PIats 44 and 110. —Sprayed every twenty days with ammoniacal solution; was not 
so suceessful as plats 38 and 104, treated every ten days with the same preparation. 
Plats 46 and 112. —Sprayed every twenty days with potassium sulphide solution; 
gave little or no effect in preventing rust, hut yielded better than the adjoining un¬ 
treated plats. 
Plats 48and 114. —Seed, soil, anti spraying treatments with Bordeaux mixture; seed 
immersed twenty-four hours, soil treated with one-half gallon to 20 feet of row, and 
plants sprayed every ten days. This treatment was well nigh fatal, giving the light¬ 
est yield of any group in the whole tract; very little rust. 
Plats 50 and 116. —The treatment of these plats was exactly the same as the preced¬ 
ing, only potassium sulphide was used instead of Bordeaux mixture. The results 
were very unsatisfactory and, the yield light; very little rust. 
Plats 52 and 118. —Seed, soil, and spraying treatments with ammoniacal solution of 
copper carbonate; plants sprayed every ten days and soil treated with 2 gallons of 
the solution to 20 feet of row; not much rusted; yield normal. 
Plats 54 and 120. —Seed and spraying treatment, the latter every ten days with Bor¬ 
deaux mixture, the former with hot water; slightly rusted; very similar to the pre¬ 
ceding group. 
Plats 56 and 122. —Seed and soil treatment; hot-water treatment for seed; 2 ounces 
flowers of sulphur and 2 ounces air-slaked lime mixed to 20 feet of row for soil. The 
yield was about up to the average, but no appreciable lessening of the rust could be 
detected. 
Plats 58 and 124. —Seed and soil treatment; hot-water treatment for seed; 2| ounces 
ferrous sulphate to 25 feet of row for soil; normal yield, but no diminution of rust. 
The following plats, as already indicated, were held for spring treatment: 
Plats 60 and 126. —Sprayed with Bordeaux mixture ; the yield was good and the 
rust was considerably less than on the adjoining untreated plats. 
Plats 62 and 128. —Sprayed on the same dates as the last 2 plats, with ammoniacal 
carbonate of copper solution; very similar to the preceding group in all respects. 
Plats 64 and 130. —Sprayed at the same time as 62 and 128, with potassium sulphide 
solution, 2 ounces to 3 gallons of water; this spraying was deleterious and decreased 
the yield noticeably; it had little effect in preventing rust. 
In the following table is shown the yield of straw and grain for each 
plat and its duplicate:
