I used previously only "Feramol" and was surprised that the snail plague has hardly abated (..offenbar "immune")! When I used COMPO Been the next day anywhere to see the "corpses" :-)! Even after a heavy rain, the grain continues to work! I would recommend it to anyone and take themselves nothing else !! Tip: In the evening sow when it is cooler, because the snails come out of hiding :-)! Moreover breitwürfig spread and no "pile" !! So you get caught you better !!
