Fire blight is a devastating disease of apple and pear caused by a bacterial pathogen. The disease is traditionally controlled with antibiotics, but in this webinar, you will learn about a non-antibiotic alternative—an integrated method that uses a biological control and a surface sterilant. Whether you are an orchard grower who wants to market your fruits as antibiotic-free, or an arborist or landscape practitioner who cannot use antibiotics at private homes and schools, this webinar may provide a solution for you.

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

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.
