Ammoniacal Copper Carbonate | |
---|---|
Copper carbonate | 5 oz. |
Ammonia (26° Baumé) | about 3 pt. |
Water | 50 gal. |
Dissolve the copper carbonate in the smallest possible amount of ammonia. This solution may be kept in stock and diluted to the proper strength as needed.
Use this instead of the Bordeaux mixture after the fruit has reached half or two thirds of the mature size. It leaves no spots as does the lime-sulphur wash or the Bordeaux mixture.
