Kainit, or other potash salt, has been recommended by Dr. Smith, of 

 the N. J. Agricultural Experiment Station, as an insecticide of value 

 against wireworms in the soil, and also as a substance that will destroy 

 the pear-midge after it has buried for pupation. If effective against these 

 insects, a heavy dressing of it would be of value in the greenhouse. Not 

 only would it destroy the mites in the soil, but it would also stimulate the 

 carnations to more vigorous growth.
