Abstract

本試驗棉田施用5% Di-Syston (0,0-diethy1 S-2-ethylthio) ethyl Phosphorodithiotaeioate)粒劑，分播種同時施用與播種後二個月施用等二種方式，每次每英畝用有效成份1或1. 5, 2, 3,磅等。結果以與棉播種同時每英畝施用有效成份一磅，即可有效防治棉浮塵子）Chlorita biguttula Ishida)與棉蚜蟲(Aphis gossypii G.)，並可促進棉株高度之生長。對籽棉之產量亦種顯著地增加。但Di-Syston對棉鈴害蟲（棉鈴蟲，金鋼鑽及紅鈴蟲）則無效果。如能配合地上部噴藥，保護棉鈴，減少棉鈴害蟲之驅除，本劑在棉作治蟲上仍有使用價值。 In this experiment, 5% Di-Syston (0,0-diethyl S-2-(ethylthio) ethyl phosphorodithioate) granular was used for determining the effect of controlling cotton insects. One, 1.5, 2 and 3 pounds per acre of Di-Syston were applied into the soil by side dressing in one-and two-application treatments. According to the results, one pound per acre of Di-Syston applied at the time of sowing was sufficient to give very effective control of the cotton leafhopper (Chiorita biguttula Ishida) and the cotton aphis (Aphis gosypii G.). Vigorous growth of cotton plants and significient yield increase were also observed. On the other hand, the application of Di-Syston had only poor effect for controlling the cotton boll insects, including the cotton pink boliworm, boliworm, and the spiny boliworm. If several sprays of insecticides for boll insects could be followed with Di-Syston application, might have practical value of controlling various kinds of cotton leaf insects.
