Road Trip 07/13/16 Merritt Melancon
Like many other young people, plant pathology graduate student Russell Ingram’s friends have an epic road trip planned for this summer. The difference is that instead of setting off for a music festival in the desert or visiting a beach, Ingram’s pals are hitting the road in search of jobs.

This is a partially reconstructed point-cloud of a peanut field. When completed, UGA scientists will be able to tell the height, width, leaf cover, growth and disease anomolies for individual plants and track it through the season. Currently the research project is working to make the 3-d reconstruction accurate to within 1 mm. CAES News

Garden Plan 03/10/16 Frank M. Watson
This time of the year gardeners get excited about their soon-to-be-planted spring vegetable gardens. They envision lush rows of perfect pods of peas, scrumptiously delicious sweet corn and big, beautiful tomatoes. University of Georgia Extension urges gardeners to wait and put some thought and vision into their garden first.
Southern corn rust appeared at least two weeks early in 2014 (5 June) than it did in 2009, 2010, 2011, 2012 or 2013. Appearing earlier means that this disease will likely be more problematic than in recent years. Corn that is approaching (or has passed) the tassel growth stage is worth protecting if the yield potential is there, according to UGA Extension agent Shane Curry. CAES News
El Nino 2016 02/25/16 Clint Thompson
University of Georgia Cooperative Extension plant pathologist Bob Kemerait cautions Georgia corn farmers about the El Nino weather pattern that will likely interfere with planting this March. A delay would increase the likelihood of diseases too, so Kemerait advises growers to plant resistant varieties and be ready to apply fungicides earlier than normal.
