SPRAYING THE APPLE AND RESULTS OBTAINED IN 1913 55 



after the petals fall, and another spray added two weeks later 

 for control of apple blotch. The fourth spray should be applied 

 when the second brood of coddling moth begin to appear. This is 

 usually from July 20th to August 15th, and can be determined by 

 banding the trees and watching the development of the larvae w'hich 

 are found beneath the band. If a partial third brood appears, as 

 was the case last season, another spray later in the season becomes 

 necessary. 



Recoiiiineiide<l Spray Calendar. 



First or cluster cup spray: Bordeaux mixture plus arsenate of 

 lead, 4 — 6 — 2 — 50. (Four pounds blue vitrol, six pounds lime, two 

 pounds arsenate of lead and water to make fifty gallons) applied as 

 a coarse mist unjier 200 pounds pressure, just as the buds in the 

 clusters are separating. 



Second, or petal-fall spray: Lime sulphur (32 degrees beaume) 

 plus arsenate of lead, 1 1/^ — 2 — 50 (one and one half gallons of com- 

 mercial lime sulphur solution, 2 pounds arsenate of lead and water 

 to make 50 gallons) applied from above as a coarse driving spray, 

 under 200 to 250 pounds pressure, when three fourths of all of the 

 petals have fallen. 



Third Spray: Three to four weeks after the second spray of 

 the same composition and strength as the second spray. Delivered 

 as a fine mist unde:* high pressure. In case apple blotch is present, 

 this spray should be applied about 5 weeks after the second, and 

 should consist of bordeaux mixture plus arsenate of lead, 3 — 4 — 

 2 — 50, if the weather will permit. Bordeaux should not be used dur- 

 ing prolonged wet rainy weather. In this case, lime sulphur should 

 be used three weeks after the petals fall, and followed two weeks 

 later with bordeaux. 



Fourth Spray: Should be applied when the second brood of 

 codling moth begin to appear. If no fungus diseases are present, 

 this spray may consist of arsenate of lead alone 2 — 50. If a fungi_ 

 cide is needed, lime sulphur may be used of the same strength as 

 for the second and third sprays, except in the case oZ extremely hot 

 dry weather, when bordeai x should be substituted, (3 — 4 — 50). The 

 spray should be applied by a sweeping or stroking motion of the 

 rod, beginning at the end of the limbs, and following down to the 

 trunk, with the spray directed in and down. This will insure the 

 trunk and center of the tree being well covered by the time the 

 outside and top is finished. Wormy fruit occurs more often from a 

 poor application, than from poor or insufficient amoiint of poison. 



Two pounds of arsenate of lead, to fifty gallons is as good as 

 more, if the liquid is properly applied. Through not demonstrated 

 by experiments, there is every reason to believe that a dormant
