Herbicide Selectivity Mechanisms in Plants! How does a herbicide act in selective manner has been an interesting field of study with the weed scientists ever since the announcement of 2, 4-D and MCPA as very successful herbicides to control broadleaf weeds in winter grains. An examination of the available literature on the subject reveals that herbicidal selectivity can be either- [...]
Man has attempted to control unwanted vegetation, the weeds, with some kind of chemical since centuries. But a real breakthrough in the chemical control of weeds was achieved in 1945 with the announcement of 2,4-D and MCPA in the USA and England, respectively, as highly selective, growth regulator type of herbicides to control broadleaf weeds in small grains. It is [...]
