A Wisconsin grower protected 7,000 
plants and secured a splendid crop, while 
unprotected plants nearby would have 
been a complete failure if the maggots 
had not been picked off by hand. Others 
have reported similar success. One re- 
ported having lost only 25 plants out of 
10,000 to 15,000 that he protected with the 
cards, where ordinarily he should have 
lost from 75 to 90 per cent of the crop. 
This method in actual practice has 
proved to be cheap, practical and efficient. 
Its success depends on the timely and 
proper application of the cards. They 
should be applied as soon after trans- 
Planting as convenient and must be 
pressed down firmly about the plant, leav- 
ing no open spaces. Soil should not be 
allowed to collect on top of the disc. 
Remedial 
In reviewing the current economic 
literature as well as in local practice, as 
revealed by our correspondence, I find the 
results attending the use of the materials 
for the control of this pest are as varied 
as the materials themselves. That many

of the treatments recommended are im- 
practical is certain. Of those remaining 
none now in current use seem to give 
uniform satisfaction under all conditions. 
The Carbolic Acid Hmulsion.—While 
giving negative results in our trials, had 
earlier in the season been suggested to 
growers, who in several cases commented 
upon its use most favorably. It is possi- 
ble the solution was too strong; certainly 
more trials are necessary to prove the 
status of this remedy for our conditions. 
It is prepared as follows: 
Crude carbolic acid.................. 1 pint 
Hard SOD .2......-ceecpceeeeeceeeeeeneneees 1 pound 
Water oon... cececncesnceneneceeneeeccccanwece 1 gallon 
Dissolve the soap in the boiling water; 
remove from the fire and add the carbolic 
acid. Agitate briskly for some time to 
form a perfect emulsion. For applica- 
tion use one part of the emulsion to 30 
parts of water. 
In using this solution draw back the 
soil from about the plant, exposing as 
much root surface as practical. Apply 
about half pint of the material to each
