***** Disease Update - 3 September ***** We have two new sources of downy mildew to report. Downy mildew has broken out again on an experimental plot at the Coastal REC in Charleston, SC. This is a moderately serious infection in a 1-acre field of cantaloupe. Recent weather has been favorable in this area. Our thanks also to Steve Johnston in New Jersey.... who informs us of a moderately serious outbreak of downy mildew in winter squash near the town of Carney's Point in southwest NJ (Salem County). Weather conditions were unfavorable for most of the crop production period but have recently turned favorable. The field is being harvested at this time. Whether or not this field continues as a source post-harvest remains unknown.
