Applying Biological Control Methods For Weed Management – MSU Weed Post

Sunday, December 30th, 2012


Biological control agents are organisms (e.g. insects, nematodes or fungi) that can be used to manage large weed populations. Typically these organisms are natural enemies of the target species in their native continent and are introduced to their new range following testing to ensure they do not harm non-target plants. Biocontrol agents have been approved and released for several weed species in Montana. Download the complete post to find out the ins and outs of biocontrol from beginning to end.

Weeds and Wildfire – October 2012 MSU Weed Post

Monday, October 1st, 2012


The October Weed Post, featuring weed management after fire is available from MSU.  The hot, dry, and fiery summer experienced in much of Montana and many other states in the Rocky Mountain region has prompted a great deal of interest in weed management following wildfire. Weed response to fire is dependent on many factors including propagule pressure (reproductive structures like seeds and root fragments, both above- and belowground), time since invasion, competition with desired vegetation, disturbance history, rainfall patterns, soil characteristics, plus the actual dynamics of the fire itself (e.g. temperature, duration, season), and the type of plant community where the fire burned, for example mountain grasslands versus lodgepole or ponderosa pine forest. Weed response to fire also depends on the regeneration strategy of the weed species of concern. Research suggests that most post-fire plant cover originates from resprouting. So, weeds that resprout from vegetative structures may respond quickly following fire as compared to weeds that have to regenerate from seeds.

2012 North American Invasive Plant Ecology and Management Short Course

Friday, May 18th, 2012


In just over a month the 2012 NAIPSC will take place in North Platte, NE. Organizers have extended the registration deadline for the 3-day course to June 18, 2012. If you are thinking about attending the NAIPSC and have not been able to decide, here are some things to consider:

The 14 instructors teaching at the NAIPSC represent 8 states, including North Carolina, Kansas, Wyoming, Montana, Oregon, Idaho, South Carolina, Nebraska, and Oklahoma.

  • There will be 3 separate workshops on topics related to plant identification, invasive plant physiology, and technology for locating and mapping plants.
  • The materials provided to participants include 3 books, a CD for identifying plants in North America, and the 2012 NAIPSC binder.
  • All participants will enjoy catered lunches and breaks each day, and a BBQ dinner/tour of the historic Buffalo Bill Ranch house and barn.

This is just a sampling of the offerings at the 2012 NAIPSC. Each day will be filled with activities and information that will help participants answer questions, address challenges, or gain new understanding related to invasive plants.

Noxious Weed Managment Certification Program

Saturday, April 21st, 2012


The Noxious Weed Management Certification program is a series of workshops about weed biology, ecology, and management. It is designed to benefit those new to weed management and experienced professionals. Participants have included, but are not limited to, county, state, and federal agency personnel, non-governmental organizations, and commercial applicators who are interested in current advances in noxious weed management. Participants are required to move through the levels sequentially.

Level 1 in the series was first offered in April and October 2012 and will be offered again in early October 2013. Topics range from very basic plant biology and ecology to applying weed management tools and social aspects of weed management.

Level 2 in the series was first offered in April 2013 and will be offered again in April 2014. Topics from Level 1 are expanded upon in the classroom and in the field.

Level 3 in the series is still under development.

Faculty and staff from various departments and Extension at Montana State University are developing and hosting these workshops. The program was launched with help from a grant from the Montana Noxious Weed Trust Fund.
