144 HOP. — MANGOLDS. 



For Wireworm in Turnips, it has been found to succeed well 

 to mix sand with just enough paraffin to moisten it slightly — 

 not enough to clog, but still to run in the hand — and to 

 sprinkle this very lightly over the roots by hand. Ashes or 

 dry earth would answer as well as sand. It was found in the 

 Stoke Edith experiments that the Hop-shoots came up without 

 the slightest injury through a dressing of a bushel of dry 

 material sprinkled with a quart of paraffin ; and as the Wire- 

 worms usually feed near the surface, the smell, or the paraffin 

 in dilute state driven down by the rain, would probably soon 

 tell on them. 



Mr. Whitehead mentions in his Eeport previously quoted 

 that, " opening a trench in the autumn after the poles are 

 down, and forming a ring close round the plant-centres, and 

 putting in earth, ashes or sawdust, saturated with paraffin oil, 

 is an excellent plan in the case of plantations that are badly 

 infested" {taking care not to put too much oil, lest it should 

 kill the roots). Likewise that "planters who suspect the 

 presence of Wireworms very frequently set a row of Potatoes 

 between the rows of Hop-plants, in order to draw the Wire- 

 worms from the young Hop-plants." And further, that 

 "dressings of Eape-dust dug in round infested plants will 

 also draw the Wireworms, relieving them for a time, but also 

 tending to collect the Wireworms round or near the plant- 

 centres."
