REMINDER: Upcoming Sales Closing Dates

RMA wants to remind producers about upcoming Sales Closing Dates for crop insurance coverage.  Sales closing dates vary by crop, state, and county, but in Vermont, most spring-planted crops have a sales closing date of March 15, 2018. The deadline for growers of nursery crops is May 1.

Federal crop insurance is critical to the farm safety net. It helps to mitigate the inherent risks farmers and ranchers face, from natural disasters to market related challenges. In order for producers to obtain coverage, they must to apply for coverage by the Sales Closing Date for the production year. Producers should contact their crop insurance agent soon to discuss dates and new options available.

Crops Stressed by Rains

Posted: July 7th, 2017 by outcropn

With last week’s deluge of rain in many parts of the state and this weekend’s forecast, we have dug up a couple of past blog posts that may be of interest:

Recent Rain Creates Stress on Crops addresses flooding, ponding, and soil saturation of corn, pasture and and hay fields.

Rain Putting a Damper on Your Forages? Options Available provides information on late season forage plantings.

It’s been a challenging growing season thus far but there’s still time to produce high quality, high producing forages.

Rain Putting a Damper on Your Forages? Options Available

Posted: June 28th, 2017 by outcropn

Cow munching on Japanese millet.

Rain, rain, go away, we haven’t been able to harvest our hay…or plant our forages! If you’ve been singing this song, you are not alone. With this wet weather, farmers across the region have seen poor corn germination, challenging hay harvest windows, and field conditions making planting difficult.

While it has been tough going so far, the best part of the growing season is yet to come. There is still time to produce high quality and yielding forages this season! Your options include short season corn; warm season annual grasses like millet, sorghum, sudangrass, etc.; small grains like oats, triticale, etc.; and perennial hay and pasture — all have the potential to produce high quality forage for the winter months.

Our fact sheet on late season forage plantings describes some of the options available.

If you’re thinking about summer annuals, Heather and University of Maine Cooperative Extension’s Rick Kersbergen discussed strategies for planting, harvesting, and feeding these forages during an eOrganic webinar.

In addition, our livestock forages page contains factsheets and research reports on short season corn performance trials, summer annuals, and more!

Armyworm Alert

Armyworms were spotted in Addison County Vermont on June 12, 2017. Please don’t panic but do scout your corn and grass fields for armyworm caterpillars.

True Armyworm, Pseudaletia unipuncta, are typically spotted each year on some acreage in Vermont — crops most affected are grasses including field corn, grass hay and pasture crops. It is important for farmers and consultants to monitor fields. At high populations, armyworms can create significant damage very quickly.

Scout for caterpillars. When mature, they can be almost 1.5 inches long. The caterpillars are usually greenish or brownish, but can be almost black. The sides and back of the caterpillar have light colored stripes running along the body. They normally feed at night and can cause much damage before they mature.

Their preferred foods are grasses including corn, grains, and timothy but they will feed on other plants if grasses are unavailable. Feeding will start on the lower leaves and move upwards. A large population of armyworm caterpillars can strip an entire field in just a few days. When the field is eaten they “march” to adjacent fields. Please note: Corn fields that are reduced or no-tilled or fields infested with grass weeds are most susceptible.

For more information on armyworm, see “When Armyworms Come to Town” and/or True Armyworm resources on the Vermont Crops & Soils webpages. For additional scouting and control options, please contact the following agronomists.

Grain Growers Take Note of Powdery Mildew Alert

Posted: June 13th, 2017 by outcropn

The cool wet weather throughout the spring has created the ideal growing conditions for a plethora of fungal pathogens. Several leaf diseases have been observed in our grain trials this season. One of the more easily identifiable ones is powdery mildew.

Powdery mildew is a common disease of grain crops and can be observed periodically on virtually any crop. Different fungi cause powdery mildew in different crops but all of the powdery mildew fungi are closely related. In grain crops, the causal fungi are mainly in the genus Erysiphe.

Powdery mildew first appears on the surface of the lower leaves as white powdery patches. If the conditions remain ideal for powdery mildew development, these patches will get larger, run together, and eventually cover large portions of the leaf. The white, powdery growth turns a dark yellow-gray with age. Many dark specks resembling grains of pepper (powdery mildew fruiting bodies) form in these patches later in the summer. Yellow, necrotic lesions will appear on the lower leaf surface directly beneath the patchy areas of the mildew. Under the right conditions, the powdery mildew will move from the lower leaves to the upper leaves and occasionally will spread to the grain head.

Severe infection of powdery mildew can reduce yields by disrupting a host plant’s photosynthesis, respiration, and transpiration. Plants lose vigor and as a result, there is a reduction in grain fill.

If you have questions about powdery mildew or any other plant disease, the University of Vermont Plant Diagnostic Clinic can help. Click on the following link for details on submitting a sample for identification: http://pss.uvm.edu/pd/pdc/pdf/pdcform.pdf.

Performance of Winter Canola Varieties

Posted: March 13th, 2017 by outcropn

Canola, a member of the mustard family, is primarily grown as an oilseed crop across the Midwestern U.S. and Western Canada. The crop is of interest in our region for providing fuel, feed for livestock, and providing more rotational crop options.

There are spring canola varieties–planted in the spring and harvested in the summer–and winter canola varieties planted in late summer which lie dormant over the winter and are harvested in mid-summer the following year. Winter canola, therefore, has the potential to fit into field rotations with other annual crops such as small grains or annual forages. However, in the Northeast, the challenge with growing winter canola is winter hardiness. Because our region often experiences harsh and volatile winters, these conditions can lead to widespread winterkill.

Seed yields of the 15 different varieties of winter canola we researched. Click on image to enlarge.

To investigate the potential of winter canola performance in our region, we compared 15 different varieties, evaluating yield, oil content, and other parameters. Due to extremely mild conditions during winter 2015-16, all of the canola survived and was harvested.  The highest yielding variety was Mercedes which produced over 2300 lbs. ac-1. Eight of the other varieties performed statistically similar to Mercedes, producing between 1878 and 2169 lbs. ac-1. The droughty conditions experienced throughout last season did not seem to impact canola yields; they averaged over 1800 lbs. ac-1 and test weights averaged 49.5 lbs. bu-1 which is on par with the industry standard test weight of 50 lbs. bu-1. These data suggest that winter canola, when it overwinters in this region, has the potential to provide significant yields and opportunities for crop diversification.

Gearing Up for Spring: Improve Your Pasture & Hayland through Frost Seeding

Posted: February 23rd, 2017 by outcropn

With the spring-like weather these past few days, now’s the time to consider frost seeding as a cost-effective method to improve forage diversity and quality in your hayland and pastures.

Frost seeding is a low cost seeding strategy that relies on the action of the soil freezing and thawing to achieve the seed-to-soil contact needed for germination. Frost seeding may begin when fields are without snow cover but when the ground is still frozen.

Some keys to successful frost seeding include:

  • Removal of extra vegetation before seeding (ideally grazing or mowing in the fall),
  • Seeding early in the spring (after the snow is gone but while the ground is still frozen),
  • Selecting species that can germinate when cold–Ideal species for frost-seeding include red and white clover seeding at rates between 6 and 8 pounds per acre–and,
  • Allowing for new seedlings to establish (avoid over grazing and letting plants grow to 6 to 8 inches before harvesting).

For more information on frost seeding, visit our article, “Frost Seeding: A Cheap Alternative to Improve Hay and Pasture Land.”
