Timely Pest Control – Starts Now

The four primary pests that top the list to scout for and manage as buds begin to break and expand this time of year are” Grape Flea Beetle, Climbing Cutworms, Anthracnose and Phomopsis.
Grape Flea Beetle, aka Steele Beetle (Altica chalybea – Illiger)
Adult BeetleLarvaGrape Flea Beetles are approximately 3/16” long, overwinter as adults and are steely blue in color. They tend to jump when disturbed and feed on swelling buds until they have elongated to about ½” in length. Economic treatment thresholds typically call for treating when 2-4% of the buds are damaged. Larval damage that shows up a few weeks later on the leaves very seldom causes economic damage. Flea beetle populations are often localized and are near the edges of the vineyard. They also feed on Wild grapes and Virginia Creeper.
Adult Beetle (Above, Left) Larva (Above, Right)
Climbing CutwormClimbing Cutworms feed on emerging buds and chew on the newly expanding leaves. Cutworms are the larva of several types of Lepidoptera species of adult moths. Some cutworms originate from eggs laid in weeds and grasses by moths blown in by southerly spring winds. Others, overwinter in the larval stage in the soil and feed early in the spring. Larva can start to cause damage when they reach 3/8” to 1/2” inch in length and can feed for 2-3 weeks until they get about 1.5” to 2” in length, when they pupate in the soil and emerge as another generation of adult moths.

These unique caterpillars will climb up onto the vines at night and will return to the vineyard floor and hide during the day . Economic treatment thresholds are similar to Flea Beetles where 2-4% of the fruiting buds are being damaged. Later spring season leaf injury is generally not a concern.
AnthracnoseAnthracnose, (right) aka Birds Eye Rot (Elsinoe ampelina) is an early season fungus disease that is primarily controlled by dormant applications of liquid lime sulfur or Sulforix just prior to budbreak. Anthracnose overwinters as dormant sclerotia that when become wet will release spores and conidia for further infection of the newly forming shoots and leaves. Temperatures in the range of 36-90°F and 12-24 hr. periods of wet weather are key to the spread of this disease. Foliar fungicide sprays for this disease should begin at ½” shoot lengths and continue as needed every 5-10 days depending on label recommendations. The potential of further infection declines during the summer months.
Phomopsis Cane & Leaf Spot, aka Dead Arm (Phomopsis viticola) is an early season fungus disease favored by wet weather and optimum temperatures in the 50-68°F range. Leaf Phomoposis Cane Symptomssymptoms show up as small brown-black dots surrounded by yellow halos. Shoot infections show up as elongated lesions or cracks. Rachis infections typically occur early when the cluster first appears up through 3” shoot growth. Rachis infections can result in late season fruit drop. The fruit is infected around the bloom stage. Infected berries turn soft and brown around harvest and  will have many small black raised pimples on the berry skin. Protectant fungicides applircations should begin at 1” shoot growth up until fruit set.

Christina Bavougian, PhD candidate will discuss her unique experiments employing crushed glass and distillers dried grains as mulches, in addition to her in-row and alleyway cover crop studies – Christina has some really interesting results! University of Nebraska Viticulture Program experts, Professor of Viticulture Paul Read and Viticulture Technician Steve Gamet will discuss canopy management, vine balance, late pruning and crop estimation and answer your other vineyard management questions, including disease and insect prevention and management.

Ever wondered what that weed was? Have you wanted to know how to control it and other weeds in the most effective and efficient manner? Answers to these and other weed management questions will be provided by UNL’s weed specialist, Lowell Sandell. Lowell will also conduct a weed survey in and adjacent to the vineyard, identify any mystery weeds that you may bring and provide insights and examples related to weed management strategies for your vineyard.
Steve and Diane Makovicka have invited attendees to visit their nearby winery, one of Nebraska’s newest, to see their specially designed tasting room and sample some of their wines
Of special note is the generosity of Fox Run Vineyards, both for providing a location for Christina’s PhD research studies and allowing us to hold this Field Day. We also appreciate the chance to observe their Community Supported Agriculture (CSA) enterprise. We appreciate their hospitality.

The bad news is that the Midwest Snow Storm of May 2nd & 3rd surprised all of us. North and west parts of Iowa were hit pretty hard. Reports of 12 – 14” of snow in northern Iowa, roads closed, cars in the ditch, and snow plows pulled out of storage and placed back on the trucks were common. The good news is that “Most” of our grape buds had not opened up and temperatures remained just barely above freezing. Below are some local pictures I took on 5-3-13 in the Indianola, Iowa area:

On Saturday (5-4-13) I drove over to Soaring Wings Vineyard at Springfield, Nebraska with Dave Klodd of Annelise Vineyard of Indianola, Iowa. Dave was picking up some used winery equipment he had purchased from another winery in Western Nebraska. Jim Shaw, owner of Soaring Wings Vineyard offered to transfer the equipment into the U-Haul we were driving with his forklift. Jim Shaw gave us a complete tour of his winery, brewery and vineyard while we were there. It was quite the tour. The beer and wine were very good and Jim was a very cordial host. I have posted 43 pictures of this tour into a photo album on my facebook page here: https://www.facebook.com/profile.php?id=100000304374293&ref=tn_tnmn
Here are some samples of some of things we were able to see: :

Dave Klodd and I also stopped by Prairie Hawk Vineyards located in Councial Bluffs, Iowa on our way back to Indianola. We were lucky to find the owner’s, Lee & Dawn Rice and their daughter In the tasting room where we tasted some wine and talked about the industry. I have placed five pictures from this visit into an album on my facebook page here:
