Included below are some important training requirements and application reminders for the use of XtendiMax® herbicide with VaporGrip® Technology.
Mandatory training. Under the new Environmental Protection Agency Restricted Use Pesticide label, mandatory training is required for ALL applicators spraying XtendiMax with VaporGrip technology.
Mandatory recordkeeping. Documentation must include daily sprayer cleanout, start and stop times, wind speed, wind direction, temperature at boom height, as well as the type of equipment used to make these measurements. Commercial and non-commercial applicators must complete records within 48 hours of application. Recordkeeping forms can be found at: www.xtendimaxapplicationrequirements.com.
Awareness of nearby susceptible crops. Applicators must be aware of nearby susceptible crops and avoid spraying during environmental conditions conducive to drift and volatility. Do not apply when wind is blowing towards adjacent susceptible crops. Do not apply in temperature inversions. Maintain the required downwind buffer (a minimum of a 110 ft buffer at the 22 fl oz/acre rate and 220 ft at the 44 fl oz/acre rate).
Application timing. Only spray between sunrise and sunset.
Wind speed. Apply when wind speed (measured at boom height) is between 3 and 10 mph.
Ammonium sulfate (AMS) restrictions. Do not use AMS or ammonium-based additives with XtendiMax with VaporGrip Technology.
Tank-mix partners. Use only approved tank-mix partners found at www.xtendimaxapplicationrequirements.com. Refer to all product labels to determine mix order or perform mix compatibility tests.
Application rate. The burndown, preplant, at-planting, and preemergence application rate is 22 or 44 fl oz/acre (only one application of 44 fl oz/acre is allowed); the in-crop application rate is 22 fl oz/acre for crops with Roundup Ready 2 Xtend® and XtendFlex® technology (two in-crop applications are allowed per year).
Spray boom height. Do not exceed a boom height of 24 inches above target pest or crop canopy.
Nozzles. Use only approved nozzles within the specified pressure found at www.xtendimaxapplicationrequirements.com.
Ground speed. Do not exceed 15 mph ground speed.
Spray system equipment cleanout. Ensure that the entire sprayer system is properly cleaned before and after using XtendiMax with VaporGrip Technology.
