How to kill it

Early de­tec­tion and erad­i­ca­tion is very im­por­tant with this wil­low. Be­gin con­trol at the top of a catch­ment. Treat ev­ery stem.

1. Cut and squirt (sum­mer-au­tumn): make 1 cut ev­ery 100mm around the trunk and sat­u­rate with undi­luted glyphosate (10 ml) or 2, 4-D es­ter (20 ml).

2. Cut stump ap­pli­ca­tion: ap­ply pi­clo­ram gel. Re­move all plant ma­te­rial from site as all cut stems can root where they fall.

3. Bore and fill (sum­mer-au­tumn): make 1 hole ev­ery 100 mm around the trunk and sat­u­rate each hole with undi­luted glyphosate (10ml) or met­sul­furon-methyl 600g/kg (2ml of 20g/l) or undi­luted 2,4-D es­ter (20ml).

4. Frilling (sum­mer-au­tumn): glyphosate (100ml/l) or 2,4-D es­ter (200ml/l).

5. Spray ( full leaf stage only): glyphosate (12.5ml/l + pen­e­trant, to­tal cov­er­age needed) or met­sul­furon-methyl 600 g/kg (35g/100l from Jan­uary to April be­fore leaf fall be­gins).
