54 AGRICULTURE OF MAINE. 



applied directly after the blossoms fall and again about ten days 

 or two weeks later if the season is such as to warrant its devel- 

 opment. 



Sufficient apparatus should be at hand to insure the appli- 

 cation before it is too late to be effective. 



The dormant spray for the leaves under the trees, should be 

 applied as soon as the leaves have fallen, using lime-sulphur 

 I — II. If possible select a time when the ground is hard so that 

 the wheels will not injure the roots. Early spring plowing will 

 aid in burying the leaves so that the disease will decay and be 

 rendered harmless. 



Fruit Spot. Here is a disease that we are neglecting to notice 

 as carefully as we should. As it has been considered a regular 

 marking of certain varieties by many growers, it has escaped 

 the attention which would otherwise have been bestowed upon 

 it. Showing as dark red spots on red varieties and as red and 

 carmine spots on yellow varieties, it is very noticeable and easy 

 to detect. It has been confused with San Jose scale and resem- 

 bles it to some extent upon casual examination; on close in- 

 spection it is easily identified, however. It is also confused with 

 the Baldwin spot. 



In the sprayed orchards there has been but little of this 

 spotting, but on unsprayed trees of varieties such as Bellflower, 

 Greening, etc., it has been very abundant. 



Leaf Spot. When it is understood that this disease is pro- 

 duced by the same spores that produce canker, it is not surpris- 

 ing that we have been troubled greatly by its prevalence this 

 year. It has occurred abundantly on the foliage of unsprayed 

 trees and to some extent on those where spraying had been 

 done. 



Canker. The growers are realizing the necessity of con- 

 trolling canker if they are to save their older trees. The meth- 

 ods of controlling and the necessary precautions to prevent fur- 

 ther infection are generally known and are being more widely 

 practiced this year than ever before. Each orchard, however, 

 is usually more or less affected and we must improve in thor- 

 oughness and carefulness in our work. 



Wounds, either from pruning saws or other causes, should 

 be treated with some efficient dressing that will remain on a
