Where It Comes From
Former farm pesticide used on field crops; not for residential use; can move with runoff and briefly persist in soil [1].
How You Are Exposed
Mainly at work when mixing or applying, from drift, or by touching contaminated plants/equipment; swallowing or breathing small amounts can be dangerous [1][3].
Why It Matters
Can cause headache, nausea, sweating, pinpoint pupils, weakness, breathing trouble, seizures; high doses can be fatal without rapid care [3][2].
Who Is at Risk
Farmworkers and pesticide applicators, people living near treated fields, and children (more hand-to-mouth contact) [1].
How to Lower Your Exposure
Don’t use old disulfoton products; follow re-entry intervals and drift setbacks; wear proper PPE; wash hands, clothing, and tools after work; wash produce; keep kids away from fields; seek medical help if exposure is suspected [1][3].
