Paperback. Condition: new. Paperback. 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 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.

Paperback. Condition: new. Paperback. 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.

He received his Ph.D. from the University of Amsterdam in 1961, with honours, and joined the Wageningen Agricultural University as a plant pathologist.
