非化學農藥新技術在蔬果類病害防治上的應用

Abstract

在教育認知與輿論宣導下，如何善待環境，已是世界各國在制定法規所必須依循的政策。特別是在有機農業與永續農業的發展下，病蟲害的管理多已朝向使用安全且有效的非農藥防治方法；其中包括有健康種苗、抗病育種、誘導性抗病、交互保護、拮抗微生物、非農藥殺菌物質與營養液、高分子聚合物、土壤添加物、栽培管理與物理防治法等；最近台灣在此方面發展更有使用重碳酸興、磷鉀肥、植物油及礦物油、植物抽出液與生物殺菌劑等。 Greater attention by academia and user to reduced risk agendas (human and environment) of a crop protection strategy will greatly aid a sustainable growth of nonchemical pesticides including microbial pesticides, plant derived pesticides, natural materials, pathogen-free materials, resistant varieties and physical methods. These materials will be as alternatives to chemical pesticides for the control of plant pests on developed and developing countries. At present time, there have been developed new techniques as described above in Taiwan. These used materials included salts of carbonic acid, phosphorous acid, plant oils, plant extracts and microbial fungicides.
