At Harbor, Oregon, season-long protection of field-grown lily plants from aphid attack has been obtained from applications over bulbs in the furrow of granulated phorate and Di-Syston® (O,O-diethyl S-2-(ethylthio)ethyl phosphorodithioate). Mixing granules in the soil before setting the bulbs was also effective, as well as applying carbon dust formulations directly to the bulbs. Soaking bulbs in dilute emulsions or demeton, phorate, or Di-Syston was effective to a lesser degree. Chiefly involved were the foxgrove aphid (Myzus solani (Kitb,)), the melon aphid (Aphis gossypii Glov), and the western lily aphid (Macrosiphum ,scoliopi Essig). The shallot aphid (Myzus ascloonicus Doncaster), the potato aphid (Myzas cuphobiae (Thonmas)), and the green peach aphid (Myzus persicae (Sulz) appeared in small numbers.
