WICKSON PLANS
SOUTHERN WORK
Branch Experiment Station to
Continue Studies of Citrus
Fruit and Walnuts

BERKELEY, June 1.-THE outline
of work for the fiscal year beginning
July l at the Southern pathological
laboratory and branch experiment sta
tion. has been announced by the uni
versity authorities.
The work has been outlined by Prof.
E. ]. Wickson, dean of the agricultural
department, as follows:
la AT the plant disease laboratory at
Whittier the work for the demonstration Of
the success of varieties of English walnut i'm
mune TO the bacterial blight as Gf
escaping that disease will continue. Results
already attained xvarrapt increased confidence In
this recourse. Systematic observation upon the
behavior of trees found prohtably resistant, by
a survey Of the large area of seedlings in
bearing. is to be continued and propagation for
distribution of such resistants is to be under
taken more freely.
tbl Correlated with this work is the trial
Of large number Of seedlings of different
species and varieties to determine relative suit
ability as root stocks upon which TO graft or
rieties, and this will be continued during the
coming year.
tory studies of the disease itself and its effects
also of related problems of vegetable physiology
and pathology and of conditions affecting these
(d) The same advantage will extend to the
continuation and extension of the work upon
diseases of citrus trees This will require
mining the character and behavior of involved
parasitic organisms and their relation TO vari-
Gus host plants.
(e) The better equipment of the laboratory
will also facilitate the increase of work for
the protection Of important commercial yege-
tables, like the tomato, celery, etc, which is
popularly demanded because OF widely recog-
nized demonstration of the value of prescrip-
tions of remedies and treatments already made.
(f) In its chronological phase the laboratory
at Whittier will proceed with original work
upon life histories of the most important scale
insects infesting citrus trees. 1t will undertake
special work with the mealy bug. which is
menace in certain localities, and with the melon
aph1s. which is causing great losses in Coachelle
and Imperial valley cantaloupe industries.
2-tal At the citrus experiment station at
Riverside studies and experiments of soil fer
tilization with special reference to citrus trees
will continue Systematically.
(b) Closer pomological studies will he under
taken of the several citrus belt varieties, with
view Of improvement and overcoming recog-
nized defects in character and behavior. To this
end increased work will be done in selection
and in propagation for close comparison upon
tc) The expert staf of the Riverside station
will be increased during the coming year in the
line of advanced pomological studies.
S-The work in the Imperial valley and sim
liar adjacent regions, consisting of investiga-
tions on the conditions and problems attending
the culture OF crops and the solutions OF various
difficulties which have arisen in said region
account of unique natural conditions obtaining
in that portion Of the state and provided for by
the last legislature. will be energetically en-
tered upon during the coming year.
