“The past year saw the Bess ets Gr of the second ‘year of eradication tests, 
After checking up the work: of the previous year it-was seen that the weakest — 
part of the campaign was in the cleanup given the fields in the infested. ter=— 
ritory, In the year just past additional caré was given to this phase of the 
work, about °$1,000 being spent. in removing the old vines and leftover pota- 
toes from the fields on which the least progress had been made in the preced-— 
ing year,.- The cost of this operation averaged | about $12. ‘per acre and later 
inspection in the fields cleaned has indicated that the operation was very > 
profitable, The inspectors gave the farmers assistance in disposing of théir 
potatoes early and cleaned and hurned most of the banks themselves, Later | 
the drews grown by the Florida State Plant Board were . distributed. and the re 
mainder of the year given ever to cleaning banks and volunteer plants from the 
old ficlds; Prospects:for a.crop in: the, infested territory are very good. 
The life-history work was completed and progress made in the fumigation tests 
of stored potatoes. Eradication of wild beach morning-glory was tested out 
and considerable additional information gotten on the seasonal history of the 
weevil in both sweet potatoes and wild food plants.
