What Is Cyanophos?
Cyanophos, a phosphorus compound with a cyano group (-C≡N), appears as a clear yellow or reddish-yellow liquid. This organophosphorus chemical is formulated into emulsions, hydrates, and powders for use as pesticides and insecticides across various crops including vegetables, fruit trees, legumes, and flowering plants.
While it degrades under sunlight, cyanophos remains a toxic substance, especially to aquatic organisms, prompting the establishment of residue standards for key crops globally due to its environmental impact.
Uses of Cyanophos
Primarily serving as a pesticide and insecticide, cyanophos targets a range of pests, including caterpillars, aphids, weevils, leafhoppers, and many others, exhibiting both insecticidal and ovicidal effects. Its widespread agricultural use has been underpinned by its effectiveness against these pests.
Properties of Cyanophos
