Carbolic Acid Emulsion. 



This is perhaps the most effective of all the destructive agents, 

 l)nt its value also depends upon timely, frequent and thoroagh 

 applications. It has failed in some hands, chiefly because the 

 \\ork was not begun early enough. The method of making the 

 emulsion is as follows : Dissolve one pound of soap in one gallon 

 of boiling water; to this add one pint of crude carbolic acid and 

 churn thoroughly with a pump until a good, creamy emulsion is 

 olitained. This emulsion, properly made, will remain stable for 

 several days. For use, dilute one part of the emulsion with thirty 

 ])arts of water and apply thoroughly around the plants, from four 

 to six fluid ounces to each. The object is to get it down to the 

 roots and into actual contact with the maggots feeding upon them. 

 Tlie application should be begam as soon as the presence of the 

 nuiggots is noted, or, better still, as soon as the eggs are observed 

 on the plants. Make the first two applications four or five days 

 apart, and later once a week for a month. If the work is 

 thoroughly done and begun early enough, it should destroy the 

 young maggots as they emerge and before they get a chance ^to 

 protect themselves within the plant tissue. Well-grown maggots 

 are quite resistant to the emulsion. This material can also be 

 used against the maggots on radishes and onions by making 

 thorough applications along the rows. 



Hellebore Decoction. 



This has been very successfully used in Canada and some other 

 localities, but has not given, on the whole, such good results as the 

 carbolic acid emulsion in ^ew Jersey. It is made by steeping 

 two ounces of the powdered hellebore in a quart or two of boiling 

 water for half an hour, stirring occasionally so as to help the ex- 

 traction of the poison, and then diluting so as to make one gallon 

 of liquid. Apply in the same way and under the same conditions 

 as recommended for the carbolic acid emulsion. The decoction may 

 be made at any time and may be kept for use as needed in tight jars 

 or bottles. It will keep in tubs or barrels for two or three weeks, 

 or even longer, in the concentrated form, but should always be 

 r^tirred up before using. The sediment or extracted powder may
