Hardwood Control by Injection With Two New Chemicals
AC 252,925 [Arsenal®], and 3,6-dichloropicolinic acid (XRM-3972) were tested at two different strengths against seven hardwood species. Triclopyr [Garlon 3A®] was used as a standard, making a total of five herbicide treatments. All treatments were applied in June 1983. Fifteen months after treatment, only AC 252,925 gave acceptable kill over the entire range of species tested. Triclopyr gave good control of sourwood [Oxydendron arboreum (L.) DC.], blackgum (Nyssa sylvatica Marshall), and red maple (Acer rubrum L.). Full strength XRM-3972 killed only 17 percent of treated stems.
