38o NEW JERSEY STATE AGRICULTURAL - 



It is natural, however, to suspect that the less green foliage might 

 be more susceptible, as is true with some of the ornamental plants 

 with variegated foliage. Leaving the tomato fruits upon the 

 vines after ripening, as is clone for purposes of study, tends to 

 develop fruit fungi, but, as a rule, this has been surprisingly 

 lijnited in amount. Lifting up the vines with metal supports, or 

 tying them to stakes, is an advantage. 



Beans the present season have not suffered materially from 

 pod-spot, and the mildew of the limas was not troublesome. 

 Spraying for the prevention of the latter disease has been in 

 vogue under the general rule that delays are unwise in dealing 

 with such enemies. Last year the crop was materially damaged 

 throughout the state by the mildew. 



Squashes have not been troubled seriously with any fungous 

 enemies, but various insect pests have caused much damage, 

 especially the grub in the vine varieties. Bottle gourds were 

 much infested with an anthracnose. 



Peas, for the early varieties, escaped from any disease, but the 

 later ones became mildewed before maturing, the plants being 

 grown 'for seed and not table supply. A late crop of various 

 crosses was planted in August, after sweet corn, and the mildew 

 was kept in check with weekly sprayings of the Bordeaux 

 mixture. 



Last year the Udo^ blighted so badly that only the least-affected 

 plants were removed to a new place and the old bed was de- 

 stroyed. The plants the present season, shortly after yielding a 

 fair quantity of stems, began tO' show blight, and some of them 

 failed tO' make much growth; the others attained four feet in 

 height, but showed the blight in leaf and stem. Spraying was 

 purposely omitted, but it is possible that, with occasional treat- 

 ment, the plants might have been thrifty. 



Among the plants in the ornamental and trial grounds the 

 Solaiunn Commersonii, beginning- in September, showed a large 

 amount of the Late Blight (Phytophthora infestans) in all parts 

 of the foliage and stems. A number of trial hills of U. S. D. A. 

 novelties of the ordinai'y potatoes, growing a short distance from 

 the above relative, showed no- signs of the disease.
