STERILIZING LETTUCE SOIL. 



Will you give me some information 

 about sterilizing a lettuce house in 

 which the soil is infected with rosette? 

 What is the best means of sterilizing? 

 If steam is used for the purpose, what 

 size of pipes, sixty feet long, would be 

 best, if connected with a 15-horsepower 

 boiler, and how close together should 

 the pipes be placed? What do you think 

 of formaldehyde for sterilizing? 



W. E. M.— Kan. 



There is some doubt as to just what 

 trouble is referred to as rosette of let- 

 tuce plants. Sometimes a resetted ap- 

 pearance is caused by plant lice and 

 similar insects, which can be held in 

 check by the use of nicotine solution 

 or tobacco smoke. When the trouble" 

 is due, however, to certain other insects 

 or fungi, such as cause the damping 

 off of the plants, stem-rot, etc., the ster- 

 ilizing of the soil will be helpful. Live 

 steam answers better than formalde- 

 hyde. 



When much of this work is to be 

 done, or if the soil is on benches, the 

 cheapest way, so far as the outfit is 

 concerned, is to build a sterilizing box. 

 This may be of any convenient size, 

 say 6x20 feet and eighteen inches deep, 

 with a tight cover. The steam pipes 

 should be 1-inch, with a -fV-inch hole 

 every two feet, alternating on oppo- 

 site sides. The pipes should be placed 

 two feet apart, and the holes should be 

 80 arranged that the jets will be be- 

 tween those in the adjacent pipe. If 

 a pipe is placed one foot from each 

 side, with a third pipe in the middle 

 of the box, all of the soil in a box six 

 feet wide will be sterilized. The pipes 

 should be at the bottom of the box and 

 the soil should be twelve to fifteen 

 inches in depth. The length of time 

 required will depend to some extent on 

 the steam pressure, two to three liours 

 being desirable for ten pounds of pres- 

 sure. 



For sterilizing the soil in solid beds, 

 the pipes, after being drilled as already 

 suggested, should be placed in trenches 

 about ten inches below the surface and 

 two feet apart, and after the soil has 

 been replaced the bed should be cov- 

 ered with canvas. If the beds are more 

 than fifty feet long it will be well to 

 use IVi-inch pipe, and unless twenty- 

 five pounds of steam can be given 100 

 feet will be about a maximum length 

 for that size. The steam should be 

 kept on for two hours after the sur- 

 face at the farther end of the house 

 has become warm. 



Arranged in this way, the pipes can 

 be quickly taken up and transferred to 

 other beds. The thorough sterilization 

 of the soil with steam will not only de- 

 stroy all insects and fungi, as well as 

 their eggs and spores, but will also pre- 

 vent the germination of grass and weed 

 seeds. T.
