26 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1933 
There were sprayed, during this application, 4,460,202 trees on 13,867 premises. 
The material used amounted to 23,520 gallons of molasses and 1,176 gallons of 
nicotine sulphate. Weather conditions as regards rainfall were ideal throughout 
and following the application. 
The second application was started May 22 and was practically completed by 
June 21. A number of young trees in isolated locations were omitted in the 
second application, leaving only 3,875,075 trees on 13,040 premises which were 
sprayed. In the second application, 21,239 gallons of molasses and 1,060 gallons 
of nicotine sulphate were used. 
Because of the abnormally dry conditions prevailing during the spring and 
early summer of 1933 when the two applications of spray were made, and since 
traps operated throughout the valley after May 1 had given negative results, 
the remaining material was reserved for use in the event that infestations should 
become established in the future. 
Approximately 500 knapsack sprayers were used in applying the poison spray. 
These sprayers were furnished by "the State of Texas and the three counties 
involved. City governments, civic organizations, and individuals assisted in 
the work by furnishing labor, storage space, and miscellaneous supplies. With- 
out the excellent cooperation of the industry as a whole, the 100 percent coverage 
of the producing trees of the quarantined area would have been impossible. 
Even with the assistance rendered by the various organizations, the absentee- 
owned and abandoned groves constituted a most difficult problem to handle, 
and the complete coverage of bearing trees was possible only because of the 
resourcefulness and ingenuity exhibited by the district inspectors. 
Details of the spraying activities are given in table 9.

CERTIFICATION OF FRUIT 
Several million permit tags are required each season to certify the fruit moving 
out of the quarantined area. To avoid difficulties in keeping an accurate check 
on the use of these permit tags, a system of requiring a master permit to accom- 
pany each commercial shipment of six or more packages of fruit was instituted 
at the beginning of the shipping season last fall. These master permits were 
issued by the inspectors upon exhibition of a bill of sale by the trucker covering 
the fruit in the load, upon request of the grove owner making the sale, or to 
cover the movement of fruit from approved packing houses. By this method 
the inspectors were enabled to identify the groves in which all fruit leaving the 
quarantined area originated. These permits were issued when the load was 
ready for shipment regardless of the hour of day or night. Many were issued 
after office hours and on holidays.
