Do you have a Roundup Ready soybean field with suspicious broadleaf weed escapes?

The University of Minnesota Extension and North Dakota State University are collaborating on a survey of Roundup Ready (RR) soybean fields to evaluate possible resistance to glyphosate in broadleaved weeds that have survived herbicide treatment.

We are asking for your assistance to identify RR soybean fields with broadleaf weed escapes that can't otherwise be explained by skips, wheel tracks, or other reasonable possibilities. There is some indication that ragweed has escaped maximum labeled rates of roundup in Valley fields.

If you have a field that you would be willing to have sampled, call one of the project members at the end of this article. The process is simple: We will ask for a brief field history and one of the project members will collect a sample of the seed (plants). Results of the survey will be available to you upon request. There is no charge for having fields sampled.

Strawberry root weevils

Strawberry root weevils are a very common insect found throughout Minnesota, and are again 'bugging' some people and invading their homes in this area of the state. The shiny black, hard-shelled adult weevils about one-eight inch in length, develop from larvae that live in the soil and feed on the roots of strawberry plants, evergreen trees and shrubs.

In mid-summer, the adults emerge from the soil. They feed on plant foliage but cause no significant damage to the plants. They would go unnoticed except that large numbers regularly wander into houses by mistake as "accidental invaders." These are not damaging to the house or furnishings. They do not harm people or pets, and are a nuisance only by their presence.

Combating strawberry root weevils in the house can be difficult and frustrating. Some of the invasion can be prevented by exclusion techniques that close their routes of entry. Look for and seal cracks and gaps in the foundation and around windows and doors -- through which the adults can crawl into the building.

Spraying a residual insecticide on and along the foundation and in outdoor areas of weevil abundance may reduce the number of weevils outside and thereby reduce the number wandering in.

Adults already inside need only be vacuumed or swept up and discarded. Household aerosol insecticides are not very effective for controlling these weevils.
