3602 REPORT OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
ENTIRE TREES. 
May 22. Trees are more retarded than above. 
June 7. Six trees are declining. Four trees are in fair condition. 
July 5. All trees are in very poor condition. Tops are dead. Few sprouts 
show on trunks. 
Lot 6. Dippep TEN MINUTES. 
TOPS ONLY. 
May 22. All trees are much retarded. 
June 7. Tops practically killed. More or less sprouting on trunks. 
July 5. Tops of trees consist entirely of dead stubs. Sprouting on trunks 
below branches. 
ROOTS ONLY. 
May 22. All trees in leaf. 
June 7. Leaves in full number but are small. 
July 5. Tops of trees are small and growth is poor. No apparent injuries 
to branches. 
ENTIRE TREES, 
May 22. Six trees much retarded and showing considerable injuries. 
June 7. Tops dead. Much sprouting on sides of trunks. 
July 5. Trees are nearly dead. Sprouts on sides of trunks are making + 
feeble growth. 
Summary of results — The trees in lots I to II inclusive showed 
very little difference in their conditions as a result of the treatment. 
The trees generally made a satisfactory growth. Plants immersed 
for three or more minutes usually sustained severe injuries. Trees 
with their tops only immersed had many buds and some of the wood 
killed. Injuries to the lower branches were followed by consider- 
able sprouting on the trunks below the areas treated. The effects of 
immersion of plum roots in the sulphur wash for the longer time 
periods were somewhat variable, but as a rule such treatment was 
followed by a poor growth, resulting in many instances in the death 
of the trees. No injuries were apparent among the checks, of which 
there were thirty. 
EXPERIMENT XII. 
FITZGERALD PEACHES DIPPED IN SULPHUR WASH FOR DIFFERENT 
TIME PERIODS. 
The details of this experiment are the same as described for ex- 
periment IX. For the treatment, 300 3-year-old Fitzgerald peaches, 
taken from cold storage, were used. The details of the dipping 
operations are as described in preceding experiments.
