In this trial we asked cooperators to assess the potential of molybdenum containing seed treatment. In the past we have observed some visual differences with the use of molybdenum seed treatments and small 1-3 bu/acre yield responses.  On this field the molybdenum treated strips were apparent in aerial photography (upper right, compliments of Google Earth) throughout the season.  Over the five replications of this very high yielding study, we measured a 2.3 bu/acre yield difference, which was significant at the 0.24 level. These results are consistent with other field scale and small plot studies that we have conducted and suggest that in some environments there may be small advantages to using a molybdenum seed treatment.

Inexpensive all broadleaf control in pasture

Del Voight- Penn State Extension

The 2 quart rate of the Name brand Crossbow is a great herbicide to clean up pastures of numerous weeds. Many growers are just too tight to spend the money on it.   The price per acre however is expensive. Somewhere in the $25.00/acre range.  We then have to retreat areas again and again. Here is one option I worked on this summer.
I make up my own mix of Triclopyr 4 plus 2,4-D Ester
I use  1 pint of triclopyr 4 per acre and 1.5 quarts per acre of 2,4-D ester and apply it in 20 gallons of water per acre. This gets my costs to around $8.75/acre for the mix. This means you will need to mix two products at each fill up. Not a big deal considering the cost difference.  If you can afford you can use the Crossbow or Candor or numerous generics of the orginal Cross bow but if you use this mix do not ask Dow to help if you have a failure. This is all subject to conditions. I lean this way since if I have alot of brush I can increase the triclopyr in the mix to ensure good knock down.

Fall Herbicide Applications — Del Voight Penn State Extension (in consultation with Dr. Bill Curran Penn State and Mark Loux, Ohio State University)

As I traveled the area the last two weeks I have run into numerous growers inquiring about fall applied herbicides.  One grower had stopped planting his cover crops and decided to look into set up programs for his corn or beans in the spring.  Most prefer to put something down now that would enable them to plant either corn or beans into the area in the spring.  Bill Curran relates the following:  Concerns we have here in Pennsylvania with fall herbicide applications are: 1.)  Will a clean field leave it open to erosion and soil loss over the winter? This is less of a concern for corn grain going to soybeans, but could be a concern for recently harvested corn silage ground and overwintering soybeans stubble. 3.) Is this strategy cost effective and do you have a valid reason for doing it? See the comments that follow, but in the end, fall weed management will depend on a number of factors where some fields are more appropriate for this strategy than others.
Mark Loux at OSU recently emphasized these summary points:
  1. The primary reasons for fall application is for control of an existing infestation of winter annuals or marestail, or control of biennials (wild carrot, poison hemlock) or perennials (dandelion, quackgrass, Canada thistle) that are most susceptible to herbicides in the fall; low populations may be adequately controlled with spring burndown treatments. The primary value of fall herbicide treatments is control of weeds that have emerged by the time of application, which typically results in a weed-free field next spring, or at least until sometime later in April. This can be accomplished with about $4 to $12 worth if herbicide.
  2. The core group of herbicides that will control emerged weeds when applied in the fall include the following:
·         Soybeans  Set Up programs for next spring
o   Canopy EX or DF + 2,4-D – can be used prior to soybeans.  The only one of the treatments listed here that provides residual control into the following spring/early summer.  The lower labeled rates of Canopy are adequate for control of emerged winter annual weeds.  Canopy DF may not adequately control chickweed unless mixed with glyphosate, metribuzin, or Express.  Canopy treatments have been the most effective for control of dandelion.
o   Glyphosate + 2,4–D
o   Metribuzin + 2,4–D (excluding dandelions)
o   Sharpen is also labeled prior to soybean.  Must be applied prior to the first killing frost.  Mostly a marestail program.
o   Numerous Authority Products are also available in this market and listed in the Agronomy Guide
·         Corn set up programs for next spring
o   Basis + 2,4–D
o   Glyphosate + 2,4–D
o   Simazine + 2,4-D – can be used prior to corn.  It controls winter annuals only.  While simazine is a fairly persistent herbicide, it provides little residual control into the spring.
o   Numerous other options available in the Agronomy Guide
·         Corn or Soybeans next Spring
o   Metribuzin + 2,4-D – can be used prior to corn or soybeans.  This mixture controls winter annual weeds only.  The metribuzin can provide some residual weed control into later fall, but residual control does not persist into the spring.
o   Autumn + 2,4-D or glyphosate – can be used prior to corn or soybeans.  Controls winter annual weeds and can suppress dandelions, but overall is not as effective as Basis treatments.  The 2,4-D or glyphosate carries more of the load for this treatment compared with the others shown here, so higher rates of these herbicides maybe required.
o   Express + 2,4-D – can be used prior to corn or soybeans.  Controls winter annual weeds and dandelion, but less effective than Basis or Canopy treatments on the latter.
o   2,4-D + dicamba (premixes = Weedmaster, Brash, etc) – can be used prior to corn or soybeans.  This combination controls most broadleaf weeds, but is not as effective as glyphosate-based treatments on dandelion or Canada thistle.  In OSU research, application of dicamba alone has not typically provided adequate control when applied in November, but the combination of the two herbicides seems to work.
o   Basis + 2,4-D – can be used prior to corn, and also prior to soybeans south of I-70 at rates up to 0.5 oz/A.  This combination is effective on winter annuals and dandelion, with some activity on biennials.
o   Glyphosate + 2,4-D – can be used in the fall prior to any spring crop.  It is the most effective of the treatments shown here on grasses, biennials, and perennials.  The combination of 0.38 lb ae/A of glyphosate plus 0.5 lb 2,4-D ester is effective for most winter annuals, and rates of both herbicides can be increased for perennials and biennials or large weeds.
Some other herbicides not listed above can also be used, but their utility is no better and not as good on dandelion as those mentioned above. Glyphosate + 2,4–D is the most effective for control of most perennial and biennial weeds, and glyphosate can be added to the other treatments to accomplish this. Combinations of 2,4–D plus Canopy or Basis have been the most consistently effective on dandelion.
  1. Among all of the herbicides mentioned above, only Canopy products provide substantial residual control of annual weeds that emerge in spring or early summer.
Mark emphasizes that in most soybean fields, it is a big mistake to apply all of the residual herbicide in the fall, with the goal of making only post emergence glyphosate applications the following year. It is possible to do this with Canopy products in fields with low populations and no glyphosate resistance issues, but most fields benefit from use of residual herbicides in the spring, along with some additional burndown herbicide if needed. Most of the marestail/horseweed in Ohio is glyphosate-resistant, and many populations are resistant to ALS inhibitors. This requires much more intense thoughtful management than fields that don't have multiple resistance.

