If this must be done, then plough and thoroughly pulverize or cultivate such soil in the fall, thus disturbing and killing many grubs, pup®, and recently- formed beetles. It will also pay to stir the soil frequently be- fore and after setting the strawberries in the spring or summer, as thorough cultivation is a great discourager of white grubs. Salt or similar applications to the soil around the plants rarely give relief. Experienced strawberry-growers can usually detect an infested plant, and they often practise the sure and not difficult method of digging out the culprit; the relieved plant often pays for the trouble later on. The Strawberry Root-louse {Aphis forbest) is a very small greenish-black plant-louse which attacks the roots of straw- berries. In Maryland, New Jersey, and Delaware, it is said that hundreds of acres of vines have been rendered valueless by these lice. The insect also occurs westward through Ohio, Illinois, and into Wisconsin. It is a comparatively new pest,.
