Fungoid disease and mildew often attack the pansy in hot, muggy weather.

The remedy for the former is to spray with the Bordeaux mixture, and for the latter to dust with sulfur.

It will be better still if the disease appear in August, as is usual, to remove all the old growth, cutting or breaking it off close to the crown, care being taken not to injure the tender new shoots, which will have started by this time.

Burn the old tops.

The rose especially is in need of constant care and watchfulness from the swelling of the leaf bud until the end of the growing season.

The first experimental work on the control of this disease so far as I know was carried out by Dr. I.C. Curtis of Fulton, New York, having suffered the total loss of foliage and seed crop during the season of nineteen oh four.

Dr. Curtis determined to test the efficacy of the Bordeaux mixer the following season as a preventive of the blight.

The success of this work, together with his method of making and applying the mixture, is given by him in special crops for January nineteen oh six.

Extensive experiments in spraying were carried out during the past seasons by the Ginseng Company at Rose Hill, New York under the direction of the writer.

During nineteen oh five, their entire seed crop was completely destroyed by the blight.

Losses from the same disease the previous season have been very heavy.

During nineteen oh five, they had succeeded in saving a very large proportion of their seedlings by spraying them with the Bordeaux mixture.

Encouraged by this, they began spraying early in the spring of nineteen oh six, just when the plant began to come through the ground.
