Now is the time for Liquid Lime Sulfur treatments

Liquid Lime Sulfur (calcium polysulfide) is used primarily as a dormant application to disinfect the cordons and canes just prior to bud break. Applying during the first 10 days of April in would be a good time-frame to get this done. Liquid lime sulfur is toxic to most forms of fungi. The overwintering innoculum of anthacnose, phomopsis and powdery mildew is in the bark crevices, canes and buds of the grape plant. Applying liquid lime sulfur just prior to bud break provides excellent control of anthracnose, good control of early season phomopsis and some control of powdery mildew. Reducing the amount of overwintering innoculum can dramatically reduce and delay the infection rate of these diseases as the new shoots and leaves emerge from the buds. Rain splash is the primary method of infection of these new tissues.

Most liquid lime sulfur labels (28-29% calcium polysulfide) recommend mixing anywhere from 2-20 gallons of liquid lime sulfur in 100 -200 gallons of water/acre and spraying with at least 100 psi of pressure. . Many vineyard operators will mix 1 gallon of liquid lime sulfur to 10 gallons of water and spray their recently pruned cordons and spurs or canes with a sprayer handgun. They typically will end up using only 2.5-3 gallons of liquid lime sulfur per acre when applying it in this fashion. Others are using only 1 to 2 nozzles of their air blast sprayer directed at the cordon. This normally requires higher amounts of liquid lime sulfur per acre because of the overspray that misses the

1 cordon. Liquid lime sulfur in 5 gallon jugs normally runs around $14 per gallon. Many forms of liquid lime sulfur are approved for organic grape production.

BSP Sulforix (27.5% polysulfide) is a liquid lime sulfur product that contains proprietary surfactants that BSP claims to have better spreading and retention than the common liquid lime sulfur products. Many commercial vineyards have been using this product instead of the typical liquid lime sulfur product. The Sulforix label recommends a rate 1 gallon of Sulforix per acre applied as a dormant application. Many growers are mixing around 1 gallon of Sulforix per 25 gallons of water and spraying through a handgun. BSP Sulforix costs approximately $25 per gallon in 2.5 gallon containers. BSP Sulforix is NOT approved for certified organic production.

These dormant applications can be applied to both sulfur tolerant and intolerant grape varieties prior to bud break. Good coverage on both sides of the cordon, arms, spurs and/or canes is required to be effective. Only sulfur tolerant grape varieties should be treated after bud break.

Example Liquid Lime Sulfur labels:

AllPro Liquid Lime Sulfur: http://www.valuegardens.com/allpro/labels/152360.pdf Rex Lime Sulfur: http://www.cdms.net/LDat/ld78A002.pdf BSP Lime Sulfur Solution: http://www.cdms.net/LDat/ld861006.pdf BSP Sulforix: http://www.bestsulfurproducts.com/label/sulforix.pdf

Note: Liquid lime sulfur is very corrosive. Suggest spraying spray vehicle with a light coating of PAM, diesel fuel or mineral oil to protect the paint and metal surfaces.

Wine by the numbers....

There are over 10,000 taste buds on an average person's tongue

It takes 650-850 crushed grapes to make a bottle of wine

Eighty five is the average number of grapes in a cluster of winegrapes.

Ohio is now home to over 145 wineries with more coming on board each year.

There is an Ohio winery within 45 minutes of nearly every resident's front door step.

“Appreciate your newsletter,

I am still a hobbyist at this time. Really appreciate your article on the Wollersheim Winery they have great wine and seem to be a good business model. Enjoy your piece on their history did not realize their depth into the wine industry.”

local parks, city officials say. Alternately

called the “chickow” or the “cowen,” the

animal “should be an immediate hit with

tourists.”

The city council approved the experiment

after being advised by the city attorney

that, although easily excitable like a

chicken, the lumbering clone would be too slow to attack annoying children. 5

“And as it produces both eggs and milk,” added one council member, “the Chickow will pay for itself with a booth at the Farmer’s Market.” Happy April Fool’s Day.

On Tuesday evening, 3-30-10 Zack Bott, winemaker at Fireside Winery asked that I come up and do a grape pruning demonstration for him and their employees along with anyone else who wanted to attend. Fireside covered all costs to provide this service. The demonstration was done at Bill and Rona Wyant’s vineyard just south of Marengo, Iowa. Bill and Rona are the primary owners of Fireside Winery, Zach’s in-laws and his wife Cassie’s parents. Cassie handles all the marketing for Fireside Winery. The entire family is involved with the winery and vineyard. The hands-on pruning demonstration started at 3pm and ended around 9 pm. (Yes, it got dark!) People arrived and left on their own schedules.

6 Notable Quotables

“The point is that wine is a fashion-driven business. Like other trendy, optional pleasures, wine is mostly viewed as entertainment. It must compete with everything else that's vying for consumers' entertainment dollar. Do you buy a $20 bottle of wine, or go to the movies with your spouse?”

--- Peter Gregutt from Wineries are tapping into eco-friendly trends, 3-27-10 – Seattle Times: http://seattletimes.nwsource.com/html/wineadviser/2011372192_pacificpadviser28.html

“Just one week after a California committee successfully voted against a nickel-a-drink tax, the state is already faced with another huge tax increase that has been cleared for circulation by the Secretary of State…” “If passed, it would raise taxes 4 cents to $5.11 on a 750ml bottle of wine; 11 cents to $6.08 on a six-pack of beer; and 65 cents to $17.57 on a 750ml bottle of spirits.”

--- 3-30-10, Sonoma Valley Sun

“Wine direct shipping continues to be a hot legislative issue even though the number of states that continue to prohibit winery shipments has dropped to 13. In fact, of the top 10 largest wine consumption states, discussions have been active in the three remaining states where direct shipments are not occurring: New Jersey (#5), Massachusetts (#7) and Pennsylvania (#10).”
