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.
