Grapevine Control Indiana DNR
Hi i'm sam carman with the indiana division of forestry.If you come into most indiana woods you'll find vines.I'm here with district forester janet eger, janet are these vines a problem to the trees it depends on what types of vines we're talking about, sam.Grapevines are definitely a problem for trees.If you're trying to grow timber grapevines can cause a lot of harm to the growth and development of those trees.Other types of vines, such as poison ivy and virginia creeper, provide no harm to the tree and actually have wildlife benefits.Now grapevines can.
Also have wildlife benefits and we don't always want to eliminate all the vines in the woods.But we do want to be particular about the areas we eliminate them.So where might you leave a grapevine the best places to leave grapevines are around edges of the woods because that is the most productive area for wildlife anyway.Or down in the center of the woods if you have a cull tree, a tree that's no good, and the vines are not spreading out into some of your desired crop trees.That would be a good place to leave vines also.
So you mentioned that grapevines can be harmful to the trees, how can you tell them apart from the other vines it's fairly easy sam, with grapevines, they will always swing free from the trees.Desirable vines such as poison ivy and virginia creeper will have little feet that attach themselves directly to the tree.You see how shredded and raveled that grape vine is, a lot of squirrels and birds will use those ravelings to help with their nest building.That's why we don't want to eliminate all of the grapevines in the woods, but again we want to make sure.
We eliminate the vines out of our desired crop trees.Okay, and how do we do that there's two ways.You can either use a chainsaw or you can use clippers, it depends on the size of the vine.We're going to work on this vine first.He's going to cut up high and the reason to do that is because if you are working in the woods and there is a lot of grapevine around, they can sometimes appear to grow before your eyes, and if you cut high you can see immediately that you've cut that vine.So he's going to cut up high, that's.
The visual one for him.And then he's going to make a cut down low and you want to make this low cut within 12 inches of where it comes out of the ground.That minimizes and potential sprouting.All right sam, we've got the two vines cut, but we want to ensure that they stay dead, so we're going to treat these cut stumps with a chemical that is designed specifically to kill the vine.So that chemical will actually go into the roots of the vine and deaden it.
Serving Growing Ohios Grape and Wine Industry
Last january, january 6th the official day of the polar vortex we experienced really damaging temperatures.Anywhere from around twenty below zero to about sixteen below zero where it killed the fruiting buds and it killed actual grape vines.And we've never experienced any damage like this before.And we've never we really didn't know the extent of the damage on the vines until april may in that time frame when we didn't see any buds developing and even some of the trunks cracked.But the impact of that was dramatic we have no crop at all in our vinifera.
And we grow varieties like chardonnay, pinot noir, cabernet franc, riesling and without any grapes, we were forced to buy a lot of grapes.But it's had a huge impact as far as the grape production not to mention the actual wine loss which is two or three years spanning.Because in some of the vineyards that will have to be replaced from the ground up with new vines we will not get the first crop is three to four years out.So the impact is just dramatic and millions and millions of dollars.Actually in the viticulture program at.
Ohio state one of our focus of the research is cold hardiness of grapes.So really that's one of my expertise in this field of learning more about how grapes cope with freezing with cold in general.After this cold event our growers really needed a lot of help in terms of how to not only assess the damage but also how to deal with the vines that are damaged.And we conducted a lot of workshops just to show them how to prune the vines.Our relationship with ohio state goes way back.
In the 1980's we've had a long standing relationship with ongoing research in the winery and in the vineyards.Currently with imed dami our research stems lately from the cold winter vortex where we've had a lot of the vines killed and damaged from the minus twenty degree temperatures.Current research is kind of involved to the extent of the damage to determine the actual damage and to have pruning studies done to see what was the best way to prune these injured vines.We have not had temperatures that cold since 1994 here and.
Over Wintering Strategies New vineyard management practices
Light, electronic music fades in.Narrator canadian winters can be tough on wine grape vines.A single extreme cold snapcan damage vines and reduce crop yields by 20 to 30.When temperatures drop below 20 for an extended period, the whole crop is at risk.And it takes two years for a vine to recover, amounting to a significant financial loss for growers and vintners.Carl bogdanoff and his team at the pacific agrifood research centre, in summerland, british columbia..Are working with grape growers to better protect vines against the deep freeze.
Carl bogdanoff in the past, say about 30 years ago, the wine industry was fairly small..And also was based on winter hardy hybrid varieties..Which produced fairly medium quality wines.The wine industry here in british columbia decided to focus primarily on..Quality and to do that they replanted all their vineyards with premium vitus vinifera varieties..Such as merlot, cab franc, chardonnay.All those wine varieties that we know and love.Vitus vinifera can tolerate some freezing but they are seriously tested when temperatures become record low temperatures.And when we do get these really freezing temperatures, grape buds are killed.
.Vine tissue is damaged, the flowum or zylum or even the roots are damaged, or the vine could be totally killed outright.Narrator it is a multidisciplined initiative that is fully engaged with the industry.The team monitors temperatures and bud hardiness at many locations across the okanagan and similkameen valleys.Participating growers receive a biweekly, bud hardiness report for major wine grape varieties.They use this information to assess risk of winter injury before and during an arctic event..To help them decide when to operate fans that draw warmer air into vineyards.
Knowing bud damage levels also helps in deciding how much to prune.Carl bogdanoff last winter, this vine was compromised.It's flowum and zylum cells were damaged.It wasn't completely girdled, so this vine broke bud..Sent up some shoots and had some crops but when it got really hot this summer..This vine totally collapsed and now is dead.Narrator additionally, the research team collects data in several other current research projects..That are looking at the effects on hardiness of rootstocks and varietal selections..Irrigation practices, use of fans to mix air in the vineyards.
.Amount of crop on the vines, ground cover between vine rows, disease..Leaf removal and cluster positioning..And how a plant hormone, one that improves grape colour, is also contributing to bud hardiness.Mike watson anything we can do to make the vines hardier, even by 2 or 3 degrees..Is huge.It's the difference between up to 50 damage..And replanting crop loss to having a total successful year in the succeeding year.Carl bogdanoff it is really important that we understand..How we can help these vines weather these cold snaps that occur periodically.
