That would be in interesting discussion on this board - the use of chemicals to control insects and weeds vs. using organic means.
Discuss among yourselves..
Why don't you start the topic? What's your opinion?
We use mostly 'mechanical' methods now.... mowing weeds and physically spreading manure in the pasture which prevents flies from hatching eggs in it. Up till recently we didn't have a second pasture to rotate to if we used chemicals, but we do now. This spring sometime we intend to spray for some of the more pernicious weeds we have (scotch broom, bracken) and fertilize. After that treatment it will have to sit there through enough rain to make it again safe for the horses to eat.
