TL;DR: The dry and warm conditions during both these months were the cause of great damage due to red spider and plant lice, and seedborne diseases caused at first a foot- and stem-anthracnose, but in August the disease spread over the leaves and pods, causing brownish spots that flow together and give a reduction of quality and in yield.
Abstract: The influence of environmental conditions on diseases of the bean (Phaseolus) were studied last summer on the field and at the laboratory. The diseases due to deficiencies of anorganic matter were accompanied by distinct symptoms during June and July, but later on could scarcely be recognized. The dry and warm conditions during both these months were the cause of great damage due to red spider and plant lice. The virus diseases which are transmitted by lastnamed insects, were very much spread, in particular„curlmosaic” (Phaseolus virus 1), „yellow mosaic” or „steengrauw” (Phaseolus virus 2?). „Stipple-streak” (Nicotiana virus 11?) was partly masked during the heat season, but showed in August characteristic redbrown „ringspot” on the pods. This virus disease has wrongly been taken for a bacterial blight. The haloblight, however, is seedborne and gave rise to a heavy attack e.g. on „Ceka” beans in August. In June and July the disease could hardly be discovered in the fields. Further some „rust”- and „foot” diseases have been studied, which are often troubled withUromyces appendiculatus andColletotrichum Lindemuthianum. It was shown thatAscochyta Boltshauseri andAscochyta phaseolorum, both seedborne diseases, caused at first a foot- and stem-anthracnose, which was of little importance in midsummer; but in August the disease spread over the leaves and pods, causing brownish spots that flow together and give a reduction of quality and in yield. The footrots due to Fusarium sp., Sclerotinia sclerotiorum and Botrytis cinerea eem also to increase during cool moist weather.

TL;DR: Inorganic Plant Poisons and Stimulants as mentioned in this paper by Dr. W. E. Brenchley is a good book, but the treatment is less suggestive, and the grip less firm than we had been led to anticipate.
Abstract: Miss BRENCHLEY has set herself a difficult task in attempting to deal with problems such as are indicated in the somewhat ambitious title of her book, and we confess to a feeling akin to disappointment after a perusal of the volume. The work is good as far as it goes, but the treatment is less suggestive, and the grip less firm than we had been led to anticipate.Inorganic Plant Poisons and Stimulants.By Dr. W. E. Brenchley.
