7. PINE TAR CREOSOTE EMULSION: 



Pine Tar Creosote 1 gal. 



Caustic Soda 2-3 lb. 



Water 11% gal. 



Dissolve the caustic soda in 2 gallons of water in a large vessel, 

 stir in vigorously the creosote, add 9 2-3 gallons of water, to make an 

 8 per cent solution and strain into spray barrel. Used for woolley aphis. 



8. RESIN STICKER: 



Resin 2 lbs. 



Sal Soda 1 lb. 



Water 1 gal. 



Boil in an iron kettle in the open for 1 V-2 hours or until a clear 

 brown liquid is obtained. This is sufficient for 50 gallons of spray. 

 Used with arsenic for cabbage and similar foliage. 



9. POISON BAIT FOR CUTWORMS: 



Bran or middlings 50 lbs. 



Paris green or arsenate of lime 1 lb. 



Molasses 1 gal. 



Mix the bran and poison thoroughly by shoveling over several 

 times ; dilute the molasses with sufficient water, so that when poured 

 on the bran and thoroughly mixed, a crumbling mass is obtained. 



Place about the plants at nightfall or under light pieces of board at 

 any time or scatter broadcast. 



10. PARADICHLOROBENZENE: 



Free the ground from weeds and trash and apply in a narrow band 

 around the base of the tree and about one inch from the trunk. Mound 

 over with 4 or 5 inches of dirt and pack with hoe or shovel. For trees 

 3 to 5 years old use % ounce and remove mound after 10 to 12 days. 

 For trees 6 years old or over use 1 ounce. Mounds may be removed 

 after four or five weeks. 



11. POISON BAIT FOR RODENTS: 



Potato formula — Cut sweet potatoes into pieces about the size of 

 grapes ; place 3 quarts of these cut baits in a pan or bucket and from 

 a salt shaker slowly sift over them % ounce of powdered strychnine 

 mixture with an equal quantity of baking soda, stirring constantly so 

 that the poison is evenly distributed. (Poison should be applied as soon 

 as potatoes are cut and bait should be put on while fresh.) 



12. LIME-SULFUR WASH FOR RABBITS: 



A good wash to repel rabbits from injuring young fruit trees may 

 be made by using one part of concentrated lime-sulfur solution to four 

 parts of water. This should be thickened with hydrated lime to the 

 consistency of white wash and painted on the trunk of the trees 

 to the height of one or two feet. 

 23. SPREADERS: 



It is often desirable to add some material to the spray mixture to 

 get better wetting and sticking. Boiled flour paste made up at rate 

 of 1 pound of flour to one gallon of water and used in 50 gallons of 

 spray material gives very good results. 



Casein-lime spreader is being prepared by a number of firms and 

 should be used according to their directions. This spreader gives good 

 results. 



Spreaders may be used to advantage in all sprays except the miscible 

 oils. 



SPRAYING POINTERS 



1. Use a machine of adequate capacity. 



2. If a power sprayer is used, consider weight, type of pump. 

 and simplicity of the engine and its gearing to the pump. 



3. Use the new spray guns if you have a power sprayer. The 

 2 1*8 to 3 horsepower outfits will cany two rods or one 

 gun and do efficient work. If it is desired to use two 

 guns the large 10 horsepower outfit should be used. A 

 pressure of at least 250 to 300 pounds should be main- 

 tained. 



4. Valves should be easily accessible and preferably of the 

 ball type. Packing should be easily replaced. 



5. Relief valves should be simple and reliable. 

 G. Propeller agitation is the most satisfactory. 



7. Get the best accessories. Cut-offs should be two-way and 

 quick in action. 



8. Nozzles should be of the angle type, of large capacity, with 

 a minimum number of parts. 



9. Spray to cover every part of the tree or crop. 



10. Strain your materials thoroughly. 



11. Have adequate water supply, preferably under pressure.
