Scott from Auburn, Al writes,

What is the difference between Prodiamine 65 WDG and WG within the same chemical?

Both products have the chemical Prodiamine but one is labeled "WDG" and the other "WG". Besides the difference in price, is there types of grass incompatibility or others reasons for what they do?


We are assuming you are compaing the two generic forms of the herbicide BarricadeProdiamine 65 WDG and Resolute 65 WG. The only difference between Prodiamine 65 WG and the Resolute 65 WG is that they are made by 2 different manufacturers. They are both contain the same percentage of active ingredient Prodiamine, treat the same pests and applied in the same way. Resolute 65 WG is made by Syngenta (name brand) and Prodiamine 65 WDG is made by Quail-Pro (generic brand) . WG and WDG both stand for Wettable Dispersable Granule, water-dispersible granules must be mixed with water to be applied. Once in water, the granules break apart into fine particles similar to wettable powders.
