“…최근에 식량작물뿐만 아니라 다양한 채소종자의 종자전염성 병원 균 방제 및 생육 촉진을 위한 온탕침지법 적용에 대한 연구 결과가 보고되었다 (Nega et al, 2003;Fukushima et al, 2015;Michalczyk et al, 2019). 국내에서는 오래 전부터 온탕침지법은 벼 키다리병(Gibberella fujikuroi) 방제, 맥류 깜부기병(U. nuda) 방제를 위해 널리 활용되어 왔다 (Park et al, 2003;Park et al, 2008;Roh et al, 2011). 그러나 국내에서 온탕침지법을 이용한 채소 종자 소독에 적용한 연구 사례는 매우 적은 것으로 알려져 있다 (Lee et al, 2007;Kim et al, 2018).…”

The purpose of this study was to estimate the efficacy of 2% baking soda (sodium bicarbonate) and ultra-sonication on the fungi and bacteria disinfection and germination of organic vegetable seeds. The predominant fungi and bacterium were Altanaria sp. and Pseudomonas sp. in organic vegetable seeds. The treatment of 2% baking soda alone showed low germination rate of organic root, leafy vegetable and cucurbit seeds, but the germination and disinfection efficacy was increased by the combined treatment with 2% baking soda and ultra-sonication. Among the vegetable seeds, Radish, turnip, Chinese cabbage, and cabbage treated with 2% baking soda and ultra-sonication for one minute had the highest disinfection and germination efficacy. Also, beet, melon and watermelon were the highest disinfection and germination efficiency for 2 minutes of the combined treatment with 2% baking soda and ultra-sonication. In the future, the eco-friendly seed disinfection technology using ultra-sonication and baking soda is more effective and economical methods, so we need to expand research on other organic crops.

To investigate the effect of soluble silicate zeolite dressing of the rice against bakanae disease, field trial in reclaimed land and in vitro were carried out. The coated rice seeds (SCS) which were dressed with the mixture of 25% silicic acids (binder), and the zeolite (coating powder). In wet direct seeding, uniform scattering of rice seeds on the soil surface and the better seedling establishment were shown in SCS treatment plots. The incidence of bakanae disease began from the mid tillering stage toward the heading stage. Around heading stage, the ratio of infected tillers reached its highest point by 9.9% in non-SCS treatment plots. While, in SCS treatment plots, the ratio of infected tillers was no more than 0.01%. The vitality of the pathogenic fungi of bakanae disease in the SCS and non-SCS samples were assessed. Samples were incubated for one week keeping proper humidity at 30°C after inoculated with panicles of infected rice plants from experimental field plots. In non-SCS treatment, pinkish colonies were formed on the grain surface of panicle of infected plants, and mycelium, macro-conidia and micro-conidia were developed actively inside part of infected grain inoculated. While in SCS treatment, micro-conidia and mycelium were not survived and the growth of macro-conidia, mycelia were greatly inhibited and withered. Based on the results, it is concluded that the environmental friendly control of bakanae disease by use of SCS is possible and soluble silicate can be applied as agents for replacement of seed disinfection.

“…Bakanae disease occurs during the seeding period of the following year, after which F. fujikuroi winters inside of the seed (Park et al, 2008). The symptoms of Bakanae disease include succulent growth and seeding, after which the seed leaf does not emerge, followed by withering of the seed.…”
