Abstract:
DDVP, with the common name dichlorvos, has an
active ingredient, 2,2-dicWorovinyl dimethyl phosphate,
which was flrst introduced by Ciba Geigy AG
under the trademark "Nuvan" and by Shell Chemical
Co. under the trademark ''Vapona''.
In Korea, DDVP has been tested for five years but
continuous evaluation has also been carried out in
many countries of the world.
DDVP has contact, stomach and breathing poison
actions. It provides sure control of sucking, biting and
mining pests such as aphids, spider mites, caterpillas
and beetle larvae. On account of its very fast killing
action and the relatively rapid rate at which it is
broken down on the plant, it can be used safely on
crops close to harvest.
DDVP features good plant tolerance, but it is harmful
to bees.
