Soybean Cyst Nematode Workshop

Thursday, May 6th, 2010

Tuesday, August 3, 2010  8:30 a.m.- 1:30 p.m.
Delmarva Poultry Industry Building
(former UD office building)
16684 County Seat Hwy.
Georgetown, DE 19947

Soybean cyst nematode (SCN) is a widespread and serious pest of soybeans on Delmarva. First discovered in the fall of 1979 it has been causing increased problems for growers in recent years. This workshop will cover some basics about the biology of SCN and it management and the results of the recent Delaware Soybean Board sponsored survey of SCN in Delaware. The workshop will also include visiting a small research plot to see SCN first hand and discuss symptoms, diagnosing SCN from root samples with a hand lens, and proper soil testing procedures. The workshop is suggested for agricultural professionals on Delmarva who advise soybean growers and growers who want to know more about this important pest.

Pesticide recertification credits and CCA credits in pest management will be offered for attendees.

The cost of the program is $10 per person with lunch included. The registration deadline is Friday, July 23. A registration form is available here:

Grain Marketing Highlights

Fast U.S. Planting Pace May Detour Seasonal Price Increases
We are nearing the time period, late spring to mid-summer, when corn and soybean prices have a seasonal tendency to trend higher. This phenomenon generally results from uncertainties concerning crop size until the corn and soybean crops get beyond their respective critical growing stages, this year likely to be around June 1 for U.S. corn and maybe August 1 for soybeans. However, there is some speculation that this year may turn out to be different from the norm due to planting progress. For the week ending May 2, the U.S. corn crop was nearly 70 percent planted as compared to only 32 percent last year and the five year average of 40 percent. U.S. soybeans were reported to be 15 percent planted compared to 5 percent last year and the five year average of 8 percent. The rapid pace of planting could mean that farmers plant even more corn than the March 31 Planting Intentions report indicated.

Global Factors Impacting Commodity Prices
As if the fast planting pace isn’t enough to cast a shadow over seasonal price tendencies, the Dow has taken a beating this week due to financial concerns across the globe, notably Greece. Apparently, the International Monetary Fund will be stepping in to aid Greece and, hopefully, stave off bankruptcy. However, this does mean that the cost of doing so will fall upon the tax payers of the countries affiliated with the IMF. The primary IMF contributors are the U.S., Japan, and Britain.

After increasing for the past few months, crude oil prices are in the process of crashing in yesterday’s and today’s trading (Wednesday, May 5). Interestingly, this is happening during the BP oil leak in the Gulf of Mexico that is currently threatening the seafood, tourist, and many other industries along the U.S. Gulf Coast. So what is the reason for the sudden crash in crude oil prices? One reason being suggested by a reliable source might be contracting demand in the U.S. and world economies.

China is in the market to import as much as 500,000 metric tons of corn this year. China will become a net importer of corn this year, first time in eight years.

The Southern Hemisphere will be completing their harvest very soon. USDA’s May 11 supply and demand report will either peg South American production as unchanged or increased from last month’s estimate.

Market Strategy
At this time of year, it takes a wild guess (sometimes referred to as a wag) to determine whether to advance crop sales or not? Weather conditions, although nearly ideal at the present time, don’t mean much concerning the final outcome for 2010 U.S. corn and soybean production. Although a lot can happen to change market direction between now and summer the picture isn’t looking very price positive for either corn or beans at the moment. Therefore, the best advice concerning whether one should advance new crop sales now or not is to pay attention to necessary price objectives based upon cost of production plus profit and act accordingly. Currently, Dec ‘10 corn futures are trading at $3.86; Nov ‘10 soybeans at $9.60; and July SRW wheat at $5.11 per bushel. In the case of SRW wheat one should look to price new crop sales for later delivery. For example, Dec ‘10 SRW wheat futures are currently trading at $5.45 per bushel.

Fields Not Treated Yet for No-Till Soybeans

Thursday, May 6th, 2010

Mark VanGessel, Extension Weed Specialist;

Due to the warm weather and good growing conditions, weeds in no-till soybean fields are larger than “normal” for early May. A few things to consider if the fields have not been treated yet:

● Coverage is important due to dense vegetation, keeping gallons per acre in the 20 gallons per acre range is important.

● While 2,4-D can help with some highly sensitive species (primrose), replanting intervals and proximity to sensitive crops will limit its use now.

● Don’t try cutting rates, weeds are large and often reduced rates will not effectively control them, even higher rates may not provide 100% control.

● Choose your herbicides carefully; if multiple species are present more than one herbicide will be needed and be sure they are compatible with one another, and they are going to provide benefit to your situation

● Be realistic in your expectations, controlling large dense populations of weeds is difficult, prioritize those species that are of the biggest concern. Remember a follow up in-crop application may need to be needed sooner than usual after planting to help control some species not killed by burndown treatments.

