130 THE HOP 



worm. Many of them are easily destroyed in this way. 

 Others, however, escape, drop to the ground and begin 

 work at the crown. A generally adopted remedy at 

 this time is high hilling and fertilizing, which induces 

 the putting out of rootlets above the main root, en- 

 abling the vines to derive nourishment through this 

 channel when the stem has been gnawed through. An 

 experienced grower in Otsego county, N. Y., recom- 

 mends that at the first hoeing the dirt be care- 

 fully worked away from the vines by the hoe, leaving 

 them bare down to the bedroot. The weather tough- 

 ens the lower part of the stem and renders it unat- 

 tractive to the grub. Immediately after the hoeing, 

 a handful of composite, consisting of equal parts of salt, 

 quicklime and hen manure, mixed while slaking the 

 lime and left standing for two weeks, should be placed 

 about each vine root. 



CATERPILLARS FEEDING UPON HOP LEAVES 



Several different kinds of caterpillars feed on the 

 leaves of the hop plant during the summer, but they 

 are easily controlled and seldom do any especial dam- 

 age. Certain of these species may be illustrated and 

 briefly mentioned. All are readily destroyed by an 

 arsenical spray. Should any one of these insects 

 become sufficiently numerous to threaten damage, and 

 any of them is at all times liable to sudden increase, 

 the yards should be promptly sprayed with Paris green 

 or London purple, in the proportion of one pound to 

 150 gallons of water, or with arsenate of lead in the 

 proportion of two pounds to TOO gallons of water. 



THE HOP VINE SNOUT-MOTH (Hypena liumuli, Harr.) 



In 1856 Dr. Fitch, writing of this insect, considered 

 it to be the most universal and formidable of the hop 

 insects, making its appearance suddenly, and some- 

 times in a few days completely riddling and destroying
