good control of scab may be obtained without it, just as has been done 

 in many past seasons, 



Yfaere No Iron Carbamate is Available* To reduce fruit russet in 

 Baldwin and~Delioious, use pr^erably a wettable sulfur < or Puratized, alone 

 in the pre-blossom, bloom and calyx sprays. If lead arsenate is necessary 

 in the pink or calyx sprays, then add as much hydrated spray lime as lead 

 arsenate to the spray mixture. In the first and second covers, give pre- 

 feronce to Puratized and lead, otherwise use the sulfur-lead-lime mixture. 

 For later covers, adhere to the standard fungicide - insecticide program 

 indicated in the printed spray chart. 



In the absence of Fermat^ or Karbam, iMsts of apple may be reduced 

 slightly by the usual sulfur program provided one or two applications are 

 made during bloom. It is mandatory that the fungicide be on the trees 

 shortly before or during the infection rain. 



In orchards where Brooks' spot or bit-t>cr rot is a problem, iron carbamate 

 may be replaced by Bordeaux 2-6-100 in the second cover and by 4-8-100 in 

 the third and fourth covers -- or by neutral copper fungicidal powders to 

 give ^ lb, and 1 lb., respectively, of metallic copper to 100 gals. In the 

 last instance, add as much spray lime as neutral copper fungicide,

A plum Puzzle ; At the Flower Show in Boston a 

 lady stopped at the horticultural information booth 

 to inquire about a plum tree v/hich had died and had 

 later sprouted up from the lov;er part of the trunk, 

 "But now", she said, "I have a peach tree instead 

 of a plum tree". The explanation is that some 

 nurserymen propagate part of their plum trees on peach 

 seedlings presumably to get a better root system on a 

 sandy soil.
