"From the Network" News

Welcome to the New PMN Update!

As before, PMN Update features the latest content from the Plant Management Network--but now with a new look and easier navigation. Two features you should especially take note of include the following.

  • The “In This Issue” area at the top can instantly take users directly to a particular section, such as “PMN Crop News” or “Featured Journal Articles”.

  • The new one-column format and white background allow for a cleaner, more consistent look across multiple devices, browsers, and email platforms.

Important Login Advice for Personal Subscribers

PMN has a new authentication system that ensures individual PMN subscribers can still access Applied Turfgrass Science, Forage and Grazinglands, and Crop Management, which are still available through PMN but are located on a new platform. Individual subscribers are strongly encouraged to log in through before going to these three journals. At the PMN portal homepage and elsewhere on the website, users can click on the “Login” link in the upper left-hand area of the screen.
