Precautionary Statements: Wear protective gloves and clothing, avoid breathing spray, do not discharge into drains or surface water, avoid contact with skin and eyes
Active Ingredient: Pyraclostrobin (chemical purity commonly above 98%)
Other Ingredients: Solvents, emulsifiers, surfactants, inert carrier substances supporting formulation stability
Concentration: Pyraclostrobin typically ranges from 20%-50% depending on formulation type (SC, WG, EC, etc.)
Threshold Limit: Refer to manufacturer or regional regulatory guidelines for safe exposure and handling limits of all constituents
Inhalation: Move affected person to fresh air. Keep warm and at rest. Seek medical help if symptoms develop.
Skin Contact: Remove contaminated clothing. Wash affected skin thoroughly with soap and water. Get medical attention if irritation persists.
Eye Contact: Rinse immediately with plenty of clean water for at least 15 minutes, keeping eyelids open. Remove contact lenses if possible. Seek medical advice.
Ingestion: Rinse mouth with water, do not induce vomiting, and seek immediate medical attention.
Medical Advice: Inform healthcare personnel of product identity. Treat symptomatically. There is no specific antidote.
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Media: High-pressure water jets may spread contamination
Specific Hazards: Burning may release hazardous gases such as carbon monoxide, nitrogen oxides, hydrogen chloride
Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Special Procedures: Prevent runoff from entering waterways or drains; contain spillage with absorbent barriers as possible.
Personal Precautions: Use chemical-resistant gloves, safety goggles, long-sleeved clothing, and a particulate respirator if significant dust or vapor present
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid release into soil, sewers, drains, and surface water
Spill Clean-Up: Absorb spillage with inert material (sand, earth, or absorbent pads), collect and place in suitable container for disposal. Wash spill area thoroughly with water, collecting washings to avoid discharge
Safe Handling Practices: Avoid contact with skin and eyes, do not inhale dust, vapor, or spray. Maintain good industrial hygiene; keep product in original, tightly closed containers.
Storage Conditions: Store in a cool, dry, well-ventilated area, away from direct sunlight, sources of ignition, and incompatible materials (strong oxidizers, acids).
Incompatibilities: Prevent exposure to heat and reactive agents. Store away from food and animal feed.
Engineering Controls: Work in well-ventilated areas, use local exhaust ventilation in enclosed spaces
Personal Protective Equipment: Gloves (chemical-resistant, such as nitrile), overalls or protective clothing, safety goggles, respiratory protection if spray mist or dust forms
Hygiene Measures: Wash hands and exposed skin before eating, drinking, or smoking. Wash work clothing separately.
Appearance: Off-white to beige crystalline solid (pure active); formulated products may appear as granules or liquid suspensions
Odor: Mild aromatic or solvent-like, depending on formulation
pH: Approximately neutral in water (6-8)
Melting Point: 63-66°C
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: >100°C (formulation dependent)
Solubility: Low solubility in water, higher in organic solvents
Vapor Pressure: Extremely low at 20°C
Density: 1.25–1.30 g/cm³
Partition Coefficient (log Kow): 3.9–4.1
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Not reactive under normal circumstances; avoid acids, bases, and strong oxidizing agents
Decomposition Products: Can produce hazardous gases such as oxides of carbon, nitrogen, and hydrogen chloride if heated to decomposition
Polymerization: Will not occur under standard conditions
Acute Toxicity: Oral LD50 (rat) ~2,600 mg/kg; Dermal LD50 (rat) >2,000 mg/kg; Inhalation LC50 (rat, 4h) >1.8 mg/L
Skin Irritation: Mild to moderate irritant potential
Eye Effects: May cause eye irritation
Chronic Exposure: No clear evidence of carcinogenic or mutagenic potential at low exposure levels; long-term or repeated exposure to high doses can impact liver or blood in lab animals
Sensitization: Possible skin sensitizer
Other Potential Effects: Not known to target reproductive organs at agricultural exposure levels
Aquatic Toxicity: Highly toxic to fish and aquatic invertebrates (e.g., LC50 for rainbow trout around 4.0 µg/L)
Persistence: Moderately persistent in soil; potential for bioaccumulation (log Kow >3)
Degradation: Degrades by microbial activity; breakdown products may be less toxic in water, but risk of sediment buildup persists
Mobility: Binds to soil particles, low risk of leaching under normal field conditions
Non-target Organisms: Minimal impact on birds, moderate risk to bees by direct contact with freshly treated surfaces
Precaution: Not suitable for use near water bodies, restrict spray drift, and comply with setback distances listed on the product label
Product Waste: Collect unused product and waste in sealed containers. Handle as hazardous chemical waste for incineration under controlled conditions.
Contaminated Packaging: Rinse empty packaging thoroughly and dispose under local regulations through an approved waste contractor. Avoid reuse of packaging for any purpose.
Other Disposal Notes: Do not allow product or rinse water to enter sewers, drains, or watercourses. Dispose of in accordance with local authorities and national/international regulations.
