The weather this season is favorable to cause a blast epidemic. Get ahead of the disease! Rice blast pathogen spores can easily move across a field and/or from a field to another by wind.

Rice diseases in “underwater” rice
Author: Yeshi Wamishe, Extension Rice Plant Pathologist

Rice fields in some counties are “underwater “due to the excessive rain in the last days of June.  As I drove (07/02/14) in Monroe, Woodruff, and St. Francis Counties, I saw fields of soybean and rice covered with water (Pictures 1, 2, 3, 4).  Information on soybean conditions has been given at http://www.arkansas-crops.com/2014/07/02/flooded-replanting-considerations/. Though not […]

Air-borne spores usually infect young leaves. Spores from young leaves may infect collars, nodes, and panicles of rice. Sometimes when the first emerged leaves dry and die back, blast […]

Managing Flood-sensitive Disorders in Rice
Author: Yeshi Wamishe, Extension Rice Plant Pathologist
