SPRAvixa. 



EXPERIENCE has demonstrated the fact that Spraying at the proper time and 

 properly done for protection against destructive insects, rot, fungus and bhght, 

 is the best if not the only sure remedy against these enemies of the horticiil- 

 turist and that it has succeeded and Avill succeed is e\ndenced by the rapidly increas- 

 ing interest manifested in the manufacture, sale and use of spraying machines, and 

 the good results obtained by those who have practiced this mode of protection. 



Any of the Agriculttiral Experimental Stations will furnish bulletins so arr-anged 

 that the grower ma}- see at a glance what to apply, when and how to make the appli- 

 catiens. 



KORXIULAS. 



Bordeaux Mixture. — Copper sulphate, 6 pounds ; quicklime. 4 pounds ; water, 

 40 to 50 gallons. Dissolve the copper sulphate by putting it in a bag of coarse cloth 

 and hanging this in a vessel holding at least 4 gallons, so that it is just covered bv 

 the water. Use an earthen or wooden vessel. Slake the lime in an equal amount of 

 water. Then mix the two and add enough water to make forty gallons. It is then 

 ready for immediate use. If the mixture is to be used on peach foliag-e it is advis- 

 able to add an extra pound of lime to the above formula. When applied to such 

 plants as carnations or cabbages it will adhere better if about a pound of hard soap 

 be dissolved in hot water and added to the mixture. — For rots, moulds, mildews and 

 all fungous diseases. 



Copper Sulphate Solution. — Copper sulphate, i pound ; water, 15 gallons. Dis- 

 solve the copper sulphate in the water, when it is readv for use. This should never 

 be applied to foliage, but must be used before the buds break. For peaches and 

 nectarines use 25 gallons of water. — For fungous diseases. 



Paris Green. — Paris green, i pound; Avater, 200 gallons. If this mixture is to 

 be used upon peach trees, i pound of quicklime should be added. Repeated appli- 

 cations will injure most foliage, unless lime is added. Paris green and Bordeaux 

 mixture can be applied together with perfect safety. Use at the rate of 4 

 ounces of the arsenites to 50 gallons of the mixture. The action of neither is weak- 

 ened, and the Paris green loses all caustic properties. — For insects which chew.' 



London Purple. — This is used in the same proportion as Paris green, but as it 

 is more caustic it should be applied with two or three times its weight of lime, or 

 with the Bordeaux mixture. The composition of London purple is exceedingly 

 variable, and unless good reasons exist for supposing that it contains as much arsenic 

 as Paris green, use the latter poison. Do not use London purple on peach or plum 

 trees unless considerable lime is addqd. — For insects which chew. 



Hellebore. —Fresh white hellebore, i ounce : water. 3 gallons. Apply Avhen 

 thoroughly mixed. This poison is not so energetic as the arsenites, and may be used 

 a short time before the sprayed portions mature. — For insects which chew. 



Kerosene Emulsion. — Hard soap, ^s pound: boiling water, i gallon; kerosene, 

 2 gallons. Dissolve the soap in the water, add the kerosene, and chum with a pump 

 for 5-10 minutes. Dilute 10 to 25 times before applying. Use strong emulsion for 

 all scale in.'^ects. — For insects which S-uck^ as plant lice, mealy bugs, red spiders, 

 thrips, bark lice or scale. Cabbage worms, currant worms and all insects which 

 have softiodies can also be successfullv treated.
