Pests controlled

dies than 
spraying 
Pear blight (fire blight of 
pear and apple). 
Western tomato blight. 
Potato scab. 
Smut of wheat and oats. 
Prune out every sign of blight, cutting well below the disease. 
Swab every cut with corrosive sublimate (1 to 1,000 of 
water). Clean the tool often with carbolic acid, or you will 
spread the blight with each cut. 
Set out strong plants close together, or plant the seed thickly 
in the rows. Give best of care, shade and plenty of water. 
You will probably lessen the blight. 
Soak seed for two hours in formalin (1 lb. to 30 gallons of 
water), then cut and plant. Do not plant in soil where 
scabby potatoes were grown. 
Spray seed thoroughly with formalin (1 lb. to 45 gallons of 
water; cover and let lie in a pile two hours; dry and plant 
with a clean seeder.
