COMPOSITION/INFORMATION ON INGREDIENTS Ingredients CAS No. Proportion Thifensulfuron methyl % Inert Ingredients Not allocated 50% 4. FIRST AID MEASURES Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek Medical attention. Skin Contact In case of contact, immediately wash skin with soap and water. Wash contaminated clothing before reuse. Eye Contact In all cases of contact, immediately flush eyes with plenty of water for at least 15 minutes. Seek Medical attention.

Not a fire and explosion hazard. However may be ignited by heat or open flame. Keep away from heat, sparks and flames. Like most organic powders or crystals, under severe dusting conditions, this material may form explosive mixtures in air. Water spray, dry chemical or CO2. Wear self-contained breathing apparatus. If area is heavily exposed to fire and if conditions permit, let fire burn itself out since water may increase the contaminated area. 2Z 6. ACCIDENTAL RELEASE MEASURES Spill precautions Spill containment Spill clean-up Use appropriate Personal Protective Equipment during clean up. (See Section 8) Dyke spill. Prevent liquid from entering the sewers, waterways, or low areas. Shovel or sweep up. DO NOT flush with water. Place material in a clean, dry container and cover for disposal. Wash contaminated areas with water and detergent. Prevent liquid from entering sewers, waterways or low areas. Soak up with sawdust, sand or other absorbent material. Shovel or sweep up. Never return to container for reuse. (See section 13 for disposal instructions.) 7. HANDLING AND STORAGE Handling Storage Avoid skin and eye contact. Avoid inhaling the vapour, or spray mist. Wash thoroughly after handling. Wash clothing after use. Store in the closed, original container in a dry, well ventilated area, as cool as possible out of direct sunlight and under lock and key. Keep from contact with fertilisers, fungicides and seeds. Do not store with Classes 1, 2, 3.2, 4 or 5 substances. Stores containing more than 100 kg of this product, either alone or in aggregate with other hazardous substances are subject to requirement of an emergency management response plan, secondary containment and signage. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Engineering Controls Exposure Standards Personal Protection Use only with adequate ventilation. AEL (DuPont): 1 mg/m 3, 8 hr TWA May irritate skin. Avoid contact with eyes, skin or clothing. Avoid breathing dust, vapours or spray mist. Wear gloves and overalls when mixing or spraying. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. DuPont (New Zealand) Limited Page 2 of 5

STABILITY AND REACTIVITY Stability Incompatibility Decomposition Polymerisation Stable at normal temperatures and storage conditions. No incompatibilities reasonably foreseeable. Decomposition will not occur Polymerisation will not occur. 11. TOXICOLIGICAL INFORMATION Acute Effects Eye Skin Inhalation Swallowed Chronic Effects Thifensulfuron methyl Not an eye irritant Not a primary shin irritant or sensitiser. Low toxicity. Low level of toxicity. None established for formulated product. No oncogenic effects observed in the 18 month mouse, 2 year rat, or 1 year dog feeding studies. Lower body weights and weight gains were observed for rats fed the highest dietary concentrations, 2,500 ppm. The no-observable-effect levels (NOEL) were 500 ppm and 25 ppm for the body weight and serum sodium effects, respectively. There were no compound-related effects in mice fed for 18 months with diets that contained the active ingredient. The NOEL was 7,500 ppm, the highest dose tested. Slightly lower body weights and higher liver weights were observed for dogs fed for 1 year with diets that contained 7,500 ppm. There were no microscopic or functional changes associated with these effects. The NOEL was 750 ppm. No effect on rat reproduction or lactation at any dose tested (highest dose tested 2,500 mg/kg.) There were no gross or microscopic compound-related effects on the offspring at any dose tested. Not mutagenic in the Ames bacterial assay; the in vitro Chinese Hamster Ovary Assay; the in vitro unscheduled DNA synthesis; the in vivo cytogenetic assay or in the mouse micronucleus assay. No teratogenic effects in rats at 800 mg/kg/day (highest dose tested), nor in rabbits at 650 mg/kg/day (highest dose tested). DuPont (New Zealand) Limited Page 3 of 5
