Aquatic life is extremely susceptible to pyrethrin toxicity, and has been documented in species such as the lake trout. Although pyrethrins are quickly metabolized by birds and most mammals, fish and aquatic invertebrates lack the ability to metabolize these compounds, leading to a toxic accumulation of byproducts.

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).
Pyrethrin I is one of the two pyrethrins, natural organic compounds with potent insecticidal activity. It is an ester of (+)-trans-chrysanthemic acid with ...
Pyrethrins and the similar pyrethroid compounds are known to have insecticidal properties, including against fungus gnats. [17] Related pyrethroid insectides have also been used. Pyrethrin compounds are known to occur in certain chrysanthemum flowers.
In a recent study by Kyoto University in Japan, researchers found that primates engage in socially contagious urination behaviors. Chimpanzees were observed to urinate around the same time ...
Many alkaloids, pyrethrins, and phenols are toxins. Tannins are major inhibitors of digestion and are polyphenolic compounds with large molecular weights. Lignin and cellulose are important structural elements in plants and are also usually highly indigestible.
Reese Witherspoon has a secret spirit animal. Witherspoon told BUILD Series her spirit animal is a squirrel and Matthew McConaughey, a penguin, when they visited to dish on their Illumination film ...
Cyhalothrin (ISO common name [3]) is an organic compound that, in specific isomeric forms, is used as a pesticide. [4] It is a pyrethroid, a class of synthetic insecticides that mimic the structure and properties of the naturally occurring insecticide pyrethrin which is present in the flowers of Chrysanthemum cinerariifolium.
