Abstract
In the experiments, each insecticide spray applied at a rate of 0.96 or 1.25 kg per hectare, but endrin and ekatox sprays gave better than folidol sprays, local formulation. folidol and formulation folidol from abroad were equally effective in controlling the paddy borer. Each fungicide comtined with insecticide spray applied at a rate of 0.80 to 0.91 or 1.6 kg per hectare were nearly equal in effectiveness against this disease. But tuzet gave better than thiotox. 0.03% tuzet spray produced not significantly increase in yield over that produced by 0.05% tuzet spray and may be Promising for sheath blight control. Excellent control of paddy borer and sheath blight was obtained with 0.04% of insecticide combined with 0.03% tuzet or 0.05% thiotox sprays in all the experiments.
三化螟及紋枯病為二期作主要病蟲害，其發生和為害時期，概為大同小異，因此，殺蟲劑殺菌劑混合後舉行防治，頗為理想，藉以減低防治勞資成本，本試驗參加之殺蟲劑4種，即本省加工之46.7%富粒多(Folidol)，國外加工46.7%富粒多，50%益加斯（Ekatox）及19.5%安特靈（Endrin）等乳劑；殺菌劑兩種，即100％多穗（Tuzet）及82％Thiotox可濕性粉劑等，每公頃施用殺蟲劑有效成份，0.96-1.5kg，其防治成果，大致相等，其中以安特靈及益加斯稍較富粒多為優，但本省加工富粒多和泊來品者，均無顯著差異。殺菌劑每公頃施用有效成份0.80，0.9 1及1.6kg防治紋枯病效能，均無顯著差異，其中以多穗稍較Thiotox為優，惟多穗高濃度處理者，對於稻穀產量似無顯著差異，0.04%殺蟲劑及0.033%多穗或0.05% Thiotox防治三化螟及紋枯病，均獲有效成果。
