Controlling Brown Rot 



{Continued from page 4) 

 started add 32 lbs. of ordinary sulphur, 

 previously screened to take out foreign 

 matter and break up the lumps. Stir 

 vigorously to keep the material from 

 "burning" and adhering to the bottom 

 of the barrel, adding water as necessary 

 until the lime is all slaked. For peaches 

 it is well to stop the action at the end of 

 15 or 20 minutes by filling the barrel 

 with cold water, but the spray can be 

 improved for hardier fruits by tightly 

 covering the barrel and holding its con- 

 tents hot for a longer period. Enough 

 water should he added in any case to 

 make it easy to screen into the spray 

 tank for the removal of small particles 

 that would otherwise clog nozzles and 

 cause trouble in the valves. 



THE addition of a spreader or 

 "sticker" is essential to best results 

 with any spray material, more especially 

 on smooth fruit surfaces, such as cher- 

 ries and plums have. In the absence of 

 a spreader the spray gathers in drops 

 and "runs off like water from a duck's 

 back." With Bordeaux and self-boiled 

 lime-sulphur various soaps may be used. 

 A good spreader of this type is the resin 

 fish-oil soap which may be made at home 

 by the following formula: 



Lye, such as used for washing 1 lb. 



Resin 5 lhs. 



Fish Oil 1 pint 



Water 5 gallons 



Dissolve the resin by heating in the 

 oil in a large kettle. After this has par- 

 tially cooled, add the potash; stir slowly 

 and watch to prevent its boiling over. 

 Then add a part of the water and con- 

 tinue boiling until the mixture will dis- 

 solve in cold water. Then add the re- 

 mainder of the water. Use about one 

 quart of the soap to 50 gallons of spray. 



Soaps are not suitable for use with 

 commercial lime-sulphur and even with 

 Bordeaux and self-boiled lime-sulhpur 

 they are frequently objected to on ac- 

 count of the excessive foaming in the 

 tank. Casein is not open to this objec- 

 tion and forms a very efficient spreader 

 with any spray material. It is best pre- 

 pared in a stock solution, as follows: 



Take one pound of the ordinary com- 

 mercial granulated or powdered casein 

 that can be obtained through druggists 

 or wholesalers and slowly stir it into a 

 gallon of water in which has been dis- 

 solved three ounces of caustic soda or 

 ordinary "potash lye," and bring the 

 mixture to a boil. The same care must 

 be used in adding the casein as would 

 apply if flour were used, since sticky 

 lumps that are hard to dissolve may 

 otherwise form. For use take one quart 

 of the resulting solution to 200 gallons 

 of spray.

Grasselli-Grade Insecticides cut them off in the "flower of 

 their youth" — before their voracious appetites have ruined your 

 fruit crop and income. Certain — positive — unfailing in results — 

 when you spray with Grasselli Grade you are SURE of protec- 

 tion — you have put a padlock on your season's fruit income (so 

 far as the insects and fungi are concerned). 



Grasselli Grade Insecticides and Fungicides are absolutely un- 

 varying in strength and quality — they must be so in order to 

 earn the Grasselli label, to align with the world-wide Grasselli 

 name and 82 years of chemical leadership. 



Specify GRASSELLI GRADE when you order your spray 

 nd INSURE your fruit crop. ThereV
