EFFECT OF CLOSTRIDIUM IN THE CONTROL OF FLAX FUSARIUM-WILT Taiwan Agricultural Research Institute
M. Chen; C.C. Tu; L.H. Jwo; 陳敏; 杜金池; 卓洛華.
[[abstract]]Bacteria were examined in two soils similar except that one was conducive while the other one suppressive to flax Fusarium-wilt. Bacterial flora differed markedly between these two soils. The former had a higher count of cocci and actinomycetes whereas the latter had a higher count of anaerobic bacteria and gram—negative rods. Several Clostridium spp. isolated from the suppressive soil were inhibitory to various formae of F. oxysporum including lini, pisi, niveum, lycopersici, and cubense race 1 and race T. In the pot test Fusarium-wilt was controlled by inoculating Clostridium sp. into moist soil kept at a neutral pH condition. 本研究之目的為比較亞麻立枯病(萎凋病)抑病土壤和導病土壤內細菌之分佈情形,並報導利用分離自抑病土壤之嫌氣性芽抱桿菌防治亞麻立枯病之盆栽試驗結果。導病土壤內以球菌和放射菌數量較多,而抑病土壤內則以革蘭陰性桿菌及嫌氣性芽抱桿菌居多。...

EFFECTS OF HOST VARIETY, PLANT MATURITY, SOIL TEMPERATURE, AND SOIL MOISTURE ON THE SEVERITY OF Macrophomina STEM ROT OF JUTE Taiwan Agricultural Research Institute
Yung-Hsiung Cheng; Chin-Chyu Tu; 程永雄; 杜金池.
[[abstract]]Stem rot, caused by Macrophomina phaseoli (Maubl.) Ashhy (Scierotium bataticola Maubl.), is one of the most important diseases of jute (Corchorus capsularis) and kenaf (Hibiscus cannabinus) in Taiwan. the organism is also known to cause root and stem diseases of many economic crops, notably charcoal rot of soybean (Glycine mix), corn (Zea mays), and sorghum (Sorghum Vulgare), and root rot of cotton (Gossypium hirsutum). The epidemics of Macrophomina diseases in relation to environmental factors has been discussed in some crops. Edmunds reported that no infection in soils, occurred when the available soil moisture was above 80%, but the infection, as evidenced by abundant sclerotial production, was so severe as up to 25%. Cotton plants subjected...

Seed and Root Exudations in Relation to Rhizoctonia Damping-off of Various Crops Taiwan Agricultural Research Institute
Chin-chyu Tu; 杜金池.
[[abstract]]The relation between plant exudates and soil-borne diseases is a challenging problem in the field of plant pathology. Barton (1) and other workers (2,3,4,5,67,8,9,10,13,) indicated that exudates from roots or other plant parts are attractive to parasitic organisms, or inductive to a growth response of pathogens that aids the infection process. Schroth and Snyder (11) proved that amino acids and sugars of bean exudates favorably influenced germination and growth of chiamydospores of Fusarium solani f. phaseoli in soil. Schroth and Cook. (14) reported that plant exudate was not specific to Fusarium spp. since spores of may other fungi germinated contiguously to seed germination of bean, and they evidently proved that incidence of pre-emergence...

Studies on the anastomosis groups of Rhizoctonia solani Kühn in Taiwan Taiwan Agricultural Research Institute
C.C. Tu; Y.C. Chang; 杜金池; 張義璋.
[[abstract]]Anastomosis among 264 isolates of Rhizocionia solani (=Thanatephorus cucumeris) indicated that 251 isolates fell into one of five groups (TRAG 1-TRAG 5) corresponding to groups previously descriebd by Ogoshi in Japan. Four of them (TR-AG 1-TRAG 4) were also comparable with those groups reported by Parmeter, et al in the North America, and Schultz and Richter & Schneider in the Europe. Anastomosis between isolates from the same group was perfect fusion, imperfect fusion, or contact fusion. No hyphal fusion was observed between isolates of different groups. Each anastomosis group seemed to have specificity in the host range, but this specificity was not rigid. Rhizoctonia solani Kuhn菌絲融合(Anastomosis)之方式有三:(1)菌絲尖端對菌絲尖端、(2)菌絲尖端對側生小枝(Telemorphic...

