Directions for its use accompanies each of 

 them. Dusting the points of the plants, 

 while wet, with tobacco dust is an effective 

 remedy. This also should be applied at 

 night or during cloudy days, and should be 

 washed off with the hose and spray after a 

 few hours. Various liquid insecticides may 

 be used by spraying the plants with them. 

 Special efforts should be made to eradicate 

 this insect entirely at the time that the 

 buds are forming, as if any of them are 

 on the plants then they will work un- 

 der the scales of the buds and eventually 

 into the blooms, which will surely be 

 ruined. 



Red spider is an enemy for the existence 

 of which on chrysanthemum plants there 

 can be no excuse, provided a supply of water 

 is available and the means to apply it to the 

 under side of the leaves with reasonable 

 force. This is the best remedy of all for 

 this insect, and, as the chrysanthemum 

 makes its growth at a season of the year 

 when water can be used freely, should prove 

 an effective remedy. As with the aphis, 

 pains should be taken to have the plants 

 absolutely free from spider before the buds
