How to kill dandelions in the yard or vineyard without harming the grapes is one of the most common questions I get this time of year. It is amazing how a few dandelions popping up in the grass can remind us of a question that should have been asked last fall.
(R) Early season dandelions are an excellent food and pollen source for honey bees early in the season.
Here is the real scoop about broadleaf weed control in turf or pasture. The best and most effective time to control broadleaf weeds in turf or pasture is during the first 3 weeks after the first killing frost in the fall. This first killing frost normally occurs during mid-October in Iowa. The frost will kill the leaves of sensitive nearby plants while the leaves of winter annual, biennial and perennial weeds close to the ground remain untouched, still sending nutrients into their roots to help survive the winter. The typical 2,4-D alone or 2,4-D/dicamba/MCPA phenoxy mixed turf sprays are very effective this time of year. The second best time to spray broadleaf weeds in turf or pasture would be in early spring before phenoxy susceptible plants leaf out, (e.g. before grape bud break). The worst and least effective time to kill broadleaf weeds in turf and pasture is now and through the hot summer months.
Nutrient flow is moving upwards and higher temperatures aid in the potential volatilization of these phenoxy herbicides.
Yes, there are some phenoxy herbicides that are less volatile than others and you may be able to get away with an application this time of year under cool temperatures, but the risk of herbicide damage is still there. I am willing to discuss these options over the phone, but certainly will not guarantee the results. Spot spraying with Roundup (glyphosate) or digging them out may be your best options this time of year.
The real question should be, what is wrong with a few dandelions?
Some of you readers can still remember when dandelion covered yards were the norm instead of the bane of a neighborhood. I feel sorry for the kids growing up today
not knowing how to make dandelion necklaces out of the hollow stems, blowing the dandelion fuzz into the air or holding the flowers under ones chin to determine whether
or not they liked butter by the presence or absence of the yellow reflection. Those were simpler days. We now demand Astroturf-like yards with small signs warning people to stay off due to pesticide applications. I prefer the simpler days!
Dandelions (Taraxacum officinale) evolved over 3 million years ago in Eurasia. They are very unique plants, being able to cross pollinate or produce seed via self fertilization. They have a single tap root that will often be 10+ inches long and can live for two years (biennials) or several years (perennials). Dandelion comes from the old French phrase "dent de lion" meaning the lion’s tooth describing the coarsely toothed leaves. The modern French word for dandelion is "pissenlit", meaning urinate in bed because of its diuretic affects. Pissabed is the old English folk name for it.
There are many things dandelions can be used for:
a. Used as a medicinal herb: http://www.umm.edu/altmed/articles/dandelion-000236.htm
b. Leaves, buds, flowers and roots can all be eaten as vegetables high in vitamins A, vitamin C, calcium and iron. http://www.squidoo.com/dandelion-recipes
c. Dandelion Wine: http://winemaking.jackkeller.net/dandelio.asp
d. Dandelion Beer: http://recipes.egullet.org/recipes/r1934.html
e. Dandelion flower jam: http://www.recipecottage.com/preserving/dandelion-jam.html
f. Dandelion root coffee: http://www.prodigalgardens.info/dandelion%20coffee.htm
g. Milky latex has been used a mosquito repellent and wart remover.
h. Yellow and green dye can be obtained from the flower parts.
i. Important nectar and pollen for bees.
j. Dandelion syrup: http://fxcuisine.com/default.asp?Display=78&resolution=high
k. Dandelion flower fritters: http://www.learningherbs.com/dandelion_recipes.html
It would be remiss of me to not mention a few minor negatives of having a healthy stand of dandelions in your vineyard. Dandelions can compete with the grapes for water and nutrients. Dandelions along with a few other broadleaf weeds can also be a host of dagger nematodes that can transmit several virus diseases to grapes. And finally, dandelions, can attract gophers into a vineyard.
Lee Lutes (Black Star Farms) and Dave Miller (White Pine Winery) have started an initiative to aggregate industry funds to support research and Extension activities to meet the future needs of the Michigan wine industry. Click here to read the letter.
Regional industry meetings will be held over the next few months to discuss this concept. Anyone affiliated with the Michigan wine industry from around the state is encouraged to attend (winery representatives, individuals representing supplier organizations, economic development partners, etc.). The first meeting will be held May 23 at 4 pm in Room A of the Oleson Center at Northwest Michigan College in Traverse City. Watch for other meetings to be announced on the industry calendar of events at michiganwines.com.
The Michigan Grape and Wine Industry Council encourages members of the industry to give this initiative their support as an important step in the Michigan wine industry's continual evolution. For more information, contact Lee - email@example.com , or Dave - firstname.lastname@example.org .

