Fruit Times

November 18, 2016

After a busy harvest season, there are still several jobs to be done and one of those important jobs is pruning.

The Penn State Extension Tree Fruit team has created new videos for fruit growers. These ten minute ‘Learn Now’ videos are short, to-the-point guides explaining topics that are fundamental to commercial orchard intensification and efficiency.

Growers can get a jump on disease management for the 2017 season this fall. This month’s article will be a review of tips to manage apple scab, peach leaf curl, and cherry leaf spot.

With the onset of colder temperatures at the end of the harvest, there are still things that need to get done in the orchard before winter.

Honeycrisp is a wildly popular apple variety. While it has outstanding crispness and flavor, it has its faults.

During August and September we saw apples mature a bit earlier than normal. Once mature, they quickly tree-ripened. The hot, dry weather and full sun exposure of tall-spindle trees compressed the harvest window. This earliness and rapid ripening has continued with Fuji and Cripps Pink.

During the last four weeks we have observed a very sharp increase in the number of brown marmorated stink bug (BMSB) adults collected in various monitoring traps placed around orchards located in southern Pennsylvania. After relatively lower levels of infestation on fruit observed during the last two seasons, this 2016 harvest seems to bring back a serious BMSB challenge.

During August and September we saw apples mature a bit earlier than normal, but once mature, they quickly tree-ripened. Due to the hot, dry weather, and the full sun exposure of trees managed as tall-spindles, the harvest window was compressed. This week, we began sampling late-season varieties, Fuji and Cripps Pink. While Fuji fruit lacks red color, fruit ripening has already begun.

The purpose of safety data sheets (SDS) is to provide detailed information about all chemicals and pesticides including the chemical properties, various hazards (e.g., physical, health, environmental, etc.), protective measures, and safety precautions (e.g., handling, storing, and transporting).

There have been many reports of bitter rot on apple while fruit are being harvested. With Mother Nature recently dumping a ton of rain, which will have washed off any plant protection materials, growers are encouraged to apply protectants to apple varieties that have yet to be harvested. Tips for identification and late season management are discussed.

During our August and September sampling we have seen apples mature a little earlier than normal, but then quickly tree-ripen. Between the hot, dry weather and the full sun exposure of trees on size-controlling rootstocks, the harvest window for each of the early varieties has been compressed. Fruits moved quickly from storage-ready to tree-ripe and when left unharvested became destined for cider. This rapid tree ripening can lead to softer apples with poorer quality of late-harvested fruit destined for cold storage.

Daybreak Fuji fruit were surprisingly soft, with a median firmness of 13.2 pounds.

Fruit have quickly progressed from storage-mature to tree-ripe. In many cases fruits in commercial orchards have softened quickly and wound up being picked for cider. This rapid ripening may also reduce the quality of late-harvested apples, and growers are advised to carefully time harvest based on maturity indices.

The numbers of brown marmorated stink bug adults are increasing in many orchards. Codling moth adults will be active for at least another 2 to 3 weeks. The fourth generation Oriental fruit moth adults are likely to be present in orchards during all of September and into October.
