Leaf Blister Mite. 



The leaf blister mite cuases serious da-iiage to the foliage 

 by mining in the leaves between the upper and lower epidermis, 

 causing dead areas or blisters to appear kherever they have 

 worked. During the winter-i.e., from the time the leaves begin to 

 fall till the buds begin to open in the spring the mites live 

 underneath the bud scales. It is duriag the period of their 

 migration from the leaves to the stems, or when they emerge in 

 the spring to infest the young foliage that they can be reached b i 

 a spray. The time to spray, therefore, is in the fall just 

 after the leaves have fallen, or in the spring just before the 

 buds open. It is useless to spray for them later than this, for 

 once they get inside the leaf, they are protected and cannot be 

 reached. Any contact spray such as lime sulphu^or the miscible 

 oils, is efficient in controlling this pest. Usually the spray 

 applied in the spring for the scale will usually get the raite 

 if applied late enough. If sprayed for at the proper time, there 

 is little difficulty in controlling it. 



Apple Scab, 



This is a disease known as "Scab"", "therungous" or ''Black 

 Spot". It is very distructive and attacks both the fruit and 

 foliage. It is caused by a minute fungous which grows just under 

 the cuticle of the apple and when ready to form spores or •'seeds" 

 pushes the cuticle up and shoves it to one side causing a dark 

 s-ont or scab to appear. The spores are disseminated through the
