26 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1936 
which Lnfe8tatlOD had been found In previous yean and gave added assurance 
of freedom from Infestation. During the past several years a section-by-section 
survey to locate unlisted palms had been carried on to guard against the | 
bility thai such trees might be missed by the Inspectors and thus enable the 
scale to carry over. This scouting for unlisted palms was completed. Dar- 
ing the past several years Intensive Inspections at appropriate Intervals were 
made i«> detect Infestations as promptly as possible bo as to prevent lnf< 
from serving as centers of spread. As circumstances warranted, the In- 
tervals between these Inspections were Increased, the program was broadened 
by Intensive leaf-base Inspections and finally by the unlisted-palm scouting, and 
the completion of these activities, together with the passage of a substantia] 
period without finding any Infestation, leads to the decision that this completes 
the Federal-State date scale eradication project 
COACHELLA VALLEY 
During the year 33,434 palm Inspections were made from the ground only. 
3,007 palm Inspections were made from ground and ladders, and ( a4.", offshoots 
were certified for movement. Leaf bases were removed from 81 previously In- 
fested palms, and 59 valueless palms were dug out and destroyed. A total <>f 
•M 1 , sections were scouted for unlisted palms and 114 properties in this valley 
rechecked. This Is the fourth consecutive year that no parlatoria date scale has 
been found in the Coachella Valley. 
IMPERIAL VALLEY 
In the Imperial Valley intensive inspection was continued in the Reed Garden, 
the only planting in which scale has been found since the fiscal year 1933. 
The final inspection of the garden was made in April if>:*G. No scale has been 
found since February 1934. 
At the close of the fiscal year 1935 a considerable number of properties in the 
Imperial Valley were dropped from the Inspection lists, inspection was con- 
tinued in the remainder. All plantings too bushy for careful inspection were 
pruned. Leaf bases were inspected and removed from all previously infested 
palms where necessary. Infested properties were checked for volunteer palms. 
A final scouting and inspection of palms other than date in the infested area was 
made. 
A total of 11,857 palm inspections were made. 463 palms were pruned to faeili- 
DSpection, and leaf h;ises were removed from 59 previously Infested palms. 
ARIZONA 
In the vicinity of Yuma 3,596 palm inspections were made, completing the 
Federal-State project in Arizona. 
A summary of date-scale activities is given in table 10,
