There are many factors to consider when deciding on a mixture and application rate. Some of the factors are the plant species to be sprayed or treated, variety of plants in the same area, the stages of growth, the density of the targeted species, and the water/mixture per ha sprayed (calibration).
As an example: Bugweed needs a very low mixture at medium volumes. Bramble needs a high mixture at high volumes (very wet). If you spray bugweed with a "too strong" mixture, the leaves will burn and fall off. The plant will look dead for a while, but soon it will re sprout and form new shoots. It will look as if you gave it fertilizer. So you can see the complexity of mixtures if you have an area with Bugweed and Bramble.
So unfortunately it is not so easy to make general suggestions. We normally suggest to anyone spraying that label recommendations must be followed. However, should a difficult or unclear situation occur, is Dix available to evaluate any requirements/situations and make appropriate recommendations.
