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 ...
Surfactants, solvents, and preservatives are inert ingredients, or adjuvants, that are commonly added to glyphosate-based herbicide formulations. [12] Some products contain all the necessary adjuvants, including surfactant; some contain no adjuvant system, while other products contain only a limited amount of adjuvant.
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. About 2.2:1 is the ratio (by weight) for compounding sulfur and quicklime; this makes the ...
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.
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 ...
They are synthetic organochlorine cyclodiene pesticides used to control subterranean insect pests such as nargles root maggots, mole cricket grubs and weevils, in agriculture. [9] Both are toxic and bioaccumulative. Aldrin does break down to dieldrin in living systems, but dieldrin is known to resist bacterial and chemical breakdown processes ...
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]
Preheat the oven to 400°. In a saucepan, whisk the mole paste with the stock. Boil the mole sauce over high heat, whisking occasionally, until reduced to 2 cups, 25 minutes.
