276 MANUAL OF FRUIT DISEASES 
cankers from the larger limbs, and prune out affected limbs 
of smaller size. The methods followed are described under 
another heading (see page 52). In pruning, knock off the 
hanging mummies: Bury the fallen mummies by plowing 
to a depth of several inches; this should be done before the 
blossoms open. The regular pruning operations assist to no 
little degree in the control of the brown-rot. The removal of 
limbs admits sunlight and air, thus allowing the susceptible 
parts to dry off more quickly after rains. 
The fruit should be sprayed. This can be done without 
fear of injury to the foliage by the use of self-boiled lime-sulfur 
of the 8-8-50 formula (see page 438). For curculio, add 2 
pounds of lead arsenate to 50 gallons of the fungicide. Never 
use lime-sulfur solution as a summer spray, even at dilute 
strengths, since a 1 to 300 dilution may seriously burn peach- 
foliage. Spray: (1) about the time the blossoms fall; (2) two 
or three weeks later or about one month after the petals drop; 
(3) about one month before the fruit ripens. 
Limited experiments indicate that lime-sulfur solution 1-40 
may be used safely and effectively before the blossom-buds 
open. This application purposes to prevent bud-infection, and 
is worthy of trial.
