Control of powdery mildew with potassium bicarbonate and polyelectrolyte
No full text測試0.5、1.0 及2.0% (w/v) 碳酸氫鈉、碳酸氫鉀及碳酸氫銨等三種重碳酸鹽對番茄白粉病菌(Oidium neolycopersici)、豌豆白粉病菌(Erysiphe pisi) 及玫瑰白粉病菌(Sphaerotheca pannosa)等孢子發芽的影響，發現均可有效降低孢子發芽率，其中以碳酸氫鈉與碳酸氫鉀的效果最佳，且在0.5% (w/v) 時即可表現顯著(p 0.05)，三者的防治率均達83.2% 以上；而聚電解質的抑病效果則較其他三種處理的效果為差，且聚電解質與碳酸氫鉀混合液並未能增進病害防治效果。由豌豆白粉病的田間試驗發現，噴水處理亦具有抑制白粉病的效果，與對照不噴水處理之間呈顯著差異(p < 0.05)。綜合三個田間試驗結果，顯示0.5%(w/v) 碳酸氫鉀的防病效力與化學藥劑無異，可推荐給農民使用。
Sodium bicarbonate, potassium bicarbonate and ammonium bicarbonate were evaluated for their inhibitory effect on spore germination of three powdery mildew pathogens, Oidium neolycopersici, E rysiphe pisi, and S p h a e rotheca pannosa. Data showed that the spore germinations of these pathogens were significantly (p<0.05) suppressed by all three bicarbonates, especially sodium and potassium bicarbonate at 0.5% (w/v). Detached leaf method also was used to evaluate 0.5% (w/v) bicarbonates and 0.03% (w/v) polyelectrolyte (FO4490SH) for control of powdery mildew. The result showed that all treatments except ammonium bicarbonate reduced the infection area of powdery mildew on tomato leaf surfaces, especially sodium and potassium bicarbonate. Three field trials were conducted in central Taiwan to evaluate the applicability of potassium bicarbonate, polyelectrolyte and fungicides for control of tomato, pea and rose powdery mildew. Each trial was arranged in a completely randomized design with four replications. Potassium bicarbonate at 0.5%, and 0.5% potassium bicarbonate plus 0.03% polyelectrolyte were effective in decreasing the disease severity of powdery mildews on all three crops tested. The treatments were as effective as fungicides. The percentages of disease control in all three treatments were more than 80%. The severity of powdery mildew was only slightly reduced by the treatment of polyelectrolyte alone on tomato and pea. Polyelectrolyte did not increase the efficacy of disease control by potassium bicarbonate in this study. Spray with water also slightly reduced the disease severity of powdery mildew on pea in comparison with no water spray. This study showed that 0.5% potassium bicarbonate could be used as an alternative method for control of powdery mildew in the field

No full textTelling stories: a metagame description of a conflict
No full textThis paper describes the use of metagame analysis to describe and explore a conflict situation. The analysis was carried out by the author, who was associated with one of the parties in the conflict, for his own benefit. A full description of the analysis is provided. A particular characteristic of the situation was that it was not possible to specify preferences for scenarios for any of the actors with a reasonable degree of confidence. This made the standard metagame analysis approach unworkable, and an alternative approach, involving the development of stories describing a variety of possible future events, was used instead
Author Correction: Long-range chiral exchange interaction in synthetic antiferromagnets
No full textIn the version of this Article originally published, the sentence ‘D.-S.H. wrote the paper with K.L., J.H. and M.K.’ in the author contributions was incorrect; it should have read ‘D.-S.H. wrote the paper with K.L., J.H., M.-H.J. and M.K.’ This has been corrected in the online versions of the Article
