THE ONION 



Enemies. The most troublesome disease of 

 the onion is the Downy Mildew. It appears in 

 mid-season when the weather is warm and 

 °iuggy. If a downy velvet covering appears 

 on the fohage, spray with Bordeaux Mixture, 

 which will check and prevent the spread of the 

 disease. If the tops drop and the bed is badly 

 infected, burn the tops and plant other crops 

 on the soil used for onions. 



The worst insect in the North is the Onion 

 Maggot. The maggot works on the roots and 

 while one cupful of kerosene to a pail of sand 

 sprinkled in a furrow made close to the grow- 

 ing plants may partly check the maggot, it is 

 best to stir the soil late in the fall, leave it in 

 the rough exposed to the weather, and plant 

 other crops on the soil for three or four years. 



In the South, Thrips are quite common. 

 Spraying with kerosene emulsion or a stand- 

 ard solution of Bordeaux Mixture will repel 

 them. This insect usually appears on a sickly 

 crop.
