1223. Anonymous. Root-knot trouble in fruit trees. Jour. Dept. Agric. South Australia 

 22: 535-536. 1919. — A root-knot trouble affecting the peach, almond, prune and pear trees. 

 The trees become stunted and ultimately die, especially if attacked the first few years after 

 planting. The disease is most severe on sandy soil. The galls appear to be annual in char- 

 acter, vary greatly in size and are about the texture and color of a toughened turnip root. 

 The disease is now under investigation by the departmental pathologist. — Anthony Berg. 



1224. Anonymous. Yellow-leaf disease in Phormium tenax. New Zealand Jour. Agric. 

 19 : 89-93. 1919.— This article deals with a report made by L. Cockayne. The affected plants 

 have very distinctly yellowed leaves due to the fact that many of the roots are decayed. After 

 14 months study he concluded that the disease was due to a fungus or to bacteria. R. Waters 

 of the Biologist's office has isolated a fungus, but its parasitism has not been proved. A study 

 of selected plants in various locations has shown that the disease is favored by stagnant water 

 about the roots, that diseased plants may recover, and that there is very strong probability 

 that the selection of resistant plants from badly infested areas may be the best method of 

 procedure. — N. J. Giddings.

 in der Wiener gegend. [Attacks of green oak roller (Tortrix viridana L.) in the Vienna region.] 

 Oesterreich. Forst- u. Jagdzeitg. 1924: 303. November 21, 1919.— Notice of heavy attacks of 

 Tortrix viridana on oak stands in the sandstone region of the Vienna forest. The increased 

 intensity is laid to caterpillars which injured the leaves, followed by a mildew that destroyed 

 the leaves that appeared in summer following caterpillar attack. This led to a congestion of 

 sap in the roots owing to the reduction of leaf (transpiring) surface, which encouraged attacks 

 of Agarictis melleus. The trees thus weakened formed favorable hosts to the Tortrix. — F. S. 

 Baker. 



1229. Anonymous. Paste which preserves watermelons. Sci. Amer. 12 1 12 : 299. 1919. — 

 The paste described furnishes complete protection to the stem end of the watermelon, a point 

 of possible decay during transit. It is made by dissolving 4 ounces bluestone in 2 pints boil- 

 ing water and thoroughly mixing with a paste consisting of 3 ounces powdered alum and 4| 

 ounces rye flour in 1 pint of water. The mixture is cooked for 5 minutes, cooled and strained 

 through cheese-cloth, and is dyed green with pistachio green before using. — Chas. H. Otis.

1232. Arnold, Geo. Stem rot of the aster. Florists' Exchange 48: 349. 1919.— On Aug. 

 2, aster fields near Rochester, N. Y., showed discouraging prospects for seed and for cut 

 flowers. With one exception all the fields were more or less damaged by stem rot [Fusarium 

 sp.]. This was particularly true of the early varieties; and the plants of all varieties were 

 stunted by the work of the tarnished plant bug. Though it is believed that the infection of 

 the stem rot is carried over in the soil, one field on which asters had not been grown before 

 was seen to be hard hit by the rot. A probable contributing cause was a heavy coating of
