The 3MT® - Three Minute Thesis Competition is a research communication contest, which challenges graduate students to present a compelling oration on their research and its significance in just three minutes in language appropriate to a non-specialist audience.

 On April 16th Katie McCauley competed against the top 11 Three Minute Thesis PhD and MS students at Oklahoma State University in the Graduate College finals. We are proud to say that Katie brought home first place with her thesis topic: “Improving the overwintering capability of winter canola”.  She won a $1,000 cash prize and will represent OSU at the Regional University finals in Charlotte, NC in February 2016.  Way to go Katie!

Diagnostic service to test for herbicide-resistant weeds

Herbicide-resistant weeds is one of the many issues that producers are now facing throughout Oklahoma and the United States.  Early detection of populations of herbicide-resistant weeds will give a head-start to management and prevention of their spread.  At OSU, we have started a new diagnostic service program that allows for producers, crop consultants, and extension educators to submit weed samples for testing to determine if the weeds are resistant to certain herbicides.  This program is funded in part by the Oklahoma Peanut Commission, the Oklahoma Soybean Board, and the Oklahoma Wheat Commission and will be provided as a free service to anyone involved in Oklahoma agricultural production.

The fact sheet,  PSS-2779 “Diagnostic Service to Test for Herbicide-resistant Weeds in Oklahoma,” gives instructions for collecting and submitting seed samples.  The seed samples do not need to be threshed and cleaned, but it is important to collect enough seed for adequate testing (typically, enough to fill half of a paper lunch sack).

If you have any questions, please contact your county OCES agricultural educator or Angela Post, OSU Extension Weeds Specialist, at (405) 744-9588 orangela.post@okstate.edu  for more information.
