INSECT PESTS AND DISEASES 



LIKE all other classes of plants, Chrysanthemums get 

 their full share of attack from insects. The most 

 prevalent is perhaps the green-fly. 



These creatures will find their way to quite small 

 plants in the early season, and their descendants will be 

 found attending the plant in its old age unless a continual 

 warfare is waged against them. 



When the fly attacks the plant in a young stage, the 

 safest plan is to fumigate the house or frame that contains 

 the plants. Choose a damp, quiet night for the operation. 

 Wind will soon blow out the vapour, which will mean 

 fumigating over again ; as the fumigant will not have had 

 sufficient time to act upon the fly. Should it be found 

 next morning that all the fly is not dead, another slight 

 fumigating may be given. This should be done before the 

 day gets far advanced on account of having to keep the 

 premises closed. If impossible to fumigate, owing to 

 high winds or other causes, the next best system is to 

 dust tobacco powder over all the parts affected. This 

 should be syringed off the following day. If allowed to 

 stay on for too long a period I have found some tobacco 

 powders to have a tendency to mark the foliage. 



When the plants have grown and have been placed 

 permanently in their summer quarters, fumigating will 

 be out of the question. The only remedies then will be 

 to dust with tobacco powder, as previously suggested, all 

 points under foliage and any place where the fly is likely 

 to harbour. 



Another very good and efficient remedy consists in
