workers. The woodwork of the seed- 

 beds should be thoroughly drenched 

 with either hot water, a solution of 

 formaldehyde (1 pound of formalde- 

 hyde in 20 gallons of water), Bordeaux 

 mixture, or strong lime-sulfur mixed 

 with whitewash. If the old soil is 

 used, or If there is any reason to sus- 

 pect that new soil is infected, it should 

 be sterilized with steam or formalde- 

 hyde. 



Soil Sterilization is usually used in 

 seed-beds, cold-frames and green- 

 houses, but is sometimes used on soil 

 in the open. The most common meth- 

 ods are the use of formaldehyde and 

 of steam. 



The soil to be treated should be 

 loose and moist. Formaldehyde solu- 

 tion (4 pounds of formaldehyde to 50 

 gallons of water) should be applied 

 at the rate of 1 gallon to each square 

 foot of soil surface. In case the soil 

 is very loose it may be necessary to 

 make the application slowly over sev- 

 eral hours, otherwise the liquid will 

 run through very quickly and be lost. 

 The soil should not be stirred during 

 treatment. Immediately after treat- 

 ment the soil should be covered with 

 burlap, old carpet, fertilizer bags or 

 paper for two days. It should then 

 be aired for ten days or two weeks, 

 and during this time should be stirred 

 thoroughly three or four times. If 

 this is not done the seed may not 

 germinate well. 



The most common method for steam 

 sterilization is known as the inverted- 

 pan method. The pans can be made of 

 No. 22 galvanized sheet iron or pine 

 tar lumber. For out-of-door work they 

 should be made about 6x10 feet. They 

 are attached to a boiler of 15 horse- 

 power or more by means of a common 

 1-inch garden hose which connects 

 with a nipple in the center of the pan. 

 The edges of the pan should be pushed 

 down into the loose soil and weighted. 

 The steam should then be turned on 

 and the temperature held at 200° to 

 250° F. for about one hour In order to 

 get the best results. 



This treatment cannot be used sat-
