Remedies. — Deciduous fruit trees : When the tree is dormant, 

 spray with Nos. 11 or 12, as directed ; or No. 13 — five pomids 

 to six gallons of water. In Spring or Summer, when the young 

 are hatched, spray thoroughly with Nos. 5 or 7. (No. 4 may be 

 used and prove very effective, but the solution containing sul- 

 phur is preferable, as it destroys the black smut.) For citrus 

 trees : (see No. 48), spray, etc., as directed in No. 49, and also 

 as directed for olive trees. For olive trees : Use same as for 

 citrus trees ; or No. 9, with one gallon of water added to every 

 gallon of the solution. Example — To tliirty gallons of No. 9, 

 add thirtv gallons of Avater — sixtv in all.
