N 'tes v;o presontod the now notes pertaining to insecticides. Y»"o include 

 herewith the notes on fungicides, dusts raid miscellaneous materials. 



Protectant Fungicides, The follovv'ing are acceptable: 



Dry Wettable Sulfur 



Paste Wet table Sulfur 



Hvj Lime Sulfur 



Liquid Lime Sulfur 32*^ Baiome 



Iron Carbamate (Formate, Karbam) 



Puratized Spray 



Except for Puratized, aftc-r Calyx the amount of fungicide may 

 bo reduced gradually, if the Scab has been controlled well by the early 

 sprays, but the quantity should not bo less than one-half of the original. 

 Ylhen applied to v/et trees or during, rains the concentration should be 

 incr'jased by one-third to one-half. One-half pound of iron carbamate, 

 such as Fermate or Karbam, combined v;ith half strength wetfeabio sulfur 

 is more effective a,,ainst Scab than either alone and is effective for 

 Cedar Rusts. Iron carbamate is advised for controlling the Cedar Rust 

 diseases, Brooks' Spot and Bitter Rot. A bloom application is usually 

 necessary to obtain good control of the Cedar Rusts. 



To avoid fruit russeting iron carbamate is preferred on Baldwin 

 and Delicious. Do not use sulfur in combination v/ith lead arsenate 

 on these varieties, Tne use of lime sulfur, especially the liquid form, 

 is injurious, particularly vihen used with lead arsenate and at temperatures 

 above 85° F. Limo should be omitted in all sprays containing Iron c»rbaiaate 

 and Puratized, In sprays containing wettable sulfur or lime sulfur 

 ajid lead arsenate the addition of the sarao amount of hydratod lime 

 as lead arsenate tends to reduce arsenical injury. Use freshly hydrated 

 300 mesh high calcium (70$^ calcium oxide) lime. 



To avoid objectionable residue Puratized should not be used after 

 mid-JunJ« For protection against Scab up to the early Cover sprays, 

 it is the equal of wettable sulfurs or ircoi carbamate but is not effective 

 for Cedar Rust control, 



Eradicant Sprays For Burning Out Scab, Foliage Scub ctin be burned 

 out" ~o'as~iabl y welT "^'.Ith Tiqua'd'TTiiiicPs u 1 f u r 2 gallons (or dry 3 lbs.) 

 or Puratized, 1 pint. Unlike lime sulfur, Puratized eradicates Scab 

 vv'ithout causing foliage injury. It is usually necessary to apply 

 eradicant sprays more heavily and more thoroughly than protective sprays. 



Dusts, In many cases, dusting is desirable: 



1, As emergency treatments between scheduled spray applications 

 for Scab and Cedar Rust control, 



2, V'ilion a v/ater supply is limited or unavailable, 



3, ¥ihen iin.,iodiate application is more important than delayed 

 spraying, 



4, To protect non-bearing trees from severe infestation, 



5, To avoid excessive rosidu-^j in applications just before harvest*!
