IWGA Bus Trip to Michigan Viticulture Field Day

The Iowa Wine Growers Association is hosting a bus trip to attend the 22nd Annual MSU Viticulture Field Day held on Wednesday, 7-27-11 at the Southwest Michigan Research & Extension Center near Benton Harbor, MI. This is one of the largest vineyard field day events held in the Midwest. They typically get over 200+ people in attendance . The vineyard demonstrations and large vineyard equipment trade show is well worth seeing. This event always ends with a fun and tasty steak fry with plenty of Michigan wine put on by the Michigan Grape Society.

(Above) WindStar Lines of Carroll, Iowa will be providing the transportation on this trip.

The trip starts out on Tuesday morning, 7-26 at Summerset Winery in Indianola and heads for Benton Harbor, MI. The tour will be stopping at Lavender Crest Winery in Colona, IL for lunch and Round Barn Winery, Distillery and Brewery in Baroda, MI in the afternoon before arriving at the Days Inn & Suites in Benton Harbor, MI that evening. The entire Wednesday will be spent attending the MSU Viticulture field day. The trip back on Thursday will include a stop to visit with Dan Nitz at Arrowhead Vineyards in Baroda, MI and then lunch at Anderson Winery in Valparaiso, IN. The bus will arrive back at Summerset Winery late Thursday evening, 7-28.

The cost of this tour will be $60 for IWGA members and $85 for non-members. This will cover the transportation and the field day registration which includes Thursday’s lunch and steak fry. Participants will be responsible for all other costs. The Days Inn & Suites at Benton Harbor has a block of double queen-bed rooms for $80 and single king-bed rooms for $70 plus tax. Participants need to make their room arrangements here by July 9th to get these reduced prices.

MAST Looking to place International interns into wineries

I received an e-mail from Sue Riesgraf, one of the International Coordinators working for MAST at the University of Minnesota. Sue mentioned that she has several potential internship candidates from Germany, France and Eastern Europe who would be interested in working in a winery. MAST interns typically have two or more years of education and/or experience in the field that they want to work in. Host families are expected to provide housing and fair wages equivalent to a 40 hour work week to these interns for a period of 4-12 months depending on circumstance.

MAST International is an international agricultural exchange program at the University of Minnesota providing practical and academic training in American agricultural and horticultural production. The program mission is to improve global understanding by providing educational and cultural enrichment through international exchange. MAST interns are placed all over the U.S.

Here is a chance to add a little International ambiance to your winery! mlw

Christmas Tree Knives for Hedging, Topping & Skirting

It is that time of year again. People are starting to contact me about where to buy those Christmas tree shearing knives that I have recommended in the past. These knives work very well in trimming back bushy vines. Unfortunately, “bushy vines” generally denotes too much vigor and a vine that is out of balance with its crop load and/or environment. Generally speaking, it

is better not to cut off excess vegetation unless it causes undue shading of the fruit, hampers other vineyard operations, or significantly reduces airflow
through the vineyard.

Hedging, topping or skirting are best done when plant vegetative growth is slowing down (ie…last 2 weeks prior to veraison) but not after veraison. Pruning the canopy back after veraison can have a negative effect on fruit ripening. Trimming back the shoots too early in the season will stimulate
lateral shoot growth negating the reason for trimming in the first place. It can become a vicious cycle in over vigorous vineyards.

Topping involves topping the canes at approx. 8-12” above the top wire on our vertical shoot positioned (VSP) trellis systems. Skirting involves trimming the canes approximately 12” above the ground on our downward positioned trellis systems and hedging involves trimming back those wild shoots that stick out the sides of the canopy and will not submit to positioning. It is commonly recommended to leave at least 12-15 nodes (leaves) on those shoots with grape clusters and aim toward a total canopy horizontal depth of 2 to 3 leaves. I put together a brief document summarizing these methods of canopy management here: Canopy Management Concepts

I like to use the Christmas tree serrated blade versus the straight steel blade because the serrated blades will stay razor sharp for several years. The straight steel blades need to be sharpened several times a day under heavy use. These knives normally come with combinations of 10 -18” handles and 12 to 24” blades. They normally cost anywhere from $45 to $65 each. I personally like a handle around 14-18” and a blade around 14-16”. The serrated blades are “VERY” sharp. I strongly recommend wearing long pants when using them. Leg protectors can also be purchased for around $30 to $45 each.

Show n Tell

(Left) This picture of Cottony Maple Scale on grape trunks comes from Joe Ayers in Eagle Bend, MN. Cottony Maple Scales (Pulvinaria inumerabilis) are soft shell scale insects that tend to infest maples, typically Silver Maples,
though they can be found on other hardwood trees and shrubs. This includes grapes. The immature female scales overwinter on the tree or vine. During June to early July, a cottony egg sac is produced by the female under its protective soft shell. Each sac can hold up to 1,000 eggs. The eggs hatch in July and move to the lower leaves where they suck sap along the leaf
mid-veins. They move back to the trunks or twigs in the fall.

Very seldom will the population of this insect reach economic levels in grapes. Weather and a whole host of natural predators typically keep their populations in check.

If control is necessary, an insecticide application when the newly hatched nymphs move to the leaves to suck sap will work well. An application of dormant oil in the fall to the overwintering female scales will also work. Weather and a whole host of insect predators will normally keep these insects in check. Control measures are very seldom required.

These scales definitely attract attention when they are found. Ants are often found tending the scales as they suck plant sap. Honeydew excreted by the scales is collected by the ant and taken back to their colony as feed. A black sooty mold will often form on the excess honeydew formed on the leaf or trunk.
