[vc_row][vc_column][vc_column_text]Flooding across a street in Newark DelawareWith a powerful hurricane coming toward the Eastern United States, and more tropical depressions in the Atlantic, now is a good time to think about weather preparedness. Check weather updates on local news, the National Hurricane Center website https://www.nhc.noaa.gov/, or https://www.udel.edu/udaily/.  Make a plan today. Your family may not be together if a disaster strikes, so it is important to know which types of disasters could affect your area; hurricanes, flooding, tornadoes, etc.  Know how you’ll contact one another and reconnect if separated. Establish a family meeting place that’s familiar and easy to find.

  1. Put together a plan, know where it is
  2. Consider specific needs in your household
  3. Fill out a family emergency plan document
  4. Practice

The final report for the UD Plant Diagnostic Clinic for 2015 has been posted and can be viewed at the following link:
Final Delaware Plant Diagnostic Clinic Report 2015 2_10_2016
The Plant Diagnostic Clinic at the University of Delaware is housed in the Department of Plant and Soil Sciences, and is located in Townsend Hall, Room 151. The clinic serves the public through Delaware Cooperative Extension, directly serving commercial growers, crop consultants, nurserymen, landscapers, public gardens, and private homeowners. Samples are also received through county offices, from Extension specialists, and the Master Gardener Program. The clinic is the National Plant Diagnostic Network (NPDN) laboratory for Delaware, and the survey laboratory for Delaware Department of Agriculture and USDA/APHIS CAPS for Delaware. The clinic operates with one full-time staff, the Plant Diagnostician, cooperating with the Extension Plant Pathologist and the Ornamentals IPM Specialist in Entomology, and numerous Extension personnel.
During 2015, the Plant Diagnostic Clinic processed approximately 630 non-survey routine clinic samples. A National USDA/APHIS PPQ CAPS karnal bunt survey in cooperation with Delaware Department of Agriculture for wheat seed samples from all grain elevator processing stations in Delaware included five composite aliquot samples. All samples examined for the presence of karnal bunt were negative, ensuring the safety of the Delaware wheat crop for trade and export. Nursery surveys for Delaware Department of Agriculture resulted in a few samples of boxwood and chrysanthemum. Other samples were diagnosed in field situations, and not brought in for analysis. Phone inquiries and e-mail requests for information accounted for undocumented samples in addition to physical specimens submitted to the lab. The Ask an Expert service through eXtension.org included 69 questions answered by the Diagnostician in 2015. Over 50 % of the total questions answered via Ask an Expert for Delaware involved trouble-shooting of possible disease issues. Some trouble-shooting samples for possible nematode infections were processed in the lab, but are not included in this report.... see link for full report and data.

Ag Day was cool weatherwise, but a warm atmosphere for the crowds who came out to learn about and purchase plant, and see the other exhibits. It was a great day. I enjoyed being side-by-side with the Master Gardener Telephone and Diagnostics Team, and having Kayla help me at the Plant Diagnostic Clinic table!
Great to have student Kayla involved

SATURATED SOIL can lead to problems with roots of trees and shrubs, and ultimately contribute to death or uprooting of trees. When soil becomes saturated through over-watering or heavy rains, plants cannot develop new fine feeder roots that are responsible for uptake of nutrients. A good root system also anchors a plant well into the planting site. Development of a good root system can take time, and over-watering can prevent root growth and establishment. Plants with an under-developed root system are more prone to stress and root disease. Subsequent stress from drought that may occur later in the season can lead to death of plants that do not have a good root system. Trees and shrubs without a good root system are more prone to upheaval and toppling during storms with wind. Proper planting and soil preparation with good drainage may prevent problems in the future.

Saturated soil can also lead to problems in row crops, field crops, vegetables and turf. Good drainage can help  to avoid problems with root rot that may move in following flooding and saturated soil.
