Piperonyl butoxide (PBO) is a pale yellow to light brown liquid [1] organic compound used as an adjuvant component of pesticide formulations for synergy.That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.

Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
ATSDR has a computational toxicology laboratory that conducts research and modeling on the effects of toxic substances on human health. The agency's toxicology work involves pharmacokinetic / pharmacodynamic modeling, quantitative structure–activity relationship methods, and benchmark dose modeling, as well as establishing minimal risk levels ...
Pyrethrum rapidly knocks down flying insects but has negligible persistence — which is good for the environment but gives poor efficacy when applied in the field. Pyrethroids are essentially chemically stabilized forms of natural pyrethrum and belong to IRAC MoA group 3 (they interfere with sodium transport in insect nerve cells). [29]
The Times and WeedWeek testing also found another off-list chemical, propargite, a carcinogenic insecticide that UCLA researchers have linked to brain-cell death and increased incidence of ...
Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization. It addresses the acute toxicity of agents such as soil fumigants , fungicides , herbicides , insecticides , miticides , molluscicides , nematicides , or rodenticides .
Studies have shown that it can reduce the amount absorbed if given within 60 minutes, [37] though there is not enough data to determine if it is effective if time from ingestion is prolonged. Syrup of ipecac is not recommended for most pesticide poisonings because of potential interference with other antidotes and regurgitation increasing ...
