전남지역 쌈채류 무농약.유기재배농가의 잡초, 병해충관리 실태분석
Survey of Diease and Weed Control in Organic and Free-pesticide Cultivation of Chunnam Area 'Ssam' Vegegable
초록
전남지역의 쌈채류 무농약 유기농산물 생산농가의 잡초관리, 병해충방제 기술과 농자재의 사용실태를 조사 분석하여 그 기술을 검증하고 표준화하여 정립된 기술을 개발하고자 상추, 들깻잎, 치커리, 케일 등 쌈채류 재배로 무농약 유기농산물 품질인중을 받은 21농가(무농약재배 16, 유기재배 5)를 대상으로 재배실태를 조사하였으며, 그 결과를 하면 다음과 같다. 종자 파종시 종자소독을 실행한 농가는 28.6%에 그치고 소독방법은 소금물가리기, 키토산액 침지 등 검정되지 않은 간이방법으로 수행되었다. 육묘 중 묘상에서의 병 방제를 위한 친환경 농자재의 살포 횟수는 55.6%가 살포 횟수가 없었으며, 해충 방제를 위한 살포횟수는 1회 살포가 50.0% 이었다. 따라서 육묘 기간이 비교적 짧은 쌈채 작물에서의 육묘 중 병해충 방제를 위한 농자재 살포횟수는 1회
For developing standard method for diease, pest and weed control in environmental friendly 'Ssam' vegetable cultivation, this study was carried out to investigating agriculture material use in organic agriculture and no pesticide cultivation for lettuce, kale, leafy perilla and korean cabbage. The 28.6% of investigated farmer carried out seed sterilization by seed selection with salt solution and soaking in chitosan that not validated. For raising seedling periods, the 55.6% of farmer did not use environmental-friendly agriculture material for, diease control and the 50% of farmer used one time for. pest control. Therefore, the control of disease and pest could be achieved with one or two times use of environmental-friendly agriculture material. Seed sterilization was carried out by soil solar sterilization, one time per year in 71.4% of farmer. Weed was controled by black PE film for weed germination of furrow in many farmer, by man-power weeding for weed of ridge in 85% of farmer and by machine weeding and mulching in some farmer. During cultivation period, the major pest were Aphis gossypii in lettuce, Plutella xylostella in kale, Plutella xylostella and Phyllotreta striolata (Fabricius) in korean cabbage and Pyrausta panopealis (Walke) in feat perilla. The many farmers used environ-mental-friendly agriculture material for control of pest over 10 times for spring season, and more used sold materials in market than home-made materials. In result, it needs to develop standardized method and validate cultivation methods for control of disease and pest, and seed sterilization treatment environmental-friendly 'Ssam' vegetable.
