Rabbit Owners. Protect Wild Rabbits from Emerging Rabbit Disease

Pennsylvania has detected a case of Rabbit Hemorrhagic Disease Virus (RHDV) case in domestic rabbits in Western Pa. This follows on the heels of a New Jersey detection in March of 2022. RHDV has been evolving and spreading in pet rabbits since cases were first detected in North America in 2000.

Because this is an emerging disease, it is possible we can limit widespread infection in domestic and wild rabbits by practicing biosecurity measures at home and not releasing or disposing of domestic rabbits into the wild.

Example Timeline of RHDV1 Strain Detections in North America | and evolution into RHDV2 Strain

  • 2000 (Iowa)
  • 2001 (Utah, Illinois, New York)
  • 2005 (Indiana)
  • 2008 (Maryland)
  • 2010 (Minnesota)
  • 2016 (Quebec, Canada) detection of the more contagious RHDV2 strain*
  • 2018 (Ohio) detection of the more contagious RHDV2 strain*
  • 2018 (Pennsylvania)
  • 2019 (Vancouver, Canada) detection of a different strain of the contagious RHDV2 strain*
  • 2019 (Washington) detection of the more contagious RHDV2 strain*
  • USDA APHIS notice on 2019 outbreak link is here
  • In recent Canadian outbreaks of RHDV2, the death rate was close to 90%.
  • 2020 Outbreak of (RHDV2) associated disease occurred in the southwestern United States following its first detection in New Mexico in March
  • 2020 (New York City, 13 cases linked to a veterinary hospital) RHDV2 strains*
  • 2022 (New Mexico, Arizona, Texas, Colorado, California, Nevada, Utah, Idaho, Wyoming, Montana, and Oregon)
  • 2022 (New Jersey)

* This new strain is able to infect a wider variety of rabbit species including wild rabbits.

If you notice these symptoms in rabbits, isolate them and contact your veterinarian and your state’s Division of Animal Health. If you see dead wild rabbits that lack explanation, contact your state Game and Wildlife Division:

  • Rabbits die suddenly without symptoms
  • Rabbits have a fever
  • Rabbits are uncoordinated, excessively excited, have convulsions, paddling, or paralysis
  • Rabbits have difficulty breathing just before death
  • Rabbits have bloody discharge from nose or stools
  • Rabbits have eye hemorraghes

To protect the wild rabbit population, do not release domestic rabbits into the wild and do not dispose of dead rabbits in the wild.

For more information about measures in New Jersey see the state press release: https://www.nj.gov/agriculture/news/press/2022/approved/press220513.html

If you are traveling between or through states, be aware of the interstate-intrastate quarantine regarding domestic rabbit movements in Pennsylvania. The PA “Interstate and International Order of Quarantine is applicable to all States, Commonwealths and territories of the United States of America and any foreign country in which the dangerous transmissible disease RHD exists or there is a reasonable suspicion it exists.”

New Jersey residence who suspect RHDV2, should alert the NJDA, Division of Animal Health at 609-671-6400. The 24-hour number to report a foreign animal disease to USDA APHIS VS Area Veterinarian in Charge is 866-536-7593.

Accelerated Irrigation Funding Now Available for New Jersey Producers

SOMERSET, N.J., Sept. 1, 2022 – The USDA’s Natural Resources Conservation Service (NRCS) in New Jersey is now accepting applications for accelerated Environmental Quality Incentives Program (EQIP) ACT NOW funding for irrigation.

Through this unique opportunity, producers and landowners can convert their existing overhead systems to low flow, high-efficiency systems such as drip or pivot which will efficiently and uniformly apply irrigation water, maintain soil moisture for plant growth, prevent contamination of ground and surface water, and improve poor plant productivity and health. Irrigation may also be combined with soil health practices to improve soil quality.

While NRCS accepts applications year-round, NRCS-NJ has established an evaluation period cut-off date for ACT NOW Irrigation funding of October 1, 2022. Applications submitted prior to the cut-off will be assessed and ranked as soon as the applicant has made treatment decisions through a conservation plan. Land offered for enrollment in EQIP must have been irrigated for at least two out of the last five years to qualify for irrigation-related conservation practices.

Based on fund availability, application assessments with a ranking score of 70 points or greater will be preapproved immediately, allowing the applicant to ACT NOW and achieve contract approval to begin practice installation without being evaluated against other submitted assessments. Application assessment ranking scores less than 70 points will be batched and funded in ranking order as funding allows.

