ERRATA YADDA YADDA

After a long and involved reformatting process, the 2000 edition of the Tree Fruit "Recommends" (now disingenuously renamed "Guidelines" to placate certain legal minds who evidently don't think Cornell should be recommending anything) has finally been delivered and should be making its way to all intended readers. Although inexcusably late – a thousand pardons, but publishing is not an exact science – we feel that this new format represents a much-needed improvement over its predecessor, and that it will be easier to first of all find, and ultimately use, all the information it contains. Within the next week, this publication should also be available in pdf format on the web.

Following the age-old tradition of continually revising our advice even as it is being dispensed, we need to point out a couple of glaring errors that got by us, and tentatively ask your gentle assistance in passing along to us any further errors you may happen upon, preferably in a non-threatening manner:

• Of most immediate concern, the main thinning table on page 103 (Table 21b) is missing several tabs on many of the varieties, which shifts thinning recommendations to the wrong timings (bloom instead of petal fall, petal fall instead of 10 mm, etc.). This is a very serious error that will lead to major thinning problems if growers follow what is printed. The hard copy version of this newsletter contains inserts of errata sheets with the correct formatting of these tables. Furthermore, each of the county and regional fruit specialists has been provided with copies of the corrections for distribution to their growers; contact your CCE Fruit Extension Staff if you need one.

• In Table 20, the Apple Pesticide Spray Table, the PHI value for Asana is incorrectly given as 28 days instead of 21. This error is found on pp. 85 (tarnished plant bug), 86 (leafminers), 89 (green fruitworms and OBLR), 91 (tarnished plant bug), and 95 (OBLR).

• The captions were omitted from the last two photos in each series of figures that show the growth stages of all the respective fruits, except apples. The following entries should be made for:

Fig. 16 (Pear, p. 110): 7. Petal Fall; 8. Fruit Set

Fig. 17—18 (Tart Cherry, p. 120—121): 6. Petal Fall; 7. Fruit Set

Fig. 19 (Peach, p. 131): 7a. Fruit Set, shucks on; 7b. Fruit Set, shucks off

Fig. 20 (Plum and Prune, p. 144): 7. Petal Fall; 8. Fruit Set