Water is Needed to “Activate” Soil-Applied Herbicides

Thursday, May 6th, 2010

Mark VanGessel, Extension Weed Specialist;

Herbicides applied to the soil surface require rainfall or irrigation to move them into the soil where the plants will absorb them; or they must be mechanically incorporated (field cultivator). With the lack of rain in most parts of the region over the past two weeks, we can expect reduced control. Some products like atrazine or mesotrione, maybe taken up by the roots and provide some control. But Dual, Harness, and Prowl all need to be absorbed by emerging shoots or do not translocate, so they will not controlled weeds once they emerge. If you have irrigation and your corn herbicides have been applied but you have not received water, you should consider irrigating to activate those herbicides.

Managing Compaction on Pastures when Soil Moisture Content is High

Thursday, May 6th, 2010

Richard Taylor, Extension Agronomist;

During the rather warm weather of this past weekend I spent a couple of relatively uncomfortable nights when our new air conditioner wouldn’t start. Although this can hardly be called earth shattering news, it did bring to mind how we all seem to have forgotten the days when AC was not available and wasn’t built into our tractors as standard equipment. Following the uncomfortable weekend, I was asked if it is important to consider how wet some pastures or areas of pastures are when choosing the tractor to use when dragging a chain drag across the pasture to break up manure piles. Although we might be tempted to use whatever sized tractor we have that has AC and all the comforts of modern equipment, it is important to keep in mind that we should use only as large and heavy a piece of equipment as is necessary to complete the job. In the case of dragging pastures to spread manure piles to prevent the piles from killing the grass/legume beneath them, a small tractor or ATV capable of pulling the chain drag is all that is needed.

Although grazing animals can contribute to compaction issues, I think it is good management to minimize all other sources of compaction. Mowing recently grazed pastures or dragging them to redistribute the manure are excellent practices in their own right. Mowing leftover spring grass removes seed heads and stimulates the grass to produce new vegetative tillers that are high in nutritive value. Spreading manure helps it to dry out and get into contact with more soil surface area to encourage rapid decomposition. Dragging manure spreads the nutrients over more land area and removes manure piles that can suffocate or shade out the underlying grass creating space for weed encroachment. When piles are not broken up and distributed around the pasture, animals selectively graze away from the grass in and around the pile causing reduced utilization of the pasture.

Choosing to use the biggest and perhaps newest heavy duty equipment can make the job of mowing or dragging pastures more tolerable but in the process of doing a good management practice you end up cancelling all the good you will be doing by causing more compaction problems, especially in the wetter areas of a pasture. Compaction, and especially deep compaction issues, are very difficult to resolve without a total pasture renovation in which the pasture is deep ripped, tilled, and replanted. Compaction issues tend to be cumulative until poor productivity or weed competition becomes severe enough to demand a solution — total pasture renovation. So, take out the sun screen or pull on a large hat, wheel out the four wheeler or one of the older, smaller tractors and avoid more compaction!

Hay and Pasture and Potash

Thursday, May 6th, 2010

Richard Taylor, Extension Agronomist;

Although it’s a little earlier than normal, I think it’s time to start thinking of applying spring potash (K) and phosphorus (P) fertilizer to your pasture and hay fields. For the hay fields, you will want to wait until after the first harvest, but I’ve seen a number of fields at heading (grasses) or late bud (alfalfa) which is a good time to harvest a good to excellent quality hay. For those more interested in tonnage, you’ll be holding off harvest for a few more weeks but you can still plan ahead for when your fields will be ready to fertilize with P and K and another shot of nitrogen (N). The warm weather of the past week and the period of very warm weather earlier this spring has orchardgrass and many other cool-season grasses heading out already. Early May is also, on average, a time when we have the greatest chance of a period of warm sunny weather long enough to dry hay.

Potassium or potash is a very critical element that helps plants tolerate the stresses of heat, drought, insects, and diseases that attack cool-season grasses in the summer. Although the price of K is high at the present time, the corresponding benefits of K fertilization will help you afford the cost of fertilizing with K. Many growers have chosen to either lower their K fertilization rates or eliminate them completely during the past couple of years when the price of fertilizer has been very high. If you have a current soil test, check the recommendations for how much K might be needed. If your soil test is not current you should get one as soon as possible to determine how much K you should apply or to see if the soil test levels are falling too rapidly.

In general if both P and K are needed by your hay or pasture field, add the P and half the K after the first hay harvest or in late-May or early June and then add the second half of the K recommendation in late August or early September. This timing will allow the plant to prepare for the stresses of summer and then for the stresses of winter.
