8 BULLETIN 88, U. S. DEPARTMENT OF AGRICULTURE. 
First application.—As soon as the petals have fallen, spray the 
trees with arsenate of lead, using the poison at the rate of 6 pounds” 
to 200 gallons of water. Direct the spray straight into the calyx 
cups, for which purpose an elbow or crook should be used on the end } 
of the spray rods. In spraying high trees a tower is indispensable, 
as shown in figure 2. 
Second application.—About two weeks after the falling of the petals’ 
spray with arsenate of lead at the rate of 8 pounds to 200 gallons of 
water. Make an effort to apply this spray before the calyx lobes are 
more than three-fourths closed, which may be determined by careful 
examination in the orchard. (See fig. 3.) Direct this spray, also, as 
much as possible straight into the calyx cups, and at the same time 
take care to coat the leaves and fruit. 
Third. application.—Eight or nine weeks after the falling of the 
petals spray again with arsenate of lead at the rate of 8 pounds to 200 
gallons of water. In this treatment cover the foliage and fruit as 
uniformly as possible with the poison. 
Subsequent applications —The three applications specified, if thor- 
oughly made, should effectively control the codling moth, as shown 
by the results of experiments herewith reported. If these applica- 
tions have not been thoroughly made, and it is seen that the codling 
moth will do considerable injury, additional applications will doubt- 
less be desirable to check the insect as much as possible. Thorough } 
work, especially in applying the first and second applications, should 
largely obviate the necessity for more than three treatments.
