Sweet-potato wilt,a dangerous disease of sweet potatoes,has made itsappearance for more than 10 years in several districts of the south-easternKwangsi and south-western Kwangtung.During recent years it has been found tocause a heavy loss of sweet potato crop in these two provinces. Sweet-potato wilt is a kind of wilt disease which infects the fibrovascular ??bundles of the plant.It begins to infect the vine cuttings and those parts thatare in close contact with the sick-soil.The infected parts first show the water-soaked appearance and then extend upwardly,and eventually become blackenedand rotted.As a rule,ths leaves of the infected plants show an abnormal coloror pale yellow,and drooping appearance.In the meantime,the root tips of theadventitious roots of the vines lose their cortex and begin to lot.Wilting followsquite rapidly and finally the entire plant dies.If the disease infects the plantafter the potatoes beginning to form,it may extend throughout the vine and in-to the roots,causing the enlarged roots to show brown streaks and finally blackenedand rotted with pungent odor. The cause of the disease may appropriately be considered as due to bacteriaand Fusarium spp.Four types of bacteria,i.e.white smooth type,yellow smoothtype,white rough type and yellow rough type,are able to cause the disease.Atleast four kinds of Fusarium,i.e.white aerial mycelium type,white mycelium withred of a purple tint substratum type,pink mycelium with red of a purple tint sub-stratum type and without aerial mycelium type are responsible for the disease.Which is the main cause of the disease? Either bacteria or Fusarium alone or theboth in combination is able to cause the disease,further tests should be madebefore a definite conclusion may be drawn. The dissemination of the wilt organisms may appropriately be considered inthree ways,namely,(1) by infested roots and vines,(2) by sick-soil,and (3) byinsects,as the sweet-potato weevil (Gycas formicarius Fabr.).The former twoways of dissemination are more definite than the latter,however,further testsand observations should be made. According to the results of 2-years field experiments in Tsen-shi and Peh-liustations,it shows that different varieties of sweet-potato possess different resis-tance to the disease.Among several varieties tested,it is found that Tai-nung No.3being a promising one,because it yields very high and is highly resistant to thedisease and to the drought.Although it is occasionally found to be susceptibleto the disease in the experiment field of Tsen-shi and is more commonly foundin the experiment field of Lin-kwei.The second variety is Tai-nung No.46 dueto its high degree of disease resistance. The results of preliminary tests indicate that the method of reproduction byold vines would decrease both in disease resistance and in yield within the samevariety. From tests conducted in two different fields,i.e.one at dry land and the ??other in the rice field,it shows that the discrepancies were found in the occur-rence of the disease and also in the relation of the method of manuring to thepercent of infection. Dipping cuttings in different disinfectants did not show any significant results.There are discrepancies in both plowed and sunned field test and two methodsof setting the vines test.These may be due to methods of treatment,landand varieties used for experiment being different. According to the results of date of planting tests in Peh-liu,it indicates thatthe occurrence and the development of the disease are closely related to the highhumidity and the high temperature.These climatic factors affect the health ofthe early growth of the plant which in turn would increase the disease resistance.It is suggested that the most suitable date for planting sweet-potato in Peh-liu isin the first decade of August. In comparing the weather records of the three districts—Lin-kwei,Peh-liu andTsen-shi—in relation to the date of early and last occurrences of the disease,itshows that an average air temperature of 23.4-28.4℃ is most suitable for the oc-currence of the disease,and an average relative humidity of 80 per cent is alsoneeded for the infection of the disease.Based on these facts,we may say thatsweet-potatoes in Lin-kwei are capable to be easily infected by the wilt organisms.except the last date of the infection would be preceded 10-20 clays.Any otherregions with similar climatic factors,it is also very possible to be infected. According to the results of 2-years experiments and facts from surveys,sug-gestive control measures are proposed: (1) excluding the disease by regulationthrough the use of quarantines enforced by an inspection station empowered torestrict or eradicate diseased roots and vines to prevent them from becomingsources of infection in disease-free districts; (2) selection of disease resistant varie-ties in combination with cultural practices such as the use of more ash,suitableamount of lime and manure,and suitable date of planting to enable plants toescape or resist the disease.For the present time,we suggest that the use of Tai-nung No.3 in Tsen-shi and Peh-liu may meet the requirement,and promotingthe method of root reproduction in place of an old method of reproduction byrepeating vine cuttings from old vines can prevent the degeneration of the plantand decrease the infection of the disease.

甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之一),临桂試...

