 winter-wheat seed.] Mitteil. Deutsch. Landw. Ges. 35:486-487. 1920.— The Agricultural 

 Institute in Munich has worked for the development of an organization involving the em- 

 ployment of inspectors charged with the duty of instructing farmers in the details of seed 

 treatment and enforcing the requirements that all seed be treated. The author recommends 

 "fusariol" as a practical fungicide for prevention of bunt (Tilletia sp.), and adds that its use 

 results in improved stand and yield. He compares "fusariol" with formaldehyde, "uspu- 

 lum," "fusafine," and a new fungicide, "sublimoform." The author warns against the use 

 of copper sulphate because of injurious effect on germination. For control of barley stripe 

 disease {Helminthosporium graminium) he recommends a 0.25 per cent solution of "uspu- 

 lum" as the most satisfactory of fungicides employed in his experiments. In the preven- 

 tion of Fusarium infection in rye the author obtained best results as to stand and yield when 

 he used fusariol. Very satisfactory results were obtained also from the use of "uspulum." —

 —Spraying for control of apple scab with (1) Bordeaux mixture containing excess of lime, 

 "soluble sulphur" being used for the calyx spray, (2) lime-sulphur solution, and (3) sulphur 

 dust. The first gave best control, and in the case of Mcintosh Red, a slightly greater yield 

 than lime-sulphur. Sulphur dust gave very poor control, 86.95 per cent of the fruit of 

 Mcintosh Red being scabby. — J. W. Eastham.
