Cotton seeds collected from plants infected by Verticillium ablo-atrum were used for the purpose of studying seed transmission of the pathogen. Although verticilliate conidiophores had been observed occasionally under low-power microscope on the surface of the seeds plated on PDA in 1955, yet isolations of the organism failed due to the interference of several contaminants. Seeds were delinted in order to diminish the possibility of interference from lint-born contaminants. The materials were plated on different culture media such as PDA, acidified PDA, cotton meal agar and rice agar. All these plates failed to show verticillium colonies. Among the fungi obtained in these plates, Fusarium, Alternaria and Colletotrichum were the most frequent. Since both Verticillium albo-atrum and other fungi were harbored within the same seed, the difference of growth rates might be considered as an important factor involved in the difficulty of the isolations: Cultures of V. albo-atrum and Fusarium sp. were transferred simutaneously to PDA plates to test their growth rates. The diameter of their colonies were measured after incubation for 12 days under 22±1℃. Those of V. albo-atrum measured 2.8 cm., while the average of the latter was 9,3 cm. Interference of the fast-growers might render a slow-grower such as V. albo-atrum to be masked in the observations and to be depressed in the isolations. A method was developed to avoid the interference. The fundamental procedures of the method are outlined as follows. 1. Plating and observation. (1) Cotton seeds being delinted with commercial surphuric acid in order to avoid the interference from lint-born contaminants. (2) Delinted seeds being washed in a flask covered with wire gauze for 24 hours under running tap water in order to get rid of bacteria. Absorption of sufficient water during washing activates the hibernating mycelium. (3) Seeds being plated on 1.7% water agar instead of nutrient agar in order to diminish the growth of the fast-growers such as Fusaria and Alternaria. The plates being incubated under 22±1℃. for 15 days. (4) The plates being uncovered and observed directly under low-power microscope in order to observe the fungi undisturbed. 2. Isolation and preservation of the Verticillium cultures. (1) Verticilliate conidiophores being located under low-power microscope. (2) The tip of a flamed needle moistened with sterile agar being introduced within the microscopic field in order to fish the spores under focus. (3) Spore suspension being made by washing the needle in a 5 cc sterile water blank. (4) Dilution plates being made by placing 1 cc of the spore suspension in a petri dish and diluting with 10 cc of cotton stem agar. (5) The plates being observed under low-power microscope after incubation for 5—7 days at 22±1℃. (6) Verticillium colonies being locatad and a bit of the margin of a colony being transferred to PDA slant. (7) The slant cultures being flooded with sterile liquid paraffin after incubation for 7—15 days at 22±1℃. The cultures preserved with liquid paraffin were able to keep alived for 2 years. Seeds collected from the infected plants in 1955, 1956 and 1957 were studied. The percentages of seeds carrying Verticillium observed in these years were 39.8, 5.92 and 9.5% respectively. One of the representative single spore colonies obtained was identified as V. albo—atrum. Inoculation and reisolation tests showed positive results. Inspection of cotton seed samples collected from eight co-op farms in Shensi Province in 1958 showing that the percentages of seeds infected by verticillium ranged 3 to 23% with an average of 12.3%.

The occurrence of latent infection of pathogenic fungi in apparently healthy organs of citrus trees was proved by the authors in their research work. The authors made isolations from apparently healthy tissues of the bark and leaves of citrus trees growing in orchards and culture pans time after time. The results of isolation indicated that latent infection widely exsisted in citrus trees and the fungi were large in number and variety. Sixteen different genera of fungi were identified. Among them were Colletotrichum gloeosporioides Alternaria citri,Mycos phaerella horii, Guignardia (Phoma)citricarpa, Phomopsis citri,Fusarium sp. ,Pestalotia sp.,Cytospora sp. ,Macropooma sp., and Diplodia netalensis.No latent infection of these fungi was found in citrus trees grown in glasshouses.Experiments were made by inoculating young citrus leaves with conidiospore suspensions of Phoma citricarpa and Phomopsis citri, the two most important pathogens separately. In both cases, it was found that minute semi-transparent spots appeared on the inoculated leaves and then disappeared without recurrence. The authors obtained the original fungi from reisolations, which proved the latent infection of these pathogens.The authors discussed the relationship between the latent infection of these pathogens and the approaches to its control. Emphasis was laid on the maintenance of tree vigor which was thought to be the fundamental measure to control latently-infectious diseases.

Besides Fusarium sp.a species of Phytophthora was frequently found as another important causal organism causing the die-back disease of yardlong bean in the suburbs of Guangzhou.The causal fungus was identified to be Phytophthora vignae Purss. Two methods of inoculation of Phytophthora vignae were made.One was by woundless inoc-ulation which showed that the pathogen infectonly members the of the genus Vigna.The other was by wound inoculat-ion,in which infectseveral genera including the seedlings and pods of bean,fruit of the eggplant,and the tuber of the potatowere infected.Otherplants such as soybean (Glycine Max(L.)Merr.),mung bean(P.aureusRoxb),Phaseolus angularis Wight,garden pea (Pisum sativum L.),broad bean(Vicia faba L.),cucumber (Cucumis sativus L.),pepper (Capsicum annum L.)were found to be immune. Using larger quantities of inoculum,none of the eight varieties ofyard-long bean tested was found to be resistant to the disease,exceptthe"resistant No.2"variety showed some degrees of resistance n pot trials,the result of using 90% Aliete as fungicide at 1:300 concentration gives a better control of the disease. Application of the fungicide soon after inocculation results in 90.81% control,while application 3 days before inoculation shows less effectivity.If application was made 24 hrs after inoculation,it results in 51.33% of control.

广州地区长豇豆普遍出现的“死藤”除了镰刀菌枯萎病外,疫病也是重要的病原。疫病病原菌经鉴定为Phytophthora vignae Purss。这一发现,对长豇豆抗枯萎病的育种工作具有重要的意义。Phytophthora vignae人工接种只危害豇豆属各个品种,但刺伤接种能侵染菜豆荚、茄子果实、马铃薯块茎;不能侵染大豆、绿豆、赤豆、豌豆、蚕豆、黄瓜、辣椒。在高菌量接种条件下,所参试的8个品种均不抗病,以“抗病二号”较好。盆栽药效试验以90%乙磷铝300倍液效果较好。喷药后即接种防效达90.81%。喷药3天后还有一定的效果,但接种24小时后再喷药,药效便可降低为51.33%。
