(3(4):23-27)Investigations on Seed Treatment of Peanut for Control of Sclerotial Wilt
No full textThe peanut wilt caused by Sclerotium rolfsii Sacc was widely distributed over the peanut growing regions throughout this Island. Approximately 9-15% of the plant wilted in the field during July to September yearly. In order to improve the seedling emergance an effort was made, to find some dependable seed protectants which could be recommended for use with this crop. This paper presents the preliminary results on the effectiveness of severals seed protectants on the seedling emergance of peanut in compost, infested with S. rolfsii, in Taipei, Taiwan,
From the results of seed germination obtanied in greenhouse and field trials it was concluded that majority of fungicides used in this experiment were proved to be of some value and may be expected to improve the stands after treatment. Of the materials used, Spergon at 0.8 per cent and Agrosan GN at 0.8 per cent dosages by weight of seed showed the most promice while Arasan SF at 0.4 per cent the next.
The effect of Phygon. XL, Femide and Phygon at all dosages were not so significant in the greenhouse trial as compared with the field trial but in the condition of the former the percentage of seed germination tends to increase toward the higher dosage.
New Improved Ceresan retarded seed germination when its dosage is over 0.2 per cent but the percentage of seed germination tends to increase as its dosage decreased. Then in conclusion New Improved Ceresan would have its fungicidal value for this crop if lower dosage was recommended

Writing a Wikipedia Article on Cultural Competence in Health Care
No full textThis article describes how librarians created a Wikipedia article on cultural competence in health care to support the medical school’s curriculum. Wikipedia, often considered not as reliable as scholarly articles, continues to be popular. Rutgers librarians conducted a Wikipedia project to improve its content to benefit students. The importance of cultural competency in health care is widely recognized due to increasingly diverse patient populations. Medical schools integrate cultural competency in curricula to train students to be culturally competent. Therefore, this topic was chosen for the Wikipedia Project. It is hoped that health sciences librarians and educators will benefit from their experience

No full text為明瞭洋菇褐痘病病菌之生理性質及本病之有效防治方法而學行本試驗。玆將本試驗所得之結果摘要如下：
洋菇褐痘病菌在培養基上的生長優劣，以燕麥培養基為最佳，酵母抽出液次之，其餘順序為堆肥抽出液Czapek Agar，馬鈴薯洋菜，麥芽抽出液等培養基。增殖培養源以小麥為最佳，其次是玉米，但堆肥則不能生長。在溫度適應方面，以24℃生長最佳，對高溫之抗力甚弱，在55℃下乾熱4分鐘，或濕熱1分鐘即死亡。對不同pH值之生長差異，到對酸性之適應力較強，即至pH 4.4生長尚頗為良好，而對鹼性之適應力較弱，在pH 8.4時菌絲生長即甚微弱。
藥劑防治以Dithane A-40及Dithane Z-78為有效藥劑，Dithane A-40 1,000倍稀釋液防洽效果最佳，每坪地每天施用1公升，連續兩次，藥害輕，且藥效持續力亦較長，Dithane Z-78 600倍每坪地施藥一公升，3天施藥一次，連續三次，效果與Dithan A-40 1,000倍相近，但藥害大，小菇菇體變黃。
Experiments were made to determine some of the causal fungus of bubble disease and find an effective control method. The results are summarized as follows:
The mycellial growth of the fungus was found best on oatmeal agar and in decreasing order on compost extract agar, Czapek agar, potato dextrose agar, and malt extract agar. As for the grain media, the pathogen grow satisfactorily on wheat, and less so no corn. 25℃ was the optimum temperatures for mycelial growth, the fungus did not tolerate high temperature and was killed at 55℃ after 4 minutes and 1 minute respectively where expored to dry heat and wet heat. The pathogen growth reacted differently in various pH ranges. In general, it had a wide pH range for growth a considerable growth could occur at pH 4.4 but only very restricted growth occurred at pH 8.4.
Dithane A-40 and Dithane Z-78 were found effective in controlling the fungus. Less phytotoxicity and longer effect resulted from spraying 1 liter of dilute Dithane A-40 diluted 1:1,000 per pin on two successive days. Than with 3 application of 1 liter of dilute Dithane Z-78, 600X, per pin at three day intervals. Phytotoxicity was exhibited in the latter case by producing yellow mushroom buttom

