Ioxynil
Ioxynil is a Postemergence, post-emergent selective nitrile herbicide. It is used in Australia, New Zealand and Japan to control broadleaf weeds via the inhibition of photosynthesis. It is used notably on onion crops, among others, normally at 300–900 g/Ha. It was introduced in 1966. The supply of ioxynil is decreasing, as of 2019 but the herbicide remains effective. History Ioxynil and bromoxynil (along with 2,4-DB and MCPB) were patented by Louis Wain as joint-head of the chemistry department at Wye College, and coincidentally discovered independently by May & Baker in England screening spare nitriles for herbicide activity, and by Amchem Products Inc in America doing similar screening, all in 1963. Commercial prospects were promising, as cereals could tolerate large amounts, over 2 lbs/ac; even 4 lbs/ac only temporarily scorches. Wain theorised ioxynil and bromoxynil, the nitrile (-CN) group herbicides, because of the chemical similarity to a Nitro compound, nitro (NO2) grou ...
