REPORT OP THE HORTICULTURIST. 59 



and because the dry weather of midsummer put a stop to the development 

 of the fungi, the results obtained from our experimental work in the line 

 of fungicides, were not as striking as would have been the case under 

 different circumstances; yet, in every case where there was any noticeable 

 amount of fungi, the application of fungicides had a good effect. The 

 best results however, were obtained at the South Haven substation, where 

 very beneficial results were secured in the treatment of peach leaf curl, 

 peach and plum rot, grape mildew, raspberry anthracnose, strawberry 

 leaf blight and the diseases of the currant, gooseberry and quince. 



Early in the season arrangements were made with a number of fruit 

 growers in various sections of the State for cooperative work with fungi- 

 cides, and although, for various reasons, the results were not as good as 

 might be desirable, the persons who undertooj?: the experiments and many 

 of their neighbors were so impressed with the value of the treatment that 

 they expect to spray thoroughly their entire orchards the coming season. 



As an indication of the use of fungicides, it may be said that while the 

 amount of copper sulphate used in the State for this purpose in 1892 was 

 less than 1,000 pounds, it increased in 1893 to at least five tons and from 

 present indications it is not likely to be less than twenty-five tons in 1894. 



The cheapest and most efficient fungicide found up to the present time 

 is the well known Bordeaux mixture, and as the arsenites can b^ more 

 safely applied when used in combination with lime, the use of the two 

 remedies, at one time, lessens the cost of application, and increases the 

 efficiency of both. 



As there were many calls for information on this subject, a portion of 

 bulletin 92 was devoted to this subject. 



The discovery of the cause of potato scab, and the remedy for it, seemed 

 to warrant some attention to learn the proper strength and duration of 

 time for the application. The experiment was so complete in all its 

 details that we shall be able to announce to the farmers a way of increas- 

 ing the value of the potato crop of the State from ten to twenty-five 

 dollars per acre at an expense not exceeding ten cents. 



The method of treatment found to be best is not essentially different 

 from that of Prof. Bolley, who first discovered the nature of the disease. 



FERTILIZER TESTS. 



The field tests of commercial fertilizers upon both fruits and vegetables 

 was continued about as in previous years. We also did something in the 

 way of cooperative work with these materials in different parts of the 

 State. This was done in order that we might learn whether commercial 

 fertilizers could be applied with profit to fruit crops. As the tests were 

 carried on in fruit growing districts, it also gave the neighboring fruit 

 growers an opportunity to judge for themselves as to the profitableness of 

 the application. 



VEGETABLE TESTS. 



The work of testing the novelties in vegetables sent out by the seeds- 

 men has been kept up, and the usual report will soon be issued. While 

 the number of novelties is rather less than in past years, it could be still
