354 EXPERIMENT STATION RECORD. 



diseases are reported. The plants experimented with were tomatoes, 

 turnips, potatoes, bush beans, peas, chard, Lima beans, and beets. 

 The ridoiiig- of the soil for the added exposure does not show an}^ 

 marked advantage. There was a slight gain in the amount of crop 

 with beets, bush beans, peas, and turnips, but an actual loss in case of 

 tomatoes, potatoes, and Lima beans. 



Experiments with sjmtying (pp. 402-404). — The formulas for the 

 fungicides used in the foregoing experiments are given and the details 

 of the experiments are briefl}^ reviewed. So far as opportunity 

 offered for comparison, the soda-Bordeaux mixture was about equal 

 to the Bordeaux mixture in its efficiency. 



Exjyeriments with soil inoculation (pp. 406, 407). — These experi- 

 ments were conducted with beans, peas, corn, Lima beans, cucumbers, 

 lettuce, and tomatoes; with the exception of the lettuce, as noted above, 

 there was little evidence that plant diseases can be transported by the 

 method pursued. 



Experiments with ornamental plants (pp. 408, 409). — Brief notes are 

 given on experiments with a immber of ornamentals, most of which 

 were almost wholly free from fungus attacks. 



Experiments with asjjaragits rust (pp. 410-413). — The author gives an 

 account of the present season's investigations in spraying as a pre- 

 ventive of asparagus rust in continuation of experhuents previously 

 reported (E. S. R., 11, p. 753). Bordeaux mixture was the only fungi- 

 cide used, and 5 applications were given during June and July. In 

 August a number of plants were noticed to be injured by the fungicide, 

 and half strength solution was used during August and September. A 

 difference of 16.9 per cent was noticed in favor of sprayed plants. 

 Observations made in the field seemed to indicate that the rust has not 

 proved as harmful to the asparagus industry as was first expected. 

 Clean culture and the use of (!ommercial fertilizers have tended to 

 produce a strong growth, so that the plants escaped serious injury. 



Exp)e)'ime7itx with pear hlight (pp. 414-417). — The third year's experi- 

 ments with pear blight are reported. The results agree with those 

 previousl}^ given (E. S. R., 11, p. 753), in that summer-pruned trees 

 yielded better than others, but there is little in the way of conclusions 

 to be drawn from the experiments thus far conducted. 



Brief notes are given on the forcing of peaches attributed to causes 

 similar to, if not identical with, peach yellows and on fungi as related 

 to weather. During the season covered by the report there was an 

 unusual precipitation in February and March, followed ])v a drought 

 in April and May. As a result there was but slight occurrence of 

 fungus diseases early in the season. 



Cultures of UredinecC in 1899, J, C. Arthur {Bot. Gaz.,'29 {1900), 

 JS\>. J/,, pp. '2GH-;i7(j). — An outline is given of studies made by the 

 author on the relationship between the tecidial and teleutospore forms
