late spring- or early snniiner as purplish patches on the young 

 canes, beginning at the lower nodes and appearing higher as 

 the leaves drop off. These spots eventually run into each other 

 somewhat. In the fall and- succeeding winter these canes 

 become whitish, and by spring are dotted with the small, black, 

 mature fruiting pustules that spread the disease to the young 

 canes. While this trouble does not kill the canes it undoubtedl\- 

 aft'ects their fruitfulness and vigor. There is another cane 

 blight that causes more evident injury to the canes as it often 

 girdles them with a dead area, causing the parts above to wilt. 

 Some of our growers have been seriously bothered by the fruit 

 wilting about the time of maturity, l)ut I have not yet ascertained 

 whether this latter trouble has been responsible for this. 



Yellozvs. There is another trouble common in our raspberry 

 which has very properly been termed the yellows. This seems 

 to be a physiological trouble, and is characterized by sickly 

 looking foliage which is usually streaked with yellow and more 

 or less curled. Very often this appearance is seen in vines 

 also affected with the cane blight. It may be, in some cases, 

 a lack of proper plant food that is responsible for the trouble.

Frosty Spot. The last host with which we have to deal is 

 the strawberr}'. No serious trouble has been reported for this 

 the past season. The effect of the late fall fruiting remains to 

 be disclosed next summer. There was, however, one curious 

 trouble shown late in the fall in some patches near New- Haven. 

 I have called this frosty spot, because the appearance was not 

 unlike frost or the mildew fungus on the upper surface of the 

 leaves. This appearance was evidently due to the flaking up 

 of the cuticle and eventually to the rupture of the epidermal 

 cells when the frosty appearance gave way to dead brown spots. 

 The trouble w^as a physiological one, no doubt induced by 

 peculiar weather conditions coupled, perhaps, with the method 

 of cultivation, the trouble being most pronounced in young 

 plants grown between rows of early potatoes. The trouble was 

 called to the attention of the writer by growers who feared it 

 might be the beginning of a serious fungous disease. 

 Respectfully submitted,
