BETTER FRUIT 



Page Nine 



First Fruit Spray, Stone Fruits — 

 For Syneta beetle, leaf-spot of prune and 

 cherry, peach blight and mildew. 



In orchards where the white Syneta 

 beetle is present, and in such numbers as 

 to result in serious injury, lead arsenate 

 should be used for their control in this 

 application, but because there is an element 

 of danger in the use of regular commercial 

 lead arsenate on stone fruits, it is advisable 

 to add to each 100 gallons of spray 2 

 pounds of rock lime, carefully slaked and 

 strained or an equal amount of hydrated 

 lime. 



Where ptach blight and mildew are 

 troublesome this spray should always be 

 applied until under good control. 



Calyx Spray, Apple and Pear — For 

 scab and, on apples, the first codling moth 

 spray, and is very important. 



The addition of lead arsenate is gen- 

 erally advisable even on pears as an aid in 

 controlling late fruit worms, bud moth 

 and similar foliage and fruit eating cater- 

 pillars. This spray is an aid in keeping 

 mildew infections off new foliage. 



Where orchard trees are not in vigorous 

 condition due to lack of proper cultiva- 

 tion, soil fertility or good root conditions, 

 growers often meet with spray injury from 

 the lime-sulfur at ordinary dilutions ap- 

 plied at about this time, particularly where 

 earlier lime-sulfur sprays have not been 

 applied according to schedule. This is 

 apparently worse some seasons than others 

 due to climatic variations. 



Fifteen Day Spray, Apple and Pear 

 — Required in sections where scab is abun- 

 dant. Cannot safely be omitted in the 

 Willamette Valley. 



Where slugs have skeletonized the pear 

 foliage the previous year these pests may 

 be checked by adding lead arsenate in 

 this application. 



Thirty Day Spray, Apple and Pear — 

 An important codling moth application, 

 for which proper timing is essential. It 

 is applied at the time the moths are deposit- 

 ing eggs for the first brood worms. The 

 exact time for this spray will vary with the 

 season. If possible, a specialist should be 

 consulted, or the grower should inform 

 himself in regard to the essentials in timing 

 the application. 



On scab susceptible varieties this spray 

 can seldom be omitted in Western Oregon 

 without danger. Where spr.ay burn on fruit 

 is feared. Atomic Sulfur or self-boiled lime- 

 sulfur may be substituted for the ordinary 

 lime-sulfur. On varieties little subject to 

 scab this spray may often be omitted if the 

 previous sprays have been carefully applied. 



July and August Sprays, Apple and 

 Pear — Applied for the second generation 

 of the codling moth. 



The exact time for best results from 

 these applications is variable and best deter- 

 mined by specialists or from breeding cage 

 records. Occasionally the late August ap- 

 plication may be omitted on pears, but con- 

 ditions vary so much with seasons and dis- 



(A) Where pest or treatment refers only to apple or only to pear this is so indicated, by the letter 

 (A) for apple or (P) for pear, Immediately following the pest or treatment. 



*With d'Anjou, Howell, Comice and other tender-skinned varieties of pears and with apples sus- 

 ceptible to burn or russeting from regular lime-sulfvir, substitute Atomic Sulfur, 12-100, or the self- 

 boiled lime-sulfur.
