The treatment with formaldehyde is cheap, convenient, and 

 effective. When grain containing smutted kernels is to be used 

 for seed, it should, after being cleaned, be dipped in a solution 

 made by diluting 1 pint of 40-per-cent formaldehyde in 45 gal- 

 lons of water. A tub or half barrel is best for dipping, about a 

 half bushel being immersed at a time. After skimming off 

 smutted kernels on the surface, the immersed grain should be 

 stirred to release other smutted kernels imprisoned there. When 

 no smutted kernels can be secured, the grain may be removed and 

 dried. A wire screen basket made to fit within a half barrel or 

 tub facilitates the work, as it enables one easilv to remove the 

 grain from the liquid. A large piece of burlap placed over the 

 tub may be used in the same way. 



If the grain contains no smutted kernels it may be treated by 

 sprinkling as is recommended for oats. Grain from fields con- 

 taining no smut, that has become contaminated at thrashing time 

 or in some other way, may be treated in this manner. 



Loose smut cannot be controlled by this treatment; and, if 

 severe, the best method of avoiding it is to secure seed from smut- 

 free fields. 



TOMATO blight 



This disease caused by Septoria, lycopersici has been severe the 

 past year and may be destructive in the future. The disease 

 can be controlled by spraying with bordeaux as for potatoes. 

 Several applications should be made. With the present methods 

 of growing the crop it is rather difficult, if not impossible, to use 

 power sprayers without doing more injury than good. WTiere a 

 hand sprayer can be used the spraying can be done with satisfac- 

 tory results. 



bean anthracnose 



There are three methods by means of which this disease may 

 be controlled, namely, spraying with home-made bordeaux, prac- 

 ticable only in gardens or in seed plots ; using resistant varieties 

 when these can be secured; and selecting seed from clean pods, 

 the most promising way for most varieties and conditions. 



To carry out the w^ork according to the latter plan it is neces- 

 sary to select carefully, by examining every pod, a sufficient 

 number of clean pods to secure enough seed for planting a seed
