This powder may be smaller than you imagine from the product shot. It contains only 50g of product. However, it is highly concentrated. This one little bottle can be mixed with at least 5 liters of water and will spray up to 500m of land. I mix it for a sprayer and do mostly spot applications along my fences and driveway – This has done a great job controlling weeds around my home, it works quickly and keeps the weeds away for a decent amount of time – they’re always going to come back, but this does a nice job keeping them at bay. This acting on 46 different varieties of broadleaf weeds and grasses.
