion of the vineyards with phylloxera resistance are located in areas that experience strong winds.
Within Australia, Queensland was infected by the disease in the 1870s. The Australian government responded to protect their vineyards by enacting the Vine Protection Act of 1874 that ended the usual practice of transporting grapes machinery and other equipment across the state. In the present, Tasmania and Western Australia have not yet been infested.
