Add water to bring the resulting compound up to 2 gallons. Use 1 or 2 quarts of this stock solu- tion to 50 gal- lons of water or Bordeaux. London Pur- ple. â This is used in the same propor- tion as Paris green, but as it is more caustic it should be ap- plied with two or three times its weight of lime, or with the Bordeaux mixture. The composition of London purple is variable, and unless good reasons exist for supposing that it contains as much arse- nic as Paris â green, use the latter poison. There are many proportions in which the ingredients are combined to make Bordeaux mixture. The 6-4-50 for- mula is not now often used, as the amount of copper sulfate (or blue-stone) is greater than need be. The 3-4-50 formula is now much used. Make stock solutions by dissolving 1 lb. sulfate to 1 gal. water in a barrel; and by dry-slaking the lime and then Anrhracnose Spores muct; maqnifiecix^ JSeedCoat" Starcli Gi-aias Fig. 58. How a fungus works in a bean pod. To the left above is a diagram of a section across a bean pod flirough an antliracnose canlser. The large drawing below is a much enlarged view of a part of this same section. It is largely diagramjnatic. It shows how the mycelial threads of the fungus may penetrate the seed-coat and enter the starchy tissue of the seed, there to remain dormant until the following season. On the left of
