110 REPORT OF THE COMMISSIONER OF AGRICULTURE. 
\ 
“Tn noinstance did I find two Codling Moth larve in the same fruit, 
but several times found it and Curculio larvee together, in which case 
I counted it to both; several times found as many as six Cureulio 
larvee in same fruit. 
‘*T had also planned a much more extensive set of experiments for 
the old orchard, but it set no fruit at all. 
‘“‘T sprayed two orchards for farmers who were interested, one 
living 6 and the other 9 miles out in the country. These were so far 
out that close observations were impossible. I went to Mr. F. P. 
Dill’s place, 9 miles out, on Saturday, May 14... The trees were but 
a few days past bloom and in fairly healthy condition. The Canker- 
worms which have infested this orchard for some years had already 
made their appearance in such numbers that they would soon have 
destroyed the foliage on fully one-half the trees. The orchard is an 
old one, part of the trees having been planted by one of the first 
settlers, and some of them are 30 to 40 feet high and 40 to 50 feet 
through the branches at the widest part. It contained about 250 
trees. The spray apparatus used was the Nixon’s ‘Little Giant, with 
his small-size pump fitted with but one spray nozzle. 
“‘On the first half of the orchard we used Paris green and on the 
other London purple, both mixed i pound to 75 gallons of water. 
“Three men did the work, which allowed achange at the pump at 
frequent intervals, as the force required with this size pump to spray 
such large trees was more than one man could stand for any length 
of time. However, by changing about, the work was readily ac- 
complished. The whole time occupied was a little over eight hours. 
Six pounds poison was used and 450 gallons of water. 
‘‘ Results. Here, as at the university, the fruit nearly all blighted. 
“The Canker-worms were destroyed, and what little fruit ma- 
tured was quite free from Codling Moth. 
‘‘The other orchard sprayed was for A. J. Gantz, 6 miles out in the 
country. 
‘‘ His is an old orchard containing about 200 trees; used London 
purple and Paris green as before. 
“This orchard was fairly sprinkled with Canker-worms, both 
pometaria and vernata being present. 
“‘The worms were destroyed and the trees made a good healthy 
season’s growth, better than for years. The fruit was just setting at 
time of application and the trees matured about one-half crop, 
not blighting so badly as the others. I examined these several times 
and found only from 20 to 30 per cent. affected by Coding Moth, 
and the farmer said it was some of the best fruit he had grown for 
years. ‘ 
“The largest orchard in the county is on an adjoining farm 
owned by Mr. Coe, and his fruit that did mature was almost worth- 
less from effect of Codling Moth.” 
Mr. Alwood sent materia! to five different prominent growers 
throughout the State of Ohio, asking them to make experiments, but 
only one furnished a detailed report. 
Mr. Alwood vouches for Mr. Cushman’s reliability and states that 
he is a member of the American Pomological Society, American 
Horticultural Society, and Ohio Horticultural Society, and his report 
is so interesting that we publish it in full: 
EUCLID, On10, November 14, 1887. 
Sir : It gives me pleasure to make the following report concerning the use of 
Paris green and London purple for the Codling-moth worm in apples,
