414 REMEDIES.

REMEDY XO. 106. 



A. — All grasses, weeds, debris of hopvines, etc., in the hop- 

 fields and around the surrounding fences, roads, etc., should 

 be carefully gathered and burned as soon as possible after the 

 crop is gathered. There are many species of insects that feed 

 upon the hopvine and pass the Winter (hibernate as perfect 

 insects), taking shelter among grasses, weeds and hopvine 

 de])ris that are allowed to remain on the grounds and around 

 fences and roads that are located in or around the field. 

 Therefore the necessity of cleaning and Ininiing such shelter 

 as they require to pass the "Winter under. 



B. — All poles used the previous year in the hopfields should 

 be thoroughly scalded before using. (See Remedies Nos. 70 and 

 71, excepting that one pound of potash should be used for 

 every ten gallons of water.) 



C. — The necessity of scalding the poles arises from the fact 

 that I have found the hop aphis hibernating in crevices and 

 roughened portions of the poles. I have also found the Win- 

 ter eggs of a species of plant-louse, but cannot say at present 

 that they were the eggs of the hop aphis. 



1). — All willow poles should be scalded l)efore using. I 

 liavr t'oiiiKl the plant-lice infesting willows at the time the 

 poles were cut, feeding upon the hopvine. 



E. — I have also found the ova of red spiders on the hoj)- 

 poles, after being taken from the ground in tlie Fall season. 



F. — Cautiox. — I have found the hop aphis in several hop 

 fields this season (1888). One grower remarked that they 

 were liannless in this State. Do not de})end on such state- 

 ments ; prevent them from spreading, l)y all means in your 

 )»ower; otherwise you may have the same experience of the 

 hop-growers in some of the Eastern States, and also in Europe.
