This test indicated that the "home mixed" fertilizer designated as '*A," 

 used at the rate of 500 ])ounds per acre was the most economical and 

 its use paid in comparison with land not fertilized. 



Spraying tests on orchard fruits are being continued. The object is 

 to determine the comparative value of the self-boiled lime-sulphur mix- 

 ture, the dilute boiled lime-sulphur and the Bordeaux mixture on apple, 

 cherry, plum and peach. These tests are being made at South Haven 

 and at Hart. 



The strawberry crosses made several seasons ago, were again fruited 

 and careful notes secured. Several kinds appear to be of value but 

 further testing is, of course, necessary. 



Several experiments are in progress but from the nature of the work, 

 it is not possible to make even a preliminary report as to results.

REPORT OF THE SOUTH HAVEN SUB-STATION. 



To H. J. Eustace, Horticulturist, East Lansing, Michigan : 



Sir: — I herewith make a brief report of the work done at the South 

 Haven sub-station for the year ending June 30, 1911. 



Variety tests of strawberries have been discontinued because the soil 

 on the station property is not at all desirable for strawberry culture. 

 This variety testing required considerable time which has been used 

 in making spraying tests on fruit trees, and study and observation of 

 lime and sulphur for spraying purposes. 



Extensive tests of the comparative value of Bordeaux mixture, self- 

 boiled lime and sulphur and the commercial diluted lime and sulphur 

 on apple, peach, pear, plum and cherry trees were planned in the spring 

 of 1910, but a failure of the fruit crop resulted in abandoning them. 

 Similar tests were started this spring (1911). Plans are made for ob- 

 servation of the codling moth. Fruit growers will be notified of the 

 bei^t time to spray for both broods. It is believed that the work will be 

 of great benefit to the fruit growers of this section and greatly appre- 

 ciated by them. 



There is a great need for better opportunities to do field experimental 

 work. The station orchards are not at all suited for good tests as there 

 are so many varieties and only a few trees of each. These varieties have 

 been reported year after year and it does not seem wise to continue it. 

 If the money spent on the care of these varieties could be spent for 

 field experiments, it is believed the results would be of much more 

 economic value. 



A large amount of the time of the superintendent has to be given to
