Cut stump and paste freshly cut base of stems with metsulfuron gel

Basic Growsafe certified
Cut stump and spray freshly cut base with 1g metsulfuron-methyl per 1 L of water

Certified Handler/Experienced agrichemical user
Drill and inject trees with 1g metsulfuron-methyl per 1L of water if safe to do so. Drill 18mm holes (tangentially angled downwards) in a spiral up the trunk. For 50mm stems drill one hole. For 100mm stems drill two holes. For larger stems drill holes 150mm apart.
Foliar spray seedlings with 5g metsulfuron-methyl per 10L of water and 20ml penetrant
