Hill-Up your Grapevines to Prevent Winter Injury

Freeze injury on grape flower buds and canes can cause crop loss and increased disease problems, but freeze damage at the graft union can kill the entire vine! The most effective technique for limiting freeze injury to the graft union is hilling up soil around the vines high enough to cover the graft union with 3 to 4 inches of soil. This practice is especially important for vines less than 5 years old. Now, before temperatures drop and the ground freezes is the time to get out there and hill up your vines. Factsheet 1264 https://njaes.rutgers.edu/fs1264/ details the following important aspects of hilling-up to protect the graft union from cold damage.

  • Dead grapevinesThe principle of Hilling-up – How the soil works, both as a thermal mass that holds the heat and an insulator that slows heat loss.
  • How to perform effective hilling-up using available and specialized implements.
  • Cost benefits of using the implements.
  • Challenges such as timing, preventing damage to the drip lines and trunks during hilling-up; and how to address those challenges.
  • The process of hilling down in the spring to prevent root formation above the graft union and proper weed management.

SARE Farmer Grants for 2023 – Webinar on October 4th

Truck spreading fertilizerMultiple Northeast SARE (Sustainable Agriculture Research and Education) grant recipient Tommye Lou Rafes, of T.L. Fruits and Vegetables in West Virginia, is sharing her experiences to help other farmers experiment with new ideas through the Farmer Grant program.

At noon on October 4th, 2022, Rafes will join Northeast SARE Grant Coordinator Candice Huber for an informational webinar to assist farmers interested in applying for up to $30,000 in funding for projects beginning in March 2023. Registration is required and participants are encouraged to submit questions ahead of the event. The Call for Farmer Grant Proposals is currently available and the online system for submitting applications is opening soon. Applications are due November 15, 2022.

Northeast SARE Farmer Grants are perfect for farmers looking to grow through new practices. Rafes first learned about SARE while attending a Good Agricultural Practices (GAP) training. One of the professors hosting the meeting was a SARE reviewer who invited the attendees to apply for a grant. Rafes knew sustainable practices like using renewable-powered high tunnels to extend growing seasons could be good for business as well as the planet. “Growing in the winter months is a completely different way than you do in the summer months,” she said. “I decided to test varieties that were successful during the winter months as well as growing conditions that could be improved so that people would be more successful.”

Grant Coordinator Candice Huber says Farmer Grants are an opportunity for farmers to try things that could improve their operations. SARE funds can cover the farmer’s time on the project, any farm workers time spent on the project, supplies that are not capital purchase, technical support, soil testing and other budgeted items. Farmer grant projects generally are for one year.

If you have an idea and you need resources to really explore it, a Farmer Grant can connect you with those resources. This webinar will be a good starting point and participants must pre-register. See below.

To sign up for the October 4th webinar at 12:00PM go to https://us02web.zoom.us/webinar/register/6516611235851/WN_RoG_IkMmSDGsduZwmFgKkA

SLF: 2022 Management Recommendations in Vineyards

by Katarzyna Madalinska and Anne L. Nielsen

Adult SLF are moving into vineyards from the surrounding landscape. The number of SLF on each vine varies greatly within each vineyard and locations in the state. In most vineyards in NJ and PA there is a strong border effect with numbers highest along the outside rows. However, the orientation and shape of your vineyard influences border effects. SLF are actively feeding on grapevines and will continue to feed for 1-2 months. Most SLF are in the upper canopy and as the grapes start to store carbohydrates for the winter, SLF will move down the vine, eventually feeding at the base of the vine. Research suggests that feeding by adult SLF may harm primary bud formation the following season and reduce winter hardiness. There is not a specific treatment threshold, but a good rule of thumb is 10 SLF per vine. Movement into the vineyards will continue for several weeks so multiple insecticide applications may be needed.

Treatment at this time of year is of course complicated by pre-harvest intervals (PHI) for each insecticide and grape variety. It is important to remember that SLF will feed on vines post-harvest. There are several effective insecticides available with pre-harvest intervals and residual activity (Table 1). When treating vines pre-harvest, dead SLF are commonly observed in the clusters. Post-harvest, insecticides such as Danitol or Brigade/Bifenture/bifenthrin have the longest residual activity and are expected to reduce feeding.

There are several reasons to manage adult SLF in September and October during peak movement.

  1. Adults feed on the canes, cordon, and trunk of grape vines. Excessive feeding has been shown to lower winter hardiness by >1.5°C.
  2. SLF females lay egg masses in October. Killing females prior to egg laying will decrease population growth the following year.

Notes from the 2021 Chardonnay Wine Tasting and Evaluations Workshop

A Chardonnay wine tasting and evaluation workshop for winemakers was held on August 18, 2021, at the William Heritage Winery, located in Gloucester County. Chardonnay is one of the most suitable Vitis vinifera varieties for New Jersey for both north and south New Jersey. It is also one of the best white varieties for New Jersey in terms of consistency in ripening. It can be easily adapted in the winery for Sparkling, dry still varietals, and white wine blends. For example, a few wineries blended 75-80% Chardonnay with the remaining comprised of Pinot Noir, Pinot Gris, and Sauvignon Blanc. The responses to a survey weeks before the event formed the basis of discussion at the workshop. Winemakers also described how they accomplished each of their wines. [Read more…]
