FIGURE 39.—Lilac (Melia azedarach L.) 
their introduction years ago, although they are now commonly planted 
as ornamentals. They thrive equally well in full sun or partial shade 
and on many different soil types. The plants, although the leaves fall 
in dry weather, require a moderate amount of moisture and are un- 
common in the drier windblown areas. 
Toxiciry AND Symproms.—No specific toxic substance from the 
lilac tree has been isolated and purified as yet (36, 67). Pigs are 
poisoned from eating either green or ripe berries. Goats, chickens, 
and ducks are less susceptible to lilac poisoning. Although the berries 
are the most toxic, flowers, leaves, and bark are also poisonous. Pigs 
show symptoms 3 to 4 hours after consuming berries. Chief sy mptoms 
are loss of appetite, stiffness, lack of coordination, and general weak- 
ness. Death frequently follows within 24 hours. One- half pound of 
berries is sufficient to kill a 50-pound pig (67). 
MANAGEMENT AND ContTrou.—Preventative measures should be 
stressed as a livestock management practice, especially with swine, 
because lilac trees occur in many accessible locations. Individual small 
plants found growing in undesirable locations should be grubbed out.
