Ronstar | Turf & Ornamental Pre-Emergent Herbicide 15kg Bayer

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 build-up of oxadiazon in soil after several annual applications From The Garden Superstore
