MCPA is a herbicide used to control broadleaved weeds in grassland and cereals. Apart from its agricultural use, there are amenity uses (parks, sports grounds, golf courses, roadside verges etc.) and also amateur (home garden) use. There are numerous approved products in Ireland. It is widely used and is highly water-soluble. It would typically be applied in late spring to grassland and spring cereals. There is also autumn use on winter cereals. It can be used on a range of weeds, including ragwort and thistles, and is particularly effective against rushes, which are often a problem on wet pasture land.
Emissions of pesticides to water can come from diffuse routes or point sources (e.g. runoff from farmyards). Diffuse routes of entry include spray drift on the day of application, and/or runoff/drainage in the post-application period, especially if heavy rainfall occurs. The substances most likely to be detected in water are high-use substances that are water-soluble and that are relatively persistent in the water column, such as MCPA and mecoprop. Occasional detections of such substances in water following periods of use are not unexpected, especially if runoff occurs from a hard surface adjacent to a water body. Any exceedance of the drinking water parametric value for MCPA or mecoprop should generally be of limited duration as they are not expected to unduly persist in surface water.
