SPRAYING IN NURSERY AND ORCHARD. 



It is a pleasure to note a very general awakening amongst 

 orchardists and nurserymen along this line, as evidenced by 

 numerous letters and inquiries. 



We have initiated a series of experiments in different parts 

 of the state with both liquid and dust sprays, but prefer to do 

 more work before reporting. Briefly, we may say, that in one 

 nursery where liquid Bordeaux was used, and where 200 rows 

 of nursery stock were sprayed, each row 80 rods long, the 

 season's work called for 38^ barrels of the solution, and three 

 men and one team were employed for what was equivalent to 

 five days' time. The season's spraying, labor and material 

 cost about $38.00. The field workers in charge reported in 

 November generally good results ; that the stock made excel- 

 lent growth during the latter part of the season, etc., but in 

 this case it would have been impossible to personally superin- 

 tend the experiment, and the work was not done as systemat- 

 ically as might be desired. More detailed results are expected 

 next year. 



Another orchardist in Norman County sprayed his Plums 

 and Apples thoroly in April with liquid Bordeaux (4-4-50), 

 and in October reports trees and fruit free from fungus, a 

 result which he attributes to the spraying. 



On our experimental garden at the Station we sprayed our 

 nursery trees with weak Bordeaux (3-6-50) on May 28tli. 

 June 2nd and June 25th. The trees were kept generally free 

 from fungus, but the spraying appeared to have but little effect 

 upon the disease known as Shot-hole Fungus. 



Mr. Fred Mohl, a progressive orchardist and nurseryman 

 and a prominent citizen of Adrian, Minnesota, is an enthu- 

 siastic supporter of the dust spray, and certainly an examina- 

 tion of his well kept nursery, showing a marked absence of 

 insects and fungus diseases, goes far to substantiate his claims 

 for this method. He declares that the cost of applying dust 

 will not exceed one half the cost of liquid spraying, and that
