FORECAST SUMMARY: Thursday, April 17:
*** Disease Update - 15 April *** New reports of Downy Mildew from deep South Texas. Both are in Hidalgo County in fields of Matagua cantaloupe. One outbreak, characterized as moderately serious, lies southwest of the town of Hidalgo along the Rio Grande. Another outbreak, this one quite small, is in a field near Edinburg. No spores were seen and the infection looks to be dead and non-spreading. Various treatments have been applied at each site. The source along the Rio Grande will be added to our forecast rotation. Our thanks to Rick Hernandez for these reports.
*** Low Threat from the southern FL source region during the next 4 to 5 days. The Texas source will threaten areas to the north on Friday, and conditions will probably remain mixed for disease development in southern TX through Monday. *** In the Southeast.... several frontal systems are impacting the region during the period. However, the bulk of the rainfall and active weather will remain well to the north of the source region. Trajectories do not approach other growing regions for at least the next three days. Conditions near the source will be only slightly favorable (i.e., mostly unfavorable) for disease development. Weakly Moderate Risk for southern FL cucurbit crops Thursday through Saturday.... and probably through Monday. In Texas.... Low Threat today due to unfavorable transport conditions. As a front moves through the state Friday and Saturday, mixed conditions for survivable transport and deposition are expected. Friday... Moderate Risk to cucurbit crops in much of central and western TX and OK. Low Risk Friday in far west TX, the TX/OK panhandles, eastern and southeastern TX, down through the coastal bend. Saturday.... Moderate Risk for deep south TX, the coastal bend, and the Rio Grande plains. Low Risk otherwise.
