Avoiding Plant Ills 



Plant ills, like insects, are much less a menace 

 than formerlj^ Sunlight, clean surfaces, and 

 concrete are discouraging to obnoxious germs and 

 spores. Occasionally, however, some of the fol- 

 lowing diseases may appear: 



Mildew. — This is usually induced by a sudden 

 change or drop in temperature. The common 

 method of control is to dust the plants with flour 

 of sulphur, or to evaporate sulphur on the heat- 

 ing pipes. (Make a thin paste of sulphur and 

 water and paint it on the hot pipes; or use a 

 regular fumigator.) Roses and a few other 

 plants are particularly subject to attacks of 

 mildew, which causes the leaves to be covered 

 with a. powdery white substance, and in some 

 cases to curl up, or even drop ojff. 



Blight, — In growing a miscellaneous assort- 

 ment of plants, especiall}^ if some are brought 

 in from outside, there may be an occasional 

 attack of some form of blight. Some of these 

 cannot be cured but they usually can be con- 

 trolled, so that they will not spread to other 

 plants. In such cases bordeaux mixture is the 

 standard thing to use. Dead plants and leaves 

 should be promptly gathered up and burned.
