Fungus Diseases
Asparagus is subject to the attacks of a number of fungi, the most
widespread and destructive being the "rust," the cause of which is a
fungus described by De Candolle as Puccinia asparagi in the year 1805.
From this it is seen that
the rust upon the asparagus has been known to
scientists for nearly a hundred years, and it is but reasonable to
suppose that more or less of this fungus has existed beyond the history
of man.
The first mention of asparagus rust in the United States was by Dr.
Harkness, who claimed to have observed it on the Pacific Coast in 1880,
although it is doubtful whether the genuine asparagus rust was ever
found there. The first mention of it in the Eastern States was in the
fall of 1896, and since then its range has been widening each year. Dr.
Byron D. Halsted, of the New Jersey Experiment Station, was the first to
call attention to it, and made it the subject of careful study. The
results and conclusions derived from his experiments were published in a
special bulletin, and from this the greater part of the following has
been condensed.
