VI. General Discussion 347 



can cind other work not only for the diagnosis of our diseases but for 

 recommendations as to treatment. It must however be recognised clearly 

 that conclusions which hold in other countries do not always apply here 

 and that if we are to obtain accurate solutions of our problems, those 

 problems must be studied in the place where they occur. For example 

 it was believed, accepting Woronin's conclusions, that Moniliafructigena 

 was practically confined to apples and pears and M. cinerea to stone 

 fruits. It has been shown however that in this country M. frucligena 

 may produce cankers on plums and M. cinerea a blossom rot of apples. 

 Similarly conclusions arrived at in America cannot be relied upon to 

 hold true for England. 



Furthermore cultural methods of investigation have shown that there 

 are different physiological races of M. cinerea. Progress in mycology 

 will largely result from the development of cultural laboratory methods. 



Dr S. G. Paine {Imperial College of Science). 



This conference has evolved a very exalted idea of what a mycologist 

 should be and the knowledge he must possess— physics, chemistry, 

 botany, mycology, farming and so forth. Such an ideal is unattainable. 

 There is still however one other subject of which a mycologist should 

 have knowledge and that is bacteriology. Not only is the importance 

 of the bacteria as causal agents of disease in plants being increasingly 

 recognised, but the bacteriological technique is being more and more 

 extensively adopted in experimental mycology. A bacteriological 

 training is largely one in clean cultural method and such training should 

 take an early and important place in the education of every mycologist. 



Professor F. Keeble {Botany School, Oxford). 



We have heard many schemes from people partial to one or another 

 aspect of the problem which has been before us and this conference has 

 been of great value in bringing together and synthesising these schemes. 



There must be a directing body, a milch cow providing money. There 

 must be large research institutes carrying out fundamental investigations 

 and radiating from these subsidiary stations situated in commercial 

 growing areas and concerned with the actual crop problems. There must 

 be a light cavalry — advisors who will leave the untrammelled realms 

 of pure research and move rapidly over the field of action. There must 

 be county organisations, technical men who will formulate the problems 

 and ask help in their solution, and these county organisations are an 

 essential j)art in the whole. This staff of people in intimate contact with 

 the commercial growers will arrange demonstration plots and trial
