Abstract

わが国の柑橘作では,商品性(外観,品質)を高める観点から,化学合成農薬を多用することによって,病虫害を抑える方法が採られており,慣行栽培では一般に,年間10回前後におよぶ化学合成農薬の散布が行われている。一方で,「食の安全・安心」に対する消費者ニーズの高まりや,行政による諸制度の整備を背景として,近年,柑橘作においても,環境保全型栽培に取り組む生産者が増えつつある。しかしながら,柑橘作は病虫害の種類が多く,環境保全型栽培を実施する場合,病虫害対策に多くの困難が伴うと考えられる。本稿の課題は,経済的・技術的な視点から,環境保全型柑橘作における無農薬栽培の成立可能性を明らかにすることである。

The purpose of this study was to clarify the possibility of undertaking pesticide-free cultivation in environmentally friendly citrus farming. To approach this task, we conducted a survey of an organic citrus production organization in Ehime prefecture. The survey results show that there were only a few or chards where pesticide-free cultivation practices were undertaken, because disease and insect damage often occurs wherever the citrus fruit unshu was produced. Meanwhile, there were many cases where pesticide-free cultivation practices were undertaken, vis-à-vis medium- and late-maturing citrus. On comparing farming incomes on a 10-acre basis, it was found that incomes derived from farming that involved pesticide-free cultivation were lower than that involving low-pesticide cultivation.
