74, REPORT OF THE BOTANICAL DEPARTMENT OF THE ° 
DATES OF SPRAYING, ETC. 
At Geneva: Series I— The rows of this series, 1, 4, 7, 10 and 
13 were sprayed three times with bordeaux mixture — July 9, 
August 10 and 30. At the time of the first spraying the plants 
were 12 to 15 inches high. Bugs were numerous but had not 
yet done material damage. Paris green was applied with the 
bordeaux at the rate of one pound to fifty gallons. After this 
there was no further trouble with bugs so the second and third 
sprayings were made with bordeaux alone. 
Series II.— This series consisted of rows 2, 5, 8, 11 and 14. The 
plants were sprayed five times with bordeaux mixture — July 6, 
20, August 6, 20 and 21. Following the fourth spraying on 
August 20 there came a heavy shower (3.10 inches) before the 
bordeaux was dry and washed it off to such an extent that it 
was considered necessary to repeat the spraying the next day. 
After August 21 the weather was so dry and hot that the blight 
made no progress and further spraying was thought to be un- 
necessary. 
At the time of the first spraying the plants were Io to 14 inches 
high. It was the intention to begin somewhat earlier than this, 
but circumstances prevented. Subsequent events indicate that 
no loss resulted from the delay. “Bugs” were hatching in 
considerable numbers. A few were about half grown but the 
majority were just hatched. Paris green, which was used with 
the bordeaux in the first spraying at the rate of 8 ounces to 50 
gallons, seemed to kill the “bugs” satisfactorily, but it was 
necessary to use poison a second time in the second spraying; 
whereas, on Series I and III treated July 9 with double this 
quantity of paris green one application was sufficient. 
Series III.— Series II] consisted of rows 3, 6, 9, 12 and 15. No - 
bordeaux mixture was used on this series. One application 
of paris green in lime water (one pound paris green, two pounds 
lime and fifty gallons water) applied July 9 was sufficient to 
keep the plants free from “bugs” during the entire season. 
At Riverhead: Serics I.— This series consisted of five rows, Nos. 
I, 4, 7, 10 and 13. They were sprayed with bordeaux mixture 
three times (June 12, 18 and August 6) and treated with paris 
green in lime water twice besides (June 26 and July 12). Paris 
green was also used with the -bordeaux in the first spraying. 
Series IJ.— This series consisted of five rows, Nos. 2, 5, 8, II 
and 14. They were sprayed with bordeaux mixture five times
