Dusting for tender fruits and apples, L. Caesar {Ann. Rpt. Fruit Oroicers' 

 Assoc. Ontario, 48 {1916), pp. 47-51). — A comparative test of dust and liquid 

 sprays was carried out in 1916 on apples, plums, sweet cherries, peaches, and 

 grapes in various orchards in Ontario. 



Although the results were somewhat in favor of the dust method in this 

 experiment, less favorable results from dusting were reported by others in 

 Ontario and in New York State. Hence it is recommended that growers do 

 not purchase dusting machines until further comparative studies have been 

 made.
