raying began June 2d, and
ten sprayings were applied during the season. The applications were made
with a knapsack pump, and therefore were far more expensive than they
would have been if the sprayings were made with horse-power. With the
fungicide costing $5.00 per acre, and a machine that would spray two or
more rows at a time, it would be possible to reduce the cost to $10.00
per acre, or even less. In effectiveness the soda-bordeaux stood first.
Between the other fungicides there was but little difference. The best
results showed a reduction of rust of about one-quarter, which is not as
satisfactory a result as had been expected.

In the spraying work conducted by Professors G. E. Stone and R. E.
Smith, at the Massachusetts Experiment Station, the results were more
encouraging. The solutions used were potassium sulfide, saccharate of
lime, and bordeaux mixture. The spraying was done with a knapsack
sprayer, provided with a Vermorel nozzle, and after the first
application it became evident that the practice was of little importance
on account of the difficulty in making the solution stick to the plant.
For successful spraying of asparagus a finer nozzle is required than any
that is now in the market.

In some other experiments carried out on a small scale the asparagus
plants were practically covered with solutions, when they were put on
with an ordinary cylinder atomizer, and the lime solutions showed
excellent sticking qualities; but with the ordinary coarse nozzle the
solutions would run off of the glossy epidermal covering of the plant
very readily. Should the spraying of asparagus ever become a necessity,
then some apparatus which can be strapped to a horse's back should be
used. The narrow space between the rows forbids the use of the ordinary
mounted appliances, and if spraying is to be carried on upon a large
scale, it would be better to have the spraying mixture carried in some
manner on the horse's back. In this way it would be possible to carry
some thirty or forty gallons of mixture through the narrow rows.

_Burning the affected tops._--There can be no doubt that by the burning
of the infested brush, after the cutting season, innumerable rust spores
are destroyed. But if this is done before the stalks are entirely dead
new ones will spring up at once, and in a few days will be as badly
affected as the first. The burning of the tops in the summer has,
moreover, a decidedly injurious effect upon the root
