Used in: Crop protection, specifically for managing spider mites and whiteflies on vegetables, fruits, and ornamental plants
Hazard Classification: Often classified as hazardous to aquatic environments; moderate risk for human contact
Main Risks: Eye irritation, skin irritation, mild toxicity if ingested, potential respiratory discomfort upon inhalation of dust
Environmental Impact: Expected to be very toxic to aquatic organisms, persistent in water and soil
Signal Word: Warning according to most global regulatory systems
Active Ingredient: Spiromesifen, typically between 20% to 23% for formulated products
Other Ingredients: Fillers, surfactants, binders, often undisclosed as proprietary
Chemical Formula: C23H30O4
CAS Number: 283594-90-1
Inhalation: Move person to fresh air; possible mild respiratory irritation
Skin Contact: Wash affected area with plenty of water and mild soap; remove contaminated clothing
Eye Contact: Rinse with clean water for several minutes, seek medical attention if irritation continues
Ingestion: Rinse mouth; seek medical advice, do not induce vomiting unless directed by a professional
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray for larger fires
Hazardous Combustion Products: Fumes containing carbon monoxide, carbon dioxide, unknown toxic gases
Fire-Fighting Instructions: Firefighters should wear full protective gear and self-contained breathing apparatus; avoid runoff from fire control
Personal Precautions: Prevent skin and eye contact; use personal protective equipment
Containment: Prevent from entering waterways or sewers; sweep or scoop up spilt material and place in secure container
Decontamination: Wash spill area thoroughly after cleanup, ventilate area
Handling: Use only with adequate ventilation; avoid dust formation and direct contact with skin or eyes
Storage: Store in cool, dry, well-ventilated space; keep container tightly closed and away from food or animal feed
Precautions: Prevent unauthorized access; keep away from sources of heat and ignition
Exposure Limits: No established occupational exposure limits for spiromesifen as a technical compound
Engineering Controls: Local exhaust or general ventilation preferred in handling areas
Personal Protective Equipment: Chemical-resistant gloves, protective eyewear, long-sleeve clothing, dust mask or respirator if dust is generated
Hygiene Measures: Wash thoroughly after handling and before eating, drinking, or smoking
Physical State: Typically a solid powder
Color: Off-white to light beige
Odor: Faint, not easily identified
Solubility: Very low in water, higher in organic solvents
Melting Point: Approximately 208°C
Density: About 1.2 g/cm³ (pure substance)
Chemical Stability: Stable under recommended storage conditions
Reactivity: May react with strong acids or bases; incompatible with strong oxidizing agents
Conditions to Avoid: Direct sunlight, high temperatures, open flame
Decomposition: Produces carbon oxides and potentially hazardous organic fumes if burned
Acute Toxicity: Generally low oral and dermal toxicity in humans
Inhalation: Short-term exposure may cause mild irritation
Skin/Eye Contact: Mild irritant to skin and eyes; not a skin sensitizer
Chronic Exposure: No clear evidence of carcinogenicity or reproductive toxicity in available studies; higher concern for aquatic effects, lower for chronic human health
Aquatic Toxicity: Extremely toxic to aquatic invertebrates and fish; can persist in sediment and water
Birds/Mammals: Lower toxicity expected for birds and mammals
Persistence: Tends to persist in soil and water; limited breakdown under natural sunlight
Bioaccumulation: Limited potential for bioaccumulation in higher organisms
Product Disposal: Dispose in compliance with local environmental regulations; avoid contaminating waterways
Container Disposal: Triple rinse containers, puncture, and dispose at approved waste sites; avoid reuse
Methods: Incineration preferred for significant quantities; small spills absorb on vermiculite and landfilled in accordance with regulations
UN Number: Often not assigned for standard formulations, but classified as hazardous when in bulk
Proper Shipping Name: Pesticide, solid, toxic, organic, n.o.s. depending on packaging and region
Hazard Class: May be considered environmentally hazardous during transport
Packing Group: Typically III (Minor risk during routine transport)
Global Status: Registered as an active substance in many countries for agriproducts; subject to pesticide use regulations
Labeling: Packaging normally requires clear hazard statements, precautionary pictograms, and user safety instructions
Worker Protection: Safety measures mandated by local authorities for mixing, application, and field entry after application
Restrictions: Many countries set pre-harvest intervals and usage rates to manage residues and food safety
