DIAZINON is the most widely used pesticide by homeowners on lawns, and is
one of the most widely used pesticide ingredients for application around
the home and in gardens. It is used to control insects and grubs. The
agreement betwen EPA and diazinon manufacturers (5 December 2000), Syngenta
and Makhteshim Agan, will eliminate 75 percent of the use which amounts to
more than 1 million pounds of the pesticide used annually. Diazinon's use
on turf poses a risk to birds, and it is one of the most commonly found
pesticides in air, rain, and drinking and surface water.
EPA is taking this action under the Food Quality Protection Act. EPA has
targeted a large group of older pesticides called organophosphates for
review because it feels they pose the greatest potential risk to children.
In August of 1999, for example, EPA announced action against methyl
parathion and azinphos methyl to protect children from pesticide residues
in food. Agency reached an agreement to halt by December 2000 the
manufacture of chlorpyrifos, or Dursban, for nearly all residential uses.
Diazinon, used in homes, and on lawns and gardens, is the latest
organophosphate to be phased out. Specifically, the terms of the agreement
implement the following phase-out schedules:
- For the indoor household use, the registration will be canceled on March 2001, and all retail sales will stop by December 2002.
- For all lawn, garden and
turf uses, manufacturing stops in June 2003; all sales and distribution
to retailers ends in August 2003. Further, the company will implement a
product recovery program in 2004 to complete the phase out of the
- Additionally, as part of
the phase out, for all lawn, garden, and turf uses, the agreement
ratchets down the manufacturing amounts. Specifically, for 2002, there
will be a 25 percent decrease in production; and for 2003, there will
be a 50 percent decrease in production.
- Also, the agreement begins the process to cancel around 20 different uses on food crops.
It is legal to purchase and
use diazinon products according to label directions and precautions.
