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…]

Webinar on Spotted-Wing Drosophila Monitoring and Sampling
Registration is now open for our annual Sustainable SWD Management webinar, scheduled for Nov 10th at 1pm ET. Register here: https://ncsu.zoom.us/webinar/register/WN_JhupsLFhSKi_f8z4mzl56g
This year’s webinar is entitled: Monitoring and sampling tools to improve spotted-wing drosophila management. This 1hr session will share current recommendations for adult and immature SWD sampling methods and practical applications of these tools for fruit growers. Presenters include: Rufus Isaacs & Steve Van Timmeren (Michigan State University), Hannah Burrack (NC State University), Cesar Rodriguez-Saona (Rutgers University), Phil Fanning (University of Maine), and Vaughn Walton (Oregon State University).

Fruit IPM for 9/15/21
Blueberries:
Putnam Scale: As of the past week, scale crawlers have tailed off. For all practical purposes, treatments for the second generation are done.
Sharpnosed Leafhopper (SNLH): We are calling the second generation trap peak occurring over the last week to 10 days. Therefore it is time to treat this generation if you have not already done so. Use any of the sucking insect materials listed in the 2021 Commercial Blueberry Pest Control Recommendations For New Jersey. Suggested materials include Diazinon, Imidan and any neonicotinoid such as Assail, Actara and Admire. Pyrethroids are also labeled, but are slightly less effective.

Grower and Winemaker Town Hall: Questions from the Field and Cellar
Eastern Viticulture and Enology Forum has planned a virtual meeting on September 7th @ 3:00 PM ET. Here, regional viticulture and enology specialists will present a Grower and Winemaker Town Hall virtual meeting series to give seasonal updates and answer pre-submitted and live questions from grape and wine industry stakeholders.
The structure of these meetings depends on pre-submitted questions. Please email Hemant Gohil at gohil@njaes.rutgers.edu if you have any question. Please see below for the topic area suggestions for the September 7th meeting. [Read more…]

Fruit IPM for 8/18/21
Grapes:
Drosophilds and Sour Rot: 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, + Oxidate 2.0 has been found to be helpful. Other sterilants can also be used. 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. [Read more…]

Fruit IPM for 8/11/21
Brown Rot: Brown rot pressure remains very high. Make sure to alternate fungicide chemistries or FRAC groups. See page 179 of the Tree Fruit Production Guide for the most effective products and Table 7.7 on page 154 for a summary of fungicide efficacy and FRAC groupings reprinted below: [Read more…]
