    Black shank of tobacco in the former Dutch East Indies, caused by Phytophthora nicotianae

    Jacob van Breda de Haan is known as the author of the name Phytophthora nicotianae n.sp., the causal agent of ‘black shank’, an important disease of tobacco. Who was he? Where did he work? What did he publish? He published in Dutch, 1896, in a Dutch colonial report series. Next question: what more on tobacco diseases was written in obscure, colonial Dutch documents? Another scientist, Thung Tjeng Hiang, better known as the first Wageningen professor of plant virology, presented two original papers in Dutch on ‘black shank’ with the word ‘epidemiologie’ in their title, 1931 and 1938. Therewith Thung was an early bird in plant disease epidemiology. The foundational paper by van Breda de Haan and two important papers by Thung are presented here in English translation. Both authors worked in the former Dutch East Indies, present Indonesia, the first on the island of Sumatera, the latter on that of Java. Both were in the service of tobacco planters; they had to solve immediate problems as fast as possible. In a pioneer situation, van Breda de Haan was confronted with a sudden seedling disease which devastated the tobacco seedlings in the seed beds and which, yes, could lead to ‘black shank’ in adult plants. Thung, working in a well-organized environment, had to prevent ‘black shank’ in the tobacco plantations. Both authors were successful in controlling disease by means of a combination of ecological intervention and chemical treatment. Whereas van Breda de Haan could only dream of genetic control, Thung could incorporate the use of a fairly resistant cultivar in his recommendations. The 1896 paper has epidemiological observations scattered throughout, without using the word epidemiology. The 1931 and 1938 papers are probably ‘firsts’ in the Dutch phytopathological literature having epidemiology in their title, one an early study in quantitative, comparative epidemiology and the other an early version of landscape epidemiology. The three papers are preceded by a sketch of tobacco cultivation in the former Dutch East Indies, describing the position of the two authors in the tobacco scene; they are followed by a long-due biography of a forgotten plant pathologist, Jacob van Breda de Haan.
    Epidemiological analysis of the damage potential of Pgt-Ug99 in Central East, North East Africa; Iran and Punjab (India)
    Nagarajan, S. ; Kogel, K.H. ; Zadoks, J.C. - \ 2014
    Indian Phytopathology 67 (2014)1. - ISSN 0367-973X - p. 26 - 32.
    In the Rift valley Epidemiological Zone that falls in the predicted Puccinia graminis tritici-Ug99 spread route from Uganda to India, is the presence of bi-modular annual rainy season, absence of a hot dry summer and the practice of two wheat growing seasons (the green bridge). This ensures the survival of Pgt in situ and the endogenous primary inoculum initiates the recurrence of the disease. While in the Indian Punjab Epidemiological Zone the exogenous primary inoculum of Pgt from the Himalaya to the plains of Indian Punjab gets subdued and at best builds-up traces of disease severity before the harvest of wheat. The Iranian Epidemiological Zone is similar to Indian Punjab, except that there is no monsoon and the exogenous inoculum of Pgt initiates stem rust development year and again. It is felt that Pgt-Ug99 lacks pre-eminence to threaten wheat production in the Indian Punjab.
    Crop Protection in Medieval Agriculture
    Zadoks, J.C. - \ 2013

    Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.
    Influence of the Arabian Sea tropical cyclone and the Western disturbance on the appearance of Puccinia graminis f. sp. tritici virulence Ug99-TTKSK in Iran in 2007

    Epidemiology of Puccinia graminis f.sp. tritici-Ug99 in the Rift Valley “Flyway” from Uganda-Kenya to Yemen
    Nagarajan, S. ; Kogel, H.J. ; Zadoks, J.C. - \ 2012
    Plant Health Progress (2012). - ISSN 1535-1025
    Dispersal of a new virulence of Puccinia graminis tritici (Pgt)-Ug99 from Uganda-Kenya to Yemen, over >1000 km, happened in four years. Geo-agro-ecology of wheat cultivation and the epidemiology of Pgt indicate that the Rift Valley is a natural conduit “flyway.” The widely prevalent “green bridges” favor survival and spread of Pgt. This part of the Rift Valley is one single epidemiological zone, and the annual Pgt build-up is from the endogenous inoculum.
    On the political economy of plant disease epidemics : capita selecta in historical epidemiology
    Zadoks, J.C. - \ 2008

    Food security has been and always will be a human concern. Food security has always been fragile, threatened by a variety of factors including plant disease epidemics. Several plant disease epidemics of the past lead to questions like: What happened? How did people deal with these epidemics? What were the social and political consequences?
    The potato murrain on the European continent and the revolutions of 1848
    Zadoks, J.C. - \ 2008
    Potato Research 51 (2008)1. - ISSN 0014-3065 - p. 5 - 45.
    The tale of the Irish Famine, 1845¿1849, following the outbreak of potato late blight, has been told repeatedly, but the parallel story of the Continental Famine, 1845¿1847, has not yet been recorded. The Continental Famine was caused by poor harvests of potatoes, due to the same late blight, but also of grain, due to frost, drought, rust, voles, inopportune rains, floods and hailstorms. The Continental Famine was enhanced by hoarding, speculation, and poor governance. Hunger was followed by infectious diseases. The demographic effects of hunger and diseases are difficult to disentangle. The number of excess deaths due to the Continental Famine cannot yet be determined with any precision, but clearly it approaches that of the Irish Famine. The harvest failures of 1845 and 1846 and the resulting famines came on top of rural pauperisation and urban discontent, and thus contributed to the revolutions of 1848 on the European Continent. The statement `an epidemic of potato late blight caused an epidemic of revolutions¿ is, perhaps, exaggerated but it contains a grain of truth.
