Pymetrozine CAS 123312-89-0

1. Pymetrozine is a selective insecticide used to control aphids, whiteflies, and plant hoppers in a wide range of crops including vegetables, fruits, cotton, and rice .
2. Pymetrozine functions by interfering with the feeding behavior of piercing-sucking insects, causing them to stop feeding shortly after exposure, ultimately leading to starvation .
3. Pymetrozine is utilized in integrated pest management (IPM) programs due to its low toxicity to beneficial insects such as bees, ladybirds, and predatory mites .
4. In environmental and agricultural research, pymetrozine serves as a reference standard for monitoring pesticide residues in food and environmental samples .

1. Pymetrozine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, away from direct sunlight and sources of ignition .
2. Pymetrozine is classified with GHS hazard statements H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling pymetrozine, ensuring adequate ventilation in work areas .
4. Keep Pymetrozine away from incompatible materials such as strong oxidizing agents to prevent decomposition; avoid release to the environment and prevent the product from entering drains or water courses .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Pymetrozine is released .
2. Collect Pymetrozine CAS 123312-89-0 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent pymetrozine from entering drains or water courses .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Pymetrozine is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Pymetrozine may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Pymetrozine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
