DPX-V9360 efficacy with adjuvants and environment

Adjuvants enhanced DPX-V9360 control of green foxtail in the greenhouse and field as follows: methylated sunflower oil > petroleum oil > nonionic surfactant WK > nonionic surfactant X-77. DPX-V9360 applied at rates that controlled weeds did not injure corn. Green foxtail control with DPX-V9...

Description
Summary:Adjuvants enhanced DPX-V9360 control of green foxtail in the greenhouse and field as follows: methylated sunflower oil > petroleum oil > nonionic surfactant WK > nonionic surfactant X-77. DPX-V9360 applied at rates that controlled weeds did not injure corn. Green foxtail control with DPX-V9360 decreased as the amount of simulated rainfall after application increased from 0 to 4 mm and control increased as a 2 mm simulated rainfall was delayed up to 24 h. The influence of simulated rainfall differed with adjuvants, but adjuvants did not overcome the lower green foxtail control with simulated rainfall. DPX-V9360 was more phytotoxic to green foxtail and redroot pigweed at 95 to 100% than 45 to 50% relative humidity and at 20 or 30 C than 10 C after treatment.
