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.

Vegetable Diseases

Extension Plant Pathologist; bobmul@udel.edu
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.

Diseases - -
Bob Mulrooney, Extension Plant Pathologist; bobmul@udel.edu
Small Grains.
Be sure that you plant wheat varieties with high levels of disease resistance. Seed should be treated to protect them from loose smut and common bunt. Varieties that are susceptible to powdery mildew should be treated with Baytan or other seed treatment that will protect them from early infection.
Soybeans.
Do not ignore soybean cyst nematode. It is still present and in spite of the wet season and good growth of soybeans this season, SCN can be present in high numbers as well. The wet season has helped plants compensate for nematode damage, which lulls growers into thinking that everything is fine because they see no severe stunting. During wet seasons SCN numbers can increase dramatically on susceptible varieties. Some late season troubleshooting samples have shown that SCN was responsible for poor growth (short plants) in some fields. Soil sampling after harvest before any fall tillage is recommended for fields to be planted next season to soybeans following this years crop. Soil sample bags are available from the county Extension offices for $10/ sample bag.

Grain Marketing Highlights - Carl
German, Extension Crops Marketing Specialist; clgerman@udel.edu
Commodity Prices Respond to Harvest Pressure
The primary factor impacting U.S. corn and soybean prices right now is the
rapid pace of harvest progress, which is imposing pressure on harvest
prices. U.S. farmers are expected to harvest large, not quite record,
corn and soybean crops at 9.238 and 2.834 billion bushels respectively. Reports
are coming in from Midwest farmers that are indicative of very good to
excellent yields and harvest progress being made that is likely ahead of normal
progress for this time of year.
The likely impact of the early and rapid harvest pressure on corn and soybean
prices is lower from current levels, 10 to 20 cents per bushel for December
corn and 15 to 40 cents per bushel for soybeans. Therefore, it may prove to be
good business to wait for the harvest pressure to work through before taking
any speculative positions in the market.
Marketing Strategy
Farmers with on farm storage are going to need to consider placing unpriced
grain at harvest under the loan. Those without on farm storage are likely to
take the cash sale, the deficiency payment, and then consider either placing
the money on an interest bearing account or maintaining staying power in the
market with the purchase of call options. In the event the call option strategy
looks probable, it then becomes imperative to pay attention to commodity price
level (now indicated to be moving lower), the premium cost of the option, the
impact on the net cash price received, and the strike price of the option.
With this being the last issue of Weekly Crop Update for this season, grain
marketer's are invited to continue receiving 'Grain Marketing Highlights' via
the Internet Grain Marketing Discussion Group. In order to participate in the
Grain Marketing Discussion Group, send a message to < majordomo@udel.edu > with the only

Observations Made During Corn Yield Checks Derby Walker, Agricultural Agent, derby@udel.edu
Currently, 19 corn yield checks for the National Corn Growers have been completed. The following are commonalities for high yielding corn fields:
1. Good drainage and timely irrigations.
Too much water hurt corn yields, especially irrigated fields. What are high yields? Irrigated 220 to 240 bu/A, dry land 180 to 200 dry bushels of corn/A.
2. Uniform plant stand (plants evenly spaced and all emerged at the same time).
Late emerged plants had small ears, if they had any ears.
3. The early-planted corn had the highest yields. Yields have decreased with the later plantings.
4. Timely harvest with properly set machines.
As the moisture dropped below 20%, field losses increased. Field losses more then doubled by waiting. Some growers drive too fast or have incorrectly set their machines leaving grain in the field. In several fields, there would have been harvest problems because of stalk and root rots. The combination of a good harvest season and timely harvest has prevented field losses. Growers should harvest fields infected with stalk and/or root rots first. Early harvest prevents high field losses. It is easy to check for stalk and root rots. Grab the lower stalk, if it collapses it has stalk rot (100 plants to determine %). Pull the stalk; if plants easily come out with a little root ball, you have a root rot. Under wet and windy conditions, this corn will fall over. Harvest it before it does.
5. Nitrogen rates
200 bushels of irrigated corn can be grown with 200 pounds of nitrogen when nitrogen is put on in a timely fashion. To get higher then 200 dry bushels, more nitrogen is needed. However more nitrogen cannot over come plant stand, irrigation or drainage problems. On dry land, it is rainfall that determines yield, not nitrogen rates.
6. Variety performance should be taken into consideration when making plant population decisions.
Some varieties have more disease problems when they are crowded together.
7. Match the variety to the soil borne disease problems in the field.
This may mean selecting a variety with less
yield potential, but it may out yield higher yielding varieties because it can
handle your disease issues.
