rain begins, but it may also cause serious damage to foliage and 

 fruit. (See Note 17). 



Note 4, In the combined spray of vmttable sulfur and lead arsenate, 

 the addition of tv/ice as much lime as lead arsenate tends to reduce 

 arsenical leaf injury and fruit russet. Use a freshly hydrated, 300- 

 mesh, high calcium (70^^ calcium oxide) lime. Line is not needed in 

 spray mixtures containing Fermate or puratized, and should not be 

 added to them, (See Notes 5, 17), 



Note 5, Fermate 1^ - 100, or -g- - 100 plus one-half dosage v;ettable 

 sulfur^ is far more effective than sulfur alone against cedar-apple 

 and quince rusts, and is equally or more effective for apple scab and 

 black rot. On Baldwin, Delicious and other russet-susceptible var- 

 ieties, use Fermate 1-g- - 100 through Second Cover, followed by 1 - 100 

 in later sprays. Omit lii.ie in all Fermate sprays. Fermate 1-g- - 100 

 in Second and later Cover sprays affords much better protection against 

 Brooks' spot and bitter rot than sulfur sprays. 



Note 6, Vflaenever the blossom period promises to be rainy and prolonged, 

 a spray or dust of sulfur or Fermate will be needed around mid-bloom 

 on scab-susceptible varieties, vrtiile either Fermate or a mixture of 

 Fermate and sulfur (See Note 5) should be applied at that time on rust- 

 susceptible varieties. 



Note 13. (Add follov;ing to old Note 13): Puratized spray is equally 

 effective against scab and does not injure foliage or fruit. (See 

 Note 17.) 



Note 15, (DDT) Wettable powder at rate of 1 pound DDT in 100 gallons 

 (ii pounds 50% powder; 2-g- pounds 40^3 powder; or 5 pounds 20_5o powder) 

 has controlled codling moth. Because of residue toleranco (7 p. p.m.) 

 only 2 or 3 applications arc advised. Applications at 2nd Cover and 

 in Emergency Spray A are suggested. If codling moth is abundant, a 

 third application at 4th Cover period may be made on varieties later 

 than Mcintosh. Do not use DDT vdth lime. If red mite increases after 

 DDT sprays, use Emergency Spray B. Information on control of codling 

 moth v;ith DDT dust is incomplete. (This Note will be mentioned in 

 the 2nd Cover, 4th Cover, and Emergency Sprays A and B,) 



Note 16 . A spray of Elgetol -g- to 1 gallon - 100, or sulfate of am- 

 monia 100 pounds - 100, or nitrate of soda 100 pounds - 100 plus cal- 

 cium arsenite 4 pounds - 100, applied to the orchard floor between 

 green-tip and pre-pink at not less than 500 gallons per acre, so as 

 to insure wetting of all exposed leaves, will greatly reduce scab 

 ascospore formation in the overwintered leaves. These sprays will 

 injure nev;, green leaves. 



Note 17 . Puratized spray is more effective than v/ettable sulfurs 



for preventing scab infections, and is as effective as lime-sulfur 



in burning out scab spots without injuring leaves and fruit. Hov^ever^ 



it is not plentiful this year. To avoid mercury residue, it should 



not be used in successive applications later than the First Cover spray, 



nor later than June for the Emergency Spray A to burn out scab. Do 



not add lime to Puratized spray.
