Surf-AC 820 is a general-purpose non-ionic surfactant of the alkylaryl polyethoxyethanol type surface active agents.
It can be used with most insecticides, fungicides, herbicides, acaricides, defoliants, desiccants, and wettable powders to improve performance of the active spray ingredient by giving them more uniform distribution and better wetting of the plant surface.
Tordon RTU specialty herbicide effectively kills cut stumps when you are cleaning out fence lines and non-cropland areas.
RTU stands for Ready-To-Use, and that's just what it is. No mixing or measuring is required, and you can use it nearly year-round. Just pour it into the convenient squirt bottle applicator, and go to work.
