Sonie very promising types have been selected and are bénng planted in 
isolated ee throughout Riverside County in order that the necessity 
to use bags on the seed stalks ray be obviated. Each plant of the re- 
Sistant strains is separately inoculated with curly-top in order that 
there may be assurance that all are relatively immune. 
In the Baker-Charltéan (Florida and Georgia) sweet=-potato weevil 
Peeject conditions have been unusually favorable for securing an early 
spring cleanup and the work has been completed in record tine, A matere 
ial advance in cooperation shown has been noted during the present win- 
ter and it is believed that much greater progress will be made during 
the coming year than heretofore. Anout 1,250,000 draws from weevil-free 
bed potatoes will be secured from the varieties which have “been bedded, 
and conditions appear unusually favorable for early and abundant product- 
ion. Within a short time the seasonal work on wild food plant eradica- 
tion will be resumed at Daytona, Fla., where a series of experizents, 
with special reference to the seaside morning-glory, is under way. Many 
of these appear very promising,
