THE CANADIAN HORTICULTURIST

state I did not arrive in Rochester in time 

 to hear the discussion on "Dust Sprays," 

 but I, nevertheless, heard a great deal 

 about it from Mr. D. Johnson, Dominion 

 Fruit Commissioner; Mr. Walter Dempsey, 

 of Trenton; Mr. W. F. Kydd, Toronto, and 

 from many others who were there. The 

 fruit growers seemed inclined to accept the 

 statement of the experimenters with regard 

 to results secured, and these results I may 

 say show satisfactory returns for codling 

 moth and scab when compared with re- 

 sults of careful spraying. Unfortunately, 

 the dust idea seems at present to be lim- 

 ited to codling moth, and scab, and will 

 not apply in the case of San Jose Scale, 

 peach leaf curl, or pear psylla, at least at 

 present. 



The advantage of working with dust is 

 that one man and one horse can do con- 

 siderably more work in one day than can 

 be done by three men and two horses with 

 an ordinary power sprayer. The dust out- 

 fit costs from $125 to $250, and it is claimed 

 that forty acres of bearing apple orchard 

 can be thoroughly dusted in one da>. 



The Ontario delegates were much inter- 

 ested in the work of the New York State 

 Commissioner of Foods and Markets, which 

 was thoroughly discussed before the con- 

 vention, and which received from the con- 

 vention a very hearty vote of confidence. 

 The commissioner is, of course, a govern- 

 ment officer, but the strange thing is that 

 he is established in business for the pur- 

 pose of marketing New York State food • 

 products. Any grower in New York State, 

 or for that matter in any other state, may 

 consign a shipment of any size to the com- 

 missioner. The goods are handled under 

 contract with one of the large auction sales 

 rooms, and a five per cent, charge is suf- 

 flcent to place the shipment into the hands 

 of the retailer. 



DUST SPRAYS. 



Very successful experiments in the use of 

 dust snrays have been carried on in New 

 York State, for several years. Cornell Uni- 

 versity of Ithica, New York, have been ex- 

 perimenting for five years and this year 

 have issued a bulletin No. 369, showing the 

 results of their experiments and the many 

 advantages of dusting. 



During the recent New York State Fruit 

 1 irowers' Association the most important ad- 

 dress at the meeting was one by Professor 

 Reddick on the use of dust sprays. He told 

 the growers that they would have to use 

 dust, particularly those who have large or- 

 chards and find it impossible to get over 

 their spraying in three or four days or who 

 have trouble securing labor. 



He showed twelve different advantages of 

 dusting over spraying for summer applica- 

 tion. The most important of which was the 

 great saving in time and labor. Our man 

 with a dusting machine being able to do 

 more work in one day than three men with 

 a power sprayer would do in four days. 



Besides these experiments the Niagara 

 Spray Companies have been carrying on 

 some extensive investigations and during 

 the past year dusted a good many large or- 

 chards. They have issued a special bulle- 

 tin on the result of their work. 



The Niagara Companies have always been 

 foremost in all matters of sprays. They 

 have worked out the most approved and up- 

 to-date dusting machine in the world. They 

 have installed complete machinery for 

 grinding and preparing all kinds of dust 

 sprays, so are in a position to take care of 

 any requirements for either machines or 

 materials. 



The Niagara Brand Spray Co. of Burling- 

 ton, will be pleased to give any information 

 on this important subject.
