The featured speaker will be Clif Parker, recently retired Assistant Deputy Administrator with the USDA Risk Management Agency (RMA). During his career with RMA, Mr. Parker worked with many aspects of the development and administration of federal crop insurance.  His inside perspective will be of interest to Delmarva farmers preparing to make crop insurance decisions prior to the March 16 sales closing and policy change date.

The latest information on Crop Revenue Coverage, Group Risk Plan, Group Risk Income Protection, and traditional Actual Production History coverage will be presented. Discussions will include how to use crop insurance to optimize your potential benefits under the new Supplemental Revenue Assistance Program (SURE) administered by the USDA Farm Service Agency.

The USDA Risk Management Agency has announced the following for crops covered by Crop Revenue Coverage (CRC) and Group Risk Income Protection (GRIP). Coverage and premium examples for these crops will be covered during the Pre-Deadline Crop Insurance Workshop

Time to Employ a Defensive Marketing Strategy

Friday, March 6th, 2009

Carl German, Extension Crops Marketing Specialist; clgerman@udel.edu

What is defensive marketing? Defensive marketing is taking the necessary steps to be able to weather the storm given the extreme uncertainty being depicted in the commodities and financial markets for the remainder of the 2008/2009 and 2009/2010 marketing years. Blanket recommendations concerning marketing decisions seldom serve the individual well. However, this cropping season is different from the recent past and from a historical perspective.

During the winter, under more normal conditions, commodity prices (corn, soybeans, and wheat) would have been expected to bounce from price levels that were set in mid-December or even early January. Instead, due to economic conditions in the U.S. and abroad, the most recent low for November soybean futures was posted on March 2nd at $7.89 per bushel. New crop December corn futures, last traded at $3.89 in the overnight e-trading session just 40 cents above the most recent low of $3.49 made in active trading on December 5th. The primary driving force in commodity trading over the last two months has been the fate of the general economy reflected in the Dow Jones Industrial Average. In mid-December, the Dow was trading near 8700, in early January near 8980, and 6760 on March 2nd. The 7099 support level was broken last week, representing a 50% retracement from the 14,200 high. The next level of support for the Dow is at 4600, a 67% retracement from the high. If the Dow heads to the next level of support then we can be assured of a further decline in commodity prices.

2009/2010 Marketing Strategy
1. Consider buying crop insurance. You must have crop insurance in one form or another to be eligible for SURE (information on SURE is available at your FSA office). Crop insurance is not a panacea that can fit everyone’s needs on every farm and every crop. However, it can prove to be very beneficial for some crops on some farms, particularly when proven yields on the farm are well above the county or state average yields or when a crop disaster occurs. For CRC and GRIP crop insurance policies the price guarantees are now set at $4.04 per bushel for corn and $8.80 per bushel for soybeans. The deadline for crop insurance is March 16th.

2. Visit your FSA Office. Make sure that everything gets done that needs to be given attention. Consider entering FSA’s Acre program or opt to stay in the old DCP program.

3. Watch for opportunities to cover unprotected intended production via forward cash contracts or the purchase of put options. Remember, crops covered by CRC present one with an opportunity to price those crops at higher levels than the price guarantees. In other words the CRC covered crops place a price floor under the insured portion of your crop.

4. Bear in mind that every bushel of your intended production must be marketed or sold. Do not over contract intended production.

5. Plan to store a portion of your 2009 crop production. The crop size for the 2009 growing season will determine whether pricing opportunities prevail this summer and fall. If a huge crop is grown in the U.S. this year, coupled with a contracting economy, we could see commodity prices moving to the loan by harvest. Current circumstances require that one prepares for the worst of outcomes and hopes for the best.

Concerns with Some Chickweed Populations

Friday, March 6th, 2009

Mark VanGessel, Extension Weed Specialist; mjv@udel.edu

Scott Hagood, extension weed specialist from VA Tech, has identified four fields from Virginia (across the bay) that had common chickweed that was resistant to Group 2 herbicides (this includes Harmony, Harmony Extra, Finesse, and others). Likewise, we have had reports of fields on Delmarva with chickweed populations not controlled with Finesse or Harmony Extra. We are investigating this in the greenhouse and have no answers yet as to why the chickweed was not controlled.

However, if you have fields with poor chickweed control and do not feel Harmony or Harmony Extra are performing as they should, your alternatives are quite limited. Other small grain herbicides that we are familiar with do not provide acceptable chickweed control. One product to suggest is Starane Ultra (from Dow AgroSciences). This product is labeled for wheat and barley and has been used in the western US for control of Group 2 resistant weeds. Local data is lacking on its performance, but it appears to have good crop safety and good chickweed control. However, it will not control other key species such as wild garlic. Starane Ultra can be tankmixed with Harmony Extra to broaden the spectrum of control. Starane Utra by itself does not need an adjuvant and can be applied in nitrogen. Be sure to read and follow label directions.