亞麻夜峨科害蟲發生種類調查 Taiwan Agricultural Research Institute
杜金池; 林祖輝; C.C. Tu; T.H. Lin.
[[abstract]]亞麻(Linum usitatissimun L)為本省重要纖維作物,其纖維特性為抗磨擦力大,不易起毛,導熱性佳,吸濕率小,拉力強,彈性大,適於製造帆布、漁網、線類、紙張等。其種子兼可製亞麻仁油,故為本省重要經濟作物之一。 亞麻在本省之栽培,早自1921年即由日本北海道引種栽植,中日戰爭後,臺灣在日本佔據下,以新興纖維資源作物而推廣種植。其栽植區域主要分佈於中南部之臺中、南投、彰化、雲林等縣,光復後,亞麻在臺中縣、彰化縣成為第二期水田之後作,歷年栽培面積均在3,000公頃以上。 近年來,亞麻之栽植,因害蟲之猖獗而形成無限困擾。亞麻受害蟲侵害後,發育受阻,產生分歧,纖維品質變劣,種子產量減少,是以引起各方之重視。臺灣亞麻之害蟲,據日人楚南仁博氏(1940)之調查,其種類包括直翅目(Orthoptera)半翅目(Hemiptera)鱗翅目(Lepidoptera)等共28種之多。其中最重要之害蟲,據筆者等之觀察,厥為鱗翅目夜蛾科之夜盜蟲(Lepidoptera : Phalaeuidae)。因此,亞麻夜盜蟲之研究及防治方法之探討,乃為亞麻增產上不可忽視之工作。 臺南棉麻試驗分所自民國51年起承 農復會補助經費進行本項調查。調查期間蒙 農復會植物生產組劉組長廷蔚之鼓勵與指導,前本分所技術員葉世煌先生,工礦公司亞麻廠之協助與幫忙,文成復蒙劉博士廷蔚,季分所長景元及臺南糖試所潘榮松先生之批閱斧正,同事歐陽聯成先生代攝相片,均此申謝。 By collecting larvae from the flax field to feed in the laboratory and capturing adult with light trap, Tainan T.F.E.S. has carried...

亞麻立枯病之種子傳播和種子處理試驗 Taiwan Agricultural Research Institute
杜金池; 程永雄; C.C. Tu; Y.H. Cheng.
[[abstract]]亞麻立枯病病原菌雖係土壤傳播真菌,但也可經由種子而萬播。採收自罹病亞麻田之種子質輕、不飽滿而略扁平、表面有皺紋、無光澤、千粒重為2.3~3.0g,依發病程度而異;反之健全田之種子較重、飽滿、黑褐色、表面平滑、有光澤、千粒重為3.6g。種子攜帶病原菌之比率為0.42~6.00%,與田間亞麻罹病率成正相關。病原菌亦可侵入種皮內,其比率為0.02~0.1%。以發病亞麻田(發病率26~50%)採收之種子播種會引起萌前腐敗,亦可導致發生幼苗立枯病,前者達15.7%,後者為7.6%。 亞麻種子以50% Benlate W. P., Benlate T-20, 50%Vitavax-Thi-ram W. P., 50% Bavistin W. P.等0.5~0.1%(依重量計算)行拌種處理,可有效防止病原菌之蔓延,但因亞麻種子表面有膠質,遇水黏結成團,處理工作不易進行。故採用Dowfumo MC-2 1.5 lbs/22.32m3行燻蒸處理,為既有效又經濟之方法。 Although flax wilt pathogen, Fusarium oxysporum f. sp. lini, is a well known soil-borne fungus, it can also be transmitted by seeds. Seeds harvested from diseased flax fields are lighter, yellowish to dark brown, rough and dull, weight per thousand seeds varied from 2.3 to 3.0 g depending upon the percentage of wilt flax...

亞麻立枯病抑病土壤駐在細菌對萎凋病菌之擷抗效能及田間防治效果 Taiwan Agricultural Research Institute
杜金池; 程永雄; 張義璋; C.C. Tu; Y.H. Cheng; Y.C. Chang.
[[abstract]]分離自亞麻立枯病抑病土壤之兼性嫌氣細菌(Bacillus sp.)對西瓜、香蕉及亞麻等不同分化型之萎凋病鐮刀菌均有不同程度之抑制作用。亞麻立枯病抑病土壤對各種作物之萎凋病也發現有抑病效果。網室試驗證明供試兼性嫌氣細菌9菌株和嫌氣芽抱桿菌2菌株個別加入土壤內雖均有抑病效果,卻以上述全部細菌混合後加入病土之抑病效果最佳,田問試驗將擷抗細菌混合液淋入田間土內,對亞麻生育初、中期之立枯病有防治效果,抑病期限約維持兩個月。 Flax Fusarium wilt-suppressive soil was proved to be also suppressive to banana and watermelon wilts. Nine isolates of facultative anaerobic Bacillus isolated from this soil were antagonistic to various form species of F. oxysporum on petri dish. Excellent disease control of flax wilt was obtained with application of these antagonistic bacteria into the infested soil in pot test. However, the control effect of these antagonistic bacteria lasted for only about 2 months in the field.

