For orchards in southern Maine, we are about about 21 days from first pick on Macs and Honeycrisp.<\/p>\n<p>ReTain can extend the harvest window by preventing preharvest fruit drop. I anticipate that ReTain effectiveness will be less than normal in orchards that are experiencing water stress. Two applications are allowed, but I do not know how well this will work with the dry conditions. ReTain is more effective when applied as a dilute spray (2X) rather than with a greater concentration.<\/p>\n<p>ReTain can be combined with NAA to prolong drop control. For McIntosh, apply Retain at the full rate with an NAA product at 10 ppm (4 fl. oz. per 100 gals. dilute equivalent) at three weeks before first harvest. A second application may be needed to prolong drop control of McIntosh. Honeycrisp is more sensitive to ReTain than McIntosh and will experience a greater delay in ripening.<\/p>\n<p>Do not apply with calcium chloride as this can burn fruit and foliage.<\/p>\n<p>For more information, visit this PennState website authored by Jim Schupp: <a href=\"https:\/\/extension.psu.edu\/apple-pgrs-prevention-of-preharvest-drop-in-apple-orchards\" target=\"_blank\" rel=\"noopener\">Apple PGRs &#8211; Prevention of Preharvest Drop in Apple Orchards<\/a><\/p>\n<h3>Fruit Maturity at Highmoor Farm<\/h3>\n<p>Peach varieties that are ready to pick this week:<\/p>\n<p>Donut peaches: TangOs and BuenOs2<\/p>\n<p>Regular peaches: Starfire and an unknown mixed in with July Rose that is probably White Rose<\/p>\n<p>Starch index in Paulred is still 2.2, so no change in starch breakdown since a week ago.
