GOOSEBERRY ENEMIES
The currant-worm attacks the gooseberry also, and is effectively handled by the arsenate of lead, Paris green or hellebore spraying, mentioned above.
The great trouble in growing gooseberries successfully is the powdery mildew—a dirty, whitish fungous growth covering both fruit and leaves. It is especially destructive of the foreign varieties, the culture of which, until the advent of the potassium sulfide spray, was being practically abandoned. Use 1 oz. of potassium sulfide (liver of sulphur) to 2 gals. water, and mix just before using. Spray thoroughly three or four times a month, from the time the blossoms are opening until fruit is ripe.
