Volume 9, Issue 27 September 28, 2001
This is the Last Issue of Weekly Crop Update for the
2001 Season.
I hope that the information that you received this season has been helpful and relevant. This newsletter would not be possible if we did not have the dedication of many people who put the information together for the newsletter each week.
As editor, I would like to express my sincere thanks to
those individuals that contribute.
Please do not hesitate to express your comments and suggestions for improvements for Weekly Crop Update to any member of Delaware Cooperative Extension.
Best Wishes for a safe and prosperous harvest season. I look forward to interacting with many of you during the winter meetings.
Regards,
Tracy Wootten

Lima Beans.
Downy mildew continues to be found, but not at last years level. Keep scouting late maturing fields. Fungicide applications appear to be working, hopefully because fields were sprayed preventatively and its been a little drier.
If you find downy mildew we are still interested in determining the race of the fungus present. Please take samples to the county Extension offices. Wrap the infected pods in paper towels and place in paper bags and refrigerate until transported. Label the bags with the location and variety grown.
Phytophthora capsici was identified last week in a field of Cypress. This was originally identified as downy mildew. It can be easy to confuse the two diseases so be sure you have downy before applying a fungicide. For crop rotation and planning purposes also it will be important to know what is present to avoid planting a susceptible crop such as pickles, peppers, or watermelons.
Anthracnose is also present in many fields at the present time. Infected leaves have small (up to 1/2 inch), irregular dark, rusty brown spots. Rotations of two years or more will aid control.
Snapbeans.
Rust is present in some late fields. Scout regularly and spray with Nova or Bravo (chlorothalonil) when the disease first appears.
Nematodes in Veggies.
Fall is the best time to soil sample for nematode pests such
as root knot, lesion, and other plant parasitic nematodes. After fall harvest,
but before any fall tillage is done take soil cores six inches deep between
plants in the row. Samples should be taken in the root zone of the old crop.
Twenty cores/ sample should be taken from random spots in the field and placed
in a plastic bucket gently mixed, and a pint of soil submitted for analysis.
Nematode test bags and instructions are available for purchase from the county
Extension offices. Samples cost $10.00. Fall
sampling for root knot nematodes is strongly recommended for fields that will
be planted in cucumbers, watermelons, cantaloupes, lima beans or other high
value vegetables where root knot could reduce production.
Fall Sanitation.
In vegetable production, it is not a good idea to leave old
crop residue in the field any longer than necessary. If the crop is allowed to
survive after harvest, fungi that cause diseases continue to increase on the
surviving plants. This allows higher numbers of the fungus to potentially
survive until next season. Sanitation (plowing or disking the old crop) will
help prevent pathogen carry-over.
REMINDER for Pesticide Storage
Always keep pesticides locked in a secure storage facility. You are encouraged to keep a complete inventory of materials on hand for verification of material use. At this time, it is important to keep all hazardous materials out of the hands of those who would use these chemicals against us.
The
University of Delaware will be offering the following Nutrient Management
certification sessions. The following is a brief summarization of your
certification needs:
·
Sessions must be taken in order.
For example, you must attend Session I before attending Session II.
·
Poultry
growers that do not apply manure will need to attend Session I and Session II:
Poultry.
·
Livestock
producers that apply nutrients to crops will need to attend Session I, Session
II: Other Animal, and Session III: Private Nutrient Handler
·
Grain
or Vegetable producers that apply nutrients to crops will need to attend
Session I, Session II: Non-Livestock, and Session III: Private Nutrient Handler
All
certifications must be completed by January 1, 2004. Once you begin the certification process the Delaware Nutrient
Management Commission asks that you finish your certification within a
year. There is an estimated 5,000
people in the state of Delaware that need to be certified. Please sign up early to get the session you
would like to attend because the session size is limited. We will be adding more sessions as these
fill. Session dates may be cancelled if
a minimum of 20 people are not signed up. To sign up for sessions, please
contact your local county extension office.