Grain Dust and Mold avoid asthma and farmers lung and wear a proper mask!

Del Voight
Got this from ISU in the email thought it was important enough to get onto my blog.  Read through this and hopefully you will be moved enough to take your own safety into mind as well as farm workers hauling grain and in all phases of the grain handling at the farm.  I know last season I followed a combine doing a harvest and sucked in who knows how much dust only to spend the next week feeling like a pneumonia case coughing constantly. I now keep a mask in the truck for this purpose.


Iowa Harvest Exposure to Mold and Dust in Grain   ISU
Grain dust is always a health concern for Iowa farmers and those working in the grain industry. Drought conditions this year may elevate human and animal health concerns because of increased dust and mold exposure. The Iowa Department of Public Health has issued 2012 Iowa Harvest Exposure to Mold and Dust in Grain, a fact sheet covering the following information.
The drought has created conditions favorable for an increase in dust and the production of aspergillus mold and associated aflatoxins. Exposure to low levels of grain dust during normal working conditions often causes reactions that are a nuisance, such as a cough, sore throat, nose and eye irritation, or feeling stuffed up or congested. People with chronic breathing problems or asthma may experience more symptoms or asthma attacks when exposed to high dust and mold levels.
Exposures to moldy and dusty grain, especially large exposures, may also cause two specific medical conditions with similar symptoms:
  1. Farmer’s Lung or Hypersensitivity Pneumonitis (FHP) – a fairly uncommon condition (one in 20 farmers) caused by a delayed allergic reaction to the dust. Repeated exposures can lead to permanent lung damage or limitations to work. A medical provider should be consulted.
  2. Organic Dust Toxic Syndrome (ODTS) – a more common toxic response to dust, molds, bacteria, or toxins in the grain dust. Recovery is usually in a few days, but a medical provider should be consulted.
Common symptoms include cough, headache, chest tightness, muscle aches, fever or generally not feeling well. If you have any of these symptoms, see your medical provider.

What you can do to protect yourself during harvest

  • Avoid direct exposures to dust whenever possible.
  • When working in extremely dusty conditions use a NIOSH-approved and certified “N-95” respirator that fits you properly. HOWEVER, consult your medical provider before using a respirator. Individuals with heart and lung conditions or other respiratory limitations should not use a respirator. N-95 respirators must be used only with a clean shaven face to ensure proper fit.
  • People with chronic respiratory health issues should avoid dust exposure.
  • If you have been exposed to large amounts of dust and you begin to feel ill, you should contact your medical provider for a proper medical evaluation.

