Analysis of Pesticide Applications on Apple Orchards in Geochang, Korea

거창지역 사과원 농약사용 실태분석

This study surveyed the selling, buying, usage, selection and spraying frequency of pesticides on apple orchards in Geochang, Gyeongsangnam-do province from 2012 to 2013 and found that the fungicides, insecticides and acaricides were sprayed $13.9{\pm}3.5$, $12.6{\pm}3.2$, and $2.6{\pm}1.3$ times per year, respectively. Fungicides were applied mainly to control for Diplocarpon mali, Colletotrichum gloeosporoides and Alternaria mali, whereas insecticides were sprayed mostly to control Grapholita molesta, Carposina sasakii insects. Dealers sold pesticides without monitoring of the pests in the apple orchards, and also sometimes sold pesticides which are non-registered for apple. Most of the farmers were highly relied on dealers' recommendations to choosing the brand product. Relating on Integrated Pest Management (IPM) on apple orchards in Geochang, residual active ingredient of frequently sprayed fungicides, insecticides, and acaricides were analyzed. Most applications of the fungicides, insecticides and acaricides were well corresponded with FAO's recommendations. For production of safe food and use of pesticides, it is requested to develope control calender and consideration of training program for farmers. The regional characteristics and environmental situation of the farm also should be considered.

거창지역에서 사과재배 50농가를 대상으로 2012년부터 2013년까지 2년간 사용농약 및 사용량, 선택방법, 살포실태 등을 분석한 결과, 연간 살균제는 $13.9{\pm}3.5$회, 살충제 $12.6{\pm}3.2$회, 살비제 $2.6{\pm}1.3$회를 살포하였으며, 살균제는 갈색무늬병, 탄저병, 점무늬낙엽병, 살충제는 복숭아순나방, 복숭아심식나방, 응애류 등을 방제하기 위하여 주로 사용되었다. 농약판매상은 병해충의 발생을 현장에서 직접 파악하지 않고 농약을 판매하였으며, 적용작물에 등록되어 있지 않은 농약을 판매하는 경우도 있었다. 대부분의 농민들은 농약을 스스로 선택하지 못하는 등 판매상에 대한 의존도가 82.5%로 매우 높았다. 병해충종합관리(IPM)체계와 관련하여 거창지역의 사과원에서 살포되는 살균제, 살충제, 살비제의 성분조사를 통해 실질적으로 빈번하게 살포되는 농약을 분석하고, FAO의 권장기준에 부합하는지 비교한 결과 대부분의 약제가 권장기준에 부합하였다.
