SUMMARY. 
Downy mildew is the chief cause of the recent poor crops of late 
cucumbers in southeastern New York. Anthracnose has also 
been destructive in some seasons. 
In 1896 the Station made an experiment which showed that the 
greater part of the damage from downy mildew can be prevented 
by spraying seven times with Bordeaux mixture. 
An experiment made in 1897 showed that when an entire field 
is sprayed the downy mildew can be wholly prevented. In this 
experiment a yield of 101,960 merchantable pickles per acre was 
obtained. 
In a second experiment in 1897, on early cucumbers, the yield 
was increased at the rate of 30,450 fruits per acre, having a weight 
of 12,405 pounds. eae 
During the season of 1898 codperative spraying experiments on 
late cucumbers were conducted in four different localities on Long 
Island; viz.: at Greenlawn, Deer Park, Smithtown Branch and 
Mattituck. In each case an entire field was sprayed. At Green- 
lawn the sprayed field contained 1.5 acres sprayed seven times with 
Bordeaux mixture (1-to-8 formula); at Deer Park, 2 acres sprayed. 
eight times; at Smithtown Branch, 2.15 acres sprayed seven times; 
and at Mattituck, 2 acres sprayed five times.
