Keep weeds in check

Weed resistance to chemicals will continually increase. It only takes one weed to survive a treatment for it to pass on the genetic makeup to do so to the offspring. This creates more resistant weeds until there is a whole population of resistant weeds. Applying more herbicide will make these weeds even more resistant. This will happen over again even if the chemical formula for the herbicide is altered.
