No remedy has been found for the yellows. Main- taining a nearly uniform condition of soil moisture by thorough cultivation seems to be the best preventive. Ama- teurs having small plots that are sub- ject to this disease were advised to try mulching the plants to preserve uni- form moisture. The wide-spread injury caused by the tarnished plant bug was declared to be commonly attributed to other causes. Attacking the tips of the branches, it causes the blasting of the terminal buds and the dwarfing of the plant. These bugs can not be poisoned. Spraying with Whale Oil soap or kero- sene emulsion renders the plants dis- tasteful for the time being. Growing in partial shade when possible was rec- ommended, as these insects seldom work in the shade. A trial of cheese- cloth shading was suggested, where the stunted growth caused by this plant bug was prevalent. The question of growing asters for cut flowers on muck land was brought up and instances of successful trials were cited, a really remarkable growth having been obtained in some cases.