Corn Silage Pricing ideas Dr. Greg Roth

Corn Silage Yield estimates with our spreadsheets (http://www.das.psu.edu/dairy-alliance/xls/pricingstandingcornforsilage-revised.xlsx ) this fall, we (Tim Beck, Virginia Ishler and I)  found that the price depends on where you are measuring it at.  At $7.00/bushel corn and a delivered price of $75.00, corn standing in the field was worth about $45/ton in one of our scenarios.  According to the NASS Custom Rates (http://www.nass.usda.gov/Statistics_by_State/Pennsylvania/Publications/Machinery_Custom_Rates/custom11.pdf) it costs about $9.60 a ton to chop haul and fill silo, so its worth about $55/ton in the silo, before its fermented.

These are close to the old rule of thumb estimates that corn silage is worth 8-10 times the value of shelled corn. I suspect the range is somewhat due to where you are measuring it.

Corn Silage and Disease Considerations

Del Voight- Penn State Extension
There are many questions as to the silage quality. Corn Kernels are germinating on the plant in some fields, various diseases are being observed on the ears as well as the stalks.  The decision will need to made on a case by case basis with inspection of  fields for which is the most prevalent disease and even then it will come down to a quality analysis and a mycotoxin screening. 

Forage Quality: Nutrient Composition

Page also has some factsheets on Mycotoxins, Nitrates, and other toxicity problems.
Is the dust safe?  Greg Roth related a recent article dealing with the dust. The bottom line is you will not know if the dust is safe to you or your workers so proceed as if it is not safe and use a respirator.  Flood corn silage polluted dust
"Can I chop and feed this stuff?"

In most cases "Yes" the grower can chop and feed this stuff. Soil on the plants will raise the issue of Clostridium growth and in a recent conversion with my veterinarian we vaccinated all my cattle with Ultrabac 8 that will prevent toxic affects from soil that might be on my fall pastures. He related that he is vaccinating all the dairy herds for this purpose of the likelyhood of soil being mixed into the forages.  Again testing forages is essential for mycotoxins.  There should be no feed toxicity issues with common rust and smut for corn silage. Mycotoxins can develop and are associated with temperature extremes. Due to the stresses encountered by the crop and the diseases expressed, quality as measured by milk per ton and milk per acre will likely be decreased.
Craig R. Grau  of Wisconin Extension had the following comment on a thread I read.  The key decision will be to ensile at the proper moisture for the storage structure to ensure adequate fermentation and preservation. That will likely be tricky due to the variabilty of the plants in the field.
Once the field is ensiled, a quality analysis should be done to see how badly quality was affected. A mycotoxin test should also be performed. Little research is available for multiple stress effects on silage quality. It may be correct and prudent that feeding should be limited to heifers, but a forage quality analysis will give the grower and nutritionist some confidence as to what kind of forage they are delaing with.
We had some reports of black dust on the silage could be smut due to the previous wind damage.  Paul Esker also from Wisconsin Extension wrote the following in another thread I read.... Smut galls are not poisonous to animals, but they will increase the dust content of dry matter. The acids in silage are typically enough to kill the spores. Interestingly, if the stalks, leaves, and ears are fed to animals, the smut spores can survive through the alimentary canal and be passed through into the manure. If this is spread onto fields, this can become a source of inoculum for infecting new corn plants. Also, smut is considered a delicacy in many parts of Central and South America. As for rust, the main concern would be if there is some decrease in palatability. Much of the work has examined the effect of southern rust (Puccinia polysora) and lower silage quality (mainly due to early plant death). If the forage is ensiled, the fermentation process would be expected to kill the fungus, thus reducing the concern of an unpalatable food source.

Early Planted Soybeans move into R3 Growth Stage

This season 2012 is extremely ahead of schedule and growers need to adjust accordingly.
Early Soybeans planted from Late March to Mid April have moved into the R3 Stage of growth and development. This is fully about a month ahead of normal.  For more staging information please visit my early blog on Staging Staging Soybeans.
We have found the most benefit from fungicide applications at this stage of growth.  Later applications tend not to protect yields as much as the earlier timing.  As growers scout fields a keen eye on insect pressure is critical for the inclusion of an insecticide to avoid running the soybeans down a second time. The relative small yield increase of 3-4 bu/acre demands attention to the overall economics.  Refer to my early blog article on sprayer width impacts on soybean yield. It just might pay to have a commercial applicator with wider boom width to apply the product saving yield from less beans run over. Soybean Yield Reduction from Boom width and wheel traffick.
As far as product selection there are many. Here are the numerous fungicides labeled for use in Soybeans.
