VDACS establishes quarantine for spotted lanternfly

Late Tuesday afternoon (5/28), Virginia Department of Agriculture and Consumer Services (VDACS) announced the establishment of a quarantine for spotted lanternfly (SLF), an invasive pest insect that was found in Winchester in January 2018 (ext.vt.edu/spotted-lanternfly).  This insect threatens to be a major pest of fruit crops, forest trees, and other plants in Virginia.  Despite an eradication effort in 2018, SLF increased its distribution from about 1 square mile to 16 square miles.  This year, the overwintering eggs began their hatch on April 27, earlier than last spring.  They are now in the second instar, or second nymphal stage.

The press release on the SLF quarantine linked here.  A direct link to the quarantine document is linked here as well.  The regulated area includes the City of Winchester and Frederick County.  Some of the key provisions of the quarantine are:

1) Regulated articles (plants, outdoor industrial materials, shipping containers, outdoor household articles, and others) may be moved from the quarantine area if they have been inspected, and are accompanied by a permit;

2) Regulated articles may be moved within the quarantine area following an inspection; a certificate is not required.

3) From April 1-Dec 31, regulated articles may be moved through the regulated are without stopping, or stopping only for fuel or traffic conditions.

4) To obtain a permit to move regulated articles, a person doing business must complete a VDACS-approved training (see below) and agree to train employees on identification of SLF.

The training needed to obtain a SLF permit is available online.  There is a $6.00 fee.
For questions on the quarantine and related issues:

For questions about the quarantine or movement of material or trucks, or the compliance agreement, call VDACS.  Call the Richmond number (804-786-5525) even if its a question about the Winchester area.

2019 Tree Fruit Schools

This year's orchard fruit schools will be held the week of Feb 11-15. Details are provided below:

2019 Revisions to Fruit Pest Management recommendations:

The revised Pest Management Guide for Home Fruit, Commercial Vineyards, Commercial Small Fruits, and Hops, are now available.  The tree fruit manual, separate from the Pest Management Guide series, is in production, and we hope to have it ready for our fruit schools.

The guides are available free online in PDF, and will also be available for purchase.

Spotted lanternfly a new invasive concern

A new invasive pest of small fruit crops and vineyards moved into eastern Pennsylvania in 2014, and has been spreading.  In 2017, the range increased from 6 to 13 Pennsylvania counties, and also into Delaware, New York and northern Virginia.  Specimens of dead adults and egg masses were found in January 2018 (actually 2017 individuals).  This pest poses an important risk for grape, orchard and tree crops. 
Click here for an Adobe Presenter talk on this species.  A fact sheet is available from Virginia Tech (a USDA fact sheet is available in Spanish).  In addition, there is a Virginia Tech Pest Alert, with additional information on recognition and reporting (this is also available in Spanish).  Now that spotted lanternfly has been found in Virginia, it will be important to follow its spread through the state.  To report a suspected find, please follow this linkhttps://ext.vt.edu/spotted-lanternfly.

Brown marmorated stink bug and Virginia fruit:

See StopBMSB.org web site!  A new addition to the stink bug complex is brown marmorated stink bug, Halyomorpha halys (Stål).  Brown marmorated stink bug (BMSB) has recently been introduced from Asia into the northeastern U.S.  It was first detected in 1998 in Allentown, Pennsylvania (see NAPIS map; this map underrepresents the situation in Virginia).  It was later found in New Jersey, Maryland and Delaware, and in October 2004 it was found in Montgomery County, Virginia, and in Tennessee in 2008.  Injury in tree fruits can be severe, exceeding 25% (individual blocks have been estimated to have much higher levels of fruit injury).  Externally, fruit may have multiple reddish dents at feeding sites, resembling hail strikes.  Upon cutting into fruit, corky areas are seen in the flesh of the fruit.  In vineyards, a unique problem is posed.  Stink bugs may be harvested along with clusters and be transported to the winery in lugs or bins, where the wine can be imparted with a "stink bug taint".  Research is underway to test short-residual insecticides to knock down BMSB from clusters at harvest.  For further information and images, see the Brown marmorated stink bug page.  A working group on organic management of BMSB has been established, with their own web site.  There is opportunity to participate in grower forums.

New!  The College of Agriculture and Life Science at Virginia Tech has established a new on-line Master's in Agriculture and Life Sciences.   This curriculum has been approved by the State Council of Higher Education and is now accepting applications for Fall semester 2007.  In this program, you can earn a master's degree in agriculture while working in your current job - emphasis is on education for place-bound learners, and all courses are taken on-line.  In addition to a core area, there are courses offered in five areas of concentration: (1) Biosecurity, Bioregulations and Public Health, (2) Education, (3) Environmental Science, (4) Food Safety, and (5) Plant Science and Pest Management.  In addition to course work, the student completes a project decided upon in consultation with your major advisor.  Lists of courses within each concentration may be found in the web site linked above.  This program was recently the subject of an interview by Jeff Ishee with Virginia Public Televsion's Virginia Farming.  For more information, contact Doug Pfeiffer (dgpfeiff at vt.edu) or Sharon Proffitt (sproffit at vt.edu) (see 2008-2009 Extended Campus tuition rates).

Mating disruption and Organic certification:
The National Organic Standards Board has recently amended organic guidelines so that many pheromone dispensers for mating disruption will now be allowed in organically certified orchards.  Most hand-placed dispensers are now considered to emit negligible amounts of inerts, and will be allowed.  Sprayables and puffers will not be allowed.  More information will be posted when available.


Apple Maggot and Exports to Brazil:

A protocol to manage apple maggot that will allow Virginia growers to export apples to Brazil was recently approved. As modified from earlier versions, it seems to be a usable protocol. Several options are available, at the grower's discretion. One involves the use of regional trapping. This approach uses traps in an apple region; sprays in the whole region start when the first fly is captured. The second approach uses site-specific trapping (traps at a specific orchard). Both of these approaches call for traps to be in place before first fly activity. The third option uses degree day accumulation. If growers can provide daily max and min temperatures, the expected fly emergence can be determined, and correlated with spray records. First adult emergence is expected 900 degree-days above 50 F.
