new shoots developing on the wires are pinched off just beyond 

 the second node. 



During the past season two troubles have materially lowered 

 the yield of greenhouse cucumbers in New York State. Nama- 

 todes or eel-worms were very severe in many houses. The growers 

 have not practiced systematic sterilization, but nearly all of them 

 steam sterilized their soils in the fall. The other trouble which 

 has caused a great deal of loss is a new disease known as white 

 pickle. This new trouble has shown up especially in the Ironde- 

 quoit district. The effects are first found upon the fruit, it turn- 

 ing a lighter green color. Often the fruit becomes blotched in 

 appearance, which blotches sometimes show as warts. Both 

 small and large fruits are attacked. Later the leaves turn yellow 

 and die. This disease seems to be more prevalent with fall than 

 with spring cucumbers. As yet, nothing is known as to the cause 

 of this trouble, although it is thought to be contagious. There- 

 fore, the plants should be removed from the house as soon as they 

 become affected. 



Red spider, white fly and aphides have been very severe in 

 many cucumber houses. For red spiders the growers syringe the 

 undersides of the leaves with a strong current of cold water. For 

 white fly they fumigate with hydrocyanic gas at the rate of one 

 ounce potassium cyanide to four thousand cubic feet, and nicoti- 

 cide fumes efficiently control the aphis or green fly. 



The fruit is picked regularly every morning and marketed 

 locally. The earliest cucumbers in spring bring two dollars a 

 dozen. The price gradually goes down to a dollar or ninety cents 

 per dozen in May and June. 



Rochester growers figure on a yield of thirty-seven dozen 

 cucumbers per hundred square feet of area as a good average. 

 Many of the men secure better yields than this. 



tomatoes 

 New York State markets demand a red tomato. The Bonny 

 Best and the Peerless or Lord Roberts are the two varieties most 

 extensively grown. Some men have much better success with one 

 than with the other. The chief objection to the Bonny Best, 

 brought up by men who are successful with the Peerless, is that
