Chinese rape, varieties of Brassica campestris and B. chinensis and many cruciferous crops including radishes, but except varieties of B. oleracea, are generally affected by a mosaic disease, causing serious losses amounting occasionally to a death rate of over 90%, while an infection rate of over 30% is not uncommon. The symptoms involved were vein-clearing, yellow or green veinbanding, typical mosaic, rugosity of leaf lamina, dwarfing and rosetting. They may appear in different combinations. Flower stalks...

Chinese rape, varieties of Brassica campestris and B. chinensis and many cruciferous crops including radishes, but except varieties of B. oleracea, are generally affected by a mosaic disease, causing serious losses amounting occasionally to a death rate of over 90%, while an infection rate of over 30% is not uncommon. The symptoms involved were vein-clearing, yellow or green veinbanding, typical mosaic, rugosity of leaf lamina, dwarfing and rosetting. They may appear in different combinations. Flower stalks may not come out or are shortened, deformed and twisted. Flowers appeared pale yellow and become abortive, or forming only small and twisted seed pod, which are sometimes spotted with black necrosis, and bearing small and deformed seeds. When the winter temperature is low, diseased plants may succumb first, forming missing hills. Late infections may result only in vein-banding of the upper leaves and partial abortion of the seeds. On several varieties of radish, mostly of the green type, which apparently are more resistant, only fine mottling appears on the leaves while infected. On varieties of B. napella, another oil-bearing group, the symptoms are entirely different (plate 1, fig. 5), appearing as systemic bright yellow spots on the leaves. Necrotic flecking can eventually be found at the center of these spots. Necrotic streaks and spots develop on the flower stalks and seed pods. Dwarfing and distortion occur on leaves, stalks and pods, and death may even be resulted from severe infections. However, this species showed certain degree of resistance to the disease in the form of late infection and the lower incidence of the disease. The viruses from different host plants are cross-inoculable, although some strains do not infect B. napella. None of them can infect the cabbage group by sap inoculation. 3 viruses were identified: differentiated by their physical properties and the host reactions they induced (Tables 1 and 2 for the viruses 1 and 2): 1. Thermal inactivation below 70℃. 2. Producing necrotic local lesions only on N. tabacum var, "Nungling 400" …… virus 1 2. Producing necrotic local lesions and systemic mottling on the same host……virus 2 1. Thermal inactivation above 90℃., necrotic local lesions on N. glutinosa…… virus 3 The first two viruses can be subdivided into 2 strains each by their ability to infect B. napella. Virus 1 is considered to be a strain of Brassica virus 2 or the Turnip mosaic virus; from the type, it differs in not infecting the cabbage group. Virus 2 is identified as a strain of Cucumis virus 1 or the Cucumber mosaic; virus; from the type, it differs in having lower thermal inactivation point (55℃.), lower dilution end point (1: 1,000—3,000); and shorter longevity invitro (2 days), in producing local lesions on tobacco, and in that the typical strain of Cacumis virus 1 gives only a partial protection to this strain on tobacco. The 3rd virus was less studied. It shows affinity to Nicotiana virus 1 or the tobacco mosaic virus. A limited test showed that the first virus was the only virus found present in the field in 1957. An analysis of 17 isolates of virus from the Chinese rape, exhibiting various syndromes of symptoms in the field, gave an Unanimous result in host reactions, indicating that these isolates belong to a single virus. Virus 1 was found to be easily transmitted by sap, by aphids, including peach aphid (Myzus pcrsicae), false cabbage aphid (Rhopalosiphum pseudobrassicae), and cotton aphid (Aphis gossypii). In insect relationship, the virus belongs to the nonpersistent group, a single feeding will enable an active transmission of about 20 minutes. Peach aphid seems to be an effective vector that 2 or more viruliferous aphids per plant are capable of 100% transmission. The virus is not seed-transmitted. Fresh residue of diseased plant in the soil may cause occasional infection of the replanted plants. The virus can infect several cruciferous weeds, but, among them, only Rorippa montana (wall.) Small grows all the year round and possesses a perennial crown. It is also foundto be commonly infected in the nature. Rubbing with infected sap or using aphid as vector, the virus from this weed can easily be transmitted to the Chinese rape, producing the typical mosaic symptoms. This weed, therefore, seems to be capable of beoming a source of inoculum for the primary infection of the Chinese rape.

南京及华东地区的油菜与十字花科蔬菜普遍发生花叶病。病原病毒經抗性(失毒温度、稀释終点、体外保毒期)測定和寄主反应測定,认为可以分作三大类型:分别为芸苔病毒2号,黄瓜病毒1号与烟病毒1号的株系。前两种病毒都能为害油菜、大白菜、白菜、芥菜、蘿卜等,但不为害甘蓝型的蔬菜,并都能引起菠菜和茼蒿的花叶,和在烟上引起局部枯斑。第一型在烟农特400号和心叶烟上不引起花叶,而第二型在烟和心叶烟上都能引起系統性花叶。第一型不为害心叶烟,而第三型可在心叶烟上引起小枯斑。第一型与凌立、楊演的油菜花叶病毒相近似,而和范怀忠、柯冲从十字花科蔬菜中所分离出的分离物1号最为相象。与裘維蕃、王祁楷在白菜上所发現的孤丁病毒的差别,在于不能侵害甘蓝类的蔬菜。第二型病毒与范怀忠、柯冲的分离物3号相近似,但与典型的黃瓜花叶病毒仍具有一定的差异。这些病毒在油菜上所引起的症状却沒有明显的差別。1、2两个类型的病毒都有一部分能为害早生朝鮮型的油菜,引起系統性黄斑及枮斑,病重的也能早期死亡。大田中的油菜病株的病毒,大多属于第一型病毒。病毒主要由桃蚜和蘿卜蚜传染,病毒系非持續性的,蚜虫一次吸毒后,传病期不超过20分钟。两个以上的桃蚜传病率就可达100%。种子...