Small Grain Weed Control

Friday, March 6th, 2009

Mark VanGessel, Extension Weed Specialist; mjv@udel.edu

If you did treat your fields in the fall for weed control, is time to be scouting the crop. Weed control is important to achieve maximum wheat yields. There are a number of good herbicides for small grains, provided they are used at the proper timing. Weeds need to be small (less than 2 inches in height or diameter) and actively growing. This often requires a separate application for herbicides since this often does not coincide with nitrogen applications. Often weeds are not actively growing during the first nitrogen application and then weeds are too large (and wheat interferes with herbicide coverage) at time of the second nitrogen application.

Fields that were no-tilled or where chickweed emerged shortly after planting in the fall are fields to check first for spring treatment. If you have wild garlic or Canada thistle, the time of application should be delayed since you need to spray these weeds when they have fully emerged. Yet, coverage is important for these species; so allow adequate emergence, but do not wait too long. If weed pressure from winter annuals is great, it may not be possible to get control of the winter annuals and perennials with one application. In that case, two applications may be required.

Harmony Extra can be applied with nitrogen. If spraying Harmony Extra with nitrogen, be sure to pre-mix it in water first. If using nitrogen as your carrier, there is no need for a surfactant unless you have wild garlic and it is over 8 inches tall. If applying Harmony Extra in nitrogen diluted with water, use a non-ionic surfactant at ½ to 1 pint/100 gallons of solution. If applying it in water use a non-ionic surfactant at 1 qt/100 gallons.

There are various formulations of Harmony and Harmony Xtra as well as generic brands. Be sure to read the label so you have the correct rate. Also, remember the TotSol Formulation from DuPont requires extensive mixing to fully dissolve the granules.

Grass control in small grains is still challenging, even with a few new products. Hoelon is the only product labeled for grass control in barley, and it will only control annual ryegrass before it is more than 2 tillers. For winter wheat, Osprey is also available. Fall will be a better time for Osprey applications, but it will control annual ryegrass in the early spring. Osprey cannot be applied with nitrogen carrier and the Osprey application and nitrogen application must be made 14 days apart. Spray solution can not be any more than 15% liquid nitrogen. Osprey has activity on small annual bluegrass. If Osprey does not fit into your situation because of the nitrogen applications, Axial XL has shown good results with spring applications. However, Axial XL will not control other grass species.

Finally, the following are the timing limitations for small grain herbicides. The timing restrictions are based on crop safety.

● 2,4-D – up to jointing stage (pre-jointing)
● Banvel/Clarity – up to jointing stage (pre-jointing)
● Osprey – up to jointing stage
● Buctril – up to boot stage
● Harmony Extra or Harmony GT – up to flag stage (pre-flag leaf)

Changes to the Format of the Insect Section of the Commercial Vegetable Production Recommendations

Friday, March 6th, 2009

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

In the 2009 edition of the Delaware Commercial Vegetable Production Recommendations, you will notice a number of changes agreed upon by the entomologists from the five-state region that work collaboratively on this publication. These changes include:

1. Common names for insecticides now listed in book – As I am sure you are aware, chemicals (including pesticides) have scientific names based upon their chemical structure (i.e. the chemical name). In many instances, these chemical names are long, complicated and understandable only by those with a technical background in chemistry. Therefore, EPA encouraged the development and use of “common names.” The common name of an insecticide is the name given to an active ingredient and it is used in lieu of the chemical name on a day-to-day basis. In many cases, insecticides with the same common name are sold under numerous trade/brand names. A number of years ago we started to list Ambush and Pounce as permethrin (the common name for both products) because there were a number of other “generic permethrins” in the market place. A more recent example is the availability of numerous trade/brand names with the same common name — bifenthrin (examples include Bifenthrin, Brigade, Capture LFR, Sniper, and Fanfare). With the increase in the number of generic insecticides and mixtures of compounds containing older chemistry as well as new chemistry, it became extremely difficult to include all of the trade names and rates for any one insecticide. Therefore, we decided that it would be more useful to list the common names with a few examples of the more available trade/brand names in parenthesis as well as “OLF” to denote that “other labeled formulations” are available.

2. Rates Removed - It also became apparent that, in a number of cases, different generics with the same common name are labeled on different crops. In other cases, different generics with the same active ingredient have different formulations so the rates are different. In addition, a number of the new combinations of generics are using different rates compared to the original rates of stand alone chemistry. The only way a producer or applicator can choose the correct product and rate is to read the label. A combination of all of these factors resulted in a decision to leave rates out of the 2009 edition. Labels are always changing so it is important to read all labels on the pesticide container before applying any pesticide. In some cases, the labels you find online or even in label books may not be the most recent label or may have changed after printing.

3. Restrictions – A number of years ago, we removed the restriction box from the recommendations because of the increasing number of new or different restrictions on labels relating to use patterns, resistance management, rotations etc. Since the label is the law, it is critical that the user read the label to be aware of all restrictions as well as the correct use rate.

If you have any questions about these changes, please feel to contact Joanne Whalen at 302-831-1303 or send an e-mail to jwhalen@udel.edu.
