Water 200 to 300 gallons. 



Use about 200 gallons of water for apple trees, 250 for plum trees and 300 

 for peach trees. When used upon peach trees, add i pound of lime to the mix-

 insecticide and fungicide, add 4 ounces to every 50 gallons of the Bordeaux 

 mixture.

 when an orchard is grass bound and growing very slowly, the trees are almost 



sure to suffer, and oftentimes, if neglected, will 

 be wholly destroyed.

 The presence of the larvae may be detected by the rough, dark and sometimes

 fine chips which they exude from their holes when quite young. A sharp
