Massachusetts, Michigan and Nev; York are practically free from it. Since 

 bushes infected vrith stunt neither grov/ nor produce well, the purchaser 

 should protect his ovm interests by insisting on healthy plants. 



The demand for plants, both among commercial grov/ers and home gar- 

 deners, has been very heavy the past few years, so heavy, in fact, that 

 propagators have had difficulty in keeping up with it. Because of the short 

 supply, anyone wishing to set blueberries next spring should get his order 

 in early.

AIOTCRS TO qUESTIUNS ON DISEASES AJTD FUNGICIDES IN M. F.G,A. "BLUE LIST" 



<^i Did wettable sulfurs control scab in 1945? A: In some cases it did — 

 mostly (1) where there vms a very light carryover of the scab organism in 

 the orchard; (2) where the usual or a larger number of sprays (and supple- 

 mentary dust applications) were applied; and (3) where spraying was thorough 

 and timely. 



1^; How can I clean up a scabby orchard? A: Any one of the following pro- 

 cedures should enable a grov/er to control apple scab satisfactorily in an 

 orchard with a heavy carry over of scab — even if the season is v/et: (a) 

 Spray the entire orchard floor and adjacent borders with Elgetol 2 to 4 

 quarts to 100 gallons preferably betv^een green tip and full delayed-dormant 

 (or at dormant if the same spray is to be applied to the trees for insect 

 control), using 500 - 600 gallons per acre on the ground. Follow with usual 

 wettable sulfur schedule. (b) Spray with liquid lime-sulfur 2 - 100 in pre- 

 pink to first cover spray, inclusive, followed by wettable sulfur in remainder 

 of covers. (This schedule would probably cause severe injury to all var- 

 ieties sprayed.) (c) Use wettable sulfur (or Fermate, or sulfur plus Fer- 

 mate) program as usual, but increase the dosage (in the tank) by at least 

 one-third for applications through first cover; and spray more frequently 

 than usual; make sure to have the spray, or a dust, on ahead of or during 

 infection periods; and be more particular than usual regarding thoroughness 

 of coverage. 



<^: Yfill Puratized be available for apple growers in 1946? How about mer- 

 "cury residue? A:The supply of Puratized Agricultural Spray will be limited, 

 according to the distributor. According to fruit analyses made in 1945, no 

 mercury residue was found v/here Puratized N5-E was used in first four sprays 

 (pre-pink to first cover, inclusive). 



Q_; Is scab likely to be any earlier than usual next spring? A: In view 



of premature defoliation in scabby trees last summer and fall, scab ascospores 



should mature somewhat earlier this spring — ■unless there is an unusually 

 heavy and late snow cover. 



Q: What sprays other than Elgetol may be used to eradicate the apple scab 

 Tungus in the overwintered leaves? As Sulfate of ammonia 100 pounds - 

 100 gallons, or nitrate of soda 100 'pounds - 100 gallons plus 4 pounds cal- 

 cium arseuit«, should equal the Elgetol spray for killing the scab organism
