4 BULLETIN 88, U. §&. ee OF AGRICULTURE. 
Tt will be noted from Table I that the amount of spray used in 
all applications was large, and probably considerably in excess of 
that used by the average fruit grower in the valley. The amount 
of spray appled immediately following the falling of the petals 
(April 24-25) exceeded somewhat the amount given in any subsequent 
application. It will be noted also that Bordeaux nozzles were used 
at this time, whereas in subsequent treatments the so-called eddy 
chamber or Vermorel type of nozzle was used, producing a fine cone-~ 
shaped spray. 
In Table II are shown the number and percentage of sound fruit 
from each of five trees of each plat, as well as the total number and 
total percentage of sound and wormy fruit for the five trees of the 
respective plats.

It will be seen that Plat I, which received a total of three applica- 
tions of an arsenate of lead spray, gave 95.13 per cent sound fruit. 
Plat IJ, with four applications, yielded a somewhat higher quantity 
of sound fruit, namely, 98.72 per cent; while from Plat III, which 
received five spray applications, 99.39 per cent of the fruit for the 
season was sound. Plat IV, which was not sprayed during the 
season, shows only 40.77 per cent of the fruit free from codling moth 
injury. In determining these results, examinations were made as 
‘to worminess of all the apples produced on the five count trees 
‘throughout the season; that is, the fruit which fell, the fruit which 
was picked from the trees in thinning, and that picked at harvest time.
