1 Of these 42 growers malring a fall Bordeaux spray for anthraenose, 10 made an additional spray during 

 the summer with Bordeaux alone for apple scab control, using a strength of 4-4-50 as compared to a 6-6-50 

 strength for the fall spray. 



As a general rule a final spray is applied in the fall for anthrae- 

 nose. Nearly 78 per cent of the growers use this spray. It is a dor- 

 mant spray, applied after harvesting the fruit, and is made with a 

 6-6-50 mixture of Bordeaux. It often takes a little longer to apply 

 than the other dormant sprays or the lead arsenate spray, because 

 of the time required for mixing the ingredients. 



In Table XIV spraying practices are summarized. On account 

 of the great number of different practices followed in spraying, no 

 attempt has been made to arrange this table according to the time of 

 application. The average number of sprays of all kinds used for all 

 orchards is 5.65, and the total cost for material and labor for these 

 sprays is $17.54 per acre, or practically $0.08 per box. 



MISCELLANEOUS. 



There are many items of orchard labor which may be classified 

 as miscellaneous. Summer pruning is included in miscellaneous 

 labor, as are all such items as doctoring trees, painting wounds, care 

 of lateral ditches for the orchard not included in irrigating time, 

 and any other odd items which may appear. For these miscellaneous 

 items there was found to be a labor cost of $2.03 per acre for the 

 clean-cultural orchards, $1.17 per acre for those under the mulch-crop 

 system, or $1.65 per acre for all orchards. The cost per box was 

 $0.0074.
