THE MONTHLY BULLETIN, 



orchard companies who are able to get the benefits of a much reduced 

 price. Until within the last few years the owner of a small orchard 

 was not thus benefited unless the association to which he belonged or 

 the county bought his materials. A cooperative company in the southern 

 part of the State composed of the citrus growers themselves and known 

 as the Fruit Growers' Supply Company, now gives its members the 

 advantage of the prices obtained l)y making large purchases. 



BLOCK FUMIGATION. 



The spread of scale insects in citrus orchards is very rapid and under 

 ordinary methods of fumigation, where only part of a district is treated 

 each year, there is always a source of re-infestation from the trees which 

 have not been fumigated for from one to several years. To eliminate 

 this -condition it is exceedingly desirable to fumigate large blocks or 

 I racts of orchards the same year and thus place each upon the same 

 basis. ' This is known as block fumigation and should be encouraged in 

 every possible way, as it has great advantages over the usual haphazard 

 i'umigation of a district.
