42 APPLE MAGGOT — PLUM WEKVIL. 



nearly every one bore the crescent-shaped mark of this insect, and 

 most of them contained the worms of tlie plum weevil. In the 

 examination of nearly one thousand fallen Apples, only eight or 

 ten contained worms that did not bear the marks of this insect. 



Remedy. — The only effectual remedy for this injury to tho 

 Apple is the same as for the eodlin motli and A^jple maggot. 



Apple Scab, (Ftisicladium dendriticum) is the most injuri- 

 ous to the crop of the fungi w^hich are found on the apple tree 

 or its fruit. It causes the well-known scab or black spots on 

 the fruit. Cool weather, especially when excessively moist, 

 favors its development. Some varieties are more subject to it 

 than others. It also attacks the leaves. 



Wonderful strides have been made in the past fifteen years 

 in the discovery of new and injurious pests, and of methods of 

 combating them. Strong growing, healthy, vigorous trees 

 always withstand attacks better than weaker, unhealthy ones, 

 so the first concern of the fruit growler should be to put his 

 trees in the best of health through culture, feeding and prun- 

 ing. The most approved way at the present time of combat- 

 ing most of the pests of fruit trees and plants is to apply the 

 remedy in the form of a spray, covering the whole plant with 

 a very fine mist. 



For Eating Insects, such as the eodlin moth, canker worm 

 and tent caterpillar, arsenical poisons are used, paris green 

 being the most common. This is used at the rate of one pound 

 to 150 or 200 gallons of water, and is applied before the buds 

 open, as soon as tlie blossoms have dropped and once or twice 

 again at intervals of ten days or two weeks. 



For Sucking Insects, such as the plant louse, woolly aphis, 

 etc., some substance whic^h will kill them on contact must be 

 employed. Whale oil soap dissolved in water, one pound to 

 six to ten gallons, is a good remedy. Kerosene, when it can be 

 applied with a suitable pump, at tlie rate of one part kerosene 

 to fifteen parts of water, is effective. Kerosene emulsion is
