      ACGIH RECOMMENDED LIMIT:  None established
      TOXICOLOGY
           A.  ACUTE TOXICITY
               DERMAL:  Prolonged contact to skin could cause irritation.
                        Absorption through skin is minimal (58).
               ORAL:    LD50 = 0.65 - 2.42 g/kg (rat) (58).
               INHALATION:  No hazards expected from inhalation (58).
               EYES:    Prolonged contact to eyes could cause irritation (58).
           B.  SUBACUTE AND CHRONIC TOXICITY:
           Doses of 2 to 4 mg/kg of copper, the active ingredient, are
      harmless to rats.  Six to 9 mg/kg of copper may be harmful (58).
                         IV.  ENVIRONMENTAL CONSIDERATIONS
      Behavior In Or On Soils
      1.   Adsorption and leaching characteristics in basic soil types:
             Complex may be adsorbed to soil particles in high organic
             sediments.
      2.   Resultant average persistence at recommended rates:  May persist
             indefinitely due to elemental nature of copper (58).
      General to toxicity to wildlife and fish:  Generally nontoxic to
           fish and wildlife at recommended dosages.  Trout, tropical
           fish, ornamental goldfish, and certain other sensitive fishes
           may be adversely affected in very soft water (below 50 ppm of
           CuCO3) (58).
                       V.  EMERGENCY AND FIRST AID PROCEDURES
           The chemical information provided below has been condensed from
      original source documents, primarily from "Recognition and Management
      of Pesticide Poisonings", 3rd ed. by Donald P.  Morgan, which have been
      footnoted.  This information has been provided in this form for your
      convenience and general guidance only.  In specific cases, further
      consultation and reference may be required and is recommended.  This
      information is not intended as a substitute for a more exhaustive
      review of the literature nor for the judgement of a physician or other
      trained professional.
           If poisoning is suspected, do not wait for symptoms to develop.
      Contact a physician, the nearest hospital, or the nearest Poison
      Control Center.
      SYMPTOMS OF POISONING:  Loss of appetite, jaundice, and
               accumulation of copper in the liver (58).
           SKIN CONTACT:  Thoroughly wash contaminated skin (58).
           INGESTION:  If swallowed, call a doctor (58).
           EYE CONTACT:  Thoroughly wash contaminated eyes (58).
                        VI.  FIRE AND EXPLOSION INFORMATION
           Nonflammable (58).
                                VII.  COMPATIBILITY
           Virtually noncorrosive (58).
           Conditions to avoid:  Contamination with acids, exposure of
      granular formulation to temperatures above 150 F, especially if
      material is damp (56).
                             VIII.  PROTECTIVE MEASURES
      STORAGE AND HANDLING:  Indefinite shelf life, stable to light.  Stable
      to temperatures below freezing and above 90 C (58).
           Keep out of reach of children.  May cause skin damage.  Do not get
      on skin, eyes, or clothing (56).
      PROTECTIVE CLOTHING:  Wear rubber gloves and protective eyewear when
      handling concentrate (56).
                        IX.  PROCEDURES FOR SPILLS AND LEAKS
