良質米病蟲害綜合防治研究

Studies on the Integrated Pest Management for Quality Paddy Rice

摘要


良質米病蟲害防治示範田分別設置於雲林及台南縣,示範區插秧前全面清除田邊雜草。第一期作於插秧前或初期施用粒劑防治二化螟蟲,分蘗初期預防稻熱病及紋枯病。抽穗前5天防治穗稻熱病、二化螟蟲、瘤野螟及飛蝨類害蟲;齊穗期再施藥一次防治穗稻熱病。第二期作於插秧初期施用粒劑防治二化螟蟲及稻心蠅,分蘗初期預防紋枯病,孕穗初期防治白葉枯病及瘤野螟。結果顯示,示範區兩期作的病蟲害發生情形均較對照區為低。二示範區兩期作每公頃平均減少防治成本2,416元,產量增加3%,增加收益5,552元。

並列摘要


The demonstration rice fields were set up at Yulin and Tainan in 2003. The weeds in and around the test field were removed before planting. In the first crop, rice stem borer was controlled at the early seedling stage by using granule pesticide, and rice blast and sheath blight were controlled at the early tillering stage. Rice neck rot, rice stem borer and rice leaf folder were controlled 5 days before heading. In the second crop, rice stem borer and whorl maggot were controlled at the early seedling stage by using granule pesticide, and sheath blight was controlled at the early tillering stage . Bacterial leaf blight and leaf folder were controlled at the early booting stage. The results showed that the pests of demonstration fields were lower than those of check fields. The average cost for pest control at the demonstration fields were 2416 New Taiwan Dollars (NTD) lower than the check plot. However, yield increased 3% and profit increased 5552NTD.
