2019 Virginia Ag Expo Comes to Charity Hill Farms in Caroline County

Posted on by

The Virginia Ag Expo is the largest agricultural field day held in the Commonwealth of Virginia. As an educational, marketing and social event, farmers and agribusiness look forward to the Virginia Ag Expo each year. This year’s event will be held at Charity Hill Farm in Ruther Glen, VA on August 1st.

Charity Hill Farm is an 800-acre farm owned and operated by The Smith Family in Caroline County.  Its active members are Steve and Cindy Smith and their son Chris. The farm has been in the Smith family for six generations and is a certified Virginia Century Farm.  Originally known as Smith Dairy Farm, the dairy cows were sold in 2006, and the operation began its transition to beef cattle with the help of the Smith’s daughter, Kendal, who is now a large animal veterinarian in Nebraska.  Over the last 8 years, the Smiths have focused on growing and perfecting their 200 head beef herd, and Chris began retailing their BQA Certified, USDA inspected beef directly to the consumer in 2017.  The Smiths additionally farm 1,200 acres of grain crops in Caroline and Spotsylvania counties, 150 acres of hay and 55 acres of managed timber. Agritourism events are also hosted at Charity Hill, and they work to promote conservation initiatives. The Smiths are proud to have won the 2010 Hanover/Caroline Soil and Water Conservation District and York River Basin Clean Water Farm Awards.

Breakfast and lunch will be provided at the Ag Expo by Virginia food vendors.  Attendees will be able to eat any time from 7:30 AM to 2:00 PM.

Over 150 exhibitors and sponsors will have on display all of the most up to date equipment, goods and services for agricultural producers and property owners no matter how large or small.  Field tours will also be presented by many of Virginia’s top agricultural researchers, Extension Agents, and NRCS personnel.

The Virginia Ag Expo is sponsored by the Virginia Grains Producers Association and the Virginia Soybean Association, in cooperation with the Virginia Cooperative Extension Service.

Location: Charity Hill Farm, 9482 Golansville Rd, Ruther Glen, VA 22546

 

Aphids in alfalfa

Posted on by

Large aphids populations have been observed in alfalfa this year following insecticide applications targeting alfalfa weevil. If you haven’t scouted for alfalfa weevil in Virginia, you should. See the bottom of this post for a weevil summary.

Aphids, typically pea aphids, can be problematic when their natural enemies are disturbed. They can reduce vigor and cause wilting in first cuttings. If early cutting is not an option, several insecticides (mostly pyrethroids) are labeled for their control. Low label rates are generally effective as long as you ensure good coverage. Scout for aphids by pulling 30 random stems per field and counting the number of aphids. This guide from Iowa State can help you make treatment decisions.

Most of the aphids I have seen in Virginia alfalfa are pea aphids (left) and cowpea (right). If you think you have another species, please give me a call or send an email.

Alfalfa weevil information

Scout fields by pulling 30 random stems and inspecting foliage for weevils. Weevil larvae are small, can be white, yellow, or green, and have black heads. They are often tucked tight into new growth. It’s possible to dislodge larger larvae so be careful or collect stems into some container that catches these. I use a plastic freezer bag and insect stems in the shop or truck. This guide from Penn State can help you make spray decisions. Cutting alfalfa is an option if you don’t want to use pesticides. I recommend using clorpyrifos based on spray tests in 2018 and 2019. Some people have been successful with indoxacarb (Steward) or pyrethroids (many brand-name and generic options). Coverage is essential with any product.

 

armyworm in VA small grains

I have received several reports from Virginia Beach and Chesapeake of armyworms infesting wheat and hay in large numbers. Neighboring regions of NC are experiencing similar outbreaks.

Overall, these infestations are rare in our state, but scouting is recommended. Fields treated previously with pyrethroids may be at higher risk because they contain fewer natural enemies to combat pest outbreaks. Armyworms feed at night and may be found under residue and at the base of plants during the day. Oftentimes, they can be seen curled into a c-shape (see photos below). Thresholds are one larvae (0.75 in or longer) per linear foot in barley and 2-3 per foot in wheat. Refer to Chapter 4 of Virginia Tech’s “Pest Management guide: Field Crops” for products and rates labeled for armyworm control in our state. Pay attention to PHI before making an application. Pyrethroids can be effective against armyworm. Good coverage is critical, especially in high residue fields.

Eastern Shore AREC Field Day CANCELED!

Posted on by

Due to impending rain Tuesday and Wednesday and already saturated soils, the Eastern Shore AREC field day scheduled for Wednesday, September 13, 2017 has been canceled. Let’s hope Hurricane Irma keeps tracking further west. We certainly do not need any more rain!

Second DD update for billbugs in orchardgrass

Posted on by

The number of accumulated degree-days (DD) for bluegrass and hunting billbugs in orchardgrass since 1/1/11 are starting to move. As of 4/6/11, 214 DD have accumulated. Model forecast for 4/13/11 is 284 DD. Recall that at least 280 DD are needed before taking any action. Within the next week or so you need to start checking your field borders for paired-field holes. My contact information is, 540-231-9118 (office), 540-357-2558 (cell), youngman@vt.edu. Thank you.

Orchardgrass: First update on billbug degree-days

Posted on by

Greetings
According to the Agmaster degree-day collection service – same
company we’ve been using. Given a Jan. 1, 2011 start date, and as of
Mar. 23, 172 DD have accumulated. Model predictions for April 2, are
195 DD.

Recall, 280 DD represents the start of billbug adult activity moving
back into orchardgrass. At this point and beyond you need to start
monitoring field edges for the paired-feeding holes that adults make.
This is a presence/absence sample that gives you an idea on whether
or not they’re in a field. There are no thresholds for spraying or
not spraying – personal judgement call.

As always, if you need more information, contact your local extension
agent or me. My office number is 540-231-9118, cell 540-357-2558, email youngman@vt.edu