No full text1．榖仁樂生溶液浸種一小時，其濃度爲0.05%時，可消滅稻熱病病菌；0.07%時可使胡麻斑病及馬鹿菌病病原菌致死。田間試驗結果本藥液浸種消毒，防除馬鹿苗病有顯著之效果。
2．根據病斑消毒試驗結果，0.3%濃度之藥液可消滅病斑組織內之病原，又用以噴霧稻株亦得相同之結果。
3．浸種藥液之濃度，不論0.07%或0.1%，對種子發芽均有良好結果，對幼苗生長情形，則標準區與處理區間無顯著之差異。
4．穀化樂生溶液浸種消毒較本省過去所用之Uspulun或甲醛溶液爲簡便，因藥劑用量少，浸潰時間短是其長處。1. Granosan water solution was recommeded as seed disinfectant for the control of some seed-borne disesaes of rice. One hour of immersion at the concentration of 0.05 per cent was found effective for killing Piricularia Oryzae and of 0.07 per cent has also been productive of good result for controlling Helminthos porium oryzae and Gibberella Fujikuroi. While under field erperiment the latest ones produced the most significant benefit.
2. The internal mycelium of P. oryzae and H. oryzae were both killed as soon as the affected leaf lesions have been swiftly washed through the Granosan solution at the concentration of 0.3 per cent. Similar results were obtained by spraying on ”blast” affected plants.
3. Whatever the concentration of Granosan solution at 0.07 or 0.1 per cent all the treated seeds shown better germination without any toxical injuries

No full text本省大豆栽培事業年來由於農藝學者之研院及有關當局之倡導故栽培面積日趨廣大，為配合此項工作著者等曾於四十八年從事大豆病害調查，經獲悉若干病害甚為普遍流行，其中影響產量最大者，首推銹病，復據調查終果，目前在本省各地推廣之品種均遭感染，故於四十八年開始分別在花蓮屏東等地進行藥劑防治試驗，本試驗目的在於檢討供試藥劑之防病效果，適當撒藥時期及防治處理與大豆產量之影響。本試驗承蒙農復會惠予資助，使此項工作得能順利完成。本文先就花蓮區試驗結果作分析討論，試驗期中荷蒙花蓮區農業改良場許兩順先生鼎力協助，於此謹詰 謝忱。
Soybean rust caused by Phakopsora Pachyrhizi SYDOW is one of the destructive disease found throughout the growing areas. A spraying experiment for the disease control was conducted at Hwa Lien Experiment Station from 1959 to 1960 including three crops of soybean i.e. fall, spring and summer.
The purpose of the experiment is to determine the possible control with fungicides and their effectiveness as well as the timing of spray.
The fungicides used for this experiment were Ditliane M-22, Dithane Z-78, Dithane
Z-78 plus Wettable sulfur, 0-3818-B and Bordeaux, mixture which were applied at 7 days interval. A total of 5 applications of each testing fungicides were taken during the growing period. The first application varied differently wih the number of days after plantihg; they werethe 28th, 35th, 42th, and 49th respectively . Evidences indi - cated that the disease was well checked by either one of the fungidide which has been tested. The profitable time of the first spraying to control rust disease depended upon different crop of soybean. For protection of the spring crop, the first spraying should be initiated at the 35th day, but it is advisable to initiate the spraying program at the 49th day for both summer and fall crops. Yields of the crop were prominently increased except the fall crop which was insigniflcant because the weather was the limitting factor upon yields.
Among the testing fungicides, Dithane M-22 showed best effect to control rust disease while Dithane Z-78, Dithane Z-78 plus Wettable sulfur, Bordeaux mixture came next in order. 0-3818-B a new fungicide produced by Rohm & Haas Co., at the rate of 200 grams per 100 liters has its advantage of rust control, but it produced chemical injuries to the leaves after application. The phytotoxicity tended more serious as the rate of the chemical increased. For the best control soybean rust, it is suggested to apply either Dithane M-22 or Dithane Z-78 at the rate of 300 grams per 100 liters of water
