非農藥防治新技術的開發與應用

Abstract

近年來我國開發的非農藥病害防治新技術甚多，在此簡單介紹數項田間實際推廣應用的新技術，包括亞磷酸簡便使用法（可以有效預防卵菌引起的眾多病害）、乳化葵花油（預防與治療白粉病與其他葉部病害）、排水防治蕹菜青枯病與茭白基腐病、溫水處理抑制檬果炭疽病與山藥種薯線蟲。 Many new measures, other than application of synthetic pesticides, have been successfully developed for management of various major crop diseases in Taiwan in recent years. Here we introduce certain important measures developed by the researchers in the Taiwan Agricultural Research Institute and some of them have been transferred to the private companies for commercial production. These measures include that (1). the simple technique for application of phosphorous acid to control oomycetes diseases, (2). The emulsified sunflower oil for control of powdery mildew and other foliar diseases, (3). use of percarbonate salts to control crop foliar diseases, (4). Appropriately draining-off field water to control water spinach bacterial wilt and water bamboo basal stem rot, and (5). use of hot water treatment to suppress the postharvest mango anthracnose and yam seed tuber nematodes.
