New Weed Science resources

A couple of new resources on weed identification and herbicide site of action from OSU weed science:

 - We have developed an iBook for weed ID, “The Ohio State University Guide to Weed Identification”.  This is a really nice resource to download onto an iPad or Mac computer for use in weed ID in the field or wherever.  It will not run on iPhone or other platforms.  The first edition of this is currently free on iTunes, but we will charge for the subsequent editions that will contain even more weeds.  Go to iTunes, and then search “weed identification” and it should come up. 

 - A collection of our time-lapse videos demonstrating herbicide mechanism of action is available on YouTube.  These are labeled with herbicide site of action number.  Search for “Ohio State Weed Science” in Youtube or use this link:
