Following a series of experiments conducted in East China Agricultural Re-search Institute (Nanking) during the past years,the "red arsenic",a well-knownraw-drug (containing approximately 90% of As_2O_3,9% of AS_2S_2 and 1% of mis-cellaneous substances),is found to be acceptable as seed disinfectant for the controlof cereal smuts.This raw-drug is not only excellent in effectiveness,but alsoeasily obtainable in this country. Incidence of infection of wheat bunt in the plots receiving 3 different treatments,namely,red arsenic (inoculated seed grains dusted at the rate of 0.05 % by weight),copper carbonate (0.3%),ethyl mercury phosphate (0.05%),during the last 4years,averaged 0.2%,1.4% and 2.7%,respectively against 44.8% in the control.The corresponding figures for the flag smut of wheat were respectively 3.1%,0.8%,5.0% against 20.5%; for the covered smut of barley,0.9%,1.1%,0.9% against1.6%; for the kernel smut of oats,6.8%,3.1%,0.5% against 41.4%.The resultsmake us believe that this native raw-drug is not inferior,in some cases even su-perior,to other fungicides now extensively manufactured and considered efficientin preventing the various cereal smuts.But in the control of the covered smut ofbarley,as we have already shown elsewhere,another native raw-drag,sulphur ismore effective.In the last 3 years,field experiments were carried out to studywhether arsenic gives beneficial effect on the germination of seed and on the yieldof grain.Arsenic was applied as dust to the clean seed wheat following thestandard hot water treatment.Data showed that the number of seedlings in asingle 12-ft.row ranged 368-400 from treated seed as compared with 362-386 fromuntreated seed.Yield of grain also increased 4.7 to 23.6 per cent.It is,there-fore,evident that this fungicidal dust,when properly used,is at least not injuriousto seed wheat.The following points,however,must be borne in mind when thearsenic treatment is put into practice: (1) The dosage should not be higher than0.05 per cent and lower than 0.005 per cent by weight of seed grain.Otherwise, ??it would be either injurious to seed germination or ineffective for disease control.(2) Arsenic can be applied only to thoroughly dried seed grain. Seed wheat con-taining 24% of moisture when treatment was made, lost its vitality in a very fewdays, while that with less than 12% moisture can be stored for one month withoutspoilage. (3) Arsenic reduced germination of seed grain after storage at the highertemperatures. Under laboratory conditions, seeds, treated during hot summer whenthe air temperature ranged between 31 and 35℃, largely lost their germinativecapacity within half a month, but seeds, treated in cooler season when air tempera-ture dropped below 22℃, germinated as untreated ones after being stored for 3months or longer. (4) The relative humidity during storage played the most im-portant role in causing arsenic injury to the seeds. Seeds of wheat containingproper moisture (around 12%) dusted with arsenic at correct rate (0.05% byweight), failed to germinate after being stored for 5 days at temperatures above30℃ under 100% r.b.; but there was little or no injury after a storage period ofover 7 months at 37℃ under 18% r.h. (5) The length of storage period is alsoa factor in causing arsenic injury, and at the same time affecting the efficiency ofthe treatment. Seeds dusted with arsenic at a dosage of 0.05% during mid-summer(July of 1953) retained their germinative capacity within 0.5 month, but no seedsgerminated after 2.5 months' storage. On the other hand, almost complete controlof disease was obtained from thoroughly infested seed grain dusted with 0.0125%of arsenic and stored for 60 days, but similarly treated seeds which were sownimmediately, gave 45.15% infection as compared with 72.77% in the check plot.Consequently, the proper method of using arsenic against cereal smuts is to dustthoroughly dried seed grain at the rate of 0.05-0.0125% by weight and to storetreated seeds under cool (below 25℃) and rather dry (around 80% of r.h.) con-ditions for a period of about one month. According to the results obtained from experiments conducted under bothlaboratory and field conditions, it is found that there is no synergism nor antago-nism between arsenic and such filling materials as ashes, slake lime, talc, charcoalpowder, and calcium phosphate; and that neither soil temperature nor soil moistureact as factors influencing the germination of treated seeds.

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。

Occurrence of Ustilago tritici on the improved varieties of spring wheat is a serions problem in Manchuria.The use of modified hot-water treatment in the early spring is more or less limited on account of the enormous quantity of seeds and the short period of sowing time.For this purpose,the hot-water treatment of the seeds in the fall and to store over the winter after being perfectly dried is suggested. Experments are held in the laboratory and greenhouse,as well as in the field. The treated and untreated seeds are stored under various environmental conditions at different periods of longevity.A final measurement between treated and un- treated seeds is made. The results obtained from 1953 to 1955 indicate as follows:Generally,under normal dry conditions of more than five months' storage,there is no difference between treated and untreated seeds in the percentages of germination,rates of emergence,heights and dry weights of seedlings,and yields.However,under conditions of high relative humidity,the treated seeds would be deteriorated in the same manner as the untreated ones.Although the results point out that the treated seeds tend to delay the emergence of seedlings from soil,yet,it does not influence the later growth of the wheat plants.Varietal difference between the treatments in the experiments is insignificant. The tentative results lead to a conclusion that the seeds of spring wheat varieties to be treated in the fall and stored in the winter may have a practi- cal value in Manchuria.

1.经二年的试验证明,小麦种子经冷水温汤浸种后,充分干燥,在普通干燥室内贮藏达5个月以上,其发芽、出土、苗期生长及最终产量均不受影响。2.在潮湿情况下贮藏,种子的出土率即迅速降低。但温汤浸种后的种子对湿度的感应与一般种子无异。3.参加试验的三个东北地区小麦推广良种对于浸种与贮藏关系上所表现的反应一致。4.贮藏对温汤浸种的防病效果无影响。
