Is plot boost absorb thru the foliage of the plants or from the roots of the plants? I have sprayed on the plants and it has dried on the leaves and I don’t think it is absorbing the way that it should. Should I use a surfactant with it?
Yes, PlotBoost is absorbed through the foliage, but it also can be active in the soil. If it has hit the leaves, it will be absorbed. It works just like herbicide such as roundup. You can mix surfactant with the PlotBoost. It will be absorbed just fine, but if you are concerned it is not getting in, you can mix surfactant to increase absorption.
