Don’t try to outguess the smut. Clean or smutty— 
treat your seed with New Improved Ceresan. If the seed is 
smutty, the treatment usually will control the smut and 
increase the yield, too. If the seed is clean, New Improved 
Ceresan will often increase the yield anyway. There’s 
nothing to be gained by guessing; play safe with New 
Improved Ceresan. 
One-Half Ounce Treats a Bushel 
Only one-half ounce of New Improved Ceresan is needed 
to treat a bushel of seed. New Improved Ceresan is quickly 
and easily applied as a dust by means of a rotary seed 
treater or by the shovel method. After treating, the seed 
should be stored in a pile or sacks for 24 hours before 
planting.
