The Thirtieth Annual Plant Pathology Field Meeting
[ 173 ]
THE THIRTIETH ANNUAL PLANT PATHOLOGY FIELD MEETING
27- 28 July 1956 Over forty members attended this meeting in the Nottingham district. Accommodation was provided in the Halls of Residence of the School of Agriculture, University of Nottingham, Sutton Bonington. Members were welcomed by Prof. F. L. Milthorpe, and then shown agronomic studies of the development of the potato crop, after which Mrs N. McDermott gave an entertaining and instructive demonstration of the collection of potato varieties and the rogue and virus collections. The glasshouses of the Agricultural Sciences and Horticultural Departments were visited to see work on the effects of soil moisture and salt content on the growth and health of tomatoes; control of the development of raspberries, by manipulation of the temperature and photoperiod; studies of the competition between crop plants and weeds, both above and below soil level; plant nutrition, and various methods for measuring solar radiation. After lunch Dr Hudson described the plant growth rooms of the Horticultural Department, and members then visited demonstrations dealing with potato diseases and sprout depression, prepared by the Potato Storage Investigation Unit ofthe Agricultural Research Council; seed germination; aphis infestation of crops; choke of grasses and Mycosphaerella ring spot of crucifers. The morning of the second day was spent visiting the Lenton Experimental Station of Boots Pure Drug Company. The methods used in the laboratories, glasshouses and field for screening compounds for activity as fungicides, insecticides or acaricides were described. Members saw trials used to distinguish phytotoxicity from the symptoms on a variety of crop plants resulting from deficiencies of pairs of elements. In commercial scale glasshouses, experiments were in progress on various rooting media and irrigation methods for tomatoes and carnations. Here as elsewhere in the station members were impressed by the very high standards of cultivation which they saw. After lunch, Prof. C. G. C. Chesters took the chair at a meeting in the Botany Department of the University (see p. 164). In conclusion, Dr Hickman expressed the thanks of the visitors to all their hosts, to the speakers and to those who had arranged demonstrations, and in particular to Dr Pugh the local secretary for the very successful organization of the meeting which all had enjoyed.
