Cré Dóchas offers Vine Disease

Could the response be one of the worst problems associated with the fishery involving the simple application of kaolin?

Wouldn't it be great if the answer was one of the worst danger problems the United States had was dusting clay?

Spoiler Alert: Pierce Disease could be more complicated than that. In California, however, Ridge Vineyards is discovering that disposal of kaolin clay could be an adequate barrier to acute green lockers to consider the seven acres of Chardonnay to replant which it lost for Pierce.

The insects do not like the white color of the clay and, if they want to feed on the eyes of treated vines, that is how they spread the t Xylella fastidiosa bacteria, "they get clay mouth, and they say they are", says Eric Baugher, CEO and wine maker, with some satisfaction. But it is as transparent and transparent that it does not appear to affect photosynthesis.

The spray maker, known as Nacht, says that even if the vines keep cooling on the spray, photosynthesis can continue on hot days when the vine would otherwise close. Sounds like a win-win?

In California, rather than in many other states, the best vector of the disease is the blue-green vector, which is a weaker advertisement than the heavy glass of glass that extends energetically elsewhere Pierce. . However, Baugher said, "No one was successful".

The worst drought years were; the sharpshooters left the forest because their habitat was dying, and the seven acres of Chardonnay Ridge were close to the forest edge. Warm winter encouraged their numbers as well and, says Baugher, they love Chardonnay's soft leaves: "They are like candy."

Bordeaux Ridge types, which have more intense leaves, are higher and further away from the forest, so only Chardonnay is affected. Ridge is making only half as much Chardonnay today as a result, says Baugher.

Kaolin is cheap, and does not affect photosynthesis – but in the drought years, Baugher says, it was not helpful. So it's not a perfect answer. At the end of the drought, and with January and February cold, wet behind them, replanting is now feasible.

It can help to prevent the distance between forest and vines, and by removing the host host plants. However, there are more than 170 of these, and they also include plants such as hare and BlackBerry.

But can vines, when they are infected, never come back? Research has revealed UC Riverside suggests that it is possible. The earlier the year with infected vines the chances are that she will die; Infected vines in June usually receive the following winter, although it is not clear why. Best winter cold than winter ones for recovery.

One day soon there might be another answer there. Ridge is involved in field trials of bacteriophage treatments which aim to cure infected vines rather than prevent infection. The phage is a virus that attacks bacteria) that kills the bacteria in the plant's xylum vessels. Are there any side effects? So far.

The field trials of Chardonnay at Monte Bello and Zinfandel are at Lytton Springs, and are the latest stage in a much longer project. They started at Texas A&M University in a laboratory setting about 10 years ago, and moved out into actual vineyards about five years ago. A few years ago Ridge was partial. By then the dosing and injection method had been determined, and Ridge started testing it on vines showing signs.

Of course, they were not able to use the fruit from vines in the test for commercial wine, but Baugher believes that the system is effective, does not change the quality of fruit in wine making, and that there is no risk that the fermentation survives and enter the wine. "It will be commercialized at some point," he says.

In exchange for the most common control methods, neonicotinoids spray against acute substances – neonicotinoids were caught with a bee-honey colony collapse – hope is being offered by bacteriophages; and meanwhile a spray of clay could also help.

Good news for vines, and good news for bees too.
