A Cabernet Franc Wine Tasting Workshop was held on Nov 25th, 2019 at the Unionville Winery located at Ringoes in Northern New Jersey. The purpose of the meeting was to taste and evaluate Cabernet Franc wines released from NJ. A survey was sent out to the industry to report clones, harvest, and fermentation parameters. The survey respondents also formed the basis for the discussion at the workshop. [Read more…]

Cranberry Update: EPA Bans Use of Chlorpyrifos (Lorsban) On Food Crops
After years of debate, the U.S. Environmental Protection Agency announced on August 18, 2021 that this year will be the last that the insecticide chlorpyrifos (the active ingredient in Lorsban) will be allowed for use on food crops, including cranberries. This means that use of chlorpyrifos will no longer be allowed on cranberries in 2022 and thereafter. For more information, please see the press release here: https://www.epa.gov/newsreleases/epa-takes-action-address-risk-chlorpyrifos-and-protect-childrens-health.
In New Jersey, cranberry growers have mainly used chlorpyrifos early in the season to manage blunt-nosed leafhoppers as well as other insect pests such as Sparganothis fruitworm, blackheaded fireworm, and spotted fireworm. Growers can find alternative insecticide options for managing these pests in the Commercial Cranberry Pest Control Recommendations for New Jersey https://njaes.rutgers.edu/pubs/publication.php?pid=E308.

Monitoring for the Cranberry Toad Bug
As we approach the end of July, growers need to start monitoring for the cranberry toad bug, Phylloscelis rubra (Figure 1). In a recent study,
Figure 1. Cranberry toad bug.
we showed that even relatively low densities of this insect can cause significant injury to cranberries (Rodriguez-Saona et al. 2020. Characterizing the Feeding Injury Caused by Phylloscelis rubra (Hemiptera: Dictyopharidae) to Cranberries, Journal of Insect Science, 20 (6), 37, https://doi.org/10.1093/jisesa/ieaa143). Thus, monitoring for this insect from the end of July through mid-August is critical.
Life cycle. Cranberry toad bugs feed only on cranberries. This insect has a single generation per year. It overwinters as eggs. The nymphs appear by the end of June through early September, and the adults from end of July through October (harvest) (Figure 2). Eggs are laid from end of August through October.
Damage. Feeding damage can be noticed in two stages. 1st-stage feeding damage on vines causes closing in (towards the branch) of the leaves on the new growth. 2nd-stage feeding causes changed in color (reddish to brown) of new growth. The damage can be seen from July until harvest. This damage will cause dying of the branch and the berries to shrivel up (Figure 3). Heavy infestation will result in dwarfed

berries.
Management. To determine infestation, lightly sweep problematic beds (bugs should be easy to catch in sweep nets as they are very active). Currently there is no threshold established for this pest. Thus, insecticide applications should be based on the relative number of bugs per sweep compared with other sites and previous history of infestation. If needed, growers can use the following control options: Sevin 4F (broad-spectrum carbamate), Diazinon, Imidan 70W (broad-spectrum organophosphates), Actara or Assail 30SG (neonicotinoid insecticides, effective against piercing-sucking insects). If infestation is high, treatments should be applied in early August for best control.
