Seven steps for dicamba spraying success
As growers and applicators begin rolling their sprayers out of the machinery shed, there are a few things they should keep in mind this growing season to ensure a successful dicamba application:
1) Know your state’s specific regulations
All applicators are required to be trained before applying Engenia® herbicide and some states have additional training restrictions and requirements. Be sure to check with your state’s pesticide regulatory agency for additional training and application requirements or restrictions—including application cut off dates. In addition, only certified applicators may purchase and use any of the approved dicamba formulations.
2) Select the correct nozzle size
One of the most important and first decisions made by an applicator is selecting the correct nozzle size. Applicators can only use approved nozzles which produce large, ultra-coarse droplets when making applications of Engenia herbicide. This approach helps minimize drift by reducing the amount of driftable fines, which are small droplets that are more prone to move off-target. A list of approved nozzle options can be found at EngeniaTankMix.com.
3) Check the wind speed
Wind speed is another important factor to consider to ensure a successful application. Apply Engenia herbicide when wind speeds are between three to 10 miles per hour and when the wind is blowing away from neighboring sensitive crops. Do not spray if wind is blowing toward neighboring sensitive crops (like non-dicamba-tolerant soybeans).
4) Avoid temperature inversions
Spraying during an inversion can result in the off-target movement of small droplets as physical drift which never reach their intended target. Temperature inversions occur when temperatures increase with altitude. Their presence is often indicated by ground fog, smoke not rising, dust hanging over a road, or presence of dew or frost. In order to avoid inversions, confirm that field level inversions do not exist before application. Additionally, applications can only be made during the day from one hour after sunrise until two hours before sunset.
5) Clean your spray system
Comprehensive cleaning of sprayers and filling systems is a crucial element to successful use of a Engenia herbicide. Before and after use, thoroughly clean the sprayer and spray system (including fill lines, nurse trucks, pumps, etc.) by performing a triple rinse procedure using a detergent based commercial tank cleaner during the second rinse. Consider using a dedicated handling system for Engenia herbicide to prevent contamination.
6) Keep detailed records
As part of the Restricted Use Pesticide requirements, keep detailed records of your applications. Be sure to create records within 72 hours of your application and include parameters such as tank cleanout procedures, planting date and buffer zone determination. Recordkeeping forms can be found at EngeniaStewardship.com.
7) Follow the label
Label requirements are the same for all of the approved dicamba formulations. Follow the specific requirements needed for a reliable and on-target application. For additional application questions and information, talk with your local BASF representative.