The peach leaf hopper, Erythroneura sp., is one of the important insect pests of thepeach tree in Kiangsu Province. There were four overlapping generations a year. Theoverwintering adults became active in the middle of March, and migrated immediately tothe peach trees as soon as the young leaves sprouted out. They could not develop on theleaves of broad bean, cabbage and radish. The appearance of adult stage of each generation was as follows:The overwintering adults hid among several evergreen trees such as Juniperuschinensis var. Kaizuca Hort., J. chinensis L., Biota orientalis (Linn.)., Cryptomeria japo-nica D. Don., Pinus massoniana Lamb., Myrica rubra Sieb. et Zucc. It was found thatabout 30% of these adults survived even at a low temperature of --20℃ in late Feb-ruary. Chemical control experiments were carried out both in the laboratory and in theorchards. The results indicated that the malathion miscible oil (25%) at the dilution of1:1,000--2,000 was the most effective spraying formulation, which gave 100% mortalities4 hours after treatment, while 30% parathion and 50% ethion (1240) at the dilution of1:1,000 and 1:500 respectively also gave satisfactory control and exhibited comparativelylonger residual effects. The DDT miscible oil (25%) at the dilution of 1:250 was alsoeffective for controlling this species, which gave 100% mortalities 24 hours after spray-ing in the orchard, and showed the longest residual effect.

桃一点叶蝉在长江流域为桃的重要害虫,据在南京、徐州、洞庭东山等地调查,为害桃的叶蝉共有4种即:桃一点叶蝉Erythroneura sp.,小绿叶蝉Empoasca flavescens,大绿叶蝉Cicadella viridis及棉叶蝉Chlorita biguttula。以桃一点叶蝉为主。它的主要寄主是桃,其他尚有杏、李、中国樱桃、贴梗海棠、月季、苹果、梨等。桃一点叶蝉在南京一年发生四代,以第四代成虫在常绿树如龙柏、侧柏、柳杉、桧柏、马尾松、杨梅上越冬。至早春桃现蕾萌芽时,从越冬寄主上大部分直接迁飞到桃上,少量可到其他寄主上,4月以后都集中到桃上,直到晚秋开始作越冬之迁飞。至11月中下旬全部迁到常绿树上越冬。 室内药效测定结果:25%马拉松乳剂,30%E-605及25%DDT乳剂效果最好,41%敌百虫效果不好,效果最差的是10%γ666乳剂。两次田间防治试验结果与室内一致。在桃园内为避免经常使用DDT而引起螨类的大发生,可采用马拉松,E-605来代替或与DDT混合使用防治桃一点叶蝉及其他桃树害虫。

During 1959-1960 tests were made of the suscept range of the sweet potato wilt organ-ism,ps.batatae Cheng and Faan.Twenty-seven species of plants belonging to 12 familieswere artificially inoculated.The results show that potato (Solanum tuberosum L.),tomato(Lycopersicum esculentum Mill.),pepper (Capsicum frutescens L.),eggplant (Solanummelongena L.) and wild tobacco (Nicotiana glutinosa L.) are susceptible.This is in agreementwith the opinion of sweet potato growers in various localities and the experimental result ob-tained by Hwang and his coworkers in Kwangsi.They claimed that,with the exception ofwild tobacco which is not a crop plant,all the other 4 plant species are natural suscepts ofthe disease.The authors of the present paper suggest that these plants should not be used asrotation crops.The other 21 species of plants belonging to 12 families including Chinese radish (Raphanussativus L.),pumpkins (Cucurbita moschata Duch.),tobacco (Nicotiana tabacum L.) and Moon-flower (Calonyction aculeatum House) which are considered by the Kwangsi workers and bysome farmers to be natural suscepts of the disease were found to be immune to the disease.These plants are as follows:—Araceae:Colocacia antiquorum Schott;Amaryllidaceae:Alliumfistulosum L.and A.sativum L.;Compositae:Helianthus annuus L.and Zinnia elegans Jacq.;Cruciferae:Raphanus sativus L.,Brassica juncea (L.) Cossm.and B.alboglabra Bailey;Con-volvulaceae:Calonyction aculeatum (L.) House and Ipomoea hederacea (L.) Jacq.;Cucurbita-ceae:Cucumis sativus L.and Cucurbita moschata Duch.;Euphorbiaceae:Ricinnus communisL.;Gramineae:Zea mays L.;Malvaceae:Gossypium indicum L.;Papilionaceae:Arachis hypo-goea L.,Vicia fabae L.,Glycine soja (L.) S.and Z.and Vigna sesquipedalis Fruwirth;Pedaliaceae:Sesamum orientale L.;Solanaceae:Nicotiana tabacum L.var.Havana 38 andDatura metel L.

1959—1960年,对甘薯细菌性枯萎病菌(Pseudomonas batatae Cheng andFaan)的侵染专化性进行了试验。供试的植物共12科27种。人工接种试验结果:除甘薯外本菌还能侵染马铃薯、番茄、辣椒、茄子和心叶菸等5种植物,和雨广很多病区农民所反映的情况以及黄亮等在广西的试验结果相符合。其他12科21种植物包括黄亮等所认为是本病的寄主的萝卜、芥菜、菸草、月光花和南瓜等,经二次重复试验结果都不感病,初步说明它们不是本菌的寄主。
