  • Three type of Lime Bordeaux mixture (LBM) that has been used since 1800's for control plant disease are used for eco-friendly ginseng (Panax ginseng) disease control. But it was restricted the use in the crops cultivation in some countries of Europe recently, because there is a possibility that the copper component is concentrated in the soil and plants with using LBM containing copper. According to the concentration and number of LBM spraying treatment, it was investigated copper and other components in soil and ginseng root. In case of LBM sprayed 33 times for three years, copper concentration was increased up to 75.9 ppm in the soil. However copper concentration of ginseng root was increased with 9.9~23.0 mg/kg in comparison with 8.38~11.39 mg/kg at LBM non-treatment. It has shown that the copper components can be concentrated to in the soil if used continuously in the long term.

  • Organic materials, such as chitin incubated solution (CIS) combined with neem oil (NO), nano silver silica (NSS), and Bordeaux mixture (BDM), were applied with and without agricultural chemicals (AC) (insecticide and fungicide) to investigate scab and mealybug occurrences and fruit qualities on 'Niitaka' pear trees in orchards in 2006. Fruits and leaves grown under CIS+NO without AC had less than 30%, scab occurrence, but CIS+NSS or CIS+BDM without AC had higher scab occurrence. Organic materials with AC decreased the scab to less than 20%. All treatments decreased mealybug occurrences to less than 10%, except for the fruits grown under CIS+BDM without AC. Fruit qualities varied among the treatments. Hunter value a, representing for the redness degree, was higher for fruits treated with CIS+NSS and CIS+BDM without AC than those with AC. Fruits treated with organic materials without AC had greater total phenolic and flavonoid compounds as well as antioxidant capacity in flesh and greater total phenolc compounds and antioxidant capacity in peel than those treated with the AC.

  • 우리나라에 제일 먼저 도입된 과수는 사과이며 그후 경제적인 과수원이 조성된것은 1901년이고 국가적인 차원에서 시험연구사업이 시작된 것은 1906년부터이다. 과수병의 연구는 1910년 부터 배나무 붉은별무늬병을 비롯하여 몇가지 병에 대한 약제방제시험으로부터 시작되었다. 본격적인 농약으로서의 살균제는 석회보르도액이며 1945년 이전까지 주로 과수원에서만 사용되어 왔다.
