Abstract
THE high atmospheric humidity in Scotland favours the rapid development of eyespot (Cercosporella herpotrichoides) on wheat and barley, but the severity of the disease is offso by the relatively long rotations employed. LS survey carried out in 1944 (Mary D. Glyline Ann Appl. BioL, 33, 1, 35; 1945) showed 75 per cent of the autumn-sown wheat crops to be affected, and some 9 per cent showed obvious loss. Nearly all spring-sown crops of barley were affected; but damage appeared to be less than on wheat. Sharp eyespot (Cortidum Solani) was widespread and was particularly common in Aberdeenshire; loss is apparently slight, but deep lesions may cause some straggling. Take-all disease (Ophiobolus graminis) was seen on less than half the wheat crops, and in only one case was 10 per cent of the straws affected. Except in Dumfriesshire and Aberdeenshire, it was much less common than eyespot, a conclusion similar to that reached by R. W. G. Dennis (Ann. Appl. BioL., 31, 370; 1944).
