Ronstar Turf & Ornamental Pre-Emergent Herbicide

Physically controlling and removing weeds in nurseries is a major task that carries a large financial cost. Weeds compete for water and nutrients and can substantially reduce plant growth and quality. Ronstar is a highly selective granular pre-emergent herbicide that can be used at plant establishment. It does not affect root systems and therefore offers a flexible approach to effective, economic weed control, giving faster plant establishment and growth.

Key features:

• Is not taken up by roots - does not affect root systems (no root-pruning) and is not translocated through the plant
• High level of selectivity - allowing use in a wide range of ornamental species
• Kills weeds prior to emergence from soil
• Controls germinating weeds for up to 10 weeks, giving season-long weed control
• Does not degrade after exposure to long periods to sunlight, therefore weed control is maintained for a long period
• Oxadiazon becomes strongly bound to soil humic and clay particles and, therefore, does not leach from the soil under heavy irrigation or rainfall.
• Retains activity over a range of soil types, organic matter and pH
• Degraded in soil via microbial pathways - research shows no evidence of a build-up of oxadiazon in the soil after several annual applications
