to spray up to the beginning of March, so that the second brood of moths 

 is destroyed. 



In many orchards this season the woolly aphis has been vmusually preva- 

 lent on the apple trees, being caused by the moist state of the ground in 

 the early spring. It is very difficult to combat this pest during the summer 

 months, as the different insecticides in use have very little effect upon it 

 v/hen sprayed. The best time to cope with it is in the winter, just after 

 the trees have been pruned. The best remedv is as follows: — Take 2 lbs. 

 of potash, and dissolve in half a gallon of water, then mix in 2 lbs. 

 sulphur ; when these two are thoroughlv mixed add sufficient raw linseed 

 oil to dilute it to the consistency of paint. If the mixture should get thick 

 after standing some time, add more linseed oil to thin it down. The 

 mixture is applied by using a small paint brush, and rubbing Avell in on the 

 parts affected. This may seem a very slow process, but it is effectual. About 

 a month after the first dressing go over the trees again, and if anv blight 

 is showing, treat the spots affected. If this course is carefullv carried out 

 the woolly aphis will not give much trouble for some years. The writer 

 has used the remedy for t.hirtv years, and has always found it effective. 

 Spraving with red oil and kerosene emulsion is not nearlv so effective and 

 lasting.
