FORECAST SUMMARY: Wednesday, May 5:
Disease Update - Friday, April 30: Blue mold has been confirmed in southern Texas. Dr. Bill Nesmith informs us that a team of plant breeders from the University of Kentucky observed wild tobacco growing in the region from Uvalde south to the Rio Grande River. They reported low populations of N. repanda. However, all of it was infected with blue mold and sporulating heavily. We will add a site from the Uvalde area to the forecasts on Monday. It will be combined with the one for Corpus Christi to describe the source region of southern Texas. We would have added the site today, but problems at Air Resources Laboratory interrupted the process before we could get the Uvalde trajectories generated.
Wednesday and Thursday: All sources are Low Threats, with Low Risk to the U.S. productions regions. Trajectories do not approach other growing areas. Strong high pressure over the southern U.S. will maintain a firm grip on the weather for the next several days. Unfavorable conditions for survivable transport and deposition will dominate in most locations.

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so. Please consult the Extension Service personnel in your area if you have concerns about these matters! *****
