3rd Application REMARKS 



Immediately after blos- 

 soms have all, or near- 

 ly all, fallen, and be- 

 fore the calyces close. 

 Use A3 or D, with 2 

 lbs. arsenate of lead. 

 This is the application 

 for codling moth. 



Cut out, disinfect and paint or cover with coal tar, 

 cankered areas on trunks and large branches. In 

 moist climates, or if the weather is wet or foggy, 

 give a 4th application with A3 or D or Scab about 

 two weeks after 3rd. See if aphids are present 

 just before leaf buds burst; if so, spray at once 

 with Black Leaf 40 or kerosene emulsion or whale- 

 oil soap. 



Cut out and burn blight as soon as seen, cutting al- 

 ways one foot or more below diseased areas. Disin- 

 fect tools after each cut. In moist or in foggy or 

 wet weather give a 4th application of A3 or D 

 about two weeks after 3rd. For Psylla, spray 

 thoroughly with Al or B just after buds burst, or 

 with Black Leaf 40 just after leaves open. For 

 slugs spray with arsenate of lead or dust fresh 

 air-slaked lime over the leaves. 



Just after blossoms have 

 fallen. Use A3 or D, 

 with 2 lbs. arsenate of 

 lead. 



Watch for black-knot and whenever seen cut out 

 well below diseased area and bum. If leaf blight 

 is troublesome, give a 4th application with A3 or D 

 as soon as fruit of cherry is picked. Destroy mum- 

 mied plums in autumn. Look for aphids just be- 

 fore buds burst, and if present spray at once with 

 Black Leaf 40 or kerosene emulsion or whale-oil 

 soap. Treat slug as on pear. 



About two weeks later. 

 Use A3 or D, with 3 

 lbs. arsenate of lead. 



If brown rot is likely to be troublesome use C again 

 about one month before fruit ripens. Destroy mum- 

 mied fruit in autumn. Remove at once and burn 

 any tree attacked by yellows or little peach and 

 also all suspected trees. Dig out borers at base of 

 tree with knife in May and again in October. For 

 shot-hole borer cut down and burn before April all 

 dead or dying trees or branches, and leave no brush 

 heaps near orchard. 



About one month after 

 fruit is set. Use C. 



Spray again whenever wet weather threatens. It 

 should always be done before, not after rain. At 

 first sign of powdery mildew dust with sulphur or 

 spray with C. For flea-beetles use poison when- 

 ever they appear. For leaf -hoppers or "thrips" 

 use Black Leaf 40 or kerosene emulsion oi whale- 

 oil soap in July to destroy nymphs. Clean cul- 

 tivation is very important, and destruction of all 

 old mummied grapes and prunings. 



Just after fruit sets. Use 

 D.
