DPX-Q9H36 and DPX-QKS91 – New complete solutions against grass weeds and broad leaf weeds in corn
Abstract
DPX-Q9H36 (12 % nicosulfuron, 3 % rimsulfuron, 36 % mesotrione) with an application rate of 330 g/ha + 0.1 % (v/v) DuPont™ Trend® represents a new complete solution in corn against grass weeds and broadleaf weeds. DPX-Q9H36 is characterized by a very good efficacy, a wide spectrum of efficacy, a user-friendly application in a single treatment (corn BBCH 10 - 18) with low-input and high plant tolerance. DPX-Q9H36 as a homogeneous blend of water-dispersible granules. Several years of trials demonstrating the efficacy of DPX-Q9H36 especially against difficult to control weeds such as black nightshade (Solanum nigrum), but also against perennial weeds like quackgrass (Agropyron repens) and several millet species such as barnyard grass (Echinochloa crus-galli) and green foxtail (Setaria viridis).DPX-QKS91 (9.2 % nicosulfuron, 2.3 % rimsulfuron, 55 % dicamba), formulated as a homogeneous blend of water-dispersible granules, controls perennial weeds and grasses as well as annual species. The application is in the post-emergence corn (BBCH 12 - 16) with an application rate of 440 g/ha + 0.1 % (v/v) DuPont™ Trend®. Several years of trials demonstrating the efficacy of DPX-QKS91 i.e. against field bindweed (Convolvulus arvensis), spotted ladysthumb (Polygonum persicae) and back bindweed (Polygonum convolvulus), but also against grass weeds such as quackgrass (Agropyron repens), annual bluegrass (Poa annua) and several species of millet.
