Unfortunately the ''check" trees were given the petal-fall 
application and are therefore not recorded. 
At Nemaha (table 2), a power spray of 12-gallons-to-the- 
minute capacity, similar to fig. 23, was used. The petal-fall spray 
was applied with Bordeaux nozzles under a pressure of 250 pounds. 
All other appHcations were made with mist nozzles. It is un- 
fortunate that we have no check with which to compare the sprayed 
plats. It is interesting to note that a spray applied 22 days after 
the regular second-brood spray reduced worm injury 6.18 per cent. 
Nearly 50 per cent of the larvae entered at the calyx. The trees 
here were so tall that it was difficult to reach the tops, and no doubt 
a larger percentage of first-brood larvae escaped than would have 
been the case with smaller trees. This orchard had never been 
sprayed before.

At Brownville (table 3), a barrel pump similar to fig. 18 with 
one mist nozzle was used for the calyx application. For the next 
application a one-man power sprayer of 3- to 4-gallons-per-minute
