The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient. The AI is usually formulated with other materials (adjuvents and co-formulants) and this is the product as sold, but ...
Its active ingredient is alkyl dimethyl benzyl ammonium chloride (5.12% by volume); sodium nitrite and blue dye are also present. [2] Barbicide is sold as a concentrate diluted for use in a ratio of 2 ounces (57 g) of Barbicide concentrate mixed into 32 ounces (910 g) of water, [3] with each stylist having a container for treating their own tools.
The New York State Agricultural Experiment Station recipe for the concentrate suggests starting with 80 lb. of sulfur, 36 lb. of quicklime, and 50 gal. of water, equivalent to 19.172 kg of sulfur and 8.627 kg of calcium oxide per 100 litres of water.

Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses.
Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. [5]C 10 H 7 OH + CH 3 NCO → C 10 H 7 OC(O)NHCH 3. Alternatively, 1-naphthol can be treated with excess phosgene to produce 1-naphthyl chloroformate, which is then converted to carbaryl by reaction with methylamine. [5]
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Bromacil is an organic compound with the chemical formula C 9 H 13 BrN 2 O 2, commercially available as a herbicide.Bromacil was first registered as a pesticide in the U.S. in 1961, [2] and by 1974 1,017,000 pounds (461,000 kg) was used annually in the US, largely by government and industry. [3]
