PRACTICAL GARDENING 



broom so as to knock the beetles into the kero- 

 sene. 



Blight. The early blight appears when the 

 vines are young, causing them to turn yellow 

 and die. If Bordeaux mixture is applied by 

 spraying at the time and in combination with 

 the poison to control the potato beetle, the 

 blight will be prevented. 



The late blight appears from two to four 

 weeks after the first potato beetles appear and 

 especially during a rainy period. Spray sev- 

 eral times during the season with Bordeaux. 

 The disease attacks the leaf causing dark, 

 water-soaked areas which are covered with 

 white mildew in a few days after the disease 

 first puts in its appearance. The leaves close 

 to the soil where there is considerable moisture 

 are usually the first to show signs of the dis- 

 ease. The affected tissue soon decays and 

 spreads to adjoining plants and to the tuber, 

 causing irregular discolored areas on the 

 potato, which later become sunken and form a 

 dry rot.
