New Penn State Tree Fruit Production Guide to be Available at Winter Tree Fruit Meetings


Posted: February 14, 2014

The 2014-2015 Penn State Tree Fruit Production Guide has been updated for the 2014 growing season. In our goal to make the guide as comprehensive as possible we have added sections on postharvest disease control, marketing, the Geneva rootstock series and native pollinators.

The process of updating the guide begins back in September. Highlights in the new guide, as always, are additions and deletions of fungicides, insecticides, herbicides, and plant growth regulators. Changes in labor regulations, production budgets and food safety have been incorporated into the appropriate sections.

There are many changes in the Pre-harvest Interval (PHI) and Re-entry Interval (REI) for materials in Table 4-15 on pages 223 to 225. The guide has always stressed an Integrated Pest Management (IPM) approach to pest management and recently has also stressed chemical resistance management. The resistance management strategies are based upon ensuring that no one mode of action for a chemical is used repeatedly. To prevent the earlier development of chemical resistance there are tables in the guide indicating the mode of action of the chemical. These tables are referred to as the IRAC (insecticides) FRAC (fungicides) and HRAC (herbicides). The IRAC list is in Table 3-7 on page 207; the FRAC list is in Table 3-8 on page 208 and the HRAC table on page 9. The section on pollination and pollinators has been revised. It now includes a listing of wild bees; management of the solitary Osmia species; native wildflowers, trees and shrubs that are beneficial to wild bees as well as the active months for various wild bee populations.

New information about diseases such as Alternaria Leaf Blotch, Bitter Rot, Black Rot, Gray Mold of pome fruit; Moldy Core of apple and Peach Scab has been added. Table 2-2 on page 105 has been added to help determine rust infection periods based upon temperatures and wetting period. Information on the use of urea as a fall foliar spray to reduce overwintering inoculum for apple scab was added. A new section on controlling postharvest diseases was added. Information on some of the new Geneva apple rootstocks was added. New plant growth regulators include PoMaxa and Blush, and a new use of Promalin for recovering from frost damage is in the guide.

In our goal to make the guide as comprehensive as possible we have added an entire chapter on Marketing (Chapter 10). This chapter, written by Dr. Kathy Kelley, covers information on customers, segmenting, influence of generation and ethnicity on their purchasing habits and how to attract them. There is information on how to set up a retail outlet, how to most effectively display merchandise, and floor plans that can increase sales. The chapter has a section on the use of various social media, web sites, tracking customer preferences and use and evaluating the success of promotions and loyalty programs.

The cost of the guide is $35.00 + postage. You can save postage by picking up a copy at the Winter Tree Fruit Educational Meeting in your area. The county offices will have copies on hand but it is best to check with them before visiting the office to purchase a copy.
