84 STATE HORTICULTURAL ^SOCIETY. 



This work costs me $7 to $10 per year on a twelve acre field, and latterly 

 I have found very few borers. It is a practical remedy, as I have found 

 by experience. 



Mr, Hathaway: What effect has whitewash alone on the apple tree 

 borer? 



Mr. Davis: There is not much value in lime alone. Its use in the 

 formula is to keep the arsenic spread over the tree. 



Mr. Heiges: The best remedy we have found is white lead and boiled 

 linseed oil, mixed to the consistency of country cream (not the city sort), 

 to which is added one ounce of strychnine to the quart. Remove the 

 earth from the crown and paint the crown. This reiaedy is of proved 

 efficacy. It is more durable than mixtures of Paris green. As to the 

 cucumber beetle, turpentine in dry, unleached ashes or plaster, placed 

 about the vine (not upon it) will certainly repel both the striped beetle 

 and the black bug. The latter works upon the under side of the leaves, 

 and so it is of no use to put anything on top of them to kill him. To kill 

 the asparagus beetle, which is a very serious pest, cut off and burn the 

 matured growth. 



Mr. MoERiLL: called the attention of Prof. Davis to the San Jose 

 scale. Mr. Davis said it had only recently been discovered in the eastern 

 states, but already it is to be found in New York, New Jersey, Missouri, 

 and Maryland. It was first taken to New Jersey in nursery stock 

 from California, and these trees were sent into almost every state in the 

 Union. It is worse than all our other pests combined. In form it is a small 

 gray scale with brown center and reddish rim, and is perhaps one eighth 

 of an inch in diameter. There is a live insect under the scale. It first 

 appears upon the leaves and twigs and then upon the fruit. Watch care- 

 fully for it upon nursery stock. This scale does not travel very fast of 

 itself, but is likely to be sent everywhere with nursery stock. The remedy 

 so far known is fumes of cyanide of potassium applied under a tent cover- 

 ing the tree, but this can only be used in a limited way. Kerosene emul- 

 sion is of some service, but it takes a long time to subdue the insect in 

 that way. 



Mr. Packakd said he thought he had the small borer referred to by 

 Prof. Davis. The latter said it is known only in Massachusetts and Mich- 

 igan, appearing in an orchard, destroying some trees and disappearing. 

 Mr. Packard said he sent samples of the borer to Cornell, the agricultural 

 department at Washington, and to Michigan Agricultural college, and 

 received a different report from each. 



Mr. Heiges: I will send a bulletin on this scale to all who may desire 

 it. It is one of our worst pests. It may be found in lilacs, sometimes,
