Hi All. In my last blog the subject was about what I had learned regarding the use herbicides as a tool for effective passive restoration of CSS and native grassland habitats. As an Extension Advisor my job is to not only develop new information, but to also try to move it forward into practice.

After making a bunch of extension presentations, and following our 2012 publication of “Preemergent control of medusahead on California annual rangelands with aminopyralid” (Rangeland Ecology & Management 65:418-425), I’ve talked with quite a few ranchers who have successfully used Milestone® preemergence at 7 to 14 oz/acre to control medusahead. (See this blog post.) I should note here that 7 oz of Milestone is the maximum broadcast rate; 14 oz is labelled only for spot treatments.
Recently, Matt Rinella (USDA-ARS, Montana) found that aminopyralid controls seed set in medusahead in the greenhouse. He previously demonstrated this effect for...