For more details on EQIP, please contract your local USDA Service Center or visit https://www.nj.nrcs.usda.gov

Back-yard Poultry Producer Alert: HiPath Avian Influenza deaths in wild birds

On August 8th, 2022, The United States 2022 Detections of Highly Pathogenic Avian Influenza in Wild Birds reported multiple confirmations of dead black vultures in Sussex County, NJ. Today, August 29, 2022, the media has released information that a hundred dead vultures were found in the vicinity of the Sussex Branch Trail in Lafayette, NJ.

Back-yard producers in Sussex County should review their biosecurity measures to prevent avian influenza from wild birds coming in contact with their flocks.

For more information and who to contact in the NJ Department of Agriculture if you have a death in your poultry flock, see the following post https://plant-pest-advisory.rutgers.edu/poultry-alert-review-implement-biosecurity-measures/

Non-herbicide Management Options for Large Crabgrass in Specialty Crops

Large crabgrass can form robust root systems thanks to its numerous tillers and capacity to root at stem nodes, allowing it to out-compete crops for moisture and nutrients.  Understanding the life cycle and biology of large crabgrass is key to figuring out the best options for its control on your farm. Learn more about non-herbicide life cycle disruptions that can be used in the development of a short and long term management plan through the large crabgrass decision tool fact sheet and an informational video. These resources are one of a five-part weed management series created by Extension Specialist Thierry Besancon and County Agricultural Agent Meredith Melendez, funded by USDA Specialty Crop Block Grant AM190100Crabgrass. Provide feedback on these resources through an online survey.

Apples and Pears:

Brown Marmorated Stink Bugs: Brown Marmorated Stink bugs are present at low to moderate levels in orchards statewide, However Activity is incresing form both Native and Invasive species. BMSB nymphs have also been seen in some orchards. See the NJ Tree Fruit Production guide for effective materials. In addition to the apple materials listed in the guide, Venerate has a +++ rating for stink bugs and a 0 day PHI.

Codling Moth (CM): Timings for the second generation are updated below.  A biofix was set for CM on April 25th in southern counties, and May 6 in Northern counties (Middlesex County). Second generation treatments according to the degree day model are now over. Additional treatments should be made if trap captures are over 5 moths/trap. Some orchards have had continuing trap captures above threshold.

Lesser Appleworm: Some orchards in southern counties have had internal worm damage that we think is Lesser Apple Worm. This sporadic pest sometimes shows up in late summer and fall. The damage is similar to codling moth. Larvae complete their life cycle quickly and often by the time damage is seen the larvae is already gone. Typically LAW will feed in the fruit calyx and not go into the flesh, however they may also feed on fruit flesh excavating a small hole under the skin and occasionally tunneling into the fruit. Control options are the same as for codling moth.

Grape

Bunch Rots: Disease management continues to focus on downy and powdery mildew and also turns to bunch rot management. Refer to the NJ Commercial Grape Production Guide as well as the linked presentation from Dr. Nita in Virginia. Additional information can be found in this linked presentation from Dr. Bryan Hed at Penn Sate.

Grape Berry Moth: The timing for the third generation is past. In some hot summers a fourth generation may occur, however no further treatments should be needed, especially where insecticides are being applied for SLF and SWD.

Drosophilds and Sour Rot: SWD adults are being caught in and around commercial vineyards. As the sugars start to increase in early verities like Chardonnay, be aware of Spotted Wing Drosophila combined with native fruit fly species. These populations increase at this time of year and help spread sour rot. Sour rot will only be present when you also have injured fruit. Fruit splits and various insects can help cause that initial injury. It is thought that the spotted wing drosophila (SWD), because of its saw-like ovipositor, can help cause this initial injury, helping to make the fruit more attractive to native drosophilid species.  After injury the fruit serves as a food source for ethanol-producing yeasts and acetic acid producing bacteria, the causal agents of sour rot. This in turn attracts more fruit flies to lay more eggs and spread the decay. Good canopy management for air circulation is useful to reduce sour rot incidence. However, this must be combined with insecticides and antimicrobials. A treatment regime that consists of weekly applications of an insecticide (Mustang Maxx (or other pyrethroid), Malathion, Delegate/Entrust, Verdepryn).  Add Oxidate 2.0 if fruit cracking from rain or other causes is observed. Since it is important to rotate insecticide classes when treating this often, growers should use no pyrethroid or other insecticide class more that 2 times in a row. These treatments should be started before the onset of visible sour rot and fruit fly presence.

Spotted Lantern Fly: Spotted lantern fly adults are now appearing in vineyards. At this stage border treatments with effective materials should be adequate since most adults will be found on vineyard edges and populations will be low. As we move into September adult migration will increase and at that point growers should apply materials with long residual efficacy (refer to the table from Penn Sate below. *Chlorpyrifos is no longer labeled for food use.) More information on biology and control can be found from Penn State.
