Another Brown Patch Sighting This Summer

Back in mid June Dr. Ron Strahan brought me a sample of active brown patch on St. Augustine from south Louisiana. Well, here it is the middle of July and Gerald Roberts, county agent in Lafayette Parish, also notified me of an active brown patch sighting. I wanted confirm this first hand and collect a sample to get an isolate for future reference, so I headed west this morning. Sure enough, it’s brown patch! Apparently the trees surrounding the yard are keeping it cool enough, and it’s been wet enough recently for disease to develop. As Dr. Ron tweeted back in June, “Crazy year!”

    does brown patch infect Asian Jasmine? In the asian patch at my house it started as a crescent and over two months has progressed. The leaves just die, the roots look OK. the Jasmine is under heavy oak tree shade.
