Glyphosate is an extremely effective anti-weed agent, but has the disadvantage that certain weeds are resistant, such as dandelion, plantain (plantago) and mosses. The appearance quality of this method leaves something to be desired as a result. Treating with Roundup twice allows (seed) weeds the opportunity to grow in the interim.
The choice in favour of weed control on the basis of glyphosate is frequently price-related over the short term. The WAVE method is able to deliver a better appearance over the year with a manageable budget. Over the longer term, the cost advantage enjoyed by chemical weed control also falls away with respect to the WAVE method.
