THE MONTHLY BULLETIN. 19 



The gray mold has. however, been found to be fairly abundant this 

 year in several of the other orchards and in most cases could be traced 

 to the inexperienced help we were forced to use last season, in order to 

 get over the groves. The same factors that influence results in brown 

 rot control are found in the treatment of Botrytis. and an early dis- 

 covery and careful cutting out of the infection are absolutely necessary. 



Many infections found on the trunks have been cured, or new bark 

 has started to form without any treatment being given. This has been 

 the case with the inoculations made in one orchard, but where the infec- 

 tion is in the branches it continues to kill out the bark rapidly and 

 soon girdles a limb. One limb, in a tree on which a large area was 

 infected, Avas marked in June, in order to watch the progress of the 

 fungus. The infection was i.solated with a cut half an inch wide made 

 all the wav around, but only half of the area was covered with Bordeaux 

 paste. The treated part, when examined the 18th of July, was all right, 

 but where no treatment was given the fungus had killed out the good 

 bark to the end of the limb. 



One could not well leave a discussion of the brown rot gummosis and 

 the gray fungus gunnuosis without giving Professor Pawcett and 

 Dr. Cook full credit for solving one of our most important problems. To 

 Dr. Cook is due credit for .selecting such a man as Professor Faw«'ett to 

 carry on work of this kind, and then for straining every point in the 

 horticultural law to permit of the appointment of a plant pathologist 

 where no provision was made for this line of investigation. The excel- 

 lence of the work done by Professor F'awcett on gummosis is fully appre- 

 ciated by all state and federal horticulturists, who give it their generous 

 and unstinted praise, and its importance to the citrus grower is recog- 

 nized by all who have had much of this disease to contend with in times 

 past.