Anthracnose of kenaf (Hibiscus cannabinus L.) caused by Colletotrichumhibisci Pollacci has been a limiting factor of kenaf production in China.Thedisease was found to be seed-borne,both externally and internally.The efficacyof conventional methods of hot-water treatment against internal mycelium wasfound to vary with lots of seeds tested,and with the moisture content of seedsduring the time of and after presoaking.Complete control of the disease wasobtained by treating the seed at 50℃ for 15-20 minutes after presoaking at20℃ for 24 hours.The percentage of seed germination after treatment wasreduced to 70 as compared with 90 in the controls. In addition to hot-water treatment,steeping of seeds in an aqueous solutionof 0.5% Uspulum at 24-26℃ for 24 hours gave very promising results.Theseedlings developed from treated seeds were found to be more vigorous thanthose from the untreated ones,apparently due to the stimulating effect of thefungicide. Aqueous extracts of garlic (Allium satiuwn L.) were tried as seed disinfectant.Steeping naturally infected seeds in a 1-2% aqueous solution of dried garlicpowder at 24-26℃ for 24 hours checked the disease significantly,but the percen-tage of germination of treated seed was also reduced.The addition of glycerol,ethanol to the extract by 2% gave batter results. The fungus in the host debris in the field in Peking and other localities inNorth China were found in most cases to be unviable after 2 winters.Culturalpractices such as field sanitation,deep ploughing and irrigation after harvestwere found to be effective in disease control if clean seeds were used. During growing season,a mixture of.1 part oi phenyl mercury acetate to19 parts of hydrated lime applied as dust after rain gave much better controlof the disease than bordeaux mixture. Many malvaceous species,except Hibiscus sabdariffa L.,were found to beimmune from the disease.Considerable difference in susceptibility was notedamong different varieties of kenaf from various parts of China.The southernvarieties were as a rule more resistant than the northern ones as observed infield tests in Peking.

1.洋麻炭疽病种子消毒处理,由于洋麻的开花特性和內在菌的问題,一般不易达到徹底的目的。2.預浸的温度和时間,对于烫种的影响,实际上是預浸后种子的含水量問題。在一定温度下,延長預浸时間,不仅可以增加种子的含水量,并且可以减少种子间含水量差异的幅度,从而提高烫种的效果。种子在20℃预浸24小时、在50℃烫15—20分钟,效果比其他处理为好。3.有机汞剂浸种和植物杀生素浸种,同样获得了良好的结果。0.5%乌斯普隆水溶液、大蒜干粉1:50倍浸出液在24—26℃浸种24小时,防病效果在90%左右;惟大蒜浸液对于种子的發芽率有一定程度的抑制作用。4.遺留田问洋麻受病組織中的洋麻炭疽病菌,二个冬季后基本上丧失了生活力。秋耕冬灌可以加速病株殘余的腐爛,促进病菌生活力的消失。5.洋麻生長期中撒布赛力散:消石灭(1:19)粉剂,防病的效果优于波尔多液。6.洋麻品种中对于炭疽病表現不同的抗病性。南方型品种较北方型品种抗病。选育适于华北栽培的南方型洋麻品种是解决目前华北和东北洋麻生产问題的一个主要途徑。

Various factors affect the development of headblight of wheat caused by Gibbe-rella zeae (Schw.) Petch under field conditions.The present investigation carriedout in 1955 and 1956 at Nanking,Kiangsu province,was primarily concerned withthe development of spores of the pathogen and the amount of rainfall in relationto disease development.For the purpose of inducing epiphytoties of the disease,asusceptible variety of wheat to headblight was grown in the inoculated plots.Inoculation was made at the surface of the soil with mycelium cultured on wheatgrain shortly after planting,and an "artificial rain" by frequent spray of water tothe plants was supplied after heading.Investigations were made on the develop-ment and dissemination of ascospores and conidia of the pathogen,the seasonaldevelopment of the disease and the meteorological factors involved. Field observations showed that the headblight fungus on the soil surface inthe inoculated plots produced both kinds of spores with ths ascospores much morepredominant than the conidia.Perithecia and mature ascospores could be formedboth in the fall and in next spring through early summer under conditions ofadequate moisture and warm temperature suitable for their development.It wasindicated by trapping the spores in the air that the ascospores produced on thesoil surface were the chief source of inoculum for primary infection although theconidia formed on the infected spikes were equally important in spreading the di-sease in the field later in the season.The frequency and amount of ascosporesand conidia present in the air depended upon the height in spore trapping.Whilespores were found most frequently and most abundantly at a height of 17 cm.above the ground,much less spores were caught at heights of 33 cm.and up to117 cm.There was a tendency to decrease in the amount of spores with theincrease in height.A comparative survey of the spores in the air in the inoculated ??and uninoculated plots indicated that a great majority of spores could not bedisseminated very far from their source of production.This,together with thefact that comparatively more spoies were trapped on raining days,made it rea-sonable to consider splashing rain as the more important agent than wind forspore dissemination. The amount of inoculum existing in the soil and the rainfall were proved tobe the factors of utmost importance for the epiphytotic of the disease.In 1955,the average percentages of headblight for the inoculated plots with and withoutthe spray of water were 29.4 and 13.4% respectively,in comparison with the neigh-bouring fields where only very few infected heads were observed.In 1956,theaverage percentages for headblight in the four experimental plots:(1) inoculatedand sprayed with water,(2) inoculated and not sprayed,(3) uninoculated andsprayed,and (4) uninoculated and not sprayed,were 42.98,42.05,11.91 and6.26%,respectively.In these four corresponding plots,the average percentagesfor culm rot were 4.27,3.89,3.65 and 2.17%.Although there was no significantdifference in the final percentages of both headblight and culm rot between thesprayed and unsprayed plots either with or without inoculation,probably due tothe continuous heavy rain in the latter part of the wheat-growing season,yethigher percentages were always observed in the sprayed plots than in the un-sprayed ones throughout the period of disease development.Under conditions ofabundant inoculum in the soil and heavy rainfall,increase in percentage of head-blight could reach as much as 32% within a period of two days even when theplants were already near maturity.In 1955,a daily average temperature over20℃ was found to be favorable for the development of headblight,but observa-tions made in 1956 did not show significant effect of the temperature on thedevelopment of disease.