動力微粒噴霧器在棉虫防治上之施用價值 Taiwan Agricultural Research Institute
杜金池; 葉世煌; 游江海; C.C. Tu; S.H. Yeh; C.H. Yu.
[[abstract]]1. 本試驗之目的為探究動力微粒噴霧器在棉田治蟲使用上之實際價值,並以掛肩式圓筒全自動噴霧器之防治效力為對照。 2. 本試驗共分成(l)動力微粒噴霧器「慣用濃度」 (即19.5% Endrin E. C. 500倍) ; (2)動力微粒噴霧器「加倍濃度」(即19.5% Endrin E. C. 250倍) , (3)掛肩式圓筒全自動噴霧器「慣用濃度」(即19.5% Endrin E. C. 500倍)等3處理。 3. 動力微粒噴霧器與掛肩式圓筒全自動噴霧器之比較結果,就噴藥所需時間之長短觀之,前者比後者快速5~7倍,而使用藥劑稀釋用量,若棉株在50公分以下時,前者比後者減省50%;棉染60公分以上時,可減省藥劑稀釋液64~68%。 4. 在試驗3種不同處理間,害蟲被害率及籽棉產量均極相似。換言之,動力微粒噴霧器「慣用濃度」之防治效果及產量與動力微粒噴霧器「加倍濃度」或掛肩式圓筒全自動噴霧器「慣用濃度」之防治效果及產量間之差異並不顯著。 (1) The role of this experiment was to study the practical value of knapsack Atomizer on controlling cotton insects, as well as to compare the results of treat-ments applied with Detachable Compression Sprayer.

康乃馨品種間葉斑病之發生及防治 Taiwan Agricultural Research Institute
王貴美; 羅朝村; 杜金池; Kuei-Mei Wang; Chaur-Tseun Lo; Chisn-Chyn Tu.
[[abstract]]Alternaria dianthi Stev. & Hall引起的康乃馨葉斑病,是本省康乃馨栽培上主要的葉部病害之一。露天栽培的康乃馨葉葉斑病發生較簡易防雨設施者為嚴重。不同康乃馨品種在田間發生葉斑病之程度存在明顯的差異,其中以紅花品種較為抗病。溫室檢定50個康乃馨品種對葉斑病菌之抗感性,僅有8個品種抗病性較高,其餘均為感病或高感病品種。將抗病品種與感病品種採單株或單行混植,則有促使抗病品種產生病害的趨勢。溫室藥劑測試選出75%四氯異苯腈(Chlorothalonil)可濕性粉劑400倍及24.9%待克利(Difenoconazole)乳劑1,000倍兩種藥劑進行田間防治試驗,結果顯示,發病前或發病初期施用此兩種藥劑均可有效防治葉斑病的發生,其中尤以待克利效果最佳,並有顯著提高切花品質與產量的效果。

枇杷白紋羽病之傳播及防治 Taiwan Agricultural Research Institute
段中漢; 蔡武雄; 杜金池; C. H. Duan; W. H. Tsai; C. C. Tu.
[[abstract]]白紋羽病菌(Rosellinia necatrix)在本省已發現能感染枇杷、葡萄、梨、桃、蘋果及茶樹等作物。將這些不同寄主來源的白紋羽病菌製成麥粒菌種接種枇杷,於二至四個月內皆能使其萎凋、死亡。枇杷白紋羽病菌在田間之存活與傳播主要是依靠罹病的枇杷根,病原菌藉埋置土中的罹病根至少可存活三年以上。而田間雜草「香附子」在受到病原菌拓殖後亦可能有利於病原菌之傳播與存活。本病之防治首要挖除罹病植株的根部。經室內藥劑篩選及盆砵試驗得知,罹病跡地灌以貝芬替(Bavistin 50%WP)、免賴得(Benlate 50% WP)或邁隆(Basamid 85% WP)等藥劑之500倍液,再於土表覆以透明之塑膠布可得良好的殺菌效果。 White root rot disease caused by Rosellinia necatrix can make many plants wilt and die, particularly on fruit trees.

楊桃炭疽病菌之病原性及感染源 Taiwan Agricultural Research Institute
段中漢; 蔡武雄; 杜金池; C.H. Duan;W.H. Tasi;C.C. Tu.
[[abstract]]楊桃炭疽病(病原菌:Colletotrichum gloeosporioides)為臺灣地區楊桃栽培上最常見的病害。本病之病徵、病原菌形態、病原性及影響病害發生之因子,如溫度、感染源之來源等為本研究探討的重點。C. gloeosporioides係以分生孢子為感染源,分生孢子之發芽及附著器形成的最適溫度分別為16~36C及16~24C。病原菌以果實為主要為害對象,除造成果腐外,並於罹病部位大量產孢,成為次生感染源的主要來源。本菌可感染各齡期的果實;此外,亦可感染葉片,但無病徵顯現,呈潛伏狀態。田間楊桃葉片及其所著生之中軸常有病原菌存活其上,其帶菌率可達8~36%。至於存活在楊桃枯枝、落葉上的病原菌,亦有可能成為本病之感染源。如將這些帶菌的枝、葉置於田間,則其上的病原菌可存活約20日;但若置於有遮蔽之乾燥處,則其上的病原菌可有四至五個月的存活期。接種來自番石榴、檬果、木瓜、蓮霧、葡萄及香蕉等六種作物之炭疽病菌於楊桃,亦能使其果實罹病,故其亦可能為本病之感染源。
