SPRAYING. ORCHARD iMPoRT- ANT FOR BETTER YIELD
By P G. Holdenl

tBy F. G.. HOldenJ
 At my request MT. R. R. Robertsonl of Ohio, well known authority on horticulture, has prepared the follow ing srraying program. which is. offered to the busy owner of the small orch ard:9
 Spray all fruit trees without regard to kind or variety with the dormant spray. The dormant spray should bel applied in the early spring before thei leaves start, special care being taken to cover every bit of the tree surfacel from the ground up. Much depends on the thoroughness of this application. With peach trees, the earlier this dor mant spray is applied the better it controls curl leaf. Some advocate late fall spraying as best for peach; For apple trees, the later in the spring the dormant spray is applied the better it controls green aphis, or bud lice, but care must be exercised to apply it before the leaves make much growth, as it will burn all leaf growth it reacn- es. If the dormant spray is thorough ly applied it is seldom necessary to ap- ply the extra bud spray that is often recommended for the control of aphisl and fungus.
 To prepare the dormant or scale
 
 sulphur to seven parts water; or if miscible oil is used. dilute according to directions. Lime sulphur is commer- cial preparation that can be purchased in any town or city.
 The first summer spray should be applied to apple trees after the blos- som falls and before the end, or calyx, of the little apple closes. Use the sum- mer spray, driving it well into the end of the little apple just formed. This should take care of the first brood Of coddIing moth, and greatly lessen the second brood. The coddling moth lays the eggs that hatch into the wormns that we find in the apples. The second summer spray should be put on in about three weeks after the blossom spray.
 1 f The last or third summer spray l should be applied as soon as the second 1 brood of coddling moth appears. The I time that the second brood of coddling moth appears can be determined only l by close ogservation. It may be as 1 early as July 1 or as late as August | TO- The busy farmer can usually safe l 1y aply this spray any time from the 1 11tI1 of July to the 10th of August. ] (Ask your county agent what date Is l best for your locality)
 1 At the time of the third summer 1 spray, if there are any indications of 1 fungus growth on the apples, such as 1 apple scab, blotch or sooty fungus, it
 might be well to use 2-2-50 Bordeaux | spray instead of the lime sulphur. ad- l ding the arsenate of lead, the same as l with the lime sulphur summer spray l However, on the farm orchard the ! lime sulphur spray will answer practi-
 cally all purposes.
 To prepare the summer spray, take | one part lime sulphur to 40 parts 1 water, to which has been added arsen- l ate of lead to make a per cent. solu- i ton.
 To make a i per cent solution of ! arsenate of lead. Dissolve one pound l of arsenate Of lead in as many gallons 1 of spray solution as there is per cent ! of arsenic oxide in the poison. To l Illustrate, if you see arsenate of lead 1 powder containing B per cent arsenic oxide, one pound of this powder will :! be sufficient for 8 gallons Of the solu- l tion; or if fl per cent arsenate of lead paste is used, one pound of the. paste will be sufficient for only II gallons o1 l the spray solution.
 In using arsenate of lead start stir ring or agftating the solution before l adding the poison. Keep the solution agitated until it is all applied or part ot 1 the arsenic oxide will be precipitatel l in the spray tank and the solution
 weakened
 If peaches are sprayed in summer use self boiled lime sulphur not the commercial kind. Write your expert
 ,lent station for directions for making self -boiled lime sulphur or ask you ! county agent.
 ?, Besides the dormant spray the c11err. tt'aeeds one summer spray just as tn

 cherry, using the regular summer solu 1 fior
