CHAPTER XII 



INSECTICIDES AND FUNGICIDES 



THERE are a number of proprietary articles on the market 

 which are valuable for killing insect pests. When these 

 are used the directions should be followed carefully, and, if in 

 doubt as to the results, as with a new article, try it on a small 

 scale at first. Where tobacco stems can be obtained cheaply 

 they may be steeped in warm water and the liquid used when 

 fresh as a spray. Use it full strength after first making a test 

 on a small scale. Stems of tobacco may be burned when no 

 flowers are being cut, but this is not recommended; it is dirty 

 in its operation, makes a lot of work, and often does harm to the 

 flowers. Tobacco dust may be used by burning, or by being 

 dusted on the plants; it is a remedy for thrips, green fly, etc. 



KEROSENE EMUCSION 



Is made by first shaving fine one pound of hard soap. Dissolve 

 this in two gallons of boiling water, stir well, and while hot 

 add four gallons of kerosene. Churn this well with a spray pump 

 until an emulsion is secured ; when this takes place it will be 

 readily noticed. Dilute this stock mixture, when used, as the 

 conditions require, adding at least ten parts of water to one 

 part of the emulsion. This is a good spray for red spider, 

 thrips, etc., and imparts a leathery texture to the foliage which 

 some growers claim is mildew resisting. 



HELLEBORE 



May be dusted on the flower buds and foliage for thrips and 

 kindred troubles. Apply this on the under side of the foliage 

 when damp so it will adhere.
