New Yoek Agricultural Experiment Station. 71 



The yield 6 per acre for the sprayed plants was at the rate of 

 71,000 fruits, weighing 25,265 pounds; for the unsprayed plants 

 at the rate of 40,650 fruits, weighing 12,860 pounds. Hence, the 

 increase in the number of fruits per acre due to spraying was 

 30,450 and the increase in weight 12,405 pounds. The sprayed 

 plants suffered considerably from anthracnose, but not at all from 

 downy mildew. 



EXPERIMENTS IN 1898. 



INTRODUCTORY. 



During the season of 1898 cooperative spraying experiments 

 on late cucumbers were conducted in four different localities on 

 Long Island; viz.: at Greenlawn, Deer Park, Mattituck and 

 Smithtown Branch. In each case an entire field was sprayed. 

 At Greenlawn the sprayed field contained one and one-half acres, 

 sprayed seven times; at Deer Park, two acres, sprayed eight times; 

 at Mattituck, two acres, sprayed five times; and at Smithtown 

 Branch, 2.15* acres, sprayed seven times. 



THE TERMS OF COOPERATION. 



The Station bore all expense of spraying and directed how and 

 when it should be done. The owners of the fields experimented 

 upon performed all of the operations connected with growing,, 

 gathering and marketing the crop according to their own judgment 

 and at their own expense, and carried out the spraying under the 

 direction of a representative of the Station. 



Therefore, the Station is responsible for the spraying only, and 

 does not commit itself to the recommendation of any of the cul- 

 tural methods employed on these experiment fields. 



THE SPRAYING OUTFIT. 



The spraying outfit used consisted essentially of a two wheeled 

 cart which carried a spray pump mounted in a 50-gallon barrel 

 and fitted with two leads of hose twenty feet long. Three men 



6 These yields are not comparable with the yields in the preceding experi- 

 ment because the fruits were allowed to attain greater size.
