Stock solution, 1 gallon. 

 Water, 16 gallons. 

 Milk of lime whitewash, 3 gallons. 

 Paris green, 4 ounces. 



The object of this preparation is to obtain an adhesive 

 material which will cause the poison to stick to smooth 

 leaves. It may also be used with bordeaux mixture in the 

 proportion of 2 parts of the stock solution to 48 parts of 

 the bordeaux mixture. 



Kerosene Emulsion 



Hard soap, l / 2 pound. 

 Hot water (soft), 1 gallon. 

 Kerosene, 2 gallons. 



Cut the soap into small pieces and dissolve it in the 

 hot water. Add the kerosene immediately and churn it 

 violently at the same time. Pumping the mixture back 

 into itself for five or ten minutes with a hand force pump 

 or syringe is an excellent method of mixing, as the ma- 

 terials must be mixed until they form a thick creamy com- 

 bination in which no free oil shows on the surface. 



This is a concentrated mixture and must be diluted 

 before using. For use on apple and pear foliage, one gallon 

 of the emulsion should be diluted with nine gallons of 

 water. For cherry, peach or plum foliage, dilute with 

 twelve gallons, and for house plants dilute with fifteen 

 gallons. 



Tobacco 



Tobacco is used extensively in several forms for the 

 control of insect troubles. It can be obtained in the 

 market in several forms, either as a liquid, powder or 

 stems, to be used according to conditions. The fine powder 

 is used extensively about greenhouses and hotbeds for 

 green aphis, and in nurseries and orchards for woolly 

 aphis. It is scattered over the infested parts undiluted.
