The onion fly lays her eggs on the leaves of the 

 young and small onion plants, near the ground 

 They soon hatch, and the maggots at once attack 

 the bulb. In about two weeks after this a second 

 brood of flies appears, to be followed by more 

 maggots. The remedy at this stage consists in 

 removing every infested bulb. These may be 

 known by the leaves turning yellow. They can- 

 not be pulled up by the tops without risk of letting 

 the maggot escape from the decayed bulb. They 

 must be lifted by a trowel, or an old knife, so as to 

 be sure to bring up the maggot. The bulbs so 

 removed, and the maggots, must be burned. 

 Strong caustic lime-water, and concentrated solu- 

 tions of kainite or muriate of potash are said to be 

 safe and sure remedies when applied in time. A 

 pint or half-pint of the liquid is to be poured upon 

 every plant, making sure of reaching the infected 

 root. This will kill the eggs in the ground as well 

 as the maggot in the root by simple contact. 

 Plants once seriously affected can hardly ever be 

 saved.
