 blossoms have largely dropped and before the calyx cup closes. 

 Direct the nozzles so that the spray will be shot into the throat 

 of every blossom, or calyx cavity. 



Arsenate of lead is recommended as it is extremely poisonous 

 to the codling-moth worms and on drying is very evenly distributed. 

 If it is properly made, it is the most adhesive of spraying poisons 

 and does not generally cause burning of foliage. Bordeaux mix- 

 ture is recommended as the carrier of this poison. Arsenate of 

 lead should be employed in the proportions of two or three pounds 

 to fifty gallons of water, or of bordeaux mixture, if it is desired to 

 apply a fungicide. 



The False Tarnished Plant Bug 



The false tarnished plant bug, Lygus invitus Say, is responsible 

 for a diseased condition of pears characterized by the cracking 

 open of the skin in small spots and the formation of protruding 

 granular areas. Fruits seriously injured are usually much
