Abstract
These experiments were carried out during 1960 in Tainan Fiber Crops Experiment Station, Taiwan Agricultural Research Institute, Taiwan, Republic of China. Ten per cent Thimet granules was applied by in-furrow at the rate of 1 (A treatment) and 2 (B treatment) of toxicant per acre and side dressing at the rate of 2 (C treatment) and 4 pounds (D treatment) of toxicant per acre after 42 days planting. Side dressing treatment was added at the rate of 4 pounds of toxicant per acre after 73 days planting on the plot of A treatment.
Thimet furrow treatment controled leafhopper significanlly during 53 days and aphid during 72 days. Thiment side dressing treatment gave good leafhopper and aphid control during 49 days and it elongated about 80 days length. Thimet treatment gave no control effect on pink boliworm and spotted boliworm.
The range ef yield was A>D>B>C>CK, its yield per hectare were 886.4, 811.3, 795.8, 725.0 and 580.5 kg. resp., and its index were 153, 140, 137, 125 and 100 resp.
本試驗于1960年間，於臺南棉麻試驗分所農場舉行。使用10% Thimet 粒劑，計分4種處理。即在播種棉籽時，于棉籽旁每英畝使用Tllimet（以Technical計算）1磅（A處理）及2磅（B處理），另於播種棉籽後42天于棉採旁每英畝條施 Thimet 2磅（C處理）及4磅（D處理）。A處理在播種後73天，另條施每英畝 Thimet 4磅。
A及B處理，經施用Thimet後53天，對棉浮塵子防治有顯著之效果，對棉蚜蟲防治則有72天之效果。C及D處理，對棉浮塵子及棉蚜蟲之防治有效期間，有49~80天之久。對主耍棉鈴害蟲，大紅鈴蟲及綠帶金鋼鑽，各處理均無防治效果。各處理之籽棉產量高低順序為 A > D > B > C 對照區（CK)，其產量每公頃為886.4，811.3，795.8，725.0及580.5公斤，產量指數各為153：140：137：125：100。
將1公分量之10% Thimet粒劑置於棉籽下部1公分處，或與棉籽接觸時，顯著的減少棉籽發芽率。如置於棉籽旁邊3公分處，則無任何葯害現象。
