AN SUL FORMALDEHYDE DUST 
For Controlling “Damping Off” of Flower and Vege¬ 
table Seedlings; also for dusting Potatoes 
and any grain seeds before planting 
Treatment is safe, economical and easy to apply. No steam 
sterilization or seed treatment is necessary 
Ansul Formaldehyde Dust is a seed and soil treating com¬ 
pound which controls seed-borne diseases and when applied to the 
soil controls “damping off” and other root rots of vegetable and 
floral seedlings. The sterilization of soil and seed with Formalde¬ 
hyde is not new; in fact, it is one of the oldest disinfectants known. 
However, it is not easy to apply in the liquid form and, too, the 
method of treatment does not fit into the grower’s program. The 
wetting of the soil and the long wait are undesirable. The Ansul 
Formaldehyde Dust treatment, the mixing of the soil and the 
planting of the seed are all one operation. It is also excellent for 
dusting potatoes and any grain seeds before planting to help con¬ 
trol fungus diseases.
