2. Powdered White Hellebore: to be used like the ground 

 tobacco as a preventive, but also as a killing agent in the form of a 

 decoction of two ounces of the jwwder steeped in one gallon of hot 

 water. Applications of the decoction at the rate of three to four 

 ounces per plant whenever maggots were actually present. 



3. Carbolic Acid Emiddon: make into an emulsion one pound 

 hard or one quart of soft soap, one gallon of hot water and one pint 

 •of carbolic acid. ])ilute for use with thirty parts of water. This 

 as a killing agent and was to be applied wliencvcr maggots were 

 present on the plants. 



4. Scalecide: a killing agent, to be used like the carbolic acid 

 «niuiJsion at the rate of one to twenty-five. This is a petroleum 

 preparation that had never been used against underground insects, 

 iind it was desired to learn of its effect on them and on the plants

5. Kero'sene and Sand: a large cupful of kerosene to a pail of 

 flry sand, well mixed and applied on the surface around the base of 

 ithe plants to be protected. It is a repellant and should be in 

 position to prevent the fly from laying eggs.

 jtommla of one-half pound soap, one gallon of water, two gallons of 

 Eierosene. Dilute for use with twelve parts of water and apply as

7. Exposure: remove the soil from the base of cabbage plants as 

 :3oon as they are well rooted and allow a long stem to be exposed 

 for a week so as to toughen it. Then hill up around the plant and 

 jrdck well. The suggestion is that if eggs are laid on the toughened 

 .•stem the young larva? will not be able to penetrate it and will die. 

 Must be done before any flies are in the field. 



8- Tar paipcr disls: round disks so cut as to fit around the stem 

 •of a i!abbago plant at the surface of the ground and intended to pre- 

 A'cnt the flies from getting at the place where the eggs should be 

 3aid to give the resulting larvie a fail' chance for life.
