Introducing OH2 Ornamental Herbicide

.OH2 is the new pre-emergent herbicide from ICL that is designed to provide safe and effective control of broadleaf and grassy weeds in nurseries.

ICL recognizes that controlling weeds in nurseries is always challenging, and is promoting effective weed management practices including the use of OH2. Dr Samuel Stacey, Technical Manager at ICL has produced a booklet called Effective Weed Management in Nurseries. The book is based on years of research work and provides practical information on managing weeds. It recognises that no pre-emergent used without an effective weed management plan will provide adequate control of nursery weeds.

The central message is that an effective weed management program consists of:

  • Sanitation practices, especially the use of a long term pre-emergent, such as Sierraron 4G, on nursery paths and surrounds
  • Effective hand weeding to ensure that no weeds set seed in your crop
  • The use of OH2 pre-emergent directly after potting

The book has plenty of information on how small changes to your practice can ensure that your nursery saves money on labour and builds a reputation for growing weed free stock.

ICL are presenting ‘Hort Science Live’, where Dr Samuel Stacey will present on Effective Weed Management. Netafim will present on advances in irrigation practices, and Kim Girdwood will present on benefits nurseries gain from running effective trials. This seminar is a “must attend” for owners and management, and will offer practical ways for growers to improve their outcomes.
