New York AGRICULTURAL EXPERIMENT STATION. Pak 
THE ELMIRA EXPERIMENT. 
Conducted by John Strouse, Elmira, N. Y. Nineteen acres 
of potatoes (in three lots) were sprayed all over four times 
and 13 acres a fifth time. The sprayer was a two-horse, 6-row 
“Perfection ” sprayer carrying one nozzle per row. Part of 
the water for the bordeaux came from a creek near the field 
and the remainder from a well about 80 rods distant. In two 
of the lots 3-row checks were left. Both checks were treated 
with paris green once—about July 12. In the first spraying 
paris green was used with the bordeaux at the rate of two 
pounds to 50 gallons. In one of the later sprayings arsenite 
of soda was used with the bordeaux at the rate of 4 qts. of 
the stock solution to 50 gals. The checks were not injured 
by bugs. There was no blight and very few flea beetles. Lot 
No. 1 suffered severely from tip burn, but Lots II and III were 
very little injured bv anything.

The test rows yielded as follows: 
Lot No. 1. Sprayed five times; rows 485 ft. by 3 ft. 
Two sprayed rows, 230 Ibs.==57.4 bu. per acre. 
Middle unsprayed row, 113 Ibs.=55.9 bu. per acre. 
Gain, 1.5 bu. per acre. 
Lot No. IfI. Sprayed 4 times; rows 517 ft. by 39 in. - 
Two sprayed rows, 424 Ibs==91.6 bu per acre.
