The Renewal of the Neglected Orchard 1563 



Spraying 



The spraying of the neglected orchard is done in the same way as 

 the spraying of orchards that are well cared for. The following spraying 

 plan, which is taken from Bulletin 283 of the Cornell University Agricul- 

 tural Experiment S::ation, is suggested for the apple: 



I. Dormant season before leaf buds open, but just as they are swelling: 



(a) Lime-sulfur as a contact spray for 



San Jose scale 32° to 33° Beaume 1-8. 

 Blister mite 32° to 33° Beaume i-ii. 



(b) Add arsenate of lead, 2 pounds to 50 gallons, to the lime-sulfur 



as a poison for bud moth and cigar case-bearer. 



II. After leaf buds open but before blossoms open, that is, when they 

 are just beginning to show some pink. Watch the weather and get the 

 spray on before rain falls, not after: • 



(a) Lime-sulfur, solution, 32° Beaume 1-40, or bordeaux 3-4-50, 



for apple scab (the fungus). 



(b) Arsenate of lead, 2 to 3 pounds to 50 gallons, added to lime- 



sulfur or bordeaux as a poison for bud moth, cigar case-bearer, 

 and cankerworm. 

 This application should never be omitted during cold, rainy seasons. 



III. After petals have begun to fall, beginning when about two 

 thirds have fallen. Have spray on before rains come. This is important. 



(a) Lime-sulfur, 32° Beaume 1-40, or bordeaux 3-4-50, for apple 



scab and leaf spot. 



(b) Arsenate of lead, 2 to 3 pounds to 50 gallons, used with lime- 



sulfur or bordeaux for codling moth, cankerworm, and bud moth. 

 This is the most important of all the applications. 



IV. Ten days to two weeks later. Before rain period. 



(a) Lime-sulfur, 32° Beaume 1-40, or bordeaux 3-4-50, for apple 



scab and leaf spot. 



(b) Arsenate of lead, 2 to 3 pounds to 50 gallons, used with lime- 



sulfur or bordeaux for codling moth and cankerworm. 



V. Eight to nine weeks after blossoms fall: 



Same as IV for late scab infections and late attacks of codling 

 moth. In most seasons this application is not necessary. 



If aphis appears, spray before leaves curl with whale-oil soap, i 

 pound to 6 gallons, or with kerosene emulsion diluted with 

 six parts of water, or use one of the tobacco extracts. 



SCRAPING THE BARK 



Some growers recommend the removal of the old bark. The purpose 

 of this is the destruction of insects that m.ay harbor beneath loose pieces.
