Pretty effective devices.Originally Posted by steveo;
Equally effective / useful are plastic 'dabber bottles' which are just shoe polish bottles with the foam applicator tip.
Here you can get new (& empty) ones for free from your local council office for dealing with 'environmental weeds'. Worth asking your local council environment dept.
Fill them with straight glypho (+ optionally some dye) and they are great for dealing with individual weeds (with minimal co-lateral damage) and poisoning cut ends/stumps/stems of woody plants, blackberry, ivy etc.
