day, and in warm weather they develop in about three days, but they take 

 longer in cooler weather. The young worms are not very resistant to 

 unfavourable weather conditions, and soil treatment aims at destroying the 

 worms while still young and tender ; the eggs have a resistant coating, and 

 the mature females are safely protected inside the root. Drying out of the 

 soil, or flooding the soil, is usually fatal to thfem in a comparatively short 

 time. Soil kept free from vegetation for about two years usually results in 

 the worms being killed out. 



Potatoes infested with Eel worms. 



Tubers and roots used as seed should be free from scab, as the scab areas 

 may contain the worms. 



In a small garden, two or three treatments of the soil, at intervals of about 

 eight or ten days, with formalin 1 part, in water 50 parts, applied at the rate 

 of 2 gallons to a square yard, should be used. Tt is of advantage to cover 

 the soil with wet sacking after each application.
