Is acephate toxic to humans?
Health Effects Acephate can cause cholinesterase inhibition in humans; that is, it can overstimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.
Is acephate an organophosphate?
Acephate is a contact and systemic organophosphate insecticide registered in the U.S. in 1973 and used to control insects on field (e.g., tobacco) and food crops (e.g., beans, lettuce, bell peppers), on ornamental plants, sods and turf, in food handling establishments, residential and commercial buildings.
What is insecticide toxicity?
The toxicity of a pesticide is its capacity or ability to cause injury or illness. The toxicity of a particular pesticide is determined by subjecting test animals to varying dosages of the active ingredient (a.i.) and each of its formulated products.
What is the function of acephate?
It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).

The insecticides in the list of 27 include Acephate (already banned in 32 countries as it is toxic to honey-bees), Atrazine (toxic to fish and other aquatic lives), Benfuracarb (banned in 28 countries and not approved by EU), Captan (toxic to fish), Diuron, Malathion, Zineb and Ziram.
Is acephate banned in US?
It is used on food crops, citrus trees, as a seed treatment, on golf courses, and in commercial or institutional facilities. At one time acephate was used commonly in and around homes, but most of those uses are no longer allowed. Acephate has been registered by the U.S. EPA since 1973.
When do you use acephate?
Apply Acephate 97UP when your crops have encountered an insect infestation. Acephate 97 is toxic to birds. Do not apply when bees are actively visiting treatment ares, this product is highly toxic to bees when exposed to direct treatment on blooming crops or weeds. Have on the necessary PPE before mixing and applying.
What is the highest level of toxicity?
Category 1, the highest toxicity category, has cut off values of 5 mg/kg by the oral route, 50 mg/kg by the dermal route, 100 ppm for gases or gaseous vapours, 0.5 mg/l for vapours, and 0.05 mg/l for dusts and mists.
What is entomology toxicity?
Toxicity refers to the innate capacity of a chemical to be poisonous to living organisms.
Is acephate toxic to bees?
Acephate is a broad-spectrum insecticide and is highly toxic to bees and other beneficial insects.
Is Orthene and acephate the same thing?
Orthene controls a wide range of insects, especially aphids on certain ornamental flowers, roses, shrubs and trees. Acephate attacks insect nervous systems. Systemic insecticides generally have longer residual persistence than non-systemic.
Which is more toxic, acephate or methamidophos?
Acephate breaks down to methamidophos in the environment by microbes in the presence of oxygen. 4 Methamidophos is more toxic to birds and mammals than its parent compound, acephate. 1 The oral LD 50 for acephate is 1.4 g/kg in male rats, and 1.0 g/kg in female rats. 1 Acephate is low in toxicity when eaten.
What’s the lowest dose of acephate you can take?
Oral The oral LD50 for acephate is 1.4 g/kg in male rats, and 1.0 g/kg in female rats. Acephate is low in toxicity when eaten. The lowest lethal dose observed in a study of Beagle dogs was 680 mg/kg. Human volunteers ingested a single dose of acephate.
What is the chemical name of acephate insecticide?
Chemical Class and Type: Acephate is an organophosphate insecticide. The International Union of Pure and Applied Chemistry (IUPAC) chemical name for acephate is O,S-Dimethyl acetylphosphoramidothioate2, and the Chemical Abstracts Service (CAS) registry number is 30560-19-1.
Is there any evidence that Acephate is a carcinogen?
Humans The U.S. EPA designated acephate as Group C, possible human carcinogen based on increases in liver adenomas and carcinomas in female mice that ate acephate. No human data were found on carcinogenic effects of acephate. Methamidophos is not likely to be a human carcinogen according to U.S. EPA classification.
