  • ReTain Recommendations -- Apples

    ReTain Recommendations for Harvest Management -- Apples (and pears and peaches)

    From Jim Wargo, Valent USA

    Thanks to Jim and UConn's Mary Concklin where these recommendations appeared in her e-mail newsletter...

    ReTain Recommendations -- Apples

  • ReTain on peach, nectarine, and plume for harvest management and improvement of fruit quality

    August 1, 2019

    A reminder that ReTain can be used on peach, nectarine, and plum for harvest management and improvement of fruit quality. From the ReTain label: Depending on cultivar, orchard conditions, and grower objectives, one or more of the following benefits will be associated with using ReTain on peach, nectarine, or plum:

    • Improved harvest management

    • Additional time for increase in fruit size

    • Maintenance of fruit firmness

    • Reduced preharvest fruit drop

    • Improved fruit quality

    • Enhanced storage potential

    Apply one pouch per acre of ReTain to peach, nectarine, or plum one to two weeks prior to the anticipated beginning of the normal harvest period* of untreated fruit. ReTain efficacy requires that fruit and foliage receive thorough spray coverage. To ensure thorough coverage adjust water volumes based on tree size and spacing and use calibrated spray equipment (i.e., orchard air blast sprayer). Excessive spray application volumes that result in spray runoff will reduce product performance. In most cases, 100 gallons per acre has been shown to be effective.  For optimal response, use ReTain with a 100% organosilicone surfactant. Use a final surfactant concentration of 0.05 to 0.1% (v/v) in the spray tank. To reduce foaming, add the adjuvant last and minimize agitation.

    *The normal harvest period for a particular orchard block refers to that time when fruits not treated with ReTain would be harvested. To help determine the beginning of the normal harvest period, refer to historical trends for harvest dates and the “days from full bloom to harvest” interval for each cultivar in your area, and closely monitor the fruit maturity development for the current season.

  • Spotted Wing Drosophila on the Rise

    July 25, 2019

    With the heat wave and dry spell broken, for now, we are seeing an increase in SWD numbers in our monitoring traps.  This means, of course, it's time to make sure you are up to speed on your management practices! Check out the Quick and Dirty SWD Recommendations for an overview and links to more detailed information.

    SWD alert as fruit ripens!

    June 25, 2019

    As fruit ripen they become susceptible to spotted wing drosophila (SWD) infestation. Right now that includes strawberries, and very soon cherries and blueberries. Followed not long after by peaches and nectarines. We are catching SWD in traps! For the latest SWD management information, see the SWD sidebar link or click here. Here are direct links to insecticide recommendations for small fruit and stone fruit. Good luck!

  • Pollen Tube Growth Model on NEWA

    May 7, 2019
    Bloom Thinning with the Pollen Tube Growth Model (PTGM) Mike Basedow, CCE-ENYCHP & Dan Donahue CCE-ENYCHP Reprinted from Cornell ENYCHP Tree Fruit E-Alert, Donahue and Basedow, for April 30th, 2019 @ 10:00 am We trialed the PTGM thinning protocol in ENY orchards in 2018 to mixed results. Spray timings are critical (hours, not days), and inclement weather can interfere. Trials have been set up in Ulster, Columbia, and Clinton Counties for 2019.
