Vertmax® Duo pigment is the same concentrated pigment plus a unique bio-stimulant package. When you use this at label rates has several plant health benefits. Our blog on salicylic acid for plants explains what this are and how they an improve your turfgrass
For example, bent and winter grass can only utilize a certain amount of light which is in the 400-500 μmols m2 s-1 range. Above this light intensity and turf becomes photosynthetically saturated which can occur during summer months when light intensities are often over 2,500 μmols m2 s-1. This affects turf performance, wear tolerance, and disease resistance.
With the use of a turf pigment, it is able to absorb and transmit a given light wavelength and reflect a different one. So when you use Vertmax® pigments, they still allow for PAR light transmission but at a reduced light intensity. The end result is a healthier turf surface as most UV light is either absorbed or reflected.
