Whale Oil or Fish Oil Soap: 



Has been used extensively for aphids, etc. For green aphids, like the 

 Cabbage Aphis, it should be used in the strength of one pound to 6 gallons 

 of warm water; for brown aphids or thrips, in the strength of one pound to 

 4 gallons of water. 



Tobacco Extracts: 



Trade preparations of nicotine are sold by nearly all seedsmen. Two of 

 these which are widely used for sucking insects are "Nickoteen" and "Black 

 Leaf 40." It is desirable to add soap to the diluted spray at the rate of 

 about two pounds to 40 gallons of mixture.
