KOLOFOG. Highly effective sulfur spray 
for use on apples and peaches, replacing 
lime-sulfur solution in all sprays following 
dormant or delayed dormant. Because of 
its great adhesiveness it makes an excellent 
carrier for Arsenate of Lead and is especially 
recommended for use in the calyx and first- 
cover spray. Will not russet fruit or burn 
foliage. In later sprays, where the excellent 
sticking qualities of Kolofog may be ob¬ 
jectionable, we recommend the use of

form of Kolofog containing more free sulfur 
and less colloidal sulfur. Because of the

following the first- or second-cover spray.
