Minutes from Meeting at the Spring Auction

At the Spring auction there were several motions put forth and voted on by members present.

The first motion was made by Olga Crocker and seconded by Ernie Grimo, that we provide up to $5,000 of a $30,000 project to develop a heartnut cracker. The remaining $25,000 to be funded by a grant. The motion was passed. (The first application was turned down but is being resubmitted with the required alterations to be more in line with their requirements).

The next motion was made by Ernie Grimo, and seconded by Linda Grimo, was for SONG to purchase liability insurance to protect SONG executive and members. Motion passed.

Ernie Grimo mentioned that the Ontario Nut Growers Handbook is getting short in supply and Ernie is rewriting the handbook and is donating his time to do the rewrite. The project will be finished next year as it is quite an involved project with Ernie's busy schedule. We will apply for a grant to print the new book so there will be minimal cost to SONG.

Mogens Lief Anderson
A tribute to a man who loved trees

Moe Anderson was born 1928 in Fakse Ladeplads, Denmark. After completing high school, he studied at the Asmild Kloster forestry school where, after an interruption for compulsory military service, he graduated in 1953, then came to Canada. Rejoined the Canadian Forestry Service in 1962, and in 1968 was assigned to the Central Research Forest in Ottawa.

There he began the work for which he is so respected by ECSONG members, studying seed tree populations within a 100 mile radius of Ottawa with respect to site specificity, seed maturation, stratification and germination methods. The site covers 385 ha with plantations of 52 species, most native to the area and selected by Moe.

In 1979, Forestry Canada decided that our forestry future lay in our north, and closed the CRF project. Almost the only surviving records of the work done are those Moe preserved: his hand drawn maps, personal notebooks and photographs, and above all else, detailed professional memories. He gave his maps to the NCC, who entered them in their GIS, where they remain and formed the source of the maps on the ECSONG CRF website. The unplanted seedlings grown under his direction were mostly given to ECSONG for planting in the Baxter Conservation Area.

Moe moved to the Petawawa National Forestry Institute and continued his work with trees until his retirement in 1991, but remained a member of ECSONG. His first retirement project was to interest Mark Schaefer, RPF and ECSONG vice-president in the value of the abandoned CRF plantations - this led to ECSONG formally adopting them. I became their coordinator in 1999 and began scientific studies on the lessons that could be learned from Moe's work there. However, the first thing I did was to persuade the National Capital Commission to name one of the most successful plantations, the red oaks at the edge of Anderson Road, in honour of Moe. This was formally done on 20 May 2000.

Moe continued visiting to offer advice and help until the devastating progress of Parkinson's Disease constrained his love of trees to his back yard in Pembroke. Although he has now left us, his advice as a forester and his warmth as a friend will remain in the hearts of all who knew him.

The Walnut Lace Bug
A potential pest of walnut, heartnut and butternut
David Wees, Dept. of Plant Science, Macdonald Campus of McGill University, 21111 Lakeshore Road, Ste-Anne-de-Bellevue QC H9X 3V9

A few summers ago, I noticed a small bug on the leaves of the heartnut and buartnut trees in my garden of my former residence, located in Pointe-des-Cascades, Quebec about 40 km west of Montreal. I have also noticed what seemed to be the same insect on several butternut trees on the Macdonald Campus of McGill University in Ste-Anne-de-Bellevue about 25 km west of Montreal. In the summers of 1999 and 2000, the insects seemed quite numerous and I was concerned about potential damage to the trees. Sprays of insecticidal soap seemed to have little effect on the bugs. In the past two years, I haven't seen much evidence of the bugs on some young heartnut trees planted at the Horticultural Research Centre on Macdonald Campus.

After a bit of searching, I have tentatively identified the insect as the walnut lace bug (Corythucha juglandis). Lace bugs are members of the Tingidae family which belongs to the order Hemiptera or "true bugs". The nymphs (immature bugs) are black and quite small: they measure 0.5 to 2 mm long. The adults, 3.5 mm long by 2 mm wide, have an unusual appearance: their translucent wings have convoluted edges that have a "lacy" effect, hence the common name lace bug.

