Aug. 10th, treated each row the same as above, except that rows 

 No. 4 and 5, which were somewhat injured by the copper solution, 

 were sprayed with tlie Bordeaux mixture and Paris green, one pound 

 to 200 gallons, and No. 7 and 8 with the same, the plaster not being 

 a fungicide and the sludgite not having had any efteet on the potato 

 beetles. 



Results. August 14th, rows 1, 2, 3, 4 and 5 showed a little leaf 

 blight; rows 7, 8, 10, 11 and 12 were entirely free, and row 9 very 

 badly blighted. Row 6 showed serious injury from the ammouiacal 

 carbonate of copper. 



August 17th, rows 4, 7, 8, 10, 11 and 12 showed a little blight; 

 rows 6 and 9, foliage nearly all dead. At the end of the season's 

 growth, it was found that rows 4 and 5 remained green much the 

 longest, showing that the sulphate of copper used July 14th retained 

 its effect somewhat through the season. 



Noinjury was noticed where Paris green was used with the Bor- 

 deaux mixture at the rate of one pound to fifty gallons of water. 



REPORT OF DR. JABEZ FISHER, 



FITCnUURG, MASS. 



"My obligations are due to the Station for an equipment during the 

 past season of materials and implements for the purpose of investi- 

 gating the suliject of spraying trees and plants with insecticides and 

 fungicides* with a request to report all that could be learned that 

 might be of use to fruit growers. The paucity of results renders it 

 undesirable to give in detail all the operations that have been carried 

 out, but in a general way I will attempt to give the gist of them. 



Having suffered considerably for five previous years from various 

 fungous diseases of the-" different fruits, I devoted considerable 

 attention to preparatory, preventive treatment. The orchards 

 being in grass, I burned the stubble about April 15th so far as 

 possible, and then sprayed the trees with sulphate of copper solution 

 one pound to twenty-five gallons. Three vineyards of an acre each 

 were treated, one with sulphate of iron, one pound to two gallons; 

 one with Bordeaux mixture, and one with sulphate of copper, one 

 pound to twenty-five gallons, well sprayed over the vines and trellises
