October, using either bordeaux mixture 

 4-4-50, or lime-sulphur, summer strength. 



Treatment for bearing orchard: First, 

 spray with lime-sulphur, diluted to sum- 

 mer strength, just as the blossom buds 

 begin to separate in the cluster and show 

 color, or slightly before. This is the first 

 spray for apple scab. In case bud moth 

 or other leaf-eating insects are present; 

 add arsenate of lead in the proportion of 

 two pounds to each fifty gallons of spray. 

 If aphids are troublesome, add black leaf 

 or black leaf 40 as above. Second, spray 

 with lime-sulphur, summer strength, to 

 which two pounds of arsenate of lead has 

 been added to each fifty gallons, just 

 after the petals have fallen. This is the 

 second scab and the first codling moth 

 spray. Third, in orchards that are badly 

 infested with apple scab, spray ten days 

 or two weeks after the second spraying 

 with lime-sulphur, summer strength, or 

 with self-boiled lime-sulphur (8-8-50). 

 This is distinctly a scab spray, and in 



regions where scab is not prevalent may 

 be omitted. Where codling moth or leaf- 

 eating insects are present, two pounds of 

 arsenate of lead should be added to each 

 fifty gallons of spray. In those sections 

 of the state where scab is not present 

 and it is necessary to spray for leaf- 

 eating insects, arsenate of lead may be 

 diluted with water in the proportion of 

 two pounds to fifty gallons. Fourth, the 

 second spray for codling moth should be 

 applied at the time the moths are depos- 

 iting eggs for the first generation, or just 

 as the very earliest worms are beginning 

 to enter the fruit. In the greater portion 

 of the Willamette Valley this will be 

 usually between June 25 and July 1, 

 although the dates may vary somewhat 

 with the season. This date is also 

 approximately correct for most portions 

 of the Hood River Valley, but in South- 

 ern Oregon and the warmer parts of the 

 Grande Ronde Valley this application 

 should be made somewhat earlier. Use

two pounds of arsenate of lead to fifty 

 gallons of water. Fifth, an application 

 of arsenate of lead should be applied as 

 a preventive of injury by codling moth 

 about four or five weeks after the fourth 

 spraying. In the Willamette Valley this 

 will be about August 1. Sixth, soon after 

 the fall rains begin, or about October 1, 

 it is advisable to spray with summer 

 strength lime-sulphur as a preventive of 

 apple tree anthracnose. If bud moth has 

 been prevalent, add arsenate of lead in 

 the proportion of two pounds to fifty 

 gallons of spray. Seventh, as soon as 

 possible after the fruit is harvested, 

 spray with bordeaux mixture, 6-6-50, or 

 lime-sulphur, winter strength, as a pre- 

 ventive of anthracnose. It is also pos- 

 sible that this and the preceding spray 

 will have a beneficial effect in reducing 

 the spread of apple scab on the foliage 

 and fruit, which frequently is a serious 

 trouble in the fall in some sections of the 

 Northwest. The first, second and third 

 sprays for the pear correspond 

 to those recommended for the 

 apple, where the pear scab is 

 prevalent. If only codling 

 moth is present, then spray as 

 recommended under the sec- 

 ond, fourth and fifth sprays 

 for the apple. For the pear 

 no fall spraying is necessary, 

 except where the bud moth 

 is prevalent. In that case use 

 arsenate of lead, two pounds 

 to fifty gallons of water, from 

 September 15 to October 1. 



In treating the peach, first 

 spray with lime-sulphur, win- 

 ter strength, just as the buds 

 are swelling in the spring, 

 but before the terminal buds 

 show any green color. This 

 application, if made in a thor- 

 ough manner, will prevent 

 peach leaf curl and destroy 

 San Jose scale. This is the 

 most important single spray 

 for the peach. Second, if the 

 peach spot has been serious, 

 spray in spring after the fruit 

 is set with self-boiled lime- 

 sulphur, 8-8-50. (The time for 

 this spray is about May 10 for
