FOURTEENTH ANNUAL MEETING. 35 



Grape. The powdery mildew, Uncinula nccator, was 

 unusually prevalent last fall. It appeared most conspicuously 

 on the fruiting- pedicles and fruit. Except on the thin skinned 

 varieties, the damage was not very great. On those varieties, 

 however, not only was the presence of the fungus on the fruit 

 objectionahle for appearance, but it also induced earlier 

 wilting. 



Mulberry. This plant in Connecticut is apparently grown 

 only as a shade and not as a fruit tree. In one of the local 

 nurseries the past summer there was observed, for the first 

 time in this state, the European bacterial disease, Baeillus 

 lubouiaiius, that attacks both stem and leaves. This trouble 

 produces small cankered places on the stems that finally work 

 their way between the cambium and wood internally, killing 

 these, or else are crowded out by a vigorous growth of new 

 bark. Badly diseased branches or young trees show a yellow- 

 ish foliage and make an unsatisfactory growth. On the 

 leaves the germs form small, reddish brown, semi-pcUucid 

 areas that more or less thickly cover them. Severe winter 

 pruning is the only remedy to be suggested. 



Musk Melon. Last year, for the first time in several years, 

 growers succeeded in raising a fair crop of musk melons. 

 This was in part due to the more favorable season for growth, 

 and partly due to the absence of the downy mildew, or blight 

 (Plasiiiopara lubeiisis) that recently has played such havoc 

 with this crop. Discouraged by previous failures, however, 

 many growers last year planted no melons or greatly reduced 

 their acreage. The last two seasons have shown that the 

 downy mildew is disappearing, as is its habit, and provided 

 July and August of this year are fairly warm and not too 

 moist, little need be feared from this trouble. 



Peae/i. For the past two seasons, due to winter-kill of 

 the fruit buds, the peach crop of the state has been small. For 

 this reason, the browai rot has not been especially conspicu- 

 ous, since it does most damage with a full crop in a wet sea- 

 son. It is ^mentioned here because last spring, for the first 

 time in this state, the mature or winter spore stage of the 

 fungus was found both at New Haven and Storrs. This 

 stage develops funnel shaped bodies, about an inch in length.