I was able to attend the vineyard field day held at Fox Run Farms in Brainard, NE this past Saturday. This event was co-sponsored by the UNL Viticulture Program and Yolanda & Larry Bailey of Fox Run Farms, Fox Run Farms produces garden crops and has a 1.5 acre vineyard that was established in 2007 consisting primarily of Brianna and Marquette grapes. Yolanda (Yola) is the primary manager of the operation. They also have a Consumer Supported Agriculture (CSA) business that is now entering its 4th year of operation.
Viewing the different vineyard floor management research plots that UNL graduate student Christina Bavougian established in 2010 & 2011 was the primary reason I wanted to attend this field day. It also worked well into my schedule of picking up some honey bee packages for my bee yard from a honey producer in Western, Iowa.
The following information comes from a handout provided by Christina at the field day:
Objectives of this research are to investigate alternatives to synthetic herbicides for weed management and to evaluate the potential for living mulches to reduce vegetative vigor in southeast Nebraska vineyards. Research plots were established in 2010-2011 at Fox Run Farms in Brainard, NE. The vineyard is Vertical Shoot Positioned (VSP) trained Marquette vines planted in 2007.
3 alleyway treatments:
- "Boreal" creeping red fescue (CRF)
- "Park" Kentucky bluegrass (KBG)
- Resident vegetation (control)
5 in-row treatments:
- crushed glass mulch (CGM)
- "Boreal" creeping red fescue (CRF)
- dried distillers grain (DDG)
- glyphosate (GLY)
- weedy control (WC)
Alleyway treatment results:
- Affected Brix and pH in 2011 (KBG > CRF > control)
- Affected pruning weight in both years (KBG) = CRF > control)
- Did NOT affect yield, shoot length, canopy density, soil & vine moisture status
In-row treatment results:
- CGM increased soil Temperature (T), vine and soil moisture, shoot length and leaf layer #
- CRF reduced soil T, vine and soil moisture, shoot length, leaf layer #, 2012 pH. Easy to establish; excellent weed control and complete soil coverage; may require mowing once per season.
- DDG increased soil T, vine and soil moisture, shoot length, leaf layer #, 2012 pH. Potential for effective weed control (application time is key); requires several applications per season.
- GLYhad intermediate soil T, soil moisture, shoot length, leaf layer #; reduced 2012 pH. Effective weed control with ~3 applications per season
- WC reduced soil T, vine and soil moisture, shoot length, leaf layer #, 2012 pH. No weed control, complete soil coverage; may require mowing once.
- None of the in-row treatments affected yield, pruning weight
- CGM, DDG, or other mulches could be good options for newly planted vineyards.The conserve water, protect soil from erosion and control weeds.
- Living mulches (like CRF and WC) can perform well in ESTABLISHED vineyards. They require little maintenance, protect and improve soil and can reduce vine vigor.

Ecosystem Services are goods and services humans obtain from managed and natural ecosystems such as food, fuel, fiber and recreation. Pollinators & Natural Enemies are examples of beneficial insects that play a vital role in ecological processes that support these services.
Providing a diverse plant habitat is key in attracting and maintaining these beneficial insects.
Conserving Beneficial Insects with Native Plants is a new 2 page publication from the ISU Leopold Center that provides guidance on selecting and establishing native plants.
Almost every vineyard and/or winery has an area that can be turned into a native planting. This new FREE publication can help you get this done. Check it out here:

Iowa State University (ISU) Extension and Outreach worked with iOS app developer Rade | Eccles to develop the Pesticide and Field Records iPad app to help producers and agriculture businesses record and maintain pesticide application information. The free iPad app allows users to link information to specific field locations using satellite mapping and document pesticide application information needed to comply with state and federal record-keeping requirements. The app also features a product search option that lists Environmental Protection Agency (EPA) product registration numbers and identifies restricted use products.
Development of the app was funded by the ISU Extension Pest Management and the Environment program and a grant from the EPA under assistance of the Iowa Department of Agriculture and Land Stewardship Pesticide Bureau.
