tive against the "peach-leaf curl" and the "brown rot,"^ 

 also for the "apple scab" and "pear scab" and other fun- 

 gous diseases of fruits. 



These fruit pests cannot all be reached at the same 

 time with any other of the numerous methods of treat- 

 ment which are sometimes substituted for the Lime-Sul- 

 fur for controlling the San Jose scale. No other insec- 

 titude now known can equal in range of usefulness and 

 in economy a single thorough application of Lime-Sulfur 

 wash to fruit trees just before the buds start in the 

 Spring. 



Manifestly these important considerations in favor of 

 Lime-Sulfur far outweigh all contrary ones based upon 

 the inconvenience in its preparation and the disagreeable- 

 ness of handling and applying it. To obviate the objec- 

 tions to the preparation of the wash any one who desires 

 may now buy it in a concentrated solution ready to dilute 

 directly with water for spraying. It is sold by several 

 of the manufacturers of insecticides whose addresses are 

 given in the Appendix on page 21-22. This might be partic- 

 ularly desirable for the man who needs but little of the 

 wash. The commercial article has shown up favorably 

 in experimental tests but apparently has no superiority 

 in effect over the home-made article which, of course, 

 costs somewhat less. 



Determination of Specimens and Special Advice. — 

 Specimens suspected of being San Jose scale, and any 

 other insects attacking fruits, trees, garden and field 

 crops, etc., may be submitted to the Entomologist, Ala- 

 bama Experiment Station, Auburn, Ala., for determina- 

 tion. They should be mailed in a tight, strong box bear- 

 ing plainly on the outside the name and address of the 

 sender and separate from the letter of advice which 

 should describe as fully as possible the nature and extent 

 of the injury which the insect seems to be doing. The 

 Entomologist will gladly and freely give any suggestions 

 possible'for combating insect pests thus brought to his at- 

 tention.
