Species Identification

Is there a facility at OSU that is able to identify topical species of wood products? My company is an importer and distributor of forest products that are sourced from the Amazon basin. Often times multiple species are lumped together for commercial purposes when being shipped from Brazil and there are certain times when it is important to narrow down the genus and species of the lumber we are sourcing.

Potatoe Disease

Hello, Last year I planted 6 potatoes. All different varieties. 5 of them produced normal fruit. One of them got a disease. The top of the plant looked healthy. However the tubers had brown spots. There were many tubers, so it did not affect production. However every single potato had brown spots. I am attaching the pictures. Could you please let me know: 1. If you can tell what this disease is? 2. Is this contagious? I am not planning to plant new potatoes in exactly the same spot, but it would be into the same garden bed (the opposite end of the bed that I used for potatoes last year). If I remember correctly, this specific potato variety was German Butter Ball. If specific varieties of potatoes are more susceptible to this disease, would you please let me know? Thank you, Val Fearnside

Snow Pollution for Science Experiment

Hello! My name is Holly Willson. For a school science experiment, my son wants to test the pollution in Michigan snow. In one day, he collected snow from Detroit, West Branch, Mackinac City, and Sault Sainte Maire. He would now like to send the melted snow to a lab to be tested, or he would like to know what type of kit he could buy that would give him the best results for testing pollution. Many people have referred us to M.S.U. Is there anyone who would be able to help us? Thank you! Holly Willson

Native Understory Shrubs

Our property is full of shrub Japanese honeysuckle as an understory plant. The birds, doves and cardinals in particular (large enough to see), use it as perch near feeders. Is there a native that could be planted to fill that niche? My neighbor has honeybees, and I'm concerned about using Mountain Laurel or a relative that might affect honey production. I've heard that MT nectar is not good for honey. Thanks.

cutting off the tops

Will it seriously damage my arborvitaes if I cut off the top 4 feet? Will it grow back ? I have 2 arborvitae that have been growing in large brick planters for about 15 years. They grow to about 11' high and are too tall for the area. Although I trim 6" - 12" off the tops every 3 - 4 years, they always grow back. I am considering taking off about 4' in late November so I won't have to trim them so often. Will it seriously damage them or kill them? Will that much ever grow back?