The adults overwinter on the trees and lay eggs in early June. The nymphs feed by sucking sap from the underside of leaves which, in a severe infestation, first turn white from lack of chlorophyll, then brown or bronze in mid-summer and then drop prematurely, often in August (Rose and Lindquist, 1997). The underside of the leaves may be covered with tiny black dots of excrement. Both adults and nymphs crawl slowly although the adults will fly short distances if disturbed.

Interestingly, most authors of books or bulletins on nut growing never mention the walnut lace bug as a pest. An exception is Duke (1989) who states that it can be a serious pest on the Eastern black walnut (Juglans nigra) but makes no mention of other Juglans species such as heartnut, butternut, buartnut or Persian walnut. In fact, it seems that it is mainly entomologists who have pointed out its importance. Osborn and Drake (1916) mention Corythucha juglandis as a "common species found on walnut and sometimes basswood". Drake and Ruhoff (1965) list butternut, black walnut and heartnut as well as service berry, hickory and basswood as hosts of this lace bug; they state that insect is distributed from New Brunswick south to Georgia, from New England west to Iowa and southwest to Texas. According to Rose and Lindquist (1997), the walnut lace bug is found wherever walnuts and butternuts grow in Canada and the United States; however Maw et al(2000) state that it is found only in Quebec and British Columbia. According to Stephanie Boucher, Curator of the Lyman Entomological Museum at McGill University, specimens have been collected in several locations in south western Quebec. I have found lace bugs (although perhaps a different species) on the leaves of hazelnuts and raspberries.

Several questions arise. Is the walnut lace bug a serious pest of nut trees in Canada? Do large populations occur only sporadically or in particular locations? Is this a new pest that we will have to deal with in the future? I would be interested in hearing from SONG members if they have encountered this insect. If so, on which species: black walnut, heartnut, butternut or buartnut? Did you see severe damage such as leaf browning and defoliation? Maybe you even have some insight as how to manage this insect in a nut grove.

Red Hot Nut Grower's Chili

A hearty vegetable-enhanced chili with robust smoky flavor, zesty spice, and definitive nutty character, this chili was created to celebrate the centennial meeting of the Northern Nut Grower's Association to be held at the Purdue University in Indiana in July 2009. It's surprisingly easy to assemble, yet delivers great flavor, bold seasonings, and plenty of nutritional vigor to satisfy a pack of hungry nut growers. Yield: 6 to 8 servings :

1/3 cup whole almonds, coarsely chopped
1/3 cup raw hazelnuts, coarsely chopped
1/3 cup raw walnuts, coarsely chopped
1/3 cup raw pecans, coarsely chopped
2 medium onions, chopped
2 green bell peppers, chopped
2 red bell peppers, chopped
1 large zucchini, chopped
1/2 cup water
6 cloves garlic, minced

1 28-ounce can diced tomatoes
1 15-ounce can pinto beans, with the liquid
1 15-ounce can kidney beans, with the liquid
1 15-ounce corn, drained
1 6-ounce can tomato paste
1/2 to 3/4 cup water
1 or 2 jalapeno peppers, finely minced
1 tablespoon red wine vinegar
1 tablespoon balsamic vinegar
1 tablespoon soy sauce
1 tablespoon plus 2 teaspoons chili powder
1 tablespoon plus 2 teaspoons ground cumin
2-1/2 teaspoons Wright's Natural Hickory Seasoning (liquid smoke)
1-1/2 teaspoons salt

Toppings
1 medium onion, chopped
1 6-ounce can black olives, drained and chopped
Preheat the oven to 350°F and have ready a 6-quart crockpot. Combine the nuts on a large jellyroll pan and roast them for 8 to 10 minutes. Immediately remove them to a plate to cool and set aside. Combine the onions, green and red bell peppers, zucchini, water, and garlic in a large, deep skillet and cook and stir over high heat for 5 to 7 minutes, or until the vegetables are softened. Add more water if needed to prevent burning the vegetables. Transfer the cooked vegetables to the crockpot and add the roasted nuts and remaining ingredients, except the toppings. Stir well to distribute the ingredients evenly. Cook on low setting for 6 to 8 hours and serve in bowls with toppings on the side.
