Q: The herbicide I used this time last year hit my weeds, but it also stopped my turf's growth - even though I used a fertiliser. Why ?
A: Most herbicides operate beneath the ground via root systems, but they cannot distinguish between weed roots and turf roots. The bad news about this situation is that when you treat your weeds, you may also be damaging your turf. This may be why your turf stalled last year, regardless of your fertiliser. Q: Okay, so how do I stop my weeds, but not my turf ?
A: You need to experiment with a different kind of herbicide. For example, Ronstar has been engineered to clean out weeds without jeopardising turf. It does this by operating above the ground on weed shoots, not their roots. And, because Ronstar doesn't have any impact below the ground, your turf is unaffected. Q: When�s the best time to apply Ronstar ?
A: Being a single-application pre-emergent herbicide, Ronstar G needs to be in the ground before weed seeds start to germinate. It is best applied in late winter for summer weeds (that way, you don't have to worry about picking the right application time during spring, a notoriously busy time of the year) or late summer for winter grass. Q: What are Ronstar's key weed targets, or ideal situations ?
A: It’s ideally suited for worn or damaged turf that needs to recover quickly without competition from virile weeds such as Crowsfoot grass (Eleusine indica). Because Ronstar G doesn’t operate through root systems, it’s also ideal for the weed control in newly-sprigged or stolonised areas. Ronstar G is registered for the control of Creeping oxalis and Poa annua throughout Australia. Provided it is applied before germination, Ronstar G provides excellent control for up to 10 weeks, and it also suppresses Su Q: What are Ronstar's application rates for Crowsfoot grass, Summer grass, Creeping oxalis and Poa annua ?
A: Crowsfoot grass and Summer grass: 150kg/ha; Creeping oxalis and Poa annua: 200kg/ha. Q: What is Ronstar's environmental impact ?
A: When used as recommended, Ronstar: rapidly absorbs onto soil colloids; exhibits very low risk of leaching and lateral movement; has minimal impact on flora and fauna; and very low toxicity to fish and birds. Q: How many times should I apply Ronstar, and how long do its effects last ?
A: Only one application is required. It controls different weeds for different periods, but 10 weeks is a reliable overall average for its residual control. Q: What are Ronstar's limitations ?
A: Ronstar is a pre-emergent herbicide that is registered on warm-season turf only. Its effectiveness depends on its granules being in the ground before rather than after weed germination occurs. This means late winter is its ideal application time, so that it is ready to work as the ground�s temperature increases.
