-5- 



in the overwintered leaves — when applied at the same rate (500 - 600 gal- 

 lons per acre). This rate, hov;ever, may supply more nitrogen than is needed 

 for some orchards. 



Q; Are there any advantages of using Fermate over v/ettabla sulfurs in the 

 apple spray program? A: Yes. (1) its use vj-ith lead arsenate, and v/ithout 

 lime, will produce muc'h~less fruit russet on Baldwin, Delicious, etc.; 

 (2) the mixture of Fermate one-half pound and one-half dosage of sulfur 

 gives better control of apple scab than full dosage of sulfur or Fermate, 

 and as good control of cedar rust as a full dosage of Fermate (1^ - 100). 



Q: How much Fermate should a dust contain? V/hat is the filler in a Fermate 

 dust? A; A Ferroate dust for varieties subject to fruit russet should con- 

 tain lOjfTermate (remainder talc or talc and lead arsenate). For non-russet- 

 ing varieties, it should contain b% Fermate (remainder dusting sulfur or 

 sulfur and lead arsenate). 



Q; Vfiiat is the best spray program for Baldwin and Delicious to control 

 pe^sts without russeting the fruit? A: Use Fermate 1-|- - 100 in pre-blossom, 

 calyx and first cover sprays (or through second cover if cedar rust is con- 

 cerned), followed by Fermate 1 - 100 in later covers. For supplemental dust, 

 use Fermate-talc dust (see preceding paragraph). 



^j Is a ground spray of Elgetol v/orthwhile for fruit crops other than apples? 

 If so, which fruits and for what diseases? A; Yes, for brovm rot of stone 

 fruits (4 quarts - lOO); pear scab (2 to 4 quarts - lOO); and for black rot 

 of grapes (2 quarts - 100 on vines, 4 quarts - 100 on ground) — before green 

 tissue is exposed. 



(^; V/hat constitutes a good v/ettable sulfur? A: A sulfur that contains the 

 right amount of a wetting agent that is compatTble v/ith other standard spray 

 materials; and a mixture that contains at least half of its sulfur in par- 

 ticles less than 10 microns in diameter. The degree of coverage and the 

 interval between sprays are at least as important as the particle size in 

 the sulfur preparation — probably more important. 



<^i On an equal sulfur basis will the best wettable sulfur products control 

 apple scab as well as lime-sulfur? A: Although the best wettable sulfurs 

 are the equal of lime-sulfur in preventing scab infections when applied 

 ahead of rainy periods, yet a succession of wettable sulfur sprays is not 

 as effective as a succession of lime-sulfur sprays because the latter have 

 a post-rainy period effect in preventing scab infections as well as an 

 eradicative effect on established new scab spots, which wettable sulfurs 

 do not have.

(News itom in The Packer) Northampton, Mass., Jan. 4 — It didn't 

 take H. I. Bean, 86, of Northampton, long to get rid of his 1945 

 apple crop. Bean just sat under a tree and ate the entire crop — 

 one apple. He had hoped for a harvest of 2,500 bushels but a freez* 

 depleted his crop.
