 [Spraying potatoes in Holland.] Jahresb. Verein. Angew. Bet. 16: 132-138. 1918. — Spraying 

 for potato blight (Phytophthora) is much commoner in Holland than in Germany. It is 

 particularly necessary in the provinces near the sea. Two treatments beginning late in 

 June are important. A third treatment often is necessary. In Friesland six treatments 

 may be made, depending on conditions. Bordeux or Bungundy mixture is used of 1.5 per cent 

 strength and is applied at the rate of 750 to 1000 liters per hectare. Increased yield from 

 spraying is sufficient to pay the cost of application. — Brief discussion is given of resistant 

 varieties. — D. Reddick.

 of 1920. Quart. Bull. 22; Virginia Crop Pest Commission. 4 p. 1920.— Of a total of 157,030 

 apple trees inspected during the period covered by the report slightly more than five per cent 

 were discarded on account of crown-gall. The percentage of defective trees from various 

 nurseries ranged from zero to as high as forty per cent. The details of the inspection are 

 shown in tabular form, with the nurseries from which the shipments originated grouped by 

 states. The apple stock which was grown in Virginia nurseries averaged 2.14 per cent 

 affected with crown-gall, while that which originated without the state averaged 5.55 per cent.

 1920. — An exhibit of fungous diseases of Hevea brasiliensis in Cejdon and Malaj^a prepared 

 by J. B. Farmer and opened March 10, at the Imperial Coll. Sci. and Tech. Several diseases 

 are of great importance to the rubber industry. Principal diseases in exhibit: (1) Brown 

 Bast, most important so far, perhaps of bacterial origin: (2) Fomes lignosus on roots, second 

 in importance; (3) Fomes pseudoferreus , also on roots; (4) Dry Rot ( Ustulina zonata), a wound 

 parasite; (5) Patch Canker {Phytophthora faberi) a bark disease which is increasing; (6) 

 Stripe Canker (Phytophthora sp.), affected 70 per cent of trees on some estates in 1915-17; 

 (7) Pink Disease {Corticium salmonicolor) . — 0. A. Stevens.
