suggested to utilizing Lantana for purifying highly polluted water
by treating it with its filtrate or leachate to eliminate algal bloom
or pathogenic microorganisms and aquatic free-floating weeds.
Saxena (1991) has reported that Lantana is toxic for free floating
macrophytes. There are several reports from India where people
are using the dried leaves of Lantana to suppress weeds in the tea
garden and in ponds to reduce larval growth. Orange flowers
(Townsville prickly orange) variety had minor quantity of
lantadene A and lantadene B but contained Oleanolic acid and
Ursolic acids as major component (Sharma and Sharma, 1989).
This plant also contains salicylic acid (Jain et al., 1989), a
phenolic compound which is regarded as a strong allelochemical
to retard the growth of neighboring plants. Lantana has potential
for effective control of water hyacinth which needs to be
investigated for management of highly polluted water. There
should have been various trials for integrated management of
water hyacinth using a combination of aqueous leachate of
Lantana along with other biological agents
