When you spray, get a sprayer big enough — one that is adapted to your needs and that will do the work thoroughly. 



that gives a fine, foggy spray. Have the nozzle set 

 at an angle with the rod by means of a 45-degree L. 

 Use good sprayers, well equipped. Have every- 

 thing in good shape before you start. You can mix 

 the materials, if you want to; but if you have any 

 doubt whatever that you might not get the mixture 

 right, buy the ready-prepared lime-sulphur and 

 bordeaux that needs only the addition of water to 

 be ready for putting on the trees. Then follow the 

 printed directions faithfully. 



HOW TO SPRAY APPLE TREES 



No. 1. For San Jose scale. This spraying can 

 be applied any time after the leaves drop in the fall, 

 until new leaves come in the spring. But it is most 

 effective when apphed just before the buds begin 

 to push out in the spring. 



Use standard hme-sulphur solution, at a strength 

 of one gallon to seven to nine gallons of water. 

 (See manufacturer's printed instructions.) If bud- 

 moth and case-bearers are attacking the trees, mix 

 three or four pounds of arsenate of lead with each 

 fifty gallons of spray. 



No. 2. For apple-scab, canker-worm, bud-moth, 

 case-bearers, tent caterpillars, curculio, and leaf- 

 spot or frog-eye, spray after the cluster-buds open, 

 and before the blossoms open. Use standard hme- 

 sulphur solution at a strength of one and a haK 

 gallons to fifty gallons of water, adding two pounds 

 of arsenate of lead. If you want to make your own 

 material, always use seLf-boiled lime-sulphur for 

 this spraying. It is made by combining eight pounds 

 of hme and eight pounds of sulphur, with fifty gal- 

 lons of water, in the way described in "How to 

 Grow and Market Fruit." Two pounds of arsenate 

 of lead should be added to each fifty gallons of the 

 mixture. 



No. 3. The main spraying is for codlin-moth 

 (common apple worm), curculio, lesser apple worm, 

 and the second is for scab, leaf-spot and all the other 

 enemies mentioned under second spraying. Aside 

 from the San Jose scale spraying, this is the most 

 important one. Spray after most of the blossom 

 petals fall, and before the blossom cup or calyx 

 lobes close. Use either the commercial standard 



lime-sulphur solution at a strength of one and a 

 half gallons to fifty gallons of water, together with 

 two pounds of arsenate of lead, or seK-boiled hme- 

 sulphur and lead, strength mentioned before. 



No. 4. This is for added protection against 

 scab, codlin-moth, lesser apple worm, curculio and 

 leaf-spot or frog-eye. Apply the spray twenty to 

 twenty-five days after the blossom petals fall. Use 

 either commercial standard lime-sulphur solution, 

 at a strength of one and a half gallons to fifty gallons 

 of water, with two pounds of arsenate of lead, or 

 the seK-boiled lime-sulphur and lead. 



No. 5. This spraying is intended to control the 

 second brood of codlin-moth, also to help control 

 sooty fungus, leaf-spot and fly-speck. Apply it two 

 months after the blossom petals fall. Use the same 

 spray material you used for fourth spraying. 



SPECIAL ATTENTION SOME- 

 TIMES NEEDED 



If bitter-rot and sooty fungus are bad, you must 

 change spraying No. 5, and also give some later 

 sprayings, as follows: 



No. 6. Two months after the blossom petals fall. 



No. 7. Two to three weeks later. 



No. 8. Two weeks later. 



No. 9. Two to three weeks later. 



Use bordeaux mixture, made by dissolving four 

 pounds of bluestone in twenty-five gallons of water 

 and four pounds of Hme in twenty-five gallons of 

 water, then mixing the two lots. To this add two 

 pounds of arsenate of lead, except for sprayings 

 8 and 9, which are made with the bordeaux only. 

 If the weather is dry, the late sprayings may not 

 be needed. In wet weather give them all. 



If apple-blotch threatens to be serious, as judged 

 from former years, spray regularly at the same 

 dates as noted, but instead of lime-sulphur solu- 

 tion, use for sprayings 4 and 5 bordeaux mixture 

 made from three pounds of bluestone, four pounds 

 of lime and fifty gallons of water, with two pounds 

 of arsenate of lead added. Also apply an extra 

 spray, with the same material, six weeks after the 

 blossom petals fall.
