CAS 8065-62-1

Demephion

Description:

Demephion, with the CAS number 8065-62-1, is an organophosphorus compound primarily used as an insecticide and acaricide in agricultural applications. It functions by inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine at nerve synapses, which disrupts normal nerve function in pests. Demephion is characterized by its moderate to high toxicity to various insects, making it effective for pest control. It is typically applied in formulations that allow for effective penetration and action against target organisms. The compound is generally considered to have a relatively short environmental half-life, which can reduce the risk of long-term ecological impact when used according to recommended guidelines. However, due to its mode of action, it poses potential risks to non-target organisms, including beneficial insects and humans, necessitating careful handling and application practices. As with many pesticides, regulatory assessments are crucial to ensure safety and efficacy in its use.

Demephion

CAS: 8065-62-1

Demephion is an oxadiazole, a class of pesticides that are effective against aphids, leafhoppers, and thrips. Demephion is also used as a fungicide. Demephion has been shown to be effective in pest control when applied to crops such as cereal grains, potatoes, sugar beet, rice, cotton and tobacco. Demephion has been shown to have little effect on insects other than those mentioned above. The level of pest control is dependent on the concentration of the pesticide and the length of time it remains active in the environment. Demephion has been found to be effective in laboratory tests using animals and humans; however it should not be used on skin with cuts or wounds. Demephion can cause eye irritation if sprayed directly into eyes with contact lenses intact.
