^ Soybean rust symptoms in a commercial field in Liberty County. August 25,2006

^The kudzu had died back extensively by mid-December, 2005 and had completely died back by mid-January. The rust fungus can only survive on living plant material, so if the kudzu dies back, then the rust dies, too. The kudzu had started to grow back as of mid-March, 2006. No rust seen as of mid-April.

February, 2006 on soybean in Hidalgo County:
