REMEDIAL MEASURES.

CARBOLIC ACID. 
Some seeds were soaked in a 10 per cent solution of carbolic acid 
overnight, were allowed to dry for some time, and were then planted 
in the pots. Fifteen were planted in the cage which contained the 
50 larvae. This cage was broken up in 20 days and examined, with 
the following results: Two seeds were destroyed before germination; 
seven after germination, and six were untouched; three larvae were 
dead. In the check cage three seeds were untouched; most having 
been destroyed just after germination, and one larva was dead. 
The check cages gave even less favorable results, so it seems clear that 
the carbolic acid has little effect as a deterrent. 
CARBOLIC EMULSION. 
Carbolic emulsion was made by using the following ingredients in 
the proportions named : ^ 
Crude carbolic acid gallons . . 5 
Whale-oil soap pounds . . 40 
Water (hot) gallons . . 40 
The seeds treated were soaked in this emulsion overnight. After 
drying ^ in the sun for two hours they were planted. The results of 
the experiments are summarized in the following table:

A glance at the foregoing summary shows that while carbolic acid 
might possibly be of value, it can not at this time be considered a 
practical remedy for wireworms. 
TURPENTINE. 
Seeds were soaked overnight in turpentine and after being allowed 
to dry were planted in the cages containing the wireworms. The 
turpentine had affected the seeds considerably and all of them were 
more or less ''blistered.'' 
' Essig, Pomona Journ. Ent., vol. 2, no. 3, p. 252, 1910. 
2 The seeds were dried in these experiments because, if used under field conditions, they would have to 
be treated in this manner before they could be used in a beet planter. This would be the only practical 
way the emulsion could be applied.
