Eeport of the Horticulturist op the 



very badly mildewed. The treatments with lysol aud formalin 

 in some instances seemed to have slightly checked the mildew on 

 the fruit. The combined treatment of Bordeaux mixture and 

 potassium sulphide had checked the disease, but the most favor- 

 able results appeared where_the potassium sulphide had been 

 used for very early and medium early treatments. 



Picking the Fruit. 

 The last spraying was made June 21. Messrs. King & Robinson 

 wished to market the fruit grcen,so on July G and 7 it was picked. 

 The mildewed fruit and perfect fruit were weighed separately for 

 each different treatment. In order to have an accurate basis of 

 comparison the yields are figured so as to give the average per 

 plant in each experiment. The results are so arranged in the 

 following table that the reader can easily compare the sam*^ 

 remedies in the different series. It must.be borne in mind that 

 Series I received seven sprayings beginning April 12, Series II 

 received six sprayings beginning April 23, and Series III received 

 five sprayings beginning May 5.
