WIRE-WORMS 285 



Traps of Carrot, Mangold- Wurzel, Potato and 

 Swede Turnip have been found of great service in 

 getting rid of wire-worms. Place pieces of these roots, 

 or of rape cake, close to the infested plants. These 

 Carrot, Mangold-Wurzel, Potato or rape-cake traps 

 should be placed close to the centre of the plant or 

 between the rows, about four or five inches deep, this 

 including the bait. Examine every morning for a 

 time, and then once or twice a week, taking out and 

 destroying the wire- worms on each occasion. The 

 traps should be continued during the spring and 

 summer and until winter on badly infested land, and 

 remember that the traps will be likely to be more 

 attractive when vegetation is bursting forth into 

 renewed life in spring. As without guides it is 

 difficult to find the traps, white sticks or wooden 

 skewers with points and thick heads should be used 

 in the case of Carrot, Mangold-Wurzel, Potato and 

 Swede Turnip traps. The sticks show where they are, 

 and enable them to be pulled easily from the soil. In 

 the case of rape-cake traps galvanised iron skewers 

 should be used, and these baits, all points considered, 

 are the best for wire-worms.
