The coccids ( Pseudococcu s citri Risso and P. adonidum L.) on 
greenhouse plants were controlled "by spraying with nicotine oleate. 
Beetles ( Epicauta pennsylvanica D eG.), which attacked aster flowers,,

This spray has had an extensive use among commercial growers for 
controlling aphids, capsid bugs, apple and pear suckers, young scale 
insects, red spiders on cucumbers and tomatoes, and woolly aphids on 
various plants. 
This emulsion is in reality a colloidal solution, and the particle 
can be seen only with the aid of an ultra microscope. In the nicotine 
petroleum emulsion we have a compound which embraces the various classes 
of insecticides, and on this account, and in view of its colloidal state, 
it should find extensive use among commercial growers generally.
