During a winter warm spell, chickweed clumps were dug up and moved to plastic cups inside for two weeks in a sunny window. Chickweed was treated outside with one spray. 6 different herbicides were compared. Chickweed plants were returned to the window for ten days. The plants were placed in order--most effective to least herbicide effects. Results were: most effective to least:
Surge, (lower left)
T-Zone (with surfactant)
Speedzone
a three-way, (upper left)
Confront
T-Zone, plain
UTC (untreated control)
Estimated rate of herbicide solution was calculated at about a half-gallon per thousand sqft. Lowest label herbicide rates were used.
Of course, Confront is no longer labeled for lawns, but some old label formulation was left over from past years.
Photo included, of course.
