Pressure Control Valves Highly Recommended for Backpack Sprayers

Most, if not all commercial vineyard owners have a backpack sprayer they use for small spray jobs. Some use backpack sprayers for all of their herbicide applications. Often the most common use is to spray glyphsate (ie…Roundup) around the base of the vines. High pressure applications can result in smaller droplets that tend to drift more. The key to an effective glyphosate application is to spray the weeds and not the vine. This is much easier done when the backpack sprayer is set at a low application pressure. I find that a pressure of around 15 psi works best for me to control the application and reduce unwanted drift. Pressures above 20 psi can start to create fine particles that tend to drift more.
Using a pressure control valve or pressure regulator gauge placed between the pressurized tank and spray nozzle will allow the spray pressure to remain constant at a pre-set level despite the changing pressure in the tank. The pressure control valve also allows you to maintain a constant application rate. You will also find yourself not pumping up the pressure as often when you have a pressure control valve or gauge.

Some backpack sprayers like this Solo made unit above can be purchased with an adjustable pressure control gauge. Pressure Control Valves help to reduce spray drift and control the application rate.

Call for Entries - 4th Annual International Cold Climate Wine Competition

Deadline to register is August 6, 4:30 CDT
MINNEAPOLIS / ST. PAUL (5/25/2012) -Wines made from grapes grown in cold climates will be in the limelight when judges gather for the 4rd annual International Cold Climate Wine Competition this August.
The competition will take place Aug. 16 on the campus of the University of Minnesota, where several of the cold-hardy wine grapes were developed.
This year's competition includes additional categories for ice wines, cold-hardy fruit/grape blends, and wines made from the variety Brianna. Judges will do a blind tasting of the wines and award gold, silver and bronze medals, and best of show awards to the top red, white, and specialty wines. The "Governor's Cup" is given to the favorite Minnesota wine of the internationally recognized wine experts on the judging panel.
"Cold hardy wine grapes represent a specialty crop market with significant economic potential for the Midwest," said Ron Barnes, president of the Minnesota Grape Growers Association, the competition's primary sponsor. "Our competition highlights these new varieties and helps build consumer awareness and demand for wines made from these grapes."
Minnesota's grape and wine industry is expanding rapidly and last year contributed an estimated $40 million to the state's economy. Since 1995, the number of wineries has grown from seven to 43; total sales are expected to exceed $11.3 million by 2014.
"The competition is more evidence of the increasing quality of cold-climate grapes," said Jim Luby, a professor in the U of M's department of horticultural science and one of the scientists developing the grapes. "A number of grape varieties with improved potential for high quality wines have become available in the last 15 years. This competition is an opportunity for winemakers to showcase their skill and imagination in transforming these varieties to superior wines in a rapidly growing new industry."

Marketing Tidbits

“For U.S. craft brewers in the current economy, the beer glass is neither half full nor half empty: it’s filling up fast. Although craft beer still comprises less than 5% of the U.S. beer market, the segment has enjoyed double-digit growth for several years and is up 14% this year, according to the Brewers Association. Aiming to keep pace with demand, major craft players are expanding aggressively.”
