Description
Sincocin is the trade name of the mixture registered
in 1997 as “Plant Extract 620” with the U.S. EPA.
It consists of a blend of extracts from the prickly
pear Opuntia lindheimeri, the oak Quercus falcata, the
sumac Rhus aromatica, and the mangrove Rhizophora
mangle. Sincocin has provided control of the citrus
nematode on orange roots (34), the reniform nematode
on sunflower (35), and the sugarbeet cyst nematode (36);
but control of M. incognita on cassava and R. similis on
anthurium was less successful than that provided by other
methods (37,38). Its mode of action has not been fully
elucidated.
Pharmacology
In general, nematode developmental stages that are
active are more susceptible to nematicides than are resting
stages (12,39). The detailed 20-year-old review by
Wright (40) on nematicidal mode of action remains relevant
because few new nematicides have been introduced
since its publication. Moreover, the broad-spectrum activity
of most nematicides has resulted in much of their
basic biochemical effects being documented in insects or
mammals instead of nematodes.
