REPORT OF THE STATE ENTOMOLOGIST I917 IQ 



Plot I was located in the first and second rows on the south side 

 and next to a peach orchard and on the fourth to sixth rows, inclusive, 

 from the west side. Plot 2 was on the third row from the peach 

 orchard and the second and third rows from the west side, the 

 latter being occupied by a young apple orchard. Plot 3 began with 

 the fourth row from the south side and was on the fifth and sixth 

 rows from the west side. There was also a fourth plot which was 

 on the fifth row from the south side and the third and fourth rows 

 from the east side. This last consisted of three Baldwin trees and 

 three greenings. The two check trees were the second and fourth 

 trees from the west side and in the second row from the north. 



The first application was made June 9th. Tiger nozzles were 

 used, three on the tower with a 10 foot extension and two on the 

 eround. The distribution was excellent and the trees were well 

 covered. Thomsen's arsenate of lead was used at the rate of 

 2I pounds to 50 gallons of water and lime sulphur 32° Baume i to 

 40. A pressure was maintained of from 175 to 200 pounds and 

 about 20 gallons of material were applied to each tree. 



The following notes were made at spraying time. Plot i, trees 

 A and E, and plot 2, tree C, had a light bloom. Tree E in plot 2 

 had only about one-fourth of a bloom. The trees in plot 3 were well 

 and heavily loaded with blossoms and those of plot 4, both greenings 

 and Baldwins, showed a good bloom and at the time of spraying about 

 one-third of the blossoms had fallen from the greening trees. 



The second spraying in this orchard was given July gth, the 

 work beginning at 9.40 a. m. but, owing to engine troubles, the 

 spraying was not completed until afternoon. Trees A, C and E 

 of plot 4 and one-half of the other three were nearly completed in 

 the morning. The work was exceptionally thorough. There were 

 two leads of hose, one man standing on the tower and the other 

 working from the ground. There was very little breeze, the foliage 

 was well loaded with the spray and yet there was comparatively 

 little dripping. Ten pounds of Thomsen's orchard brand arsenate 

 of lead was used to 200 gallons and lime sulphur at th3 rate of i 

 to 40. 



Plots 2 and 3 were sprayed later under the supsr/is'oii of 

 Mr Spooner. It was stated that trees C and E of plot 4 were not 

 sprayed from the under side in the pink of the bloom and con- 

 sequently there was perceptibly more scab than on other trees in 

 this plot, although there is a fairly good crop of fruit, and the same 

 is true of the other trees.
