Specification
GardenTech Daconil Fungicide Concentrate
Germ Cell Mutagenicity: Neither chlorothalonil nor its metabolites interact with DNA and thus are
not mutagenic. Chlorothalonil was negative in the Ames assay and the micronucleus test in mice
bone marrow.
Reproductive Toxicity: None of the components are reproductive hazards. Chlorothalonil did not
cause teratogenic effects in rabbit or rats in oral studies.
Carcinogenicity: Chlorothalonil is classified by IARC as Possibly Carcinogenic to Humans (2B). No
evidence of carcinogenicity in dogs after administration for up to one year. Treatment related
increases in the incidence of renal tubular and carcinoma re observed in rats and male mice.
Squamous cell adenomas and carcinomas were also observed in the forestomach of both species.
The forestomach tumors seen in rodent studies re not relevant to human health, as humans do not
possess an anatomical equivalent of the rodent forestomach. The relevance of renal tumors to
human health is unclear, although metabolism data suggest that the dog, a species that is resistant to
chlorothalonil-induced renal injury, may be more representative of humans than the rat. Tumor
formation has been related to a non-genotoxic mechanism of action for which threshold levels have
been established in rats and mice. Comprehensive dietary and worker exposure studies have shown
exposure levels for humans to be well below these threshold levels. In addition, surveillance of
chlorothalonil plant workers for over twenty years has not demonstrated any increase in oncogenic
potential to humans. None of the other components are listed as carcinogens or suspected
carcinogens by IARC, NTP, ACGIH or OSHA.

12. ECOLOGICAL INFORMATION
Ecotoxicity values: Product is very toxic to the environment with long-lasting effects.
This product is toxic to aquatic invertebrates and wildlife. Do not apply directly to water, to areas
where surface water is present or to intertidal areas below the mean high-water mark. Drift and run-
off may be hazardous to aquatic organisms in neighboring areas. Do not contaminate water when
disposing of equipment wash water or rinsate.
Chlorothalonil: Bees LC/EC50: >181 ug/bee; Daphnia magna LC50/EC50: 0.068 ppm; Trout
LC/EC50: 0.04 ppm; Bluegill LC/EC50: 0.06 ppm; Birds – Bobwhite Quail LC50/EC50: >5200 ppm/8-

Persistence and degradability: Chlorothalonil is not persistent in soil or water.
Bioaccumulative potential: Chlorothalonil has a low to moderate bioaccumulation potential.
Mobility in soil: Chlorothalonil has low mobility in soil.
Other adverse effects: None known.
13. DISPOSAL CONSIDERATIONS
Dispose in accordance with all local, state and federal regulations. No specific disposal method is
recommended.
Pesticide disposal: Nonrefillable container; do not reuse or refill this container. If empty: Place in
trash or offer for recycling, if available. If partly filled: Call your local solid waste disposal agency for
disposal instructions. Never place unused product down any indoor or outdoor drain. Container
disposal: Triple rinse (or equivalent) container promptly after emptying. Tripe rinse as follows: Empty
the remaining contents into application equipment or a mix tank and drain for 10 seconds after the
flow begins to drip. Fill the container ¼ full with water and recap; shake for 10 seconds. Pour rinsate
