Farmers looking to dispose of farmyard manures and slurries over
the winter months need to think about what may have gone into it,
where it is going and whether any herbicide used last summer could
affect crops next year.
The warning comes after joint investigations by Dow AgroSciences
and SAC identified instances of damage to potato crops
in 2007 crops resulting from failure to observe label warnings
regarding following crops on grassland herbicides.
“Products containing aminopyralid have warnings that
clearly state that damage can result if susceptible crops,
such as potatoes, are planted on treated land. Similar
restrictions apply when using manures and slurries that
result from feeding hay or silage made using treated grass,” says
Dow AgroSciences marketing specialist Colin Bowers.
“As these issues can affect different fields, or
even different farms, it is important that everyone involved – from
product application to growing susceptible crops on land
treated with either a grassland herbicide or manures – is
aware of the need to check carefully.”
