In view of all the experiments so far made, and the experiences of practical asparagus growers, Stone and Smith conclude that: "The best means of controlling the rust is by thorough cultivation in order to secure vigorous plants, and in seasons of extreme dryness plants growing on very dry soil with little water-retaining properties should, if possible, receive irrigation."
From a knowledge of the occurrences of the rust in Europe, and from observations made in Massachusetts, they are led to believe that the outbreak of the asparagus rust is of a sporadic nature, and is not likely to cause much harm in the future, provided attention is given to the production of vigorous plants.
ASPARAGUS LEOPARD SPOT
Attention was called to this new disease by Prof. W. G. Johnson, in Bulletin No. 50, Maryland Experiment Station, September, 1897. It was observed in a limited area in the asparagus growing section on the eastern shore of Maryland. The disease belongs to the group of anthracnoses, and is regarded by Dr. B. D. Halsted as a new species. In some places growers have mistaken it for the work of asparagus beetles. In general appearance it is very striking, the characteristic spots resembling the coat of the leopard. It has, therefore, been called "asparagus leopard spot," to distinguish it readily from rust. The disease has been found only in a comparatively small area, but, no doubt will be found in other places later. Asparagus growers should, therefore, be on their guard and watch it. The remedies thus far successfully used are the same as those for rust.
