Prairie Yard Garden Growing Grapes

(gentle music) Prairie Yard Garden is a production of the University of Minnesota Morris in cooperation with Pioneer Public Television. Closed captioning is provided by Mark and Margaret YackelJuleen in honor of Shalom Hill Farm, a nonprofit rural education retreat center in a beautiful

prairie setting near Windom in southwestern Minnesota. Shalom Hill Farm, shalomhill Did you hear that a new crop is appearing on the prairieé Growing grapes has created an interest among a few individuals who like the challenge of adapting it to our region. Join me on Prairie Yard Garden as we visit a vineyard to learn about the process and challenges

of growing grapes on the prairie. (soft lighthearted music) A new crop has appeared on the prairie: growing grapes And today I have Florian Ledermann with me who's been involved with the process for the last four to five years. Florian welcome to the show and tell me, how did you get interested in growing grapesé ^We got interested actually at the

University of Morris's Horticultural Night. We sat down in a tent and learned that the university just released four new varieties of grapes that are actually coldhardy. And before that, I always kind of figured grapes were the crop that just kind of came up and never really bore and died every winter and died back. So that's what spiked our interest.

And so that very nextspring, we bought five. And they survived and I did a little more research and decided to go with an acre. And a year later, another acre so we ended up with 1,350 vines as a result of that little adventure in Morris. Larry That's interesting. 1,300 vines, how long does it take you

to put all those in the groundé Florian We used family labor. (Florian laughs) So we had, it took us, I think probably when we were planting, it took us about threedays to put one acre in. That would be for the planting. The posts and the trellis system and everything

Intro music gt;gt;Hoffman: Part of my job as either the lead biologist or the new product development manager was to send out the global field protocols and people would say, quot;Lisa this protocol the compound's never gonna work that way. You're crazy. You need to increase the rates, or you need to reduce the spray intervals.quot; And I said, quot;No, no, really, trust me it's gonna work that way.quot; gt;gt;Pasteris: The fact that it had excellent preventative activity

and excellent curative activity at low rates was a key indication that we had something really special here. gt;gt;Neves: I'm unaware of any other product in the market nowadays that provides this level of prevention and disease control. gt;gt;Pes: After I saw it, and the great level of protection that it guaranteed on the vineyards, I was surprised. I was not expecting to see such performance. gt;gt;Rhouwen: I've seen six demonstration tests of Zorvec on cucumbers so far.

I would describe my feeling on site with the word 'shocked' or the phrase 'very shocked', even 'extremely shocked'. gt;gt;Hoffman: I would tell the grower that they can stop worrying because Zorvec is really going to do all the things that they need it to do. gt;gt;Neves: What I have to say about Zorvec is: quot;You have never seen anything like it.quot; You need to see it to believe it.

DuPont Zorvec Disease Control This Changes Everything

Intro music gt;gt; Haiyan: In the demonstration test, we could see the great effect of Zorvecâ„¢. I find it really amazing. I've never seen such an effective product before. gt;gt; Pes: In this area, northeastern Italy, the most important fungal disease is the peronospora. If not treated on time, the peronospora can cause great damage to the vineyard, including loss of production and quality of wine.

gt;gt; Oliveira: The potato blight is the potato's main disease. If it's not managed and controlled, it can decimate a crop. so it can destroy 100% of the crop. gt;gt; Chunxiang: Downy mildew is the most serious disease for cucumbers. In the most serious cases, the leaves will be dense with yellow spots, the whole blade will get dry and the leaves in the middle and at the bottom will all get yellow. This will directly affect the yield.

gt;gt; Hoffman: Well, in the early days of discovery and development it was very difficult to keep people from talking about Zorvecâ„¢ because it was just so amazing. They didn't know exactly what it was but they knew DuPont was testing a new oomycete product and they all wanted to talk about it. They all wanted to know what it was. gt;gt; Pasteris: Most commercial products that are out in the marketplace now have one, two or three of the key attributes a grower is looking for but none of them have them all. But when you look at Zorvecâ„¢, it basically has every single attributethat a grower is going to want

so it makes it easier for the grower to manage his crops. gt;gt; Haiyan: Zorvecâ„¢ was used on one side of my greenhouse, not the other. After Zorvecâ„¢ was sprayed, the leaves grew greener and thicker, vines got stronger, clusters spread fast and pedicels grew longer, fruits were longer and brighter in color. We couldn't even hold them in our arms. gt;gt; Pes: This comes from areas that have not been treated against peronospora. On the other hand, this cluster of grapes

comes from the area treated with Zorvecâ„¢. The difference is enormous. gt;gt; Neves: When Zorvecâ„¢ is approved in Brazil, I believe it will tip the potato blight control market in Brazil, it will be amazing to the people, the growers, because it will bring a new concept of control that people don't have and it will give the growers flexibility they've never experienced. gt;gt; Sweigard: I've had a lot of neat discoveries in my life

The Zorvecâ„¢ discovery figuring out the target site of Zorvecâ„¢ is the single most exciting thing that I've done in all the different areas of research that I've worked.
