There maybe two or four broods a year. It is, therefore, important thatthe first brood be controlled. Some poisonous insecticide shouldbe used for this purpose. Since it is now necessary in mostplaces to spray the foliage to preserve it from fungous diseases,it is wise to combine the insecticide with the fungicidal sprayused at this time. If the spraying is done as soon as the plantshave finished blooming and before the currants are large nodanger of getting poison on the fruit is incurred, but it is not.
