Spotted lanternfly a new invasive concernA 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.

Proposed pollinator protection plan

Honey bees have been at greater risk in recent years because of Colony Collapse Disorder, which results from a combination of stress factors.  In order to address this, the Virginia Department of Agriculture and Consumer Services has created a draft plan to protect pollinators from pesticides has been developed.  In preparation for a June meeting in Richmond, grower, extension agent and beekeeper feedback is requested.  The draft plan is linked here.  A web application is mentioned in the text; this DriftWatch site is available here.  Please send your thoughts on this proposed program to Doug Pfeiffer (dgpfeiff at vt.edu) by June 12.  Any comments are appreciated!

Spotted wing drosophila:  A new invasive pest of small fruit crops and vineyards moved through Virginia in late summer 2011.  Spotted wing drosophila, Drosophila suzukii, differs from other species of vinegar or pomace flies in that it lays eggs in ripening fruit on the vine or plant, rather than in overripe or rotting fruit material.  This has the potential to be a major problem for growers of soft-fruited crops.  More information is posted in a SWD page in the Virginia Fruit web site.  Hear an Adobe Presenter presentation on spotted wing drosophila in vineyard and berry crops.  In May 2013, 24(c) labels were approved for malathion 8F for blueberries and caneberries grown in Virginia.  Blueberry: Allowing up to 2.5 pts/acre for spotted wing drosophila.  Maximum number of applications is 2, with a minimum of 5 days between applications.  Do not exceed a total maximum from all sources of malathion of 5 lb ai/acre/year.  Do not apply within 1 day of harvest.  Caneberries Allowing an additional application for spotted wing drosophila.  The maximum application rate is 2.0 pts/acre; the maximum number of applications per year is 4, and the minimum retreatment interval is 7 days.  Do not exceed a total maximum use rate of all sources of malathion of 8 lb ai/acre/year.  Do not apply within 1 day of harvest.

New insecticide mode of action for spotted wing drosophila: A new insecticide has been approved by EPA, and received a state label in Virginia on 14, 2014.  Exirel has the common name cyantraniliprole, also known as cyazypyr.  This product is approved for bushberries, including blueberries, and stone fruits, including sweet and sour cherries.   The use rate for this pest on each of these crops is 13.5-20.5 fl oz per acre, with a 3 d PHI.  It is not approved for caneberries or grape.

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.  Listen to Adobe Presenter presentation on BMSB in vineyards and caneberries (14 min.).

Horticultural Topics:
Shift-trellises for Brambles:
The late Dr. Herb Stiles published two experiment station bulletins on trellising systems for brambles (Va. Agric. Exp. Stn Bull. 95-2 and 99-1). Abstracts are available here for publications on Shift trellis and Limited Arm Rotation Shift Trellis systems. For the entire publications, go the the Horticultural Topic sections.

Miscellaneous Topics:

New name for NABGA:  The North American Bramble Growers has changed its name!  It is now the North American Raspberry and Blackberry Association, NARBA.  There is new contact information as well.  The new e-mail is info@raspberryblackberry.com, and the new phone is 919-542-4037.

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).

Virginia Berry Conference:  The 6th Annual Virginia Berry Production and Marketing Conference was held on the Virginia State University campus on March 14, 2013.  See the program linked archived here.
