894 EXPERIMENT STATION RECORD. 



kaiuit, sulphate of copper, lime, aucl corrosive sublimate showed that 

 each was capable of reducing to some degree the amount of disease, 

 but the best results were obtained upon the plat where snlphur was 

 used at the rate of 625 lbs. per acre. It is suggested that instead of 

 applying the sulphur broadcast a smaller amount might be successfully 

 used by mixing the sulphur with 5 times its bulk of fine earth, and 

 dropping a spoonful of the mixture in each hill before setting the i)lants. 



Exiierimcnis with leans (pp. 283-292). — These experiments, which 

 were in continuation of those reported in Bulletin 108 of the station 

 (E. S. E., 6, p. 996), were conducted principally with a view of testing 

 methods for the prevention of bean anthracuose. A review of the 

 results obtained in 1894 is given. The results of 1895 show that 

 ammoniacal copper carbonate did not prove as eflicient as Bordeaux 

 mixture when half strength solutions were used. The experiments 

 with eau celeste gave good results, followed closely by those in which 

 a neutral solution of copper sulphate was used. Sulphid of potassium 

 gave no indications of fungicidal properties when applied to beans. 

 The third crop upon the same land showed more than four times as 

 nnicli pod spotting as the first crop grown at the same time upon 

 adjoining new land. 



A test was made of the efl'ect of irrigation upon beans, in which it 

 was shown that while the yield of good i)ods was more than doubled 

 the yield of diseased jiods were increased fourfold. Mulching with 

 diseased pods of the previous crop greatly increased the amount of dis- 

 eased pods produced. 



Ex2)enments with tomatoes (pp. 293-296). — Plat experiments were con- 

 ducted with tomatoes in continuation of those reported in Bulletin 108 

 of the station (E. S. R., 6, p. 995), in Avhich numerous fungicides were 

 tested for the prevention of diseases of tomatoes, the i^riucipal of which 

 were leaf spot {Septoria lyvopcrsici) and anthracuose {Gloeosporiiim 

 phomoldes). ISleither the experiments of 1894 nor 1895 gave striking 

 results for any of the fungicides. This may be due partially to the 

 fact that the diseases were not very prevalent on any of the plants 

 either year. Bordeaux mixture reduced the fruit decay about one-half, 

 while copper sulphate, eau celeste with and without soap, and potassium 

 sulphid, were worthless. 



Experiments with peppers (pp. 297-299). — Experiments for the pre- 

 vention of anthracnose of peppers were begun, but the disease was 

 present in such small amount that the results did not indicate the 

 sui)eriority of any fungicide. 



The favorable effect of irrigation on jieppers was shown by largely 

 increased yield and a greatly prolonged period of fruitfulness. 



Experiments with eggplants (pp. 299-302). — Experiments were carried 

 on with sulphate of copper, Bordeaux mixture, eau celeste, and potas- 

 sium sulphid for the prevention of diseases of the eggplant, the prin- 

 cipal of Avhich are leaf spot and fruit rot. Of the fungicides tested 

 Bordeaux mixture gave the only satisfactory results. Mulching egg-
